Rob KA2PBT no Karen Bartlett Lance Are you posting outcome, or should I just call in also? Rob KA2PBT log is also available from the main project page http://wc2fd.com/prs/ Rob KA2PBT call in Daniel Werbin How do I do this Rob KA2PBT dial this number Rob KA2PBT (877) 854-1570 Rob KA2PBT enter this good Rob KA2PBT 2261641# Rob KA2PBT code Daniel Werbin OK Rob KA2PBT CALL IN PROGRESS Rob KA2PBT Have some of these steel shelves laying around work .... Useful ?? https://i.groupme.com/1125x1500.jpeg.01935cdb953244f5a2fac117357abd58 Asst Project MGR grab them Rob KA2PBT Dan I think that solves your foot plate concerns Project Manager This may not be the best choice for a picture, but there is a ton of angle and c channel. To my eye it's about 5/16". But it will be metric.

Michael Unangst will be 16years too late Michael Unangst late? early? ehhh something like that Rob KA2PBT Ehhh .... yea ... keep forgetting about that part Karen Bartlett Lance (Smart little guy though!) Evan Markowitz I thought makerfaire NYC was in may? Evan Markowitz Oh wait is that World Makerfaire? GroupMe Project Manager is going to 'MakerFaire NYC' Asst Project MGR http://wmfny16.eventbrite.com/ Rob KA2PBT makerfaire NYC = World Makerfaire Rob KA2PBT Since NYC is the capital of the world .... Karen Bartlett Lance Saturday only? 2 day pass? Nick Roschewsk Can I be a driver? Rob KA2PBT @Nick Roschewsk sure .... we just need to find a way to get you there Rob KA2PBT Start googling trains into PENN STATION GroupMe Daniel Werbin is going to 'MakerFaire NYC' Project Manager This is the box Daniel. https://i.groupme.com/1336x752.png.e3c437d4cab44ef2bfd166796691b895 Project Manager https://i.groupme.com/1336x752.png.bd1fd5db6b7b4f109a0df026a14a9730 Asst Project MGR https://www.walmart.com/ip/Stout-Stuff-Metal-Ammo-Box/181890587 Asst Project MGR 50 Cal can Daniel Werbin so the battery itself is 2.75 x 3 x 6.825 Daniel Werbin and we want some additional space around in front of it for wiring, shunts, etc Daniel Werbin but we dont want the case to be too much bigger Daniel Werbin because then its wasted space Asst Project MGR interior 11" x 5-1/2" x 7" Daniel Werbin yeah thats huge Daniel Werbin do they make smaller ones? Project Manager Unknown. So don't get it? Asst Project MGR 30 cal can is 10-x-3-1-2-x-7 Daniel Werbin 30 cal is perfect except about twice the height we need but i guess thats okay Daniel Werbin we can lay it sideways Asst Project MGR http://www.govliquidation.com/auction/search?cmd=results&query=Tyj49f2hkUDhPHRneUfy2OrQ0oz2u-p49xCUu-bi22VV Daniel Werbin okay i just checked in the model Daniel Werbin 30 cal can fits perfectly Daniel Werbin go for it Project Manager Call back Nick. Asst Project MGR BRB Rob KA2PBT http://www.hobbyking.com/hobbyking/store/__18125__Turnigy_Aerodrive_SK3_5055_430kv_Brushless_Outrunner_Motor.html Rob KA2PBT @Daniel Werbin is that the motor you're still looking at ?? Daniel Werbin Yes Daniel Werbin oh it has 6mm shaft not 8, whoops Daniel Werbin oh well we can make a collar adapter for the pulley Asst Project MGR do you have the motor, they are backordered Daniel Werbin all usa warehouses are backordered too, darn. they werent backordered when i specified them Daniel Werbin I guess we can use the big brushless motor from the cnc spindle Asst Project MGR we should get in the backorder cue Daniel Werbin which motor should we use Daniel Werbin the cnc one we have already and its the right shaft dia Daniel Werbin and its more powerful Daniel Werbin well no Daniel Werbin never mind we cant use it Daniel Werbin wrong rpm Asst Project MGR http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=71849 Asst Project MGR what about that Daniel Werbin look at the watts Daniel Werbin not powerful enough Asst Project MGR your killing me smalls Daniel Werbin we can use many different motors but the pulleys we got are for that motor that i picked Daniel Werbin if we use a different motor we need different pulley ratios Daniel Werbin or we need a motor that puts out more then 1600w at around 430kv give or take a few and is cheap Asst Project MGR http://www.hobbyking.com/hobbyking/store/__21869__Turnigy_HeliDrive_SK3_Competition_Series_4962_480kv_700_90_size_heli_.html Daniel Werbin that is bigger Daniel Werbin pricey though Asst Project MGR http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=19618 Asst Project MGR http://www.hobbyking.com/hobbyking/store/multiFinder.asp?t=motor Daniel Werbin if we're going for alternate kv systems then we may as well just use the motor I already own Daniel Werbin and change one stage of the pulley system Daniel Werbin they dont appear to sell the motor i have anymore Daniel Werbin which is 270kv Rob KA2PBT Ok ... So the original motor was 430kv Daniel Werbin yes Daniel Werbin at 22.2v nominal that means roughly 9500 rpm, 9000 when thinking of loading Rob KA2PBT Can we look at a different type of motor .... Some that's not a hobby motor?? Daniel Werbin cant afford it likely Daniel Werbin hobby motors are the largest power to price ratio by far Asst Project MGR by the 74 dollar 480KV motor and lets be done with it Rob KA2PBT Agree Rob KA2PBT Shave $25 someplace else Daniel Werbin ok Rob KA2PBT Can we use a less expensive motor controller?? Daniel Werbin no, our entire advantage hinges on it Daniel Werbin its one of a kind Daniel Werbin we cant easily use a brushless motor without its current limiting feature Rob KA2PBT Great is the enemy of good enough Daniel Werbin we're going to be spending weeks engineering a current limiter for a less expensive esc not meant for this application that will run badly and or blow up Daniel Werbin to save 25 dollars Rob KA2PBT Is there a less expensive off the shelf speed controller that will do an adequate job?? Daniel Werbin not that i am aware of Daniel Werbin this esc is special because its open source and thus is much cheaper then its equivalents Rob KA2PBT What are we looking for ??? PWM ?? Daniel Werbin it has shunts for each phase of the motor that allow it to go into constant current mode. normal speed controllers do not do this. also it is meant for ground applications so its startup alglorithms are meant for having a 'car' and not a propeller Asst Project MGR keep the esc. find the money someplace else Daniel Werbin normal speed controllers shove whatever the motor will take and this will blow the fuse Asst Project MGR or for that matter, lets slap a 550-430K sticker on it and move on with our lives Daniel Werbin i dont think they care if you're within 20-30 dollars of the budget anyway Daniel Werbin by the wording of the rules they care if you're double the budget or something crazy Daniel Werbin they arent going to nickle and dime you for 20 bucks Karen Bartlett Lance We need a new concept name for the project. "Barbie Jeep" is not cool enough and doesn't reflect anything besides humble beginnings. Power Racing Series is about the race itself, not the vehicle or project - plus too functional. We need a catchy project name/team name - short and sweet. Karen Bartlett Lance Press release... quotes from interview.... the whole deal.... but first comes the concept name. Ideas please? Rob KA2PBT Maker Assault Vehicle (MAV) Karen Bartlett Lance Automatically cooler, but let's get some more ideas Karen Bartlett Lance Unless of course we can mount some weaponry Michael Unangst less QQ more pew pew pew Karen Bartlett Lance How about a Super Soaker painted in camo? Asst Project MGR in light of current events, lets not give the NYPD a reason to get triggerhappy #makerlivesmatter Karen Bartlett Lance The voice of reason? Michael Unangst too bad we cant haul it to queens in the deuce😂 Karen Bartlett Lance I don't want to even think about the tolls the traffic for the fuel for that Michael Unangst look on everyones face when we roll in with that...worth it Michael Unangst "i ain't even mad" Asst Project MGR pretty sure we would have to unload the PRS car nightrider style Asst Project MGR you know, very similar to knight rider, just in the dark. Thanks android Karen Bartlett Lance On task, folks - think up names.... MAV is on the table.... Michael Unangst You're welcome. Sincerely, iPhone. Rob KA2PBT The Deuce as a mobile PRS shop .... Priceless ... Michael Unangst I'm in favor. Karen Bartlett Lance (Oversize vehicle lanes on bridges too? Special route?) Still, it would be really cool Asst Project MGR tis only a dream, rabbit Rob KA2PBT https://i.groupme.com/960x720.png.f89856b1d0f244dea3e5af2b78f67036 Rob KA2PBT So Dan ... How are those drawings coming ??? Daniel Werbin working on it sorry. not feeling very good Daniel Werbin will be done soon. working the final design changes in (to change things to the pillow block bearings and steering bushings that you wanted) Zoom..Zoom.. 21 days till World Maker Faire Nick Roschewsk I might be riding down with a kid on my floor . Is it cool if he hangs with out group for the week....and he's a general! Project Manager We already like him better than you. Nick Roschewsk Ouch Rob KA2PBT When do we need to register for the race on 10/1-2 ?? Rob KA2PBT @Daniel Werbin Were you able to finish the drawings for all the parts that need to be cut? What are we doing about motor?? Daniel Werbin making measurements right now but this is the parts for one steering system side Daniel Werbin https://dl.dropboxusercontent.com/u/4963246/PRS/steering%20%20parts%201.jpg Daniel Werbin and the entire hub Rob KA2PBT I think we'll need dimensions ... Daniel Werbin "making measurements right now" Rob KA2PBT Ahhhhh Rob KA2PBT Missed that finer point ..... Daniel Werbin ok, some parts are ready in the drive in a new folder Daniel Werbin let me know if I messed up at all or if something is unclear. Daniel Werbin will make more soon, figured this first batch will keep everyone going for a little while thoug Daniel Werbin h Rob KA2PBT Is there any opportunity to buy some of these parts off the rack ..... or at least redesign them to be made with common tools?? Rob KA2PBT They could POSSIBLY count the amount of labor involved in machining all of these parts. Don't forget about the $500 Purchase rule ... when you enter you consent that they have the right to PURCHASE the car for $500 if they feel you went over budget. Rob KA2PBT So ... what is the "Fair Market Value" of all of these manufactured parts?? Rob KA2PBT https://i.groupme.com/270x380.png.d1e775c3fbea4e1a8ee8cf0c7726bd14 Rob KA2PBT I looked at one online machine shop .... this part ... similar to the hub costs $40 at QUANTITY 25 Asst Project MGR protolabs.com Rob KA2PBT @Daniel Werbin do you have STL files with the right dimensions ??? We could upload and get a quote! Project Manager A 30 cal inside a 50 cal $19.99 Costco. https://i.groupme.com/1336x752.png.ab114a05001d433ab0e4e206aa325cac Rob KA2PBT sounds like a winner Rob KA2PBT I was thinking .. to simplify the front-end .... we should use a SINGLE brake rotor and caliper on the rear drive axle .... I've seen that done before on bigger vehicles than this Daniel Werbin These brakes are very small Daniel Werbin Also you have a very small distance to stop to pass the requirements Rob KA2PBT What do you mean they're small?? Daniel Werbin To fit they are only 140mm rotors Daniel Werbin Meant for scooters Rob KA2PBT Rule for braking is to stop within 18 ft ... doesn't seem hard Daniel Werbin At top speed Rob KA2PBT yea Daniel Werbin Of 25+mph Rob KA2PBT So lets move the brakes to the real axle ... both wheels .... still makes it simpler Rob KA2PBT Post a picture of the brake parts you have. Daniel Werbin I guess. Every PRS build I've seen has front rotors Daniel Werbin I figured it was important Rob KA2PBT stopping is important .... how you stop less so .... if we brake the rear wheels the front wheels can still steer Daniel Werbin I don't think these brakes have enough power to lock up Karen Bartlett Lance If you have greater room on the rear wheels, it may be an improvement. We can be different. Daniel Werbin We already have a rear rotor Rob KA2PBT I'm trying to simplify the front end design. Less is more. Daniel Werbin Well, we can leave it out and then grind the paint off and make that bracket part and reattach the jig and weld it on if it turns out we need it Michael Unangst front brakes means we can do burnouts with it Daniel Werbin That too Daniel Werbin I don't know how well rear brakes will transfer weight to the front Rob KA2PBT OBTW ... what about the motor ... where are we on that?? Daniel Werbin Buying it I guess Rob KA2PBT You found an acceptable replacement?? Daniel Werbin But just so I can get one more word in we are cutting the front brakes? I'm not meaning to be stubborn sounding. I just feel weird removing brakes of all things Daniel Werbin You guys did Rob KA2PBT What guys?? Daniel Werbin You and Nick I think Rob KA2PBT I don't think so Rob KA2PBT I didn't Daniel Werbin You were there Daniel Werbin I think Daniel Werbin When we were talking about how it cost a little more Rob KA2PBT Thought you were doing all of the ordering Daniel Werbin I'll put it in the queue then Rob KA2PBT Let's get everything you need. Daniel Werbin Also I want to hear Nick and Kevin's thoughts on brakes before we don't pull that trigger. Maybe I'm just thinking the car is heavier then it is and my mental physics engine is stuck in car land Rob KA2PBT You're NOT going to get up to 25 MPH on the track ..... ther are very few straightaways .... and if there are they're less that 30 feet long Daniel Werbin Not true I think. Usually they have one long straight that covers the whole front (common design element) and the start finish line is there. I vaguely remember it being something like 15 parking spots long Daniel Werbin Also I've seen cars that had trouble stopping in time with brakes on all four wheels (because of locking up) Daniel Werbin They use smaller wheels though Daniel Werbin 6" Rob KA2PBT So then keep the brakes in the front and simplify the front end design so that we can build it with out machining it. Daniel Werbin There is only 3 parts that need machining Daniel Werbin And they involve the spinning section Daniel Werbin And bearings Rob KA2PBT thats 3 too many Rob KA2PBT There are bearings in the wheels already ... Daniel Werbin I don't know how to have the spindle shaft and bearing holders without meaning l machining then. I can machine the hub bolt holder on my machine Daniel Werbin Those bearings are useless Rob KA2PBT why? Daniel Werbin Crap Rob KA2PBT good enough Daniel Werbin As in you think they are fine or you agree? Rob KA2PBT I think they're fine Rob KA2PBT https://farm6.staticflickr.com/5563/15137668035_25db9f2aa1_z.jpg Daniel Werbin I'm going to have to completely redesign the thing again and every one of those drawings I uploaded is wrong then Rob KA2PBT simple axle coming out welded to a pipe at 90 degrees ... bolt through it Daniel Werbin How do you link the brake rotor to it? Rob KA2PBT you can't which is why I wanted the brakes in the rear Daniel Werbin Well, okay then. Everyone else weigh in and if we all agree I'll delete those drawings and redo it to fit that instead Daniel Werbin can probably delete steering flange brace part. Daniel Werbin probably not necessary Daniel Werbin this is what the assembly looked like after putting it together Daniel Werbin https://dl.dropboxusercontent.com/u/4963246/PRS/steering%20%20parts%201.jpg Daniel Werbin https://dl.dropboxusercontent.com/u/4963246/PRS/steering%20parts%202.jpg Daniel Werbin https://dl.dropboxusercontent.com/u/4963246/PRS/overview%20steering%201.jpg Rob KA2PBT It's beautiful ..... we cant afford it .... Rob KA2PBT we're hacking a powerwheels car not building a F1 Daniel Werbin i guess thats true Daniel Werbin ok Daniel Werbin let me know what the group decides and then i'll redesign it again Rob KA2PBT are you avialable to meet tomorrow evening?? Daniel Werbin ok Daniel Werbin where? Daniel Werbin this is what i was reading when i thought the tires and bearings stunk Daniel Werbin from the mariott chariot Daniel Werbin " The wheels and tires here are made for a hand truck. They’re inexpensive, which is nice, but I shredded the tires in just one weekend and the bearings were shot, too. Probably not meant for the abuse I put them through." Daniel Werbin which uses the same HF 10" tires we got Rob KA2PBT If we get one weekend it's a win!!!! We have another year to get new ones Rob KA2PBT The target shouldn't be first place ... first try. Target should be cross the finish line (period) ... we build off of small sucesses Daniel Werbin okay Daniel Werbin everyone else decide as well and I'll scrap this and do it over Rob KA2PBT OK .. I need to get on the road ... I'll be GROUPME silent for the next two hours ..... enjoy the peace and quiet � Daniel Werbin talking to a friend right now with a cnc plasma table business Daniel Werbin seeing if they are willing to shove our parts on between jobs Daniel Werbin if they are then ALL we have to make are the lathe parts Daniel Werbin good news everyone Daniel Werbin my friend can plasma table the flat parts Daniel Werbin so now my goal is to see how many of the parts we can cram into that operation so we dont have to make them Daniel Werbin anyone have a problem with this? Rob KA2PBT Ok that's good ... Where will you get the metal for him to cut?? Rob KA2PBT Everything we need should be ordered. Daniel Werbin working that out. Daniel Werbin it might pay to have him use offcuts Daniel Werbin gonna see Rob KA2PBT Ok ... But don't forget the schedule .... If we need to can we buy local?? What about the material you need to run through the lathe ?? Rob KA2PBT Ok meeting tomorrow 1900 North Office Daniel Werbin ok. as for lathe material we need just some rod/tube of steel and rod of aluminum Daniel Werbin im gonna work on modelling the rest of the drivetrain Daniel Werbin because we need to combine lathe time with them Rob KA2PBT Do you have a source for the metal ??? Can you specify quantities of what you need?? Daniel Werbin 12 inches of 1/2" steel rod. 12 inches of 2.25" aluminum rod, 6 inches of 1"OD 0.750" ID steel tube (needs to be precise on the ID Daniel Werbin calculating steel plate Daniel Werbin and aluminum plate Asst Project MGR i can cover the tubing Asst Project MGR and rod Asst Project MGR dont forget to allow for material for me to hold on in production Daniel Werbin so if I cover the manufacture of sheet stuff you can cover the manufacture of rod and tube stuff? Asst Project MGR it seems that way Daniel Werbin sounds good Daniel Werbin are the drawings for the tube stuff okay? Rob KA2PBT When will the plasma cut pieces be ready ?? Daniel Werbin undetermined, working that out as we speak. in a few days i think Rob KA2PBT We should order motor, battery, controller ... And any other electronics ... What else are we missing?? Karen Bartlett Lance Steering wheel & seat Karen Bartlett Lance Daniel had also mentioned dashboard indicators - idk what Daniel Werbin electronic components for throttle control (which also control lights if we do that) and a pi and display for it for the dashboard and telemtry (if we do that), the final tires that we are going to use Daniel Werbin electronics for battery safety monitoring Daniel Werbin if we do that Daniel Werbin kill switch Daniel Werbin fuse Daniel Werbin we can dump the pi and display and go with raw leds and needles if we deem thats easier Rob KA2PBT Let's keep it simple for now ... Minimum instrumentation to get the job done Daniel Werbin in that case, there are several paramters you want to know Daniel Werbin battery voltage / amperage, temperature sensor on it (for overheating, can light up an idiot light) motor temperature (idiot light or analog gauge) speed Daniel Werbin and a system error light that is a check engine catch all light Rob KA2PBT Is that all available on the controller?? Daniel Werbin for more detailed information we can rely on the telemetry being sent back and you can tell them over the radio how bad it really is (telemtry is easy to add and only 30 bucks and since it counts as a safety system its not toward the budget Daniel Werbin oh, and temperature of the controller itself. but that can be the same idiot light as the motor overtemp Daniel Werbin my plan is to have a central microcontroller that handles everything. control of lights, dashboard, safety stuff, telemtry, throttle interpretation, etc Daniel Werbin since all of these tasks are very easy Rob KA2PBT Ok if they're easy we can save them for last ... Hard necessary stuff first Daniel Werbin electronics are childsplay Daniel Werbin THOUGH Daniel Werbin I've seen multiple karts fail the endurance race due to badly assembled electronics. Daniel Werbin I think we should do an oshpark order for the main control board to make it nice and strong. I've made about 20 micro controller based oshpark boards so far so I have a known functional library design, so I can whip a board up in a day or two. they have a week or so turnaround Daniel Werbin in this high vibration environment breadboards and nonlocking plugs are a no Daniel Werbin I've read at least five blogs of racers dropping out because of electrical systems falling apart Daniel Werbin including one from MIT Rob KA2PBT Order the boards now Daniel Werbin well let me design it first in that case, so we need to decide a few things right now Daniel Werbin headlights and brake lights, yes or no? Daniel Werbin they are required for any night time stuff (and I think they are really cool) Rob KA2PBT No headlights or brake lights Rob KA2PBT The fair closes before sunset Daniel Werbin but what about for our personal use of the kart during times when its not there? should I put the provisions into the board to handle those things when we have time? Rob KA2PBT We can rebuild the board after the race .... Eyes on the prize .... Nothing except what is necessary ... Daniel Werbin okay. ill throw an expansion header to all unused gpio pins as a catch all in case we think of something Daniel Werbin okay well that should be good then Rob KA2PBT When will you order ALL of the parts we need ??? FYI got shipping info on the pulleys ... Leaving China Daniel Werbin do we have the funds? Daniel Werbin last i recall we did not have enough on the card I was given to order everything Karen Bartlett Lance That card was empty before given to you and has at least a 10 grand limit. Use it wisely and let me know once you go above 600 Daniel Werbin affirmative Daniel Werbin I will paste items here and get approval before ordering though Daniel Werbin http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=70565 Daniel Werbin http://www.enertionboards.com/electric-skateboard-parts/vesc-standard/ Rob KA2PBT If you say this is what we need go for it ... What about battery and how do we charge? Is one battery enough ?? Michael Unangst specs on fuse? I can try to locate a couple "donations" Michael Unangst i can probably assist with some heavy guage cable and connectors. let me know what we needs and I'll take a walk around the shop Rob KA2PBT @Daniel Werbin Mike is a good source for all things power related. Let him know what you're planning Rob KA2PBT September 10, 2016 , 3:01 pm Processed Through Facility GUANGZHOU EMS, CHINA Rob KA2PBT September 13, 2016 , 8:25 am Out for Delivery WASHINGTON, NJ 07882 Rob KA2PBT 3 days from shen zen ... how do they do that .... Michael Unangst planes Rob KA2PBT FYI Dan .... while checking my ebay account these were "suggested" .... Rob KA2PBT http://www.ebay.com/itm/222138351947?_trksid=p11401.c100358.m3753&_trkparms=aid%3D333008%26algo%3DRIC.MBE%26ao%3D1%26asc%3D20150112100450%26meid%3D04e924744a474647ae1f854562fbed66%26pid%3D100358%26rk%3D5%26rkt%3D8%26sd%3D262304801933&ul_noapp=true Rob KA2PBT The only question concern I have about the motor .... Iit seems to be designed for a copter .... props don't have a lot of "resistance" .... will this have enough starting torque to overcome the inertia of the car and a driver?? Rob KA2PBT I'm used to seeing torque ratings on motors Rob KA2PBT WHO IS AVAILABLE to MEET TONIGHT?? Karen Bartlett Lance I will be there. If possible, any receipts for parts ordered could be scanned and posted to the group folder on Google drive, or, alternatively, handed over to me tonight. Rob KA2PBT Hey @Daniel Werbin you awake??? Daniel Werbin Hi Rob KA2PBT Tonight?? Daniel Werbin Yes Rob KA2PBT OK 1900 .... North OFFICE Daniel Werbin okay to answer your question Daniel Werbin the behavior of a brushless motor is not really based on the motor itself, but the controller hooked to it Daniel Werbin on an airplane style speed controller, they have almost zero starting torque and just sorta twitch around a lot and are useless Daniel Werbin but on a ground speed controller (the VESC) the algorithm is a bit smarter and can actually give some torque. still low though, brushless motors without closed loop encoders have low stall torque, their power band starts at 10rpm Rob KA2PBT Soooo our controller supplies high current at start up?? Daniel Werbin because they need to be moving in order to know the rotor position (they use EMF from the third wire to sense magnet rotation) in order to function Daniel Werbin but it limits current Daniel Werbin if we used a normal speed controller the startup pulses into this motor could potentially blow the fuse Daniel Werbin or the speed controller Rob KA2PBT That would be bad Daniel Werbin yes Rob KA2PBT 12T ... Number of turns ... what's that? Daniel Werbin affects things like rpm/v Daniel Werbin how many turns of wire around the core of the motor Rob KA2PBT as opposed to "poles" Daniel Werbin number of turns and number of poles affect rpm/v Rob KA2PBT Ah Daniel Werbin think of poles like the number of commutation cycles it takes to spin once Daniel Werbin its a magnetic gearing down method Daniel Werbin instead of making your motor absolutely huge, simply give it more magnetic poles, so it has to commutate say 24 times instead of 4 Daniel Werbin to spin once Daniel Werbin so now you have much more torque but less rpm Rob KA2PBT I'm getting it Daniel Werbin https://www.youtube.com/watch?v=oFI7VW6WGR4 Rob KA2PBT so turns = coils ? Daniel Werbin turns is how many turns of wire on the coils, poles is how many there are Daniel Werbin this is a motor with a lot of poles Daniel Werbin http://3.bp.blogspot.com/-Eb6CMhowYes/Tk_2v9pcNvI/AAAAAAAAAqo/pcp2Y54YT8g/s1600/0914001437.jpg Daniel Werbin which means tons of torque but low speed Rob KA2PBT so only 12 turns per coil ??? doesn't seem like a lot .... Daniel Werbin its heavy gauge wire Daniel Werbin it has to flow 3500W Rob KA2PBT Any relation to the number of coils vs. magnets ?? The animation has 6 coils to 4 magnets Daniel Werbin magnets set the pole count Daniel Werbin coils are a few less so it 'steps' Michael Unangst https://i.groupme.com/926x1118.jpeg.eb5e7c9e1e31495899eb874bd8066e91 Rob KA2PBT ok .. hitting the road see y'all soon .... Rob KA2PBT On route 31 running a little late I'll be there shortly after seven Karen Bartlett Lance Me too Karen Bartlett Lance Full professor. I believe you're entitled to the full 20 minutes Rob KA2PBT Schedule developed this eve with @Daniel Werbin and @Karen Bartlett Lance Rob KA2PBT https://docs.google.com/spreadsheets/d/1QhDgdkiVXrZIm7tkmw0MOZnG39bnrwIu2i6ErGFB0fE/edit?usp=sharing Daniel Werbin ordering enough components to make 2 electronic control modules, that cool? Daniel Werbin figure we should have a spare since if it dies for some reason the car is completely immobile Rob KA2PBT Yea ... I'm more concerned about the speed controller but spares on that is cost prohibitive Daniel Werbin yeah. with tax and shipping it ate up 150 Daniel Werbin but it only costs 100 for prs budgeting Rob KA2PBT Oooofaaaa Daniel Werbin its actually quite cheap for a ground speed controller Daniel Werbin http://kellycontroller.com/kbl24101x12v-24v100a-bldc-controller-with-regen-p-52.html Daniel Werbin this is a comparable speed controller from commercial Rob KA2PBT The freakin' thing has an ARM processor on it Daniel Werbin an additional 79 dollars, before tax and shipping Daniel Werbin the vesc? yeah its very advanced Daniel Werbin it actually can run an entire os and have flight control software for a quadcopter, on the esc itself Rob KA2PBT It just dawned on me .... Working with you is like working with my team in India .... You're on the same schedule Daniel Werbin lol Rob KA2PBT Can you sync up with me tonight .... Say 2100 hrs ....

Daniel Werbin decent enough since I pulled 95% of its schematic from a working board from a drone Daniel Werbin which was pulled from another working one. the bulk of what you see has been used successfully a few times in my stuff so heres hoping. i played it safe Daniel Werbin could have used less parts but had to be fast Rob KA2PBT Not bad since I've never written a "Hello, World!" program and got it right on the first try. Rob KA2PBT @Daniel Werbin need some of the drawings we discussed last night Asst Project MGR http://www.mcmaster.com/#7767t371/=14607lr Asst Project MGR can we use that instead of the drawn part.

Daniel Werbin I need to bring stuff I made for them in exchange to maybe earn brownie points Daniel Werbin also he wants me around to make sure it all goes well since I'll know, apparently, what the parts should look like Karen Bartlett Lance Tappan zee is,I believe, $5 toll instead of $14 Daniel Werbin thank you guys Daniel Werbin less annoyed going there now Michael Unangst Whats your planned eta to yonkers? Daniel Werbin 5pm Michael Unangst i'd leave ealier if you can, just because you're going east while everyone is heading west doesn't always mean much. Michael Unangst Tap can be a shithole anytime too, but usually not as bad as gwb Daniel Werbin google thinks 1hr 25m so I'm gonna give myself 2 hours Daniel Werbin speed controller here. the company appears to have priority 1 day'd it to me after i expressed concern that prs was coming soonb Karen Bartlett Lance Are there any main components which remain outstanding? Rob KA2PBT Nice of them Rob KA2PBT Don't think the boards came .... but that doesn't impact forward progress Rob KA2PBT plenty of work to do in the meantime Asst Project MGR you funny guy Rob KA2PBT After Dan acquires the plasma cut metal he can start building part of the front end Rob KA2PBT FYI JA jr. planning a special trip into town to drive this thing .....

Daniel Werbin okay Daniel Werbin anyone else want to take part? Karen Bartlett Lance Location? Daniel Werbin the gps doesnt like the shop so Im trying to think of a common location we can all meet up at Daniel Werbin and then you can all follow me in Karen Bartlett Lance (Super secret spy lair? I love this!) Daniel Werbin I wish lol Daniel Werbin hackettstown hd 1900 to then proceed to the shop Daniel Werbin home depot Karen Bartlett Lance Ok Daniel Werbin my good day is now annoying because it appears that the esc is defective dead, or was sent without firmware and is lifeless. I can handle the firmware part (its going to be REALLY annoying but I can handle that part in 2 days when the programmer gets here from amazon) but if its simply defective then we may be hosed. Karen Bartlett Lance Why 2 days? Call them back - totally unacceptable! Karen Bartlett Lance I can yell louder if you need me to Daniel Werbin already talking with them. 2 days because of amazon prime. Karen Bartlett Lance So just unable to *test* at this point? Daniel Werbin yes Karen Bartlett Lance But could be just fine, only won't know because can't program yet? Daniel Werbin its either dead because of a hardware defect or dead because it never got its firmware Daniel Werbin if its the firmware then I have to give it said firmware (it was supposed to come with it) but I need to wait for a programmer to get here from amazon Daniel Werbin if its dead then it needs to be replaced which will take longer maybe Karen Bartlett Lance Okay, well - on we trudge anyway. We will deal with it. I have faith in you. Rob KA2PBT What kind of programmer?? Rob KA2PBT ... yea ... and theres plenty of other stuff that needs to be done before we need a speed xontroller Rob KA2PBT so ... happy you checked it .... but we don't need it till the end of the week Daniel Werbin stlink v2 Rob KA2PBT dafuq is that??? Daniel Werbin the programmer for the stm32 series microcontrollers Rob KA2PBT OK ... backing up a bit ... have you called the ESC company ?? Daniel Werbin already talking with them. Rob KA2PBT OK Daniel Werbin oh my god this forum is so dumb its enraging me Daniel Werbin they have this stupid 'trust' system for new users Daniel Werbin I'm actually talking to the engineer of this product right now Daniel Werbin but I hit a post count limit for new users or something, and he's trying to help me, but I can't reply! Daniel Werbin haha, he realized that I went quiet and suspected that. now talking on email direct. sigh. what a day. Rob KA2PBT good life skills Rob KA2PBT ok ... going mobile and groupme silent ... see you at home depot Daniel Werbin "This is the first time this kind of situation has been raised. On the very first batch (back in 2015) the bootloaders have been badly programmed. But this is the first time I see a firmware not loaded." Daniel Werbin of course its the first time this has ever happened! of course its to us, during a time crunch. Karen Bartlett Lance It will be okay. Just make sure the guy knows how greatly they have inconvenienced you. (And how loudly we are willing to shout it feom the hills of they don't fix it, pronto) Daniel Werbin he's being nice to me, we're trying to figure out if I am gonna ship it back to get it fixed (and incur a week of delay) or try and program it here (if the mcu simply got no firmware then its all good, but if its defective its a waste of time) Karen Bartlett Lance Glad he is working with you. See you at 1900 Daniel Werbin will has ordered another motor controller Daniel Werbin so now we have a spare, and or a functional one, and the dead one can get fixed on its own time, or if it gets fixed in time, we have a spare Rob KA2PBT Yay Will Daniel Werbin karen is delayed slightly by getting stuff from nick Karen Bartlett Lance Actually I'm coming the back way through hope and Independence Karen Bartlett Lance Once Rob gets there call me and we'll figure out if it's better for me to meet you someplace else Daniel Werbin okay Daniel Werbin be there in a minute, was talking to the support company agai Daniel Werbin n Rob KA2PBT I'm at Home Depot ....

Daniel Werbin will weld later. too dark and too tired, been at this for 9 hours now GroupMe Nick Roschewsk added Drew O to the group. Rob KA2PBT You deserve a cookie Nick Roschewsk Me or drew? Rob KA2PBT I said Dan deserved a cookie Rob KA2PBT Hi Drew!! Drew O Hello! Karen Bartlett Lance @Daniel Werbin , I believe I will be working on jeep body construction/painting this week. I am sure you are exhausted from yesterday. @William Browder-Little , I need some time studying what's been done to consider body filler material (wood, plastic, styrofoam, etc) and figure out space for creature comforts (upholstery, padding) and figure out paint surfaces. Either of you have time for me today? William Browder-Little @Karen Bartlett Lance I have a work space with your name on it. I will be available any time after 1PM. Karen Bartlett Lance But.... the Giants are playing at 1...... Karen Bartlett Lance More likely after 4, if that's okay William Browder-Little Of course. That's perfectly fine by me. Karen Bartlett Lance Considering styrofoam for sides, possibly with paper mache over it, plaster, primer for paint tooth. Any combustibility issues with any of this? William Browder-Little Well, if the cooling fails for the FETs... or we manage to toasty toast the windings in the motor. William Browder-Little Paper mache may be the only potential flammability issue. Karen Bartlett Lance If Jeep-ish shape is strong enough in front, then just paint after that. If not, then approximation of 1950s jeep in front with flexible plastic, crack filler, whatever Karen Bartlett Lance Any thoughts as to a different material William Browder-Little We may run into weight issues with plaster as the weight of plaster does add up quickly. Rob KA2PBT Ummm sounds like a bit much .... The spirit is to preserve the original body Karen Bartlett Lance For the sides only Karen Bartlett Lance Hoping the front is still representative Karen Bartlett Lance Did @Devlin M say she already had collected the paint? Karen Bartlett Lance Also, second (body parts) vehicle was discussed, but unaware of location on that. Karen Bartlett Lance @Rob KA2PBT (do I worry you? - sorry!) Rob KA2PBT Basically want to "stretch" the body front to back to fit over the frame ... Daniel Werbin I was literally thinking of cutting the body at the point where it only goes in straight lines and then making some kind of metal bent or plastic thing to fill in the 8 inches Daniel Werbin it doesnt have to be crazy Daniel Werbin some people dont even fill it in Karen Bartlett Lance That's just crazy talk right there! It has to look every bit as cool as it is. Karen Bartlett Lance Will need stencil made, but need sizing first. (M*A*S*H*) Karen Bartlett Lance Do we also want 4077th, or just the mash part? Daniel Werbin well, you guys can do that Karen Bartlett Lance Sure Karen Bartlett Lance Devlin confirmed she has paint - will ask KP for it if timely once he is back Daniel Werbin I'll probably have the gearbox done today when i get back from drone test stuff Daniel Werbin https://i.groupme.com/1632x918.png.12ce5910be574d9390efa1a3a1d408b6 Karen Bartlett Lance Devlin has the primer also, and will be making through license plate once given a measurement. @Nick Roschewsk , how do we include you, you may ask...... well, are ya driving it? Rob KA2PBT Wow ... That brought a tear to my eye Rob KA2PBT @Karen Bartlett Lance You meant to say 721st not 4077th right ?? Karen Bartlett Lance @Daniel Werbin , I would like to be there for the cutting part, Daniel Werbin of the body? Karen Bartlett Lance @Rob KA2PBT , of course! Whatever you'd like it to say - much better Karen Bartlett Lance @Daniel Werbin , yes, I think so. Do you suppose we can do it today? Karen Bartlett Lance So... "M*A*S*H* 721st" @Asst Project MGR . Can you please make a spraypaint template, once I give you a size? Daniel Werbin do not know Daniel Werbin cant guarentee that this drone wont take up all dayu Rob KA2PBT 721st M*C*B Karen Bartlett Lance Yikes! Okay Rob KA2PBT It's all about branding :) Karen Bartlett Lance Okay @Daniel Werbin , that's why I wanted to make sure I could get access with Will. Grateful for your time, and hope you can catch up on your other stuff today. Daniel Werbin who is in charge of making the moxie board and figuring out what we are doing for that? Daniel Werbin they suggest leds. I can whip up RGB leds if you want and can think of a use Daniel Werbin I have 100 of these: Daniel Werbin which are addressable Daniel Werbin https://i.groupme.com/1632x918.png.444c814d5bbc45738fb60dd67c382705 Daniel Werbin we can shove a battery powered uno and fancy flashing weird lighting just to make it more visible and it wouldnt take more then a few minutes. this is on whoever does the sign to decide Daniel Werbin just making it known that it exists Rob KA2PBT How Dan and I work .... https://i.groupme.com/320x301.jpeg.552939a7da7a48be92c917b83543c246 Daniel Werbin just letting whoever is making the sign know that they exist, lol Daniel Werbin not getting involved Daniel Werbin also, rob Daniel Werbin http://www.xkcd.com/1737/ Rob KA2PBT Yea saw that one ... Pretty funny Rob KA2PBT Going groupme silent Nick Roschewsk @Karen Bartlett Lance I'll be driving William Browder-Little @Karen Bartlett Lance What is your ETA? Karen Bartlett Lance Sorry - unexpected in-law time. Call me and we'll figure it out. 862-432-9101 Rob KA2PBT FYI ... We're on the Makerfaire site ... http://makerfaire.com/maker/entry/59250/ William Browder-Little https://i.groupme.com/1334x1000.jpeg.84dfa3544d6d4c93a7d05a0156903df4 William Browder-Little Update: Jeep body has been cut in half to prep for extension, and is now in @Karen Bartlett Lance 's truck for her to make purdy. Rob KA2PBT My schedule for this week: Mon-Thu open for whatever after work (or even during) Fri - going to queens to check us in and then banging up to Worcester to pick up JA jr. and Drew KD2ANZ ... Back in NJ sometime Friday eve William Browder-Little My schedule for this week is sadly far less open - Mon-Thurs 7:30AM-3:30PM at work, then straight to Montclair for classes. Won't be home until 9:30PM. Friday heading to Maker Faire after work to help an exhibitor set up and do their thing. Rob KA2PBT What exhibitor ?? Rob KA2PBT Good morning!' Rob KA2PBT Hey @Daniel Werbin what's on tap today ?? Rob KA2PBT Uhhh @Daniel Werbin ??? You awake yet?? Karen Bartlett Lance The jeep has been pressure washed and de stickered, Karen Bartlett Lance Deciding on logo placement and use (or not) of the color yellow.... if it's 721st, I think we need a bit, no? Rob KA2PBT Yellow for the logo is good Rob KA2PBT maybe on the hood ?? Karen Bartlett Lance Okay, how about accents & trim? Rob KA2PBT be creative � Karen Bartlett Lance Yes, the hood Asst Project MGR please specify what the stencil is exactly supposed to say and the avail space dimensions Daniel Werbin Hi Rob KA2PBT good morning Daniel Werbin Sorry for the late morning. Rob KA2PBT as long as you're rested Rob KA2PBT Soooo .... status report??? Daniel Werbin @Asst Project MGR when can I come to get the pulley bored out to 3/4 Karen Bartlett Lance Not a whole lot of space to work with, but I need a circle for background plus slightly smaller one inside that circle, then "721st MCB". My opinion is that it will have to be in 2 lines, and centered, line over line. So diameter of inner circle needs to fit 2 lines. Karen Bartlett Lance Will give diam shortly. Not home yet Karen Bartlett Lance This will be for the hood Karen Bartlett Lance Honestly it would look a lot better in vinyl Karen Bartlett Lance But I think we can manage with paint Rob KA2PBT @Daniel Werbin in the meantime you could tack up the front end .... ??? Rob KA2PBT also wondering if the oshpark boards came in and if there is a plan B ?? Daniel Werbin they are here Daniel Werbin soldering them tonight Rob KA2PBT K Rob KA2PBT with the exception of HUBS .... all parts have been received and fabbed ?? Daniel Werbin seems that way Daniel Werbin i have to get the pulley bored out still Rob KA2PBT so hubs and pully Rob KA2PBT do you have the rear axle ?? or is that prt of the HUBs? Daniel Werbin yes Rob KA2PBT OK ... so look for things you're NOT blocked on .... � Daniel Werbin do you think I'm just sitting here doing nothing while I wait to get a pulley bored out? lol.. dont worry, everything is going fine Daniel Werbin I'm working on the drivetrain up to the last pulley atm Daniel Werbin and electronics Rob KA2PBT Wellllllll I know how you get distracted by bright shiny things .... and squirrels Asst Project MGR send the pulley to work with @William Browder-Little to give to robert Rob KA2PBT Dan I'll pick the pulley up on my way home from work and deliver to Nick Daniel Werbin https://i.groupme.com/1632x918.png.029d3be7204241c7a76089364127ebb7 Rob KA2PBT Hey ... looks like the picture ... Rob KA2PBT Sooooo what keeps that belt tight?? Daniel Werbin do you see the tensioner? Rob KA2PBT yea is that adjustable? Daniel Werbin not really, unfortunately, as I wasnt even supposed to use a tensioner but I somehow messed it up Daniel Werbin but its fine Daniel Werbin the belt is so rediculously strong that it wont stretch for our use, and its toothed so it wont slip Rob KA2PBT K Daniel Werbin if we need more tension I can put some tape on the tensioner pulley to make it bigger and thus more tension Rob KA2PBT works for me Rob KA2PBT Hey @Daniel Werbin ... I'm going to head out of work soon ... expect me before 1900 .... your house or Will's ??

License plates to be mounted on either the bumpers for the car itself Karen Bartlett Lance WC2FD Karen Bartlett Lance *or Karen Bartlett Lance Idk bumper height for sizing, but very doable, and another branding point Daniel Werbin Who is taking care of the moxie board Rob KA2PBT Sounds like a job for @Devlin M Daniel Werbin They get annoyed if you half ass it I think Daniel Werbin So it's pretty important Rob KA2PBT I soooo don't care about who is annoyed Daniel Werbin Someone here needs to do a big read of the rule PDF of 2016 and make sure we aren't missing anything Rob KA2PBT Another job for @Devlin M .... During FRC she was the rules person Daniel Werbin Ok, sounds good.. is she back yet? Rob KA2PBT She could quote chapter and verse from the rules Devlin M I'll run through it with a close eye, but I'm a little out of touch with our build specifics Daniel Werbin We are good with the build legal front I think, but we need to make sure we aren't forgetting anything else Daniel Werbin Like how we have to say that we hate avocados or something Daniel Werbin Or they know we didn't read the rules Devlin M Ah, ok. Also, I'm a little low on supplies to make a moxie board, unless you want full sorority, ie cardboard, paint, and incredible amounts of glitter.

Karen Bartlett Lance Yikes Rob KA2PBT https://www.youtube.com/shared?ci=XLOBApz7sL0 Daniel Werbin Stopping now.

Daniel Werbin ill pinpoint it tomorrow Karen Bartlett Lance Paint dried and cured nicely. Doing accent pieces in yellow on headlights, "brake lights" and windshield outline. Looks sharp Rob KA2PBT woot Karen Bartlett Lance https://goo.gl/photos/WskGAai5o6D3hhLr9 Rob KA2PBT Seems appropriate Karen Bartlett Lance Screen splining is for all the ragged plastic edges. I rasped what I could, moved to a grinding tool (which will never be the same - pink shreds, haha!). Epoxy should do theteick, then a coat of paint on that. Today, the seat..... Daniel Werbin If you can bring the cushions for the seat I welded the frame for it yesterday Karen Bartlett Lance Yes of course. It's part of my plan but later in the day Rob KA2PBT I have a conf call from 1730-1800 .... I'm heading out right after that if not sooner. Karen Bartlett Lance I haven't worked out a way to attach the back but I was thinking maybe strapping attached to the right and left of the back question and then screwing it onto the frame Daniel Werbin Are the halves extended hey Daniel Werbin Yet Karen Bartlett Lance No but I made the pieces for it out of plastic and they are painted. I am honestly thinking just epoxy Daniel Werbin Yes Karen Bartlett Lance I did not want to do that until we actually attach it to the frame so we get an exact measurement and it's flexible until we do that Daniel Werbin Okay Project Manager DW do you need these ammo boxes today? Daniel Werbin Yes Daniel Werbin I should be home by 3 maybe and I'll head to the shop after Daniel Werbin Can someone bring some scrap metal Daniel Werbin Like 1/8"metal bar and some sheet metal Rob KA2PBT I have two steel shelves in my car 19x24 ish Rob KA2PBT I can also stop at HD on the way Daniel Werbin Need to make bits and bobs like ammo box holder and body mounts Daniel Werbin Get some steel flat bar Rob KA2PBT dimensions ?

Daniel Werbin Maybe we should meet tomorrow Karen Bartlett Lance I don't know, but I think there's a lot that can be done even if just comparing how things will be joined Rob KA2PBT Let's meet even if for a few minutes just to sync up Karen Bartlett Lance For example the safety belt thing. I have a machine with a heavy duty needle that I can sell things in place but I would still need measurements to figure out how we're going to use it Daniel Werbin Ok Project Manager Ammo boxes are in the Shop. What do you need for flat bar? Daniel Werbin Just 1" or 1.5 and 1/8 thick. Need it to make misc parts Daniel Werbin Also gonna weld the ammo can in. We can open it to remove battery Daniel Werbin Forget the hinges and clips Rob Asst Project MGR karen come here for the steel on your way please Project Manager I have 1/8" X 1 1/2" flat bar....how long do you want it?

Karen Bartlett Lance Leaving now also Project Manager I have a clothes washer and dryer in the scrap pile if you want to use them for sheet metal. Karen Bartlett Lance @Asst Project MGR , I am 3 minutes from you. Do you have anything you'd like me to collect and bring?

Daniel Werbin No Daniel Werbin Also you guys can't be here when I'm not here Daniel Werbin Or will Daniel Werbin Since it's someone's house Daniel Werbin I would do the plywood and stapling at your house Karen Karen Bartlett Lance Ok Karen Bartlett Lance But that only holds for the bottom cushion. Did you want the top question done the same way? Because actually I think it's going to end up with strapping and screws unless we can find a chair back Daniel Werbin I'll zip tie a pillow on if I have to Karen Bartlett Lance Laugh all you want because that might happen, but at least it will be covered in green vinyl Karen Bartlett Lance The reason I asked about the plywood is because I don't currently have anything that is usable for the dimensions you've given Karen Bartlett Lance I do have some corrugated plastic which could be used and a couple of other MacGyver items, so I'm just going to throw them in the car and I'll be there Karen Bartlett Lance Plus, Rob will be happy since we may get to waste a couple of Trump Pence signs Karen Bartlett Lance Wood is cut, and upholstering the seat now.

Devlin M do we have a car number? Devlin M nvm. its 721 Devlin M so, we can tape it or glue it, i guess, or we can print it on a sticker.

Rob KA2PBT I think we might have some indoor work to do after dark Rob KA2PBT I'd also like to make a plan for tomorrow .... I'm taking off so I can start working with you as soon as the sun comes up if not before Daniel Werbin After we pack up here at 730 im going home to work on the electronics Daniel Werbin So I can't stay or that won't get done Daniel Werbin Rob can you pick up near to 1" length 7/16"-14 bolts. Like ten of them Daniel Werbin Ok if they are a little longer but 1.5"max Devlin M is this font better? https://i.groupme.com/1920x1080.png.12c9e4e4f88e44a892daa2013b39fd43 Daniel Werbin Also please get 1.5 inch wood screws Karen Bartlett Lance I don't notice that much difference. Check the sample one you had. Daniel Werbin The ones with the hex style if possible Devlin M I only have what microsoft installs by default- I can;t even install free fonts on public computers without an admin password Devlin M its the stupid W Zoom..Zoom.. 2 days till World Maker Faire Devlin M hows this? https://i.groupme.com/1920x1080.png.0f9cfeedad3744dd8de7b86cc381dbf3 Devlin M or with this W Devlin M https://i.groupme.com/1920x1080.png.d43316f5eac448ddb2229176528d483e Daniel Werbin I like the second one Devlin M the second one has been sent to nick Devlin M along with a "PC" copy, if needed Devlin M Is there any other graphics work to be done, while I'm on a roll? Rob KA2PBT "1" length 7/16"-14 bolts" the 14 a quantity or thread ... also .. nuts? Daniel Werbin No nuts. The 14 means course Daniel Werbin Need 10 Asst Project MGR pitch, threads per inch Daniel Werbin Not sure about other graphics Asst Project MGR 7/16 dia 14 TPI 1.0 long from under the had Asst Project MGR head Daniel Werbin https://i.groupme.com/1632x918.png.60547ee80b234c6ca6ea106a37ce38ae Daniel Werbin Don't forget the 1.5 inch wood screws either. Need them for the seat Devlin M https://i.groupme.com/1920x1080.png.2aebed8d722f41168c2626d2628640d1 Devlin M here's a good packing list: http://ppprs.2xlnetworks.org/misc/whattobring Devlin M Its going to rain this weekend, but I can't find anything about what happens in that case Daniel Werbin Slight problem. Nick how can I widen the hole in a steel plate so a 1/4" shaft fits. The plasma hole is small Daniel Werbin https://i.groupme.com/1632x918.png.719cdd59b4db4f459a0529cd3e204221 Daniel Werbin Also @Asst Project MGR did the metal box ever come in Asst Project MGR drill bit Daniel Werbin I don't have a 0.750 drill bit Rob KA2PBT I'll see what I can do ... leaving now Daniel Werbin Also a design problem I've noticed since we didn't want to make a 5th hub. If the handle bars are welded and the steering arm is welded then the top bearing block is trapped Asst Project MGR thats what sawzalls are for Asst Project MGR i have a bit here, but you need a 1/2 chuck Asst Project MGR how about a step drill Asst Project MGR you just need a clearance hole, right clarence? Devlin M How are we doing on safety gear for drivers? Tom Scarince I have a step drill bit goesupta 5/8 Tom Scarince Sorry- 7/8 Daniel Werbin Can it come here tonight Tom Scarince @Rob KA2PBT left yet? Devlin M Do we have to buy tickets to makerfaire? if so, tickets are $10 cheaper online in advance Devlin M https://www.eventbrite.com/e/world-maker-faire-new-york-2016-tickets-25957796468 Daniel Werbin Shop location for anyone's reference Daniel Werbin Rob KA2PBT @Tom Scarince At Washington one stop ... I'll swing by you next Tom Scarince 70 n Lincoln - I'd meet you but I just guzzled a beer Devlin M are we going tomorrow? we can unload, set up, and do some practice laps, apparently Asst Project MGR we have to have a car that rolls before we can worry about that Rob KA2PBT The last time something lay that happened three wise men came from the east Devlin M Advanced Sale rates end tomorrow https://i.groupme.com/600x600.png.783c526ee22549498ad303af931fca4b Rob KA2PBT I think we're getting in free Devlin M %15 discount if you apply (due tomorrow) for a group discount for at least 15. Cheaper for those with student IDs to go solo, though Rob KA2PBT I'm just not sure how many free Rob KA2PBT If I'm not doing anything productive tomorrow I'll drive out to Queens to sign us in Karen Bartlett Lance Along with thar, are we counting seats in cars yet? Because mine is not reliable to go that far, so will need a ride. Rob KA2PBT I'm in for both days with a vehicle that either seats two or four depending upon whether or not I'm transporting the car Rob KA2PBT And on one of those days Lisa is going Daniel Werbin I have lots of space for stuff and one passenger if we want to use mine Rob KA2PBT Devlin your public transportation right? Rob KA2PBT You're Devlin M yeah. a I'm going to be on a lightrail, a train, a subway, and have a walk, though, so I wont be able to carry any supplies Devlin M The rain plan is just "Bring many tarps and duct tape" Devlin M How are we on safety gear? Helmets, goggles, gloves, pads ect? Rob KA2PBT I have JA jr's motorcycle gear Rob KA2PBT https://i.groupme.com/1125x1500.jpeg.fa55949374f8497aaceb6c6459f5d5b1 Karen Bartlett Lance Looks great! I can't wait to see it completed. See you tomorrow Rob KA2PBT We are gathering tomorrow 1030 at the shop Rob KA2PBT Devlin how is your class schedule tomorrow? Rob KA2PBT Also can you check the rules about floorboards and or foot protection Devlin M I've got class until 11:30, then the K2MFF meeting until 1. I'm free after that, though Devlin M Close toed shoes, feet can't dangle or rest om bumpers. Must have foward and side protection of feet, that prevents drivers feet from moving outside the area of the car when viewed from above Rob KA2PBT Thanks I think we're covered .... I was thinking of asking you to take the train into queens to check us in but sound like a lot of work for little gain Daniel Werbin may be a few minutes late. waiting for a part to 3d print for the potentiometers Rob KA2PBT Did you sleep? Daniel Werbin yes. I also do not have the final electronics done for today, HOWEVER, I will definitely have them finished tonight. I already have it all working on my bench. just not enough time to get it ready to drop into the kart programming wise because I dont know the pot positions yet. but I have a backup remote throttle to test with today Daniel Werbin we're all good on that front Daniel Werbin I have a pot I can turn and then it makes throttle happen Daniel Werbin however, I have another problem, I forgot to print the spacer blocks for the wheels Daniel Werbin I am printing one now Daniel Werbin so we can make sure they work Daniel Werbin but we might not be able to bolt all the wheels on and I cant finish printing them because they take 30 min each Daniel Werbin and I wont be here to finish them Rob KA2PBT Ok ... I might get there before you ... I'll setup the canopy Daniel Werbin should I stay here and finish the other 3? Daniel Werbin or come anyway and finish them tonight Rob KA2PBT Can I go in the shop and work?? Daniel Werbin what will you be doing Rob KA2PBT Drilling Daniel Werbin you know which tap drill sizes to use, right? and how deep to drill? Rob KA2PBT 11/64 for 1/4 20 ?? We have that bit ?? How deep ?? Daniel Werbin aprox 1.25" deep on each side. however, you have to make sure you rotate them so that they dont hit eachother inside the part Daniel Werbin they have to pass by eachother Daniel Werbin I think I should be there for that Rob KA2PBT Yea got that Daniel Werbin widen the hole on the steering arm Rob KA2PBT Yea Daniel Werbin and also try and sort everything that we piled in there out Daniel Werbin I cant find certain parts and I have a feeling its because we piled them up Daniel Werbin so sort things into parts and tools again Asst Project MGR #7 for 1/4-20 .201 GroupMe Rob KA2PBT added Tucker KD2JPM to the group. Rob KA2PBT Tucker say Hi when you have a second Rob KA2PBT Wheels up ... Anything from Home Depot?? Daniel Werbin get some threaded 3/8" threaded rod Daniel Werbin several feet Daniel Werbin and more 3/8 washers Rob KA2PBT Nuts ?? Daniel Werbin we have tons Daniel Werbin do I stay and finish the hubs or come without them Daniel Werbin hub spacer Daniel Werbin actually you know what we can probably use bolts as spacers Karen Bartlett Lance I think it would be good if you could have at least one complete wheen done to check for fit. Function may have to wait Daniel Werbin we are going to use bolts. coming soon Project Manager Heading over to the Fab Lab. Rob KA2PBT Grab a quart of oil please Rob KA2PBT For drilling Asst Project MGR use alum tap magic on the hubs (kerosene) Karen Bartlett Lance I am coming from Mansfield is there anything that you need from on my way? William Browder-Little Should be home by 4:30-5PM to help out if help is needed. I can keep folks fed and hydrated at the least.

Today is the day. Wheels up at oh-six-hundred Gavin Where's the rendezvous point? Karen Bartlett Lance For you? I believe you're going in Rob's Car. But I have no idea what town you live in so I will need Rob to weigh in on that. I am at his house at 545 Gavin I'll be there then Karen Bartlett Lance Excellent Rob KA2PBT Good morning!! William Browder-Little @Rob KA2PBT Checking in. Late start for Dan and I. Wheels up in 20 for him and I. Gavin @Daniel Werbin @William Browder-Little what's your status? William Browder-Little @Gavin Waiting on Dan. Tom Scarince Good luck! Godspeed! Make us proud. Or feared. No preference. Gavin Guys rolling yet? Daniel Werbin Yes Devlin M I'm on the move Karen Bartlett Lance Arrived on site and checking in now. Daniel Werbin Eta 824 Gavin @Devlin M please check in Daniel Werbin 3 mins away Devlin M Slight train mishap, I'm almost to NY Penn. I'll be a bit delayed. Rob KA2PBT Go to the front entrance of NY SCI to the unloading line Gavin Dan did you bring an easy up? Rob KA2PBT In Will's cat Rob KA2PBT Carter Rob KA2PBT Ah frig it Daniel Werbin Yes Daniel Werbin Waiting in line Daniel Werbin Of cars William Browder-Little @Rob KA2PBT Inbound to unload. Meet to assist? Gavin We think you can drive right in Devlin M Only for a certain amount of time. If I recall, all cars need to be out of the fair by 10 Rob KA2PBT Somebody go meet them please Karen Bartlett Lance Otw Karen Bartlett Lance Wills work van? Rob KA2PBT Honda element blue Karen Bartlett Lance We've got them and are unpacking Karen Bartlett Lance Sharing space with FUBAR Karen Bartlett Lance Our car fits right in, only looks cooler Rob KA2PBT Awesome Rob KA2PBT Parking is a nightmare different from previous years Karen Bartlett Lance Rob, can you grab that extra sweatshirt? Karen Bartlett Lance Front seat - for Will Rob KA2PBT Yes Rob KA2PBT Is everybody in Karen Bartlett Lance All but Devlin Rob KA2PBT OK she still traveling Devlin M Yes. I'm just about to get on my last train Rob KA2PBT OK let us know when you hear one of us is going to have to meet you probably Devlin M Ok. Eta 9:30 Rob KA2PBT On the BLUE Shuttle Devlin M Off the train now. Google says 7 min walk, then I'll be there. Rob KA2PBT Got to tell us what gate you're at Rob KA2PBT https://i.groupme.com/1125x1500.jpeg.d05b8698702a461397bb7962b5ad04f4 Rob KA2PBT https://i.groupme.com/1125x1500.jpeg.7025b1c5af394d1eb6ff8f09ac24b41c Rob KA2PBT https://v.groupme.com/22123015/2016-10-01T14:57:00Z/31d23c53.568x320r.mp4 https://v.groupme.com/22123015/2016-10-01T14:57:00Z/31d23c53.568x320r.mp4 Michael Unangst any magic smoke yet? Rob KA2PBT Oh yea .... Blew up the motor controller after 4 laps on the first race ..... We currently evaluating the failure .... Michael Unangst well shit... Rob KA2PBT Devlin & Will .... Return to base Rob KA2PBT @William Browder-Little We should go get our cars Evan Markowitz Sorry to hear guys, Tucker actually just texted me Rob KA2PBT We blame you Evan .... Don't know why ... But we have 90 min car ride to discuss that Rob KA2PBT We refuse to concede defeat https://i.groupme.com/1136x852.jpeg.fab3490ec4ab4a0f9cf783be09da8f3e Rob KA2PBT https://i.groupme.com/1136x852.jpeg.eb1fb26a07be48bdb906f5dc835a6096 Rob KA2PBT ... all day people remarked how luxurious our seat looks Tom Scarince Condolences Karen Bartlett Lance It was a great day with a lot learned and so much to do Devlin M Next year's theme: ice cream truck, with actual ice cream to hand out/bribe the judges with Devlin M Just boarded train 3 out of 4 for the night. Are you guys home yet? Gavin Lol. Just got into nj Daniel Werbin 3 minutes from home Devlin M Last train of the night. Then just a half mile walk home! Yay! William Browder-Little @Devlin M Just flopped into bed. Hope everyone made it home safe. Devlin M Just walked in my door myself. Goodnight everyone! Rob KA2PBT Ooooffff I feel like I got hit by a race car .... William Browder-Little Yep, I felt that way too. Decided to stay home today as I felt like I was getting sick. Daniel Werbin I'm working with the manufacturer of the speed controllers to find the optimal setup. I'm also going to try and maybe get us sponsored by them William Browder-Little Now that's thinking with your dipstick. All I'm doing is having pop tarts and chips for breakfast. Daniel Werbin in an hour or so I'm going to come over and try and de-crap the workshop and our tools and stuff and get everything back to normal Daniel Werbin in a week or so I'll start pulling the kart apart for its improvements William Browder-Little If I could mash the heart button in GroupMe like people can on the moxie board I would. Much happiness for workshop de-crapping. Rob KA2PBT Take a day off Dan .... I can help some night this week William Browder-Little Also @Daniel Werbin I was thinking it could be nice to push for more workspace to allow for more people to do more things here at the shop - start turning it into a hackerspace. I started thinking about this when I was thinking how nice it could be to do a monthly meeting or somesuch to keep folks organized and on track with PRS stuff. William Browder-Little @Rob KA2PBT Don't stop him! I fed him sushi last night - he has the power of 20 men now. It's like Popeye. Daniel Werbin well I'm always pushing for more workspace. what did you have in mind? Rob KA2PBT Would LOVE to find quasi-commercial space that isn't tied to someone's residence William Browder-Little We do the toolshed overhaul sooner rather than later. William Browder-Little @Rob KA2PBT I'd like that too - though I'm always pushing to turn unused space into usable space. William Browder-Little And this could always be a stopgap solution for a group space until we have a quasi-commercial space. Daniel Werbin I'd love to make a seperate building on the property somewhere not near anyone else so noise isnt a problem some day in the far off wonderous future William Browder-Little Indeed. That would be nice. William Browder-Little Let's see... 19 members in this group. For a nice Morton building that, when all is said and done, is ~$75k, all I would need is $4,000 from each of you! *makes grabby hands* Daniel Werbin oh boy lol William Browder-Little Actually, $3,947.37 to be more precise. Rob KA2PBT http://previews.123rf.com/images/blamb/blamb1406/blamb140600288/29155994-A-broke-cartoon-man-pulls-his-empty-pockets-inside-out--Stock-Photo.jpg Rob KA2PBT For the record .... Really likin' the ice cream truck ... And handing out ice cream bars for MOXIE! Daniel Werbin the ice cream deuce and a half Daniel Werbin can we throw ice cream bars at the other racers Project Manager This arrived today. https://i.groupme.com/1336x752.png.9e162a75214946749c8348f5a198537d Gavin I don't know of any rules prohibiting two wheels..... Asst Project MGR if you want to live, get to the chopper Asst Project MGR oh wait, wrong kind Daniel Werbin i recall them saying you couldnt have tires inline but I cant seem to find it Daniel Werbin though it does say a minimum of 3 wheels Gavin Put two wheels right next to each other on the same axle..... Asst Project MGR that would be a bitch to steer with that rake angle William Browder-Little We should absolutely throw ice cream scoops instead of bars at the other racers. Have a quick reload ice cream scoop chucker. Like a potato gun but on a NEMA 23 driven turret. William Browder-Little @Project Manager what about having two bike bodies put together? Gavin If you're suggesting we scoop on board, pretty sure we've done some research into that already.... William Browder-Little Oh yeah? Gavin Though personally I'm thinking cannons firing out of a deuce William Browder-Little I must say I do kinda like the way Train Rex worked - aside from the fact that their caboose was entirely out of control... the concept was interesting though. Imagine a two wheeled trailer attached to the back of a deuce with some kind of manned cannon or remotely/locally controlled turret? William Browder-Little We could shoot bouncy balls, ice cream scoops... interesting possibilities. Gavin Pvc and pressurized air can do a lot William Browder-Little Likely quickly shot down possibilities, but... possibilities! Karen Bartlett Lance We could do any and all of those things just for fun if made detachable and done during non-racing time. There were race cars enjoying driving around Maker Fair and drawing fans to the course - great idea to expand fan base and for moxie points Karen Bartlett Lance ....and yes to the ice cream Rob KA2PBT I think there is a no weapons rule Project Manager I would like to have a conference call tonight at 20:00 hrs. Is there anybody who can't make it? Gavin Possibly Rob KA2PBT CONF CALL DETAILS Rob KA2PBT (877) 854-1570,,,2261641# Daniel Werbin right now? Rob KA2PBT yes Daniel Werbin ok one moment Karen Bartlett Lance Oops - I really did intend to be on that call - sorry. Gavin still here. join in William Browder-Little Sorry I missed it - I was sleeping off a stomach bug. Any cliff notes/summary of the meeting? Rob KA2PBT Yea ... You're in charge of keeping Daniel focused. William Browder-Little @Rob KA2PBT You got it. Daniel Werbin talking with the manufacturer of the speed controllers Daniel Werbin they recommended a much better motor, and are sending a special prototype vesc with much beefier fets and also a much higher voltage handling capability. we're going to double up the voltage to 48v William Browder-Little Well... dang. Wow. Much awesome. Tom Scarince Just curious, but was there any event associated w/ the smoke or were you not minding your own business when it "just blew" Daniel Werbin it was slowly losing power Daniel Werbin after talking with some people, I've determined a few factors: Daniel Werbin 1: too long wiring run from battery to motor controller. needs to be as short as possible. so I propose we move to a contactor and remote cutoff switch instead of running feet of wire up and around the car 2: too small capacitors, because of the wiring run issue.  it caused them to ripple and overheat. 3: motor wrong kv, just badly picked, alas. not torquey enough. Daniel Werbin 4: not sensored. so no position sensing for low speed operation. fixing that now Daniel Werbin 5: low switching frequency, I needed to raise the switching frequency due to the motor's low inductance. Daniel Werbin it was abusing the capacitors to hell Tom Scarince OK - that'll do it. I'd point out that breaking the battery connection while the motor is operating can toast the esc- noplace for the energy to go. Daniel Werbin yeah, that makes sense Daniel Werbin the new prototype is also fitted with a TVS thing to handle us using a fuse, I think Daniel Werbin they may be making this custom for our application Rob KA2PBT Instead of a contactor for cut off ... Why not move the switch closer to the battery and use heavier power cable. Simpler ... Less points of failure Rob KA2PBT Switch on top of the ammo can makes sense Daniel Werbin yeah Daniel Werbin as long as its very short Rob KA2PBT Is "short" required because of resistance or some other factor ? Asst Project MGR dont forget we have those nice heavy battery cables from a small tractor. 54"" Asst Project MGR and speaking of capacitors http://hackaday.com/2016/10/03/homemade-capacitors-of-a-mad-scientist/ Daniel Werbin Short is because of inductance. The longer they are the more ripple the caps experience Daniel Werbin We need to find very low ESR caps to use to make a local bank near the esc. We also need to make a pre charging system because of the inrush current to the caps Rob KA2PBT "Will this be on the final exam?" Daniel Werbin Yes Asst Project MGR maybe this time we will pass the final exam "smoke test" Daniel Werbin I hope so. We need to do some fund raising.. I'm out of spare money to sink into this until I get paid back Rob KA2PBT https://i.groupme.com/982x1024.jpeg.d9caa24fb942471fa7a002d1785a22a1 Asst Project MGR @Daniel Werbin please specify a hand throttle Asst Project MGR there seem to be many <$20 using a hall effect sensor Daniel Werbin Yes that is ideal. We want one that does 0 to 3.3v or we can make a divider for a 5v one Daniel Werbin We also need a new brake handle with more travel Daniel Werbin And I'd like to redo the handle bars some day because they are cooked slightly Asst Project MGR we will deal with that when we remove the pedals Daniel Werbin Yeah Asst Project MGR does the caliper assy specify a travel distance Daniel Werbin Also I would like to beef up the front spindles and bearings before we race it next year Gavin I'm still down for differential breaking Daniel Werbin Not really. If we had 50% more we would be golden Tom Scarince Try Panasonic FC series electrolytic for low esr Daniel Werbin Will look into that yes Tom Scarince And so it begins. Ever heard of "minimum viable product"? Daniel Werbin No? Michael Unangst give me specs for caps and any wire that we need. I have access to a decent assortment Daniel Werbin All of them Daniel Werbin Kidding Daniel Werbin Due to the 48v we are actually only running 30a nominal Daniel Werbin What we really need is to find DC contactors rated to 48v and maybe 40a? Daniel Werbin One to pre charge and one to run. The pre charge can be tiny Daniel Werbin It's going through a ballast resistor Daniel Werbin As for caps and wire. 10 or 12ga though a do have a lot. For caps we need at least 60+ v rated very low ESR and a couple thousand uf worth to be safe Michael Unangst I'll look around for contactors as well...most of the stuff in UPS are either 24VDC or 120VAC for contactor pull-down....but i'll see what I find. I'm sure I can find stuff that'll handle the 48V 40A...just control voltage compatability may be a problem Daniel Werbin Like what voltage the coils are? Michael Unangst Yeah, not sure if the DC coils have a voltage range like 20-60VDC or if theyre tight tolerance Daniel Werbin Makes sense Daniel Werbin We'll find out I'm sure Asst Project MGR what are you defining as Low ESR Michael Unangst but I have contactors from tiny little precharge circuit ones...all the way up to ones for 3 phase 480V for machines rated up to like 300KW😏 Michael Unangst ya should see the meter spin when we loadbank test some of those bigger machines at the shop😅 Daniel Werbin I'm not sure. As low as reasonably obtainable. The esc demands massive spikes Tom Scarince Sorry, that was FM series actually Daniel Werbin the fm series doesnt actually come in a high enough voltage rating? Daniel Werbin the caps that the esc uses right now appear to be nichicon vz(� series Daniel Werbin vz-m Daniel Werbin 2x 1000uF 63v Tom Scarince I see Daniel Werbin http://nichicon-us.com/english/products/pdfs/e-uvz.pdf Daniel Werbin i cant seem to figure out where the rated esr is William Browder-Little @Daniel Werbin I may not be able to help you receive money you're owed, but I can throw money at new stuff. Happy to be a source of funding. William Browder-Little Referring to your message you sent about funding yesterday. Daniel Werbin Got paid back already by Nick and Karen Tom Scarince Re ESR, there's a formula like tan Delta = ESR x wC Daniel Werbin Can you give me an example based on the data sheet for the caps the esc uses already? Daniel Werbin What is w? Daniel Werbin I assume c is capacitance Tom Scarince w is my attempt at lower case omega which is frequency Daniel Werbin Oh Rob KA2PBT Isn't lower case omega 2*pi*f ?? Tom Scarince Think yer right Gavin https://en.wikipedia.org/wiki/Angular_frequency Tom Scarince Guess it's been longer than I thought Rob KA2PBT https://i.groupme.com/722x1280.jpeg.ee96c2185b3f48938b5a028361091e04 Tom Scarince So for a 63v 1000uF cap at the spec's 120Hz I get 0.13 ohm... @Rob KA2PBT ? Rob KA2PBT I just got 1.3 ... Let me double check the exponents Daniel Werbin 1.3 would be terrible for esc caps Rob KA2PBT Yea I'm pretty sure 1.3 Rob KA2PBT 1 /(2* pi * 120 * 1000e-6) Tom Scarince And tan d was 0.1 Rob KA2PBT Tan d ?? Tom Scarince 0.1 /(2* pi * 120 * 1000e-6) Rob KA2PBT Ah ... But what is tan d ?? Tom Scarince No one is allowed to question that it comes from the date is sheet Rob KA2PBT https://i.groupme.com/394x398.png.4587100881a846f09db92b7462df2000 Daniel Werbin I want it very badly Daniel Werbin Also I wrote a blog entry on my point of view on the PRS stuff we did and it made hackaday Asst Project MGR feel free to share with the rest of the class Asst Project MGR we now have a cordless portaband for further PRS shenanigans Asst Project MGR cuts 5 x 5 Daniel Werbin http://hackaday.com/2016/10/07/fail-of-the-week-power-wheels-racing-series/ Daniel Werbin Neat Rob KA2PBT Yay??? I think ???? Daniel Werbin Hey FUBAR isn't on hackaday I think. For this PRS. Rob KA2PBT Awesome blog post BTW !! Michael Unangst +1 for your write-up @Daniel Werbin, I just got done reading it. Have a cookie🍪! Daniel Werbin Thank you. I'm hoping to document everything I do in that format Michael Unangst 👍 Daniel Werbin Everything I'm involved in I mean Michael Unangst 🍪 or 🍺, whichever you choose to drown your frustrations in👍😛 Daniel Werbin Cookies for sure Daniel Werbin what if we retroactively call our kart 'what a fiasco' Karen Bartlett Lance Not a fiasco though. Hey, it made it around the track. I am happy. We work from there to improve. Karen Bartlett Lance And yes, celebration is in order. Both success and failure should be respected. October 20th suggests itself.... Asst Project MGR Speaking of regenerative braking: http://www.utilitydive.com/news/first-of-its-kind-rail-energy-storage-project-targets-role-in-caiso-ancilla/417817/ Rob KA2PBT Too soon??? https://i.groupme.com/722x1280.jpeg.13658b2022014e3684b67daa972d9cf7 Asst Project MGR better start making the coffee now............. Gavin Is that chanting i hear? Gavin Deuce deuce deuce deuce Project Manager I'm cleaning house, at this point do we need any parts from a original Barbie car? Pink wheels, steering and such...?? Daniel Werbin get it prepared to make into a deuce? Asst Project MGR sounds like no Asst Project MGR what items do we need to make the 29 happen ; Asst Project MGR Motor Asst Project MGR Hand Throttle Asst Project MGR Brake lever Daniel Werbin just want to put out there that from the 20th to the 27th I'm not here since it seems like planned vacations always hit in the middle of a prs build. I scheduled this one deliberately after I thought prs was done lol.. Daniel Werbin we also need to completely redo the drivetrain reduction since the new motor does not fit where the old one was Daniel Werbin and we need a different ratioa Asst Project MGR well, that pretty much shuts that idea down Daniel Werbin and the old one kinda sucked and stripped its axles Daniel Werbin sorry Daniel Werbin didnt expect an event immediately afterwards Asst Project MGR dont be sorry, have a good vacation and come back to get this going again Daniel Werbin I'll be thinking about it while I'm gone Daniel Werbin I have some things I want to design review with you Daniel Werbin at some point Asst Project MGR ok Daniel Werbin aka do we do belt or chain drive] Daniel Werbin or gear drive Asst Project MGR @Project Manager lets schedule a time Rob KA2PBT No biggie Rob KA2PBT https://i.groupme.com/722x1280.jpeg.85af5c3080e443429f16b0ae9da4d931 Rob KA2PBT FYI .. FUBAR in Pittsburgh .... Rob KA2PBT https://www.facebook.com/fubarlabs/posts/10154049000461818 Rob KA2PBT https://i.groupme.com/722x1280.jpeg.e8ffaaa88ee84e378f8f272a2575394f Rob KA2PBT Just leaving this here for future reference http://www.instructables.com/id/Car-Simulator-Arduino-Pedals/ Zoom..Zoom.. 273 days till World Maker Faire Tucker KD2JPM Who's Zoom..Zoom..? Rob KA2PBT A bot Karen Bartlett Lance A wise mathematician who makes predictions Karen Bartlett Lance Dayton bot? Field Day bot? We got stuffs to talk about, no? Rob KA2PBT I think we need rooms .... Karen Bartlett Lance There was talk about moving the location east of the new venue, convenient to main roads. Pool & free breakfast a plus. We are looking at at least 3 rooms, correct? Let's pick some towns and look online. Karen Bartlett Lance Oops, I just noticed this is on the wrong chat.... Zoom..Zoom.. 272 days till World Maker Faire Karen Bartlett Lance Hello friends... Happy Spring! A fundraising opportunity has presented itself from Hope Township: "If you have a non-profit organization and would like some funds, please see our town clerk about grant money we have available for roadside cleanup." Karen Bartlett Lance ...and we do need dunds, because we still have to reimburse Nick from last October. Plus.... there has been talk of rebuilding and improving our vehicle and it would be nice to have the means. Frelinghuysen also has an open ended date for similar services... will be discussing an early Saturday morning date when snow is gone - get it over with and enjoy your day. Karen Bartlett Lance *funds, LOL Rob KA2PBT The next level ... autonomous https://i.groupme.com/960x1280.jpeg.a832581b31a14b30bff121d45f4dfbe1 Rob KA2PBT So many possibilities.... https://i.groupme.com/1500x1125.jpeg.33eec12be3cd4137901b9427d1d7eb47 Rob KA2PBT https://i.groupme.com/1500x1125.jpeg.82572711901e4d2b98c71445a911bc63 Asst Project MGR It's time to schedule the trash picking to clear the debt for this adventure before gets too hot Asst Project MGR There are outstanding bills Karen Bartlett Lance Have Hope and Frelinghusen reserved. Pick your day and let's go. Karen Bartlett Lance Frelinghuysen pays better, or so I believe. Daniel Werbin how much in debt are we Karen Bartlett Lance The club owes Nick... how much? $230 or something like that? @Daniel Werbin , it was the last reimbursement to you via paypal, so you will both have the amount. I went back into shared files to find it, but can't find now. Daniel Werbin with my new job that wont be so hard to do. maybe I can just give it back so we can use the fundraising for new parts, not just catching up with old parts Karen Bartlett Lance Well, that's not up to me, but I still think it's correct to raise funds as a group for something many of us got to enjoy. Karen Bartlett Lance Plus, several of us have expressed the desire to continue to improve the existing jeep, or perhaps even make a new one, or both. Daniel Werbin if we build another thats fantastic, as for the one we have, I think it doesn't need much to be improved. just some new parts in the drivetrain department which I've already worked with the manufacturer of the motor controller to identify Karen Bartlett Lance Nice Rob KA2PBT FabLabBaltimore Asst Project MGR When? Asst Project MGR The cart needs to come to Hill 721 for selective deconstruction Daniel Werbin yes, it does. we can remove the drivetrain and the pedals and start thinking about a better system for the seat to make it easy to remove Daniel Werbin and we can also start working on making the body more.. sturdy Rob KA2PBT Sorry that last post was supposed to have a picture Rob KA2PBT https://i.groupme.com/1136x852.jpeg.a55c71cb6fce42859b6f4f4fddc33643 Daniel Werbin I think if I'm allowed to, I can make the brushless system work this time. If everyone is hesitant to give that a try again, I understand that also. however, it is also the cheapest since the company already sent a prototype motor controller to replace the blown one Rob KA2PBT You can try whatever you want as long as it isn't the night before Daniel Werbin I plan on it being the month or two before Karen Bartlett Lance No time like the present Rob KA2PBT Then I don't care if it's a dozen trained hamsters in an exercise wheel Daniel Werbin the manufacturer recommended a motor for us to use and a gear ratio based on our weight, voltage, and tire size Daniel Werbin so I need to remake the belt drive (one that wont break this time) and use that motor Karen Bartlett Lance You still prefer the belt drive to a chain one? Daniel Werbin I'm open to chain too but its harder to design for Daniel Werbin and the rpm that the motor runs at is at the high end of what a chain can handle Daniel Werbin and a chain requires special tools to make to length and join together Karen Bartlett Lance If I remember, ours was the only non-chain Daniel Werbin at one point I was designed for chain too but I'm not sure now why I changed, I think it was the cost of the tool to size the chain properly and worries about rpm Daniel Werbin everyone else had larger motors that turned slower Daniel Werbin we have a small high rpm motor Daniel Werbin also, some of the winning cars seemed to run a hybrid. I saw some cars that had belt drive and then chain drive as a second stage Karen Bartlett Lance Nice to keep tweaking though.... and to make any successes or mistakes now, rather than months from now when can't get parts quickly enough if we need Daniel Werbin agreed Karen Bartlett Lance So let's make a plan. Let's pick an eve or weekend and talk, study, design, deconstruct, source parts.... when? Hill 721.....so, @Asst Project MGR when? Asst Project MGR Add it to the agenda for the annual rolling meeting. Report back on the findings. It's unrealistic to schedule a work day before field day. I would like to have a plan in place by then though. Karen Bartlett Lance Annual rolling meeting could well be during field day Tucker KD2JPM Can I come over next time you work on the car? I want to learn a little more to at least become involved. Rob KA2PBT Without a doubt Tucker KD2JPM Thank you, just send me a text beforehand please. Project Manager How are Fridays for everyone? 7pm at Daniel and Will shop. Rob KA2PBT I'm fine Asst Project MGR Fridays work for me, what sort of air compressor do you have@William Browder-Little , i think i could bring the plasma William Browder-Little @Asst Project MGR heh... Yeah don't think I can handle a plasma cutter. I'm using a roofing compressor with 3/8" hose. William Browder-Little Also in two weeks Fridays will work. Right now I have classes Friday night 5:30-8PM. Doesn't mean you guys can't work as long as Dan is there. Daniel Werbin Sounds good to me but yeah I'm not sure we have the air capacity yet Rob KA2PBT what the hell are we gutting? Rob KA2PBT *cutting? Asst Project MGR we need to gouge some welds off. much faster then the wiz wheel Daniel Werbin Can probably do it at your house if we have to Rob KA2PBT I vote for moving the car to HILL 721 for the metal work .... Nick is just better equipped for that Tucker KD2JPM Where is Dan and Wills Shop? Hill 721? And Friday at 7PM confirmed? Daniel Werbin we're on 46 near hackettstown Daniel Werbin hill 721 is.. nicks place Daniel Werbin don't remember off the top of my head where that is in terms of describing it Daniel Werbin near intertest Tucker KD2JPM Doesn't 46 go right through Hackettstown? Daniel Werbin yeah, and the shop is on the 46 towards the field of dreams side Rob KA2PBT You guys are talking about different things ... Tucker if we're meeting up on Friday I'm you're ride no matter where it is Tucker KD2JPM Ok Rob KA2PBT FYI "shop" in H'town ... Hill 721 is in Blairstown Rob KA2PBT http://www.instructables.com/id/How-to-Make-an-Electric-Go-Kart-1 Project Manager Tucker asked a valid question, 7pm on Friday? Daniel Werbin me and will are going to be doing field work on friday, if it doesn't run long and terrible we should be able to do that Tucker KD2JPM Any development on plans for working on the car tonight? Daniel Werbin I'm available if anyone can say when and where and if not at the shop I'll need help moving it Rob KA2PBT No Hill 721 tonight Daniel Werbin ok Rob KA2PBT Is the shop "orderly " Daniel Werbin it was last time I left it Rob KA2PBT Ok let me see what's going on here as far as dinner etc Karen Bartlett Lance @Daniel Werbin , I imagine the initial disassembly of the outer skin and the components which need work has to be done anyway, before any framework cutting/smoothing/changes could be done. Why don't we begin with that, and make a plan for tweaking each of the desired areas? Daniel Werbin that body would probably take 2 minutes to get off the vehicle, I think Daniel Werbin its only held on by a couple of zip ties Karen Bartlett Lance And the working components? Karen Bartlett Lance Steering, motor, brakes, bumpers... Karen Bartlett Lance No matter what, it's a good study for the folks who are new and didn't get to see it in action Daniel Werbin True enough. When would we meet? Karen Bartlett Lance I think we said 7, but you are the one who has to open up the shop, and I believe others are dependent on rides. Is 7 still okay for you? Works for me. Daniel Werbin okay Karen Bartlett Lance Let's film it and put it on your you tube channel Daniel Werbin film what? Karen Bartlett Lance Any part of the work that you'd like. You may find it dull, but kinda cool for first timers. Rob KA2PBT @Tucker KD2JPM I'll ping you after I eat .... figure hour or so Tucker KD2JPM I'm out now. Helping my mom pick up a treadmill in Bangor. Tucker KD2JPM @Rob KA2PBT Rob KA2PBT Doh! Rob KA2PBT Ok Project Manager I'm out too. Still working my way down the highway. Daniel Werbin darn, okay Daniel Werbin so who is actually coming? Karen Bartlett Lance I was just about to get in my car , Karen Bartlett Lance And I'd still like to come if you feel it would be productive Karen Bartlett Lance @Rob KA2PBT ? Rob KA2PBT Just finished eating.... I'll head out in a while .... even if just to break the ice for this season Daniel Werbin I've been here. Will wait Tucker KD2JPM I can come. We're done here. Rob KA2PBT Ok I'll get you Tucker KD2JPM Correction: still out off house Rob KA2PBT Okay.... how far away are you?? Tucker KD2JPM Bangor Tucker KD2JPM Of* Rob KA2PBT ETA on Buckhorn? Rob KA2PBT ??? Tucker KD2JPM Half hour Rob KA2PBT Ok I'll have a cup of coffee Rob KA2PBT I'm in your driveway Rob KA2PBT Meeting of the Minds https://i.groupme.com/1024x768.jpeg.641108cbbfd44ed3a7b06673423d4049 Daniel Werbin i look unhappy because of allergies Project Manager That places looks bigger in pictures. Karen Bartlett Lance The new lighting helps Rob KA2PBT They also emptied it out some Rob KA2PBT http://www.ebay.com/itm/Electric-Scooter-Throttle-Control-Twist-hand-Grip-3-ATV-eBike-X-treme-Taotao-ATE-/222241822716?hash=item33bea517fc:g:NNkAAOSwxH1UFjUG Daniel Werbin I'll get back to you on what voltage we need for our throttle Rob KA2PBT Voltage?? I figured you were just going to use TTL into a microcontroller Daniel Werbin We want to use a voltage generating style to avoid jitter. 0-5v Rob KA2PBT I don't understand what that means. Daniel Werbin Find a hall effect throttle that works on 12v and outputs 0to5v Daniel Werbin Very common Daniel Werbin like electricscooterparts.com item# THR-38 Daniel Werbin we could use that Daniel Werbin and i apologize, it was 0-4v Rob KA2PBT Three Cheers for@Karen Bartlett Lance and@Nick Roschewsk for doing road side clean up today to benefit the cause! Thank You! Tucker KD2JPM Hooray Tucker KD2JPM Sorry I couldn't make it. We're out by sellersville right now Karen Bartlett Lance That's okay @Tucker KD2JPM , there will be another one coming up in Frelinghuysen soon and we will be able to give a bit more notice. Enjoy. Rob KA2PBT https://i.groupme.com/500x515.png.0c0119ab88c54874aa22ff8c03729eb0 Karen Bartlett Lance FYI - just found our that the roadside cleanup in Hope was worth $250. Good money for 2 people to complete in under an hour, right? Doing something good for the town, and at the same time, able to make money for the club. Frelinghuysen is next - but will need to wait till after July 4th. We can gauge interest for dates during FD. Daniel Werbin Sounds great! William Browder-Little Had to be shared. Haven't said hello here in awhile. https://i.groupme.com/524x790.png.bb5d760f147d463090463f572e73511b Rob KA2PBT Well done Rob KA2PBT http://makezine.com/2017/06/08/taking-a-power-racing-car-from-concept-to-finish-line/ Tucker KD2JPM I'm now convinced that when wires break in the middle of the wire, it is the spawn of Satan. Daniel Werbin ? Tucker KD2JPM Well basically, I'm reworking our home audio and there is a break on the middle of the wire for the center speaker Daniel Werbin ouch Karen Bartlett Lance Looking for another evening meeting, but would like to circulate the summary and task list of our last meeting, so we can prioritize, decide what to order, estimate man hours, assign, etc. Karen Bartlett Lance Shared a document: https://s.groupme.com/ycUVEM8 GroupMe Karen Bartlett Lance changed name to Karen KD2HII GroupMe Karen KD2HII added Abbie to the group. Evan Markowitz Recruiting a new driver? Lol Karen KD2HII Yes.... sure... Abbie Unfortunately you are not the first to make that joke Evan Markowitz Well @Rob KA2PBT threatened to put me in the seat but even I have limits, you're a bit smaller than me so it would be easier for you xD I'm too tall now obviously Rob KA2PBT "too tall" ?? Karen KD2HII Nope, you're not. Even I fit into the seat. Daniel Werbin I do too Evan Markowitz "too tall" = desperately trying to avoid being in the driver's seat Karen KD2HII Drivers license? Evan Markowitz None to speak of Rob KA2PBT https://goo.gl/photos/YNVVJAhX98fVzgWF9 Abbie Your a disappointment :) Evan Markowitz You knew that already 😂 Abbie Yes true Michael Unangst scared to drive? Evan Markowitz Nah, just trying to shove away responsibility ;) Abbie Well Your really good at that Evan Markowitz Thanks Tucker KD2JPM What if we made the car autonomous? Daniel Werbin Would be a lot lighter Rob KA2PBT Autonomous is a thing .... it's a different competition Tucker KD2JPM We'll just get a mannequin from kohls Michael Unangst I'll grab one https://i.groupme.com/1125x1500.jpeg.8ed8e198543340e9bb5aae5661325b0c Tucker KD2JPM Thanks Karen KD2HII I think grabbing mannequins is just sad. Grab your honey instead. ;) Tucker KD2JPM But we can only use the autonomous ability if we have a so called "driver" Evan Markowitz I mean, on the way to Dayton we passed a number of shops you could have purchased a.. *cough* mannequin at Abbie "Purchase" Karen KD2HII "Rent" Evan Markowitz "sex doll" Evan Markowitz Wait what Abbie "Wait what" Karen KD2HII Back to the matter at hand.... next meeting for PRS. Is Friday night still best, or are we still recovering from FD? Let's try for Fri 7th then. Would need location. Any takers? Michael Unangst http://2.bp.blogspot.com/_r-hXUYZP_kI/TLZhf7azJwI/AAAAAAAAAvk/YXQHRYjuifQ/s1600/lions+den+sign+1.jpg Michael Unangst @Evan Markowitz that look bout right? they're all over ohio😂 Evan Markowitz You've hit the nail on the head @Michael Unangst Karen KD2HII Because.... sure.... we could explain that to all of your parents..... no problem there...right? Evan Markowitz My dad would laugh his arse off are you kidding?! Karen KD2HII Good for you. And your mom? Michael Unangst might need a permission slip for that field trip🙃 Karen KD2HII I wouldn't want to chaperone that trip, just because I wouldn't want to hear the shot from anybody else. Karen KD2HII (Really Google.... I can't say "shit?" Autocorrect.....) Evan Markowitz What my mom doesn't know won't hurt her :) Karen KD2HII True for all mom's everywhere.... Tucker KD2JPM I will check if I am available the 7th Tucker KD2JPM I won't be able to come to the meeting on Friday Karen KD2HII Not this Friday, but next Tucker KD2JPM That's what I meant, the 7th. I leave the 6th Karen KD2HII Bummers. There will be other workdays this Summer - don't worry. Karen KD2HII Daniel has made his workshop available to us, which is where we met last time. The main task will be disassembling the component parts from the body, so that the body can be reinforced and improved. There will be other jobs, but they are a mystery to me until the tasks are put in order and better described. Rob KA2PBT Hey r we meeting tomorrow?? Karen KD2HII @William Browder-Little ? @Daniel Werbin ? We left the time up in the air. Is 1900 okay? William Browder-Little @Karen KD2HII I won't be around sadly. Tucker KD2JPM Can't make it to meeting Tucker KD2JPM https://i.groupme.com/1136x852.jpeg.91641b7b2c744f6e98bf81ffc821cdd2 Karen KD2HII We'd still like to meet, if Daniel is available. And if not..... we are supposed to deconstruct down to the steel frame for further work to be done. Karen KD2HII Most of it is held together with zip ties at this point, so..... even a 10 year old could..... (nahhhh... I won't go there....) Tucker KD2JPM We do have @Evan Markowitz Daniel Werbin Sorry, i was busy Daniel Werbin I guess it's a bit late now Karen KD2HII Nope. It's for tomorrow. Evan Markowitz We have me for what? Daniel Werbin im good for that then Karen KD2HII We need to deconstruct the PRS Jeep, in order to reweld and strengthen it. We also need to decide future tasks, order of work, and supplies to be ordered. Karen KD2HII 1900, @Daniel Werbin ? And is location okay without Will being there? Daniel Werbin he will still probably be there Karen KD2HII Okay. We'll be happy to see him if he is. Meanwhile, who else is in? Like this post if you want to come and work on it. Daniel Werbin i am unsure about the meeting today. I have a lot i need to do today, and the prs cart is going to be extremely annoying to get out of the garage as it is trapped in there by chris blackwood's milling machine, as well as a parking spot being taken up. Also the shop is quite busy inside so we'd need to work outside, and its.. very wet out.  What did we want to accomplish today? Rob KA2PBT How about some planning Daniel Werbin planning works Rob KA2PBT 'Cuz I keep getting emails about registering so that makes me think scheduling Daniel Werbin yeah. the gist of what needs to happen so far is some meetups and planning, then someone can take the body shell and make it much better while my group works on the car itself Karen KD2HII Was hoping to pass the metal frame over by 7/15. Its a soft deadline, but is that doable? Daniel Werbin we dont need to have the metal frame passed over Daniel Werbin we already determined that it needed so little work that it can be done at my/wills shop Karen KD2HII Great. Then planning it is. If it's the body shell that needs to be improved, would like to get that going also. See you at 7. Rob KA2PBT I'm thinking schedule and task assignment. Rob KA2PBT http://mailchi.mp/makerfaire/wmf17-call4makers-rnd1-closes-sunday?e=4d3a5361a8 Daniel Werbin Just confirming that this is still going on today, yes? Karen KD2HII I hope so cuz I'm just turning onto the road Rob KA2PBT On 46 Rob KA2PBT https://i.groupme.com/1136x852.jpeg.d2af054a52e54bd8a651669c4bbb93fd Evan Markowitz 91 Asbury? GroupMe Rob KA2PBT added KC2WCQ Robert to the group. Tucker KD2JPM How did the meeting go? Rob KA2PBT Good ... important dates: 7/29 trash pickup fund raiser 8/19 integration test 9/4 (Labor Day) Release to beta test Tucker KD2JPM Who's testing it Rob KA2PBT All of us GroupMe Project Manager added Troy Godfrey to the group. Daniel Werbin ok everyone, this link should work Daniel Werbin https://docs.google.com/spreadsheets/d/1IZDCrpenfs55K7YGKlZafwSb3a-25DbwyzW2akS8hmk/edit?usp=sharing Daniel Werbin so far I have the critical items Daniel Werbin its all the critical drivetrain parts plus enough batteries to make 2 packs, which is all we need Daniel Werbin when you go into the sheets, make sure you go to the bottom left of the page and select "sheet 3" as 1 and 2 are old Michael Unangst I am unavailable 7/29 for trash pickup, I have a wedding to attend that day....and in the wedding party Daniel Werbin no worries Troy Godfrey Hi, I’m the new guy. Michael Unangst ahhh....the FNG🙃 Troy Godfrey Lol. Daniel Werbin I have received confirmation from the manufacturer of the motor controller that they want us to have the latest tech. they are shipping over their latest retail motor controller (the really expensive one that replaces the one we have) and then in 4 weeks, they also want to ship us a prototype controller because its even better and because we can stress test it for them. its pin compatible with the other one so it can be very easily swapped out should something happen, but the creator is very confident in it and does not think we will have a problem. Either way, I think we're sorted in that department thanks to them. They are sending this: Daniel Werbin http://www.enertionboards.com/electric-skateboard-parts/vesc-x-programmable-brushless-motor-controller/ Devlin M That sounds really cool of them. Should we ask them if they have a sticker or something that we can put on the car? Karen KD2HII Happy to create a written review from our experience/comments if it helps them sell their product. Love a company that gives superior support like this. Daniel Werbin Yeah ive been asking for stickers, think we will get some Rob KA2PBT Awesome stuff!!! Rob KA2PBT Can we make use of this? https://i.groupme.com/640x654.jpeg.dfdde11bcc734f5bba0e431e3bb131b6 Daniel Werbin hmm Daniel Werbin how long ago was that? Rob KA2PBT Hour Rob KA2PBT I'll just leave this here... Rob KA2PBT http://landspeeder.radioflyer.com Rob KA2PBT https://i.groupme.com/722x1280.jpeg.b7af305b2cd8459bb5ecb1ccae3b5f33 Daniel Werbin big delivery of parts today, motor controller, batteries, throttle, bearings Daniel Werbin going to try and make the power system spin up on my workbench tonight Daniel Werbin https://www.youtube.com/watch?v=moe6dXUZRuc Daniel Werbin that was easy Karen KD2HII Did it generate any heat? And what was the graph? Daniel Werbin no, and I'm not entirely sure but it was cool looking (and I will be sure later) Rob KA2PBT https://i.groupme.com/392x486.png.87f3fd279a0c4a7482b5951a3e8ab6d8 Karen KD2HII That will be us, soon enough Karen KD2HII Status so far on Jeep shell : old vinyl is off, rough edges milled a bit and dremeled. No more sharp, pink edges to cut yourself on. The green looks pretty bad, but resurfaced and enough tooth to grab new paint. Daniel Werbin electronics made a great leap tonight, I have throttle control, a reverse toggle switch, and an arduino that can read data and spit it out onto gauges, right now it reads rpm, input voltage, input current, and a few temperatures. It will also be able to keep track of the battery charge (ie: I've discharged 3.45amp hours so far out of this 4.5amp hour pack, so the battery is only 23% charged) which I can display as a 'fuel gauge' Daniel Werbin all of this is already done, its not a to be programmed idea, its doing it right now as i type this Michael Unangst sounds fast....I personally like this shift pattern 😏👍 https://i.groupme.com/884x1000.jpeg.b34568d428d94d2a8e0b971dfcfdd920 Daniel Werbin I'm gonna have to save that one I love it Karen KD2HII Excellent news! Coming along very nicely. Reminder to all that integration day was set for Friday 8/11 in the evening, and there is more to do between now and then. @Daniel Werbin , how can we assist your efforts? Daniel Werbin right now I'm all good, nick is assisting me this week with nailing all the drivetrain together Michael Unangst I'm also a fan of this one @Daniel Werbin https://i.groupme.com/400x400.jpeg.3bf80e9036584dcf8497eacfd0a69062 Daniel Werbin how is the body coming? Daniel Werbin also yeah, man, do they sell these? Karen KD2HII Wheels/axle to be worked on also, I believe. Michael Unangst @Daniel Werbin ohh yeah👍 Karen KD2HII Today was looking at options for the bumper, and will consult with you probably tomorrow night if you are free. Daniel Werbin sounds good Daniel Werbin https://i.groupme.com/1610x906.jpeg.107e4308ae5443dcb4cd455c909b5248 Daniel Werbin the gauge cluster design so far Rob KA2PBT going to use servos? Daniel Werbin yep Daniel Werbin and the pcb we made last year Daniel Werbin notice the second gauge, the amp gauge, by the way Rob KA2PBT negative to indicate regeneration ? Daniel Werbin yeah Rob KA2PBT https://i.groupme.com/399x481.png.1b1d5334810c4bc5bfb3e9625ac24eea Rob KA2PBT I'll just leave this here ..... and walk away briskly .... Rob KA2PBT https://qz.com/1044197/megabots-is-finally-going-to-take-on-japan-in-the-worlds-first-giant-robot-duel/ Project Manager I have taken on the bumpers. I'm looking at firber glass unistrut.

Daniel Werbin if you don't care about brakes we can totally do that tonight in not much time at all Asst Project MGR we are looking to eliminate show stoppers. Daniel Werbin the only major thing that has to be done is putting that belt tensioner on Daniel Werbin which should be straight forward Daniel Werbin what time did you want to meet up tonight?

Asst Project MGR https://i.groupme.com/510x267.png.a5580bfb148c41f790bf89f905a2f40c Daniel Werbin tonight is better I think. either tonight for not too long or next weekend or during the latter week next week.

Daniel Werbin We are. That's the secondary battery Rob KA2PBT SLA is only for "accessories" Daniel Werbin 48v to 12v dc to dc converters are expensive Troy Godfrey How much power? Daniel Werbin 5 ish amps Troy Godfrey I have various types of dc to dc converters. Not sure what is in stock. I may be able to provide an “engineering sample” Daniel Werbin Let us know! Daniel Werbin That would be cool Troy Godfrey Yeah no problem. Daniel Werbin Putting wheels on it now. About to move under it's own power Daniel Werbin https://i.groupme.com/2016x1512.jpeg.21cc12ac20ce4818a7d5578f82c643ca William Browder-Little https://v.groupme.com/22123015/2017-08-21T00:31:08Z/65d8c5f1.640x360r180.mp4 https://v.groupme.com/22123015/2017-08-21T00:31:08Z/65d8c5f1.640x360r180.mp4 William Browder-Little https://v.groupme.com/22123015/2017-08-21T00:32:35Z/4d6d6f65.640x360r180.mp4 https://v.groupme.com/22123015/2017-08-21T00:32:35Z/4d6d6f65.640x360r180.mp4 William Browder-Little https://v.groupme.com/22123015/2017-08-21T00:32:59Z/36e5589.640x360r180.mp4 https://v.groupme.com/22123015/2017-08-21T00:32:59Z/36e5589.640x360r180.mp4 Rob KA2PBT Hmmmmmm ....... Rob KA2PBT Well ..... better than last year Asst Project MGR Gonna need a better brlt Asst Project MGR Belt Daniel Werbin I think the belt is fine i think i screwed up the tensioner placement Daniel Werbin I'll call you Project Manager To my eye some parts of that drive assembly didn't look square to other parts, or the drive shaft. Michael Unangst @Troy Godfrey ....is "racecar" an acceptable project title on a visit to the stockroom?😂 Daniel Werbin https://i.groupme.com/4032x3024.jpeg.db3fb43430b1413ea6f62fac3a17306f Michael Unangst time to go to chain drive?😳 Daniel Werbin this belt should be able to handle tons of power. my tensioner setup was all fucky Daniel Werbin it was on the tension side, not the slack side, and it was only touching the right half of the belt Michael Unangst https://media0.giphy.com/media/LadTQRTRdxldu/giphy.gif Daniel Werbin thats what I really want Tucker KD2JPM The car or burnout? Michael Unangst yes. Daniel Werbin yes Michael Unangst that's why the front tires on my truck have more tread than the back....side stepping the clutch in 3rd gear is waaaay to much fun William Browder-Little Should definitely mention that the videos don't do the cart justice, especially due to the belt and some fine tuning required on the ESC. This thing was able to haul ass before I got the camera rolling. William Browder-Little As the belt deteriorated and we noticed odd noises as a result, we were rather tame with the throttle. Hence the 2016-like acceleration rate. Rob KA2PBT We're in a good place. Asst Project MGR ill get some new belts going tomorrow Daniel Werbin I'm confident about my tensioner being the cause of this. Once I relocate it and get nick to lathe the thing down so its centered on the belt, I bet it will be good. Troy Godfrey Please see highlighted area in datasheet for this DC-DC converter. - Shared a document: https://s.groupme.com/8cxsKV6 Troy Godfrey let me know if this would meet your needs Troy Godfrey Input 48VDC @ 2.4A (Typical) -- Troy Godfrey Output 12VDC @ 100 Watts Daniel Werbin thats perfect! but now basically i need to make the call if we should switch this late in the game from the 12v batteries we already have Daniel Werbin right now we have a mounted spot for a little 7A SLA to strap in Daniel Werbin https://i.groupme.com/4032x3024.jpeg.8f4e18641a0e4343ac25b3cb8f55fd37 Daniel Werbin and@Michael Unangst donated a few SLAS so we have enough for the race Daniel Werbin but next year's car will definitely use it Troy Godfrey I can donate for the cause -- Asst Project MGR Troy, we would love to have the option. Please and thank you on the sample. Troy Godfrey no problem -- Daniel Werbin thats true. good to have in case something goes wrong with the 12v system Troy Godfrey This is more of a lower end converter -- but it may be all you need considering its application Troy Godfrey let me know where I can drop it off Daniel Werbin yeah it just needs to run some lights and sensors Daniel Werbin we will organize that but probably with the mohrs or kevin or karen is the most likely bet, unless you find yourself near hackettstown Troy Godfrey I work in H-town -- perhaps delivery tomorrow? Daniel Werbin sure! I will be home a little late, will keep you posted Troy Godfrey ok no problem -- if not I can always get in touch with nick, karen, or KP Daniel Werbin thank you! Troy Godfrey Your very welcome! Karen KD2HII Can deliver if need be - I have green vinyl for seat backing to drop off as well. Troy - brown paper package pickup at place of business or auto is my MO (LOL!) Troy Godfrey @DAN Troy Godfrey @Daniel Werbin When are you free for me to deliver the supply? Daniel Werbin I'll be home in about half an hour Troy Godfrey I can always drop it off after work since I work in hackettstown Troy Godfrey ok no problem Daniel Werbin Sweet Daniel Werbin Thank you Troy Godfrey address on qrz page? Daniel Werbin I'll send it when i get home but if the address is 166 Mansfield then yes Troy Godfrey it is Asst Project MGR @Troy Godfrey Leave it behind the Palm Tree in the shape of the Giant W Troy Godfrey I will make it into a geocache Troy Godfrey with a enigmatic riddle and 4 digit grid coordinate Troy Godfrey people are into that... Troy Godfrey @Daniel Werbin On my way. 5 min ETA Daniel Werbin Okay Daniel Werbin Troy Godfrey Arrived Troy Godfrey I’m outside in Chev Volt Daniel Werbin Stand by Daniel Werbin Are you moving Daniel Werbin I think you just left my parking lot Troy Godfrey Sorry I thought the apartment might be around back but I saw you now anyway Daniel Werbin Call-out to the group, does anyone have a large bike brake lever Daniel Werbin Our scooter plastic one is inadequate. We need something more substantial off of a bike Rob KA2PBT Maybe ... some old bikes in my shed .... been saving them for just this reason Rob KA2PBT will check tonight Daniel Werbin Okay, while we wait for belts i want to get that done so whoever can get that lets arrange it Michael Unangst think there may be some in my mom's shed too? Brian would know, @Daniel Werbin Daniel Werbin He's somewhere else but I'll bug him about it later Project Manager How do we fill tires with air when we are on the road? Rob KA2PBT we've never had a car rolling long enough to have that problem. Daniel Werbin With a bike pump or 12v pump Tucker KD2JPM I've got a 12 pump that plugs into the lighter socket of a car Rob KA2PBT Then we need 12V ... and I don't think the power converter on the car could drive the pump. I like the low tech approach ... hand pump. OBTW do we need more wheels? Tucker KD2JPM The PRS car or actual car? Daniel Werbin Yes we need more wheels Daniel Werbin We have ac power at the place just bring a ham power supply Rob KA2PBT Let's start a list of "Things to bring" Rob KA2PBT https://docs.google.com/spreadsheets/d/1CK-SSr9XR3dBI2oZpm03aySa8zNtzLzmK-SWsvF6ETY/edit?usp=sharing Tucker KD2JPM If there is AC there, we just bought a 2 gallon air compressor, that might be better. Daniel Werbin That's true Tucker KD2JPM Also, we found out it shouldn't be used to fill big tires. For example. It will not fill the tire of a dually to 80psi. Daniel Werbin We operate at 15psi Tucker KD2JPM Feasible Rob KA2PBT Sometimes less is more Tucker KD2JPM Yes, because youre not filling a truck tire to 80 psi. We were only able to fill it to 20 psi before the friction made it smoke Tucker KD2JPM But it's fine Daniel Werbin Pfft Project Manager This went a lot of directions. The reason I brought it up was so we consider the pneumatic tires on the cart. We don't want to run them on low air pressure, ever. They need 30psi. A hand pump seems the best all-around choice. Daniel Werbin Yeah Karen KD2HII I was asked today weather we are considering hotel rooms for overnight or if we would be coming back and forth for Sunday. Karen KD2HII I know I would want to be there on Sunday if we do well enough on Saturday Daniel Werbin Makes sense Project Manager Tire pump. https://i.groupme.com/1002x1781.jpeg.2ad8e9d0835f425c8108247828640fcd Asst Project MGR there is a HF in Red Hook and Hempstead Asst Project MGR homie aint goin to da bronx Rob KA2PBT What size wheels I'll pick them up but they're going to need to be modified Daniel Werbin they dont need to be modified thankfully. the rims are pretty solid, the only things that we need are the tires and inner tubes Daniel Werbin https://www.harborfreight.com/10-inch-pneumatic-tire-30900.html Daniel Werbin get as many spares as you feel like getting Rob KA2PBT http://hackaday.com/2017/08/24/mini-oscar-mayer-wienermobile-takes-moxie-in-kc/ Rob KA2PBT Competition is fierce Karen KD2HII We will need to think of a moxie campaign of our own. Find some fans and endear ourselves to them. @Devlin M , what say you ? Karen KD2HII (M*A*S*H 721? Maybe?) We need to get into their heads..... Devlin M Well, if we have time, I still stand by the "give ice cream to small children" campaign Rob KA2PBT They would need some sort of 721 flair ..... i.e. camo wrappers or 721 branding Rob KA2PBT A nerf machine gun mounted on the front of the car for the Moxie run might be good too.

KC2WCQ Robert What are the rules for helmets? Rob KA2PBT You need one. I have to double check the rules ... might need to be DOT certified.... you thinking about your "steel pot" Rob KA2PBT @Daniel Werbin I'm around all day .... I can deliver if needed KC2WCQ Robert Yup KC2WCQ Robert Must be DOT Daniel Werbin Will just bought one Rob KA2PBT Thank You @William Browder-Little Daniel Werbin still want me to head up today@Rob KA2PBT or wait to tomorrow? Rob KA2PBT You can come now Daniel Werbin okay cool. see you in.. idk, roughly 20-30 mins Rob KA2PBT Okey doke Daniel Werbin actually belay that. ill come tomorrow.  something i didnt think I had to do just happened so never mind Rob KA2PBT Ok they're here if I go anywhere I'll leave them under the bear that looks like a rock. https://i.groupme.com/1125x1500.jpeg.6d77b2ad3c50403eb10aff1bf1e240e9 Daniel Werbin look great Michael Unangst not under the rock that looks like a gnome? Rob KA2PBT Yea ... more likely.... Project Manager So, is there a active list of what left to do on the car. I expect to be there tomorrow to do some more cart work and the rear bumper. Daniel Werbin ill be with nick tomorrow getting the belts and figuring some stuff out but the cart is at the shop and ready to have the bumper put on, yeah Project Manager How is the brake handle doing? Daniel Werbin i got the new handles from rob, I'm going to leave them in the shop to either let you fiddle with them or I will later Project Manager OK, Ill look. Test drive this weekend?? Daniel Werbin sounds about right Daniel Werbin procomm wants to send me to spain square when makerfaire is supposed to be. its not confirmed yet and I'm going to do my best to get it shifted a week or two but if I cant, we need to figure out whats gonna happen Tucker KD2JPM Get the smallest person to drive Tucker KD2JPM But what you should do is you could tell two or three people everything you know that they don't so we have a "Backup Werbin" Daniel Werbin yeah, ill try to write up some documentation on the cart Daniel Werbin hopefully we don't need it Rob KA2PBT To borrow a quote from @Project Manager "A you fuckin' kidding me?!" Daniel Werbin im trying to avoid it overlapping but i may not have a choice Michael Unangst I'm sure we can come up with a good excuse to get you on the no fly list Daniel Werbin ha Tucker KD2JPM He isn't on one already? Michael Unangst 🙃 Karen KD2HII Work session?... Road test? Driver try-outs? Project Manager Daniel? Daniel Werbin Hi Daniel Werbin Anyone want to do anything tonight or Sunday Asst Project MGR I will be across the way in Mansfield and can stop over Daniel Werbin When Asst Project MGR I'll be there between 6-10 Daniel Werbin Ok i should be there around 7 Karen KD2HII Okay, dropping off the body to you then. Do you still have the license plate? Not with me, so hoping.... Daniel Werbin Hey Nick did you come. I ran late Daniel Werbin I'm not sure if i have it Daniel Werbin What time are you coming down by the way? Karen KD2HII @Daniel Werbin , I dropped the shell and extra paint off at the workshop, and had a short visit with Will. Stopping at Home Depot in any case. Daniel Werbin okay, cool. sorry, i fell asleep briefly Rob KA2PBT I am at the shop I'm all alone Karen KD2HII Haha! I stopped at Donaldsons, & now Home Depot.... Daniel Werbin im on my way Rob KA2PBT Dry fit https://i.groupme.com/1136x852.jpeg.84814d3bae8642458e3a2403fa6a9b44 Project Manager I think the bumpers stand out to much. How do we paint fiberglass? Karen KD2HII Spray primer should do, then camo Daniel Werbin The body will sit forward more when its actually mounted Karen KD2HII Black will make a better choice though. Less complicated touch ups for an area likely to get scratched up and battered a bit Project Manager DW can you use this box? https://i.groupme.com/1781x1002.jpeg.1ae464ea234843db8196edfb56ff2eb3 Daniel Werbin im looking for a plastic box that is narrower right now Project Manager I may have 6 x 6 x 6 pvc box. How is that? Daniel Werbin that sounds better Project Manager I'll look. Project Manager Karen and I mounted the aluminum frame to the cart today. We also vacuumed 40 lbs of metal chips off of the cart. More to follow. Daniel Werbin cool Daniel Werbin sorry that I wasnt there, I was running around getting a radiator for my car Project Manager Loose small parts are in the pockets of the cart handle. Karen took the bumpers to paint them black. Daniel Werbin did you mount the back one yet? Project Manager No, I'm waiting for the body first. I have a idea for connecting the body to the frame, and such. Daniel Werbin I know that I wanted to make the rear half of the body attach to the seat Daniel Werbin so it tilts back with the seat when you tilt it Project Manager At this point I'm not seeing it. Daniel Werbin like you cant visualize it? Daniel Werbin I already planned it with karen and rob in person I guess you're the only one who hasn't seen it yet Project Manager I'll wait and see. Karen KD2HII The hinge on the rear makes the mounting location for the rear of the car difficult for anyplace else but directly to the seat itself. Asst Project MGR something like this would make the body easier to remove from the seat Asst Project MGR https://www.mcmaster.com/#thumb-wheels/=198ae8r Asst Project MGR https://www.mcmaster.com/#thumb-wheels/=f7c262a900fd4065b6585c14e5f911ebj75iiz7n Daniel Werbin yeah thats basically what I was thinking. though if its mounted to the seat you shouldn't need to remove it because when you want to access the rear electronics, the body tips out of the way with the seat Project Manager What are we planning on getting done this week? Rob KA2PBT My biggest concern at the moment is shaking out drive train issues .... like making sure we don't chew up belts Rob KA2PBT I didn't see a fuse holder ... is that still there??

Send the spare alum bearing holder home w Karen to be trimmed Daniel Werbin okay. is she coming today? Asst Project MGR Pretty sure they are there now Daniel Werbin oh Daniel Werbin wait what? Daniel Werbin karen is at the shop now? Karen KD2HII I was. KP did a lot as far as the placement of the outer shell of the car. Also, some decisions were made about the locations of the bumpers and means of mounting them. We made more room for the brake cable and did some figuring on the side profile also. Sorry to have missed you @Daniel Werbin . Daniel Werbin no worries, sounds good Daniel Werbin Body looks really good, don't see anything wrong with it's placement Karen KD2HII I liked it too. Not completely symmetrical, but good shape Rob KA2PBT Bah! Is the Mona Lisa symmetric?? Do you think Picasso was concerned about symmetry? Keep in mind FUBARs mascot is a POOP EMOJI! Daniel Werbin im not proud in the slighest on how terrible of a warped weld job I made the frame and if we ever as a group do this again I will make sure the next one is the most perfect one I can possibly do. But for now, yeah. at least it rolls Michael Unangst 🙃🤣 https://i.groupme.com/500x313.jpeg.bc6c3ca1002c48a2ba378b723b40154b Rob KA2PBT It was your first major weld job ... and again ...

Karen KD2HII https://i.groupme.com/2656x1494.jpeg.4b3caeb7e97a4e4791784d0583d686f1 Karen KD2HII Instrument panel installed.... reverse gear available..... looking good. Karen KD2HII Tested well tonight, and drove right up to the shop door when done. There was a Fred Flintstone moment when Daniel's shoes peeked out through the plastic car hood - we need a resting spot for them which doesn't interfere with the tie rods or kick out the top. Karen KD2HII @The Cleco Kid , FYI, from Colton Sikkes (8) "that is the COOLEST jeep decorated with bullets. I'm telling my dad to make me one." The Cleco Kid DW, can we cut out the steel pedals and then recess the area where the driver's heel goes? Daniel Werbin Probably yeah. Just as long as your ankles clear the tie rods The Cleco Kid Is there some sort of medical procedure or surgery the drivers can have on their legs so they can fit? KC2WCQ Robert Bunch of small framed drivers in Ft. Ree @The Cleco Kid The Cleco Kid Abbie, with fake ID..... work on the @KC2WCQ Robert KC2WCQ Robert Would you like that vertical or horizontal? The Cleco Kid Come on, if you are going to do it ... Horizontal. What about Spud as a driver? Wait...By then he may weight more then Abbie. KC2WCQ Robert True, does @Kyle Watt have a DL yet? Kyle Watt In progress... KC2WCQ Robert With all that steel it looks like your the crown Vic of the prs series KC2WCQ Robert https://i.groupme.com/492x480.jpeg.cfe7228d8e8e43ea8beae251b16fb13b KC2WCQ Robert https://i.groupme.com/225x225.jpeg.55fec091fd5748ad96f871e6c00ada4c KC2WCQ Robert Don't forget the distractions The Cleco Kid I'm heading over to work on the car body this afternoon. Karen KD2HII What time? I can come, but need to be back home by 5. The Cleco Kid Earliest will be 1630, so it's not worth it for you @Karen KD2HII Karen KD2HII Evening is a possibility, 7:30 onward Karen KD2HII Tomorrow from 3 till whenever Daniel Werbin On Saturday is it possible for us to do a track test? Rob KA2PBT Likely .... Tech? Daniel Werbin Sure why not. Close to @The Cleco Kid The Cleco Kid One side fitted. https://i.groupme.com/1781x1002.jpeg.f07e8a6de5e447809adaa70588346ba7 The Cleco Kid Fun fact, the red fiberglass does not secure to the front or rear body. It's a fixed stand alone. https://i.groupme.com/1781x1002.jpeg.c473f443c1e94a31bc05a3e026c64ea8 The Cleco Kid Stern extender 90% done. https://i.groupme.com/1781x1002.jpeg.3feea201b41b422cb02a31bcbf0101f2 The Cleco Kid One more side shot. https://i.groupme.com/1781x1002.jpeg.370ccb3250504522a71a98f87a8e25c1 The Cleco Kid Inside the filler. https://i.groupme.com/1781x1002.jpeg.86d6188f9c9b454e8beec105d313cb59 The Cleco Kid I'm concerned about the stern bumper sticking out to far. Tom Scarince Yeah if your cut a corner too close you end up coming to a very quick stop Daniel Werbin agreed Karen KD2HII I would favor both shortening it, and also rounding the corners, or at least a 45 degree cut. The Cleco Kid I should add that it only sticks out 3.5 inches from the extender. Daniel Werbin could still very easily get caught and ripped off if you brush sideways against something on the track like a barrier Daniel Werbin even at low speed I hit one last year and a lot of others did too Karen KD2HII @Daniel Werbin , I think we agreed that the most likely collision would be with the track itself, rather than with another vehicle. Some of those cars are held together with spit and bubblegum. Daniel Werbin agreed Karen KD2HII (Though they all look nice) Rob KA2PBT Are we gathering tonight? Daniel Werbin Yes Karen KD2HII Yes. There is still work to be done. Karen KD2HII Was hoping to have a punch list for remaining tasks Rob KA2PBT @Daniel Werbin I hear there is a programming task? Daniel Werbin Yes you need to parse serial data on a USB serial port into a nice display Daniel Werbin Can you do that? Rob KA2PBT Sure why not Daniel Werbin Cool Daniel Werbin Comma separated data Rob KA2PBT even easier Daniel Werbin With a unique start character and a counting frame stamp Rob KA2PBT I think we'll need to deep dive when I see you later Rob KA2PBT https://i.groupme.com/320x320.png.baae3309440247d09ca517b68eda9037 The Cleco Kid We're going to town... Daniel Werbin I'll be an hour Karen KD2HII @Asst Project MGR , we need cribbing The Cleco Kid @Asst Project MGR I need 6 Grade 8 1/4-20 X 1.5 bolts please. Asst Project MGR Hex head? The Cleco Kid Yes.....8-32 steel rod also Tom Scarince @Rob KA2PBT do you remember if you ever found my unibit? To be honest I half remember you giving it back to me at some point. Daniel Werbin What is the current status of everything? Are you ready for me to come over @The Cleco Kid or are you still working on the body? Rob KA2PBT No I did not. I'll look next time in the shop ... but to be honest we spent 10 minutes looking for a spool of solder last night 😳 Tom Scarince That's The Story of My Life. Certainly don't sweat it. Rob KA2PBT Any plans for a road test Asst Project MGR On our way to Home Depot on 57 Asst Project MGR We have graduated from shredding belts to this.......

Where? Rob KA2PBT I'm going to the shop to get my hat The Cleco Kid Last I saw it it was on the handle bars. The Cleco Kid The fiberglass sides of the mid-rail are 3" high, can we put a 721 there? Karen KD2HII Yes Karen KD2HII We have no other adornment or endorsement ad there, so why not? @KC2WCQ Robert , I hope you had a great time in Wildwood.....but we need that vinyl please. Can you? KC2WCQ Robert Will be done by tmr evening Karen KD2HII Will you be installing, or will we? KP and I are at the Evil Genius Lair tomorrow night, and possibly Wed also. KC2WCQ Robert I probably won't have time to get over there but I can get it to you tomorrow Karen KD2HII Okay. Supposed to meet there for 4:30. I can pick up if needed. Devlin M so, Here's what we have to work within for Moxie: Devlin M 4.1.2. Moxie Challenge Each team may perform a 1 minute (or less) sketch using their team members and cars to entertain the crowd. Teams will be voted on by a group of 3 small children randomly selected from the audience, on the old Olympic scale of 0-10. These points will be tallied up and added directly to your score, in the same way the race points are awarded by finishing position. If you want to have a song played during your sketch, it must be tested and submitted ahead of time otherwise the Sanctioning Body won’t play it. Before the Moxie Challenge begins teams will line up along pit row in the order they wish to appear. You may submit, along with your Moxie Board label, answers to a short questionnaire about your team so we can better announce your team information. The sanctioning body will use that info to give the crowd a background of who you are and why you bothered to do this. Devlin M So we need Devlin M a) a skit Devlin M b) 3 bribes for small children. Money, sweets and toys are customary Devlin M We've done the good building part, now we have to do the entertaining asshole part, which I think we could have a fair shot in Devlin M 6.2.2. Moxie Points Moxie is that little extra spice that levels the playing field. Not only can you win race points, but you can also entice and rile up the crowd to win points from them. It will be your team’s job to find ways to garner audience attention and keep it over your competitors. This is the ultimate pursuit of the weird. Giant boom-box cars, Lucha masked racers, pre-race dance party and confetti cannons are all par for the course. Consider this the social engineering section of your exam. Some teams will write this off, but we at PPPRS think you should take heed: this is where real champions are crowned. Underdevelop your car against your rival hackerspace? Easy! Gain those points back by dressing up as a chicken. Your odds to win are good if your goods are odd. Consider it Halloween in July, and you have to get more candy bars than that kid next door. Devlin M Also if you are still reading I’ll give 400 points to anybody who develops an open source 3 phase motor controller. Schematics need to be an open source format. Code has to be commented out and posted on github. Gotta spec out the cost of the parts, release the instructions online and have those ready at the moment of points rewarding. The design has to be proven and race winning. Yep. Totally for real here. Daniel Werbin I didn't develop it but i can provide all of those things lol Devlin M This ruleset hereby deputizes Jeremy Bloyd-Peshkin (or the generic equivalent thereof) with driver and team orientation prior to each PRS event. The guidelines for this orientation involves proper driving etiquette and the basic racing guidelines that turns your new team into one that people will actually like and respect, because you didn’t cut anyone faster than you off and ignore all the rules we wrote here. For example, Avocados are banned. Yup. They are not allowed. If you’re reading this, you’ve read an important part of this rule. So important, that the first sentence to the Sanctioning Body is “I hate avocados.” That way we know you read this, and the other lines in this ruleset. Get it? Good. The Cleco Kid @KC2WCQ Robert @Karen KD2HII the sides can come off for and brought to the Hill for labeling if needed. Devlin M Driver costume idea? https://i.groupme.com/1470x1470.png.653393f35e9b4251b8878fc61f6788c9 The Cleco Kid Where's Andrew P. when we need him? Daniel Werbin Can we use a smoke flare The Cleco Kid My mistake, Andrew Pee... Devlin M I'm sorry, This one https://i.groupme.com/609x897.png.f32ccb095b2d4fa58f98daaa1c44e8f7 Devlin M Its $23 dollars and prime shipping Devlin M crap, Large is $23, small/medium(which is one size) is $39 The Cleco Kid With 3 presents for the judges??? Devlin M exactly Devlin M So i searched for "camo" on party city's website to see what we could get quick, and I have some suggestions Devlin M I think one of these for each judge kid https://i.groupme.com/751x454.png.1b5cf44d76544c698fd044bfa790176c Devlin M And one of these for them too. What child doesn't love a whistle? Then we give some to the crow, blow them ourselves, do what ever to grab attention https://i.groupme.com/807x499.png.b4f73f7ed94d49afaa303ec5a91973df Devlin M and maybe we could all wear these for S&G and give them one too https://i.groupme.com/752x484.png.48a3c930b4864652a750d0c09fdf41d8 Devlin M make them "honorary members" of our team Devlin M maybe rank of General? Devlin M candy and money are nice, but getting to dress up and join the big kids? thats a real treat for a kid Rob KA2PBT https://i.groupme.com/484x433.png.ee95b5d2978042e4b7faac7725d14068 Rob KA2PBT http://fubarlabs.org/wp-content/uploads/2017/09/Reg_Form_2017fixed.pdf Rob KA2PBT Ideal Farm and Garden Center is located in Sussex County Asst Project MGR send it Daniel Werbin We should go there Daniel Werbin Also @Asst Project MGR has the belt company responded Asst Project MGR tomorrow or tuesday waiting on a tracking number Daniel Werbin On a response or actual items arriving here Asst Project MGR items Daniel Werbin Sweet. Did they say why they dropped the ball at all Asst Project MGR nothing Asst Project MGR t the track will be on hard packed dirt, grass, and sand. The racers will be expected to plan accordingly Asst Project MGR unfortunately i will be out of town that weekend. Daniel Werbin That's not the nyc one right? Daniel Werbin Also i feel like dirt will be easier on the car Asst Project MGR thats the sussex one Asst Project MGR maybe on the tires. not on everything else Daniel Werbin Yeah Karen KD2HII https://i.groupme.com/1494x2656.jpeg.86e36cba0ecc4ccfb590efb94d9fc537 Karen KD2HII Strengthening the cart. @The Cleco Kid strikes again.... Daniel Werbin https://i.groupme.com/1920x1920.jpeg.4812c26ff22d45c3ae810317108d8cb3 Daniel Werbin Look what we just got a spare of Asst Project MGR we need to write them a note thanking them Rob KA2PBT we need to put their name on the car Daniel Werbin Yeah Daniel Werbin http://www.enertionboards.com/ Daniel Werbin This is them. If you can make a thing for the car that would be cool William Browder-Little Stickers compliments of Roberto https://i.groupme.com/2024x1518.jpeg.8c849c72217f44029d73a06597f77cf6 Daniel Werbin Sweet Rob KA2PBT https://i.groupme.com/1125x1500.jpeg.66905ff7811b44e9b001a9e8396f002f Asst Project MGR ooohhhh shinny Rob KA2PBT And smelly Karen KD2HII And covered in some kind of slime...... Michael Unangst https://media3.giphy.com/media/V6fjQcEne91Go/giphy.gif Michael Unangst I'll donate a set of tires we can throw em on after racing is done and see if it'll smoke em😎 Rob KA2PBT hey can we meet at the shop Thursday at 1900 or before?? Rob KA2PBT I talking to Abbie's Dad The Cleco Kid I'm planing on going after work. Rob KA2PBT I have BOE tomorrow so .... Karen KD2HII I'm there Thursday also. GroupMe Rob KA2PBT added Andy to the group. Daniel Werbin i cant unfortunately Karen KD2HII It's okay Dan... we got this. Now its on to logistics of getting it all there.That's why it's a team effort. Hope all is going well for you in Georgia. Daniel Werbin just let me know where i need to be and when. ill have batteries charged and my tools and spare parts I have all packed. i tried to toss spare parts for stuff onto the cart when i was last in the shop Karen KD2HII I imagine we may go through our paces on Thursday, and consult you at that time. Devlin M The race schedules are up on Facebook. 10:30 quals, 12 moxie, 1 Sprint #1, 3 Sprint #2, 5 Sprint#3, on Sunday, 10:30 autonomous, 11:30 Sprint #4, 3:30 Sprint #5, 3:30 Endurance Devlin M I think we are going to need as many batteries and charger as we can get our hands on Michael Unangst @Daniel Werbin how have the 12V ones been for the controls? I can prolly come up with a couple more if needed Asst Project MGR @Devlin M is each sprint 45 laps? Devlin M I'm not sure. The rules and last year only have 2 sprints, one 30 and the other 45. I don't know what the plan for 5 of them are Devlin M Apparently Make wanted more racing Daniel Werbin 12v is fine i think Devlin M There is also FUBAR Lab's first maker Fest in Sussex on oct 21 with a race, if we want to register Daniel Werbin So is there a 2 hour gap between sprints Asst Project MGR less considering a race may be 45 laps and the start times are staggered by 2 hrs Daniel Werbin I might try to cram 2 sets of batteries into the car. I'm worried if there is 45 laps Devlin M There will most likely be at least one match that is at least 45 laps Daniel Werbin We can recharge each pack in 30 mins Daniel Werbin The issue is i don't think we can pit during the sprints Rob KA2PBT Based on this weekend I think we can do 45 laps on a pack Devlin M They only posted the times 3 hours ago and haven't posted any more info yet. I'm watching everyone ask the same questions we are having Daniel Werbin You think so? How short are the laps Rob KA2PBT No worse than our test course Daniel Werbin I guess we will see and alter strategy as we go Daniel Werbin If anyone has an rc grade charger for 6s lipos, bring it Daniel Werbin I have a big dual charger Asst Project MGR https://youtu.be/OpQTEDXv11c Asst Project MGR I will bring some of the 400W 24VDC supplies Daniel Werbin I have an ac supply for it but an extra won't hurt Asst Project MGR was that video of Sat or Sunday last year? Devlin M https://i.groupme.com/1920x1080.png.c1697c8bf5dc4dda800265066c1e6648 Devlin M Do we have an itemized budget yet? Rob KA2PBT We can look at last years and adjust for this year .... should be no major cost changes .... I think the total add the the vehicle was just the ardunio and display .... also an upgrade to motor and batteries Rob KA2PBT right@Daniel Werbin ? Devlin M ok, as long as we can prove we are under $500, not including safety mechanisms Devlin M Has anyone been looking at the rules while building, or should I go over requirements with everyone now? Rob KA2PBT any significant changes? Daniel Werbin I'll toss up a vague item list but i think honestly nobody cares as long as you aren't significantly faster then anyone else Daniel Werbin And we aren't Devlin M I don't belive so. Major requirements are on budget, bumpers, batteries, fuses, kill switch, and team number Daniel Werbin Nobody even checked it last year Daniel Werbin We still follow all those things i think Devlin M I thought we did have a vageu inspection last year? Daniel Werbin Yeah but we blew the budget last year too and during inspection nobody asked for a list Devlin M Since the car has been repainted, do we have our team number visible and at least 1.5" high? Daniel Werbin They have stickers for the body i think Devlin M The itemized budget is only highly recommended, and would only be used in cases where the judges or other teams have a suspicion that we went over budget. Asst Project MGR in the unlikely event we get asked hand them last years and move on Asst Project MGR team numbers are covered Devlin M great! Devlin M then we should be good Devlin M Anyone who has even daydreamed about driving must wear closed toe shoes, abrasion-resistant gloves, long pants and a long shirt. Bring your own safety glasses, and I've been told@The Cleco Kid  will be covering the helmets Devlin M also, in order to drive in a race, each driver must have driven a practice lap, so make sure you get there early and get in the car Daniel Werbin Sounds good. I normally do all that anyway. I'll just wear long sleeves Devlin M how many possible drivers do we have? On endurance races, the driver must either change, or change costume every 15 mins, so the more the better Rob KA2PBT Incidentally, for MOXIE, recommend@The Cleco Kid in the camo morf suit doing interpretive dance with American flags. Devlin M If we want a costume, now would be the time to decide that so we can get it shipped in time Daniel Werbin They need to weigh 190 or less Daniel Werbin More then that blows the belts Rob KA2PBT allegedly Daniel Werbin Hey can we get a comical maximum load capacity sticker The Cleco Kid #FF2X4 Asst Project MGR @Rob KA2PBT dont bring anthony into this Asst Project MGR I will supply a second charger Daniel Werbin Okay. How many watts? Asst Project MGR enough Daniel Werbin 50 or 200 Daniel Werbin Ok cool Daniel Werbin That one is fine. So we have two changers Daniel Werbin Chargers* Daniel Werbin Each battery is made of two packs. My dual charger can charge 2 packs at once in 30 mins. Nick's is the same, so that means the team can charge 4 packs in 30 mins Daniel Werbin Or two sets of running batteries Daniel Werbin Which means we are self sustaining because it takes 15 mins to drain a pack at maximum attack and we can charge them as fast as we use them The Cleco Kid Does this involve math? Daniel Werbin Make sure we bring extension cords and power strips Asst Project MGR thats just how we roll. Karen KD2HII (.....not any math that you're ever going to use...) Asst Project MGR @Kyle Watt are you set for Friday? Asst Project MGR @Daniel Werbin has some requests for "claiming" our space in the pits. You two work it out please Kyle Watt Yes. What time should i arrive by? Daniel Werbin My request is you take a picture of you claiming it just in case Asst Project MGR i think later afternoon should be fine kyle Kyle Watt 3? Daniel Werbin I don't know the times but that sounds fine Troy Godfrey anyone at the shop?

Cart tool side storage installed, remaining metric wrenches painted green, 6. Taint touch ups done, (and probably a few other things that I didn't see). Nice job guys! Daniel Werbin Looks great Daniel Werbin Did the rear bumper get trimmed too? Daniel Werbin also any pictures of the final look? I want to see the vinyl! Karen KD2HII I will be sure to post tomorrow for you. Karen KD2HII And yes, @Daniel Werbin , Kevin shortened the rear bumper previously, and Abbie and Andy trimmed the insert strip for it.

Will the helmets have face shields? Or are any of the small face safety glasses around still? Daniel Werbin We could consider food. Food is damn expensive Daniel Werbin If we have a big cooler like the test session it would make sense Daniel Werbin Can stick it under the pit table Asst Project MGR there will be a truck based cooler and I believe we have a new trojan cooler The Cleco Kid @Devlin M Shawna gave me 2 helmets, both full face, 1 with a shield. I have the cooler backpack. The Cleco Kid There is another full face coming too. Daniel Werbin Sweet Daniel Werbin So yeah packing food could be a good idea The Cleco Kid There will also be trips to the truck as needed, where the main cooler will be. Daniel Werbin Sweet Devlin M Will the 721 flag be coming? Karen KD2HII Not certain of the whereabouts of that. I don't believe we had it for FD. Kyle Watt Eta 1 hr, got a late start.

Karen KD2HII In the center of Hope? I thought we 'd do the Hope Park & Ride, but I suppose we can come get you wherever you feel comfortable parking your car for the day. Daniel Werbin I was told to come here by Nick Karen KD2HII Well, he's the one driving so..... Daniel Werbin No panther valley Karen KD2HII Ahhhh, at exit 19... gotcha...

The Subway straight up got stuck for a while. Ben Boniface Welcome to NY mass transit Karen KD2HII https://i.groupme.com/1494x2656.jpeg.550c801c5f374c25ac09b76391ddbd7e Karen KD2HII In the firat race, of 30 laps, We came in 11th out of a field of 20. There was a flat tire on the very last lap, but Dan brought it in past the finish line. There was some wear on at least one other tire, and the shafts collar wasn't happy, but a very creditable performance overall. Michael Unangst https://ih1.redbubble.net/image.350474955.5577/st%2Csmall%2C215x235-pad%2C210x230%2Cf8f8f8.lite-1.jpg Kyle Watt No fan has been found. Kyle Watt I have looked and asked nearly everyone. Karen KD2HII It's okay, Dan has a connection and the possibility of assistance Karen KD2HII The folks who made our motor are here and are out looking too. Now *that's* customer service. Rob KA2PBT I'm 2.2 miles away from a harbor freight.... I'll get tires later and report back Karen KD2HII https://i.groupme.com/1494x2656.jpeg.e780fc2ae9034cc7ab751d474fb886fe Karen KD2HII This was the fix for the shafts collar... a cotter pin. The Cleco Kid https://i.groupme.com/1781x1002.jpeg.21c36ad3edec46e195e7f4503da8992f Rob KA2PBT Okay .... anything else??? The Cleco Kid No, that's it.

Good night. Daniel Werbin night everyone Evan Markowitz Have a good night, good job today guys Kyle Watt Njit did, eventually, make it home in mostly one piece. Evan Markowitz I was a bumbling idiot (more than usual) just from exhaustion Evan Markowitz I walked almost 11 miles today apparently Karen KD2HII In conclusion, Blairstown made it home okay also The Cleco Kid And drove 5 laps. @Evan Markowitz Evan Markowitz On my way back Evan Markowitz Anyone else here yet? Tucker KD2JPM @The Cleco Kid Or @Troy Godfrey i accidentally grabbed this with my stuff last night.

Tucker KD2JPM I will be home for a good part of the day today if you want to pick it up. But will he leaving later The Cleco Kid When ever I see you next is fine. Daniel Werbin @The Cleco Kid let me know when you want to meet up to unload the kart at the shop The Cleco Kid Yes, let's say 1600 as a time to start with. What other times can people be there. Daniel Werbin Sounds fine to me Karen KD2HII Coffee and A/C right now.... wilting.... Evan Markowitz I'm out at the Maker lounge trying to not dehydrate lol The Cleco Kid DW, can we make it 1500?

The Cleco Kid 6:15:00 Kyle Watt I thought him dancing with the inflatable thing right after was much more entertaining. Karen KD2HII Timestamp for that one, please? This belongs in the media program for this year's banquet, which is now officially open for discussion (because we accidentally skipped it last year, LOL!) Kyle Watt Starts at around 16:16:45 Karen KD2HII Hear ye, hear ye!!...PRS Racing may be dormant at the moment, however finances dictate that we request any receipts for expenditures to be turned in for reimbursement in the very near future. Please submit via email or PM to me prior to our October 19th meeting so that we may have a full understanding of our expenditures. We will continue to do fundraising as a group to defray costs and reimburse. Thank you! Karen KD2HII kbartlettlance@gmail.com. Many thanks for your support during our racing season. Rob KA2PBT @Daniel Werbin What display did you use on the car? Daniel Werbin RA8875 based TFT 800x480 5" from adafruit, arduino mega Rob KA2PBT It's a touch screen? Daniel Werbin It can be Rob KA2PBT OK. Will keep that in mind Rob KA2PBT I have big plans ... BIG ... BIG... BIG!!! Asst Project MGR i just want it to keep rolling, DanPBTO Daniel Werbin What are these plans Rob KA2PBT Not sure yet ... but they're BIG! Daniel Werbin Do keep us updated Rob KA2PBT I'm going to get one of those displays so I can experiment Rob KA2PBT also ..... I think there's an "autonomous" competition Daniel Werbin that autonomous competition gets expensive Rob KA2PBT define expensive Michael Unangst http://ep.yimg.com/ay/yhst-80707182936312/it-s-gonna-be-yuge-trump-tee-2.jpg Daniel Werbin lidar Rob KA2PBT I'm sure we could hack something out ... laser pointers cheap Daniel Werbin yeah thats not easy lol Daniel Werbin I've looked into making lidar Daniel Werbin the best approach is to use a spinning lidar-lite v3 Daniel Werbin but then we have to learn all the machine vision and slam alglorithms and its so far beyond me. but I do really want to learn them Rob KA2PBT http://a.co/eXWVMIu Daniel Werbin the main issue is its outdoors Daniel Werbin all the cheap well used stuff like kinect only works indoors Rob KA2PBT Think of the "problem space" ... I don't want to drive on Route 80 .... It's a well defined course with big barriers around it .... ultrasonic radar "might" be sufficent for the task. Asst Project MGR new rule. the race car has to finish a race series before we furry little feature creep our way to a new series of problems Tucker KD2JPM Don't have to worry about opponents if there are no opponents https://i.groupme.com/626x373.jpeg.4da248098fff4bd48e1d8a4691c63230 Rob KA2PBT as@Devlin M would say: fair enough. Rob KA2PBT I think we need a bigger motor(s) Asst Project MGR we are pretty #$%^& close to a solid car.  Lets nail the basics with a few months left to work on the stretch goal before next year Daniel Werbin yeah we are very close Daniel Werbin just need more cooling Rob KA2PBT Agree ... reliability could be a wining advantage ..... until we had catastrophic failure we were the most consistent performer on the track. Rob KA2PBT (I've been watching the MAKER FAIRE produced videos) Rob KA2PBT Multiple cars had multiple failures The Cleco Kid https://i.groupme.com/550x552.jpeg.d5e2d23f0c8d449bbe0af487083b8721 Tucker KD2JPM The Clash? The Cleco Kid What, the song? Tucker KD2JPM Yeah Tucker KD2JPM Nevermind, I was thinking of I Fought the Law The Cleco Kid https://youtu.be/L397TWLwrUU Tucker KD2JPM That's by the Clash Tucker KD2JPM I remember now that it is Judas Priest, just listened to it the other day The Cleco Kid I listen to it every day. Tucker KD2JPM Doesn't get old? Tucker KD2JPM I try to listen to something new often The Cleco Kid Can somebody explain the BTL BTL car to @Tucker KD2JPM . TU. Gavin @Daniel Werbin try cheap Chinese lidar is more problemsome than it's worth Daniel Werbin Probably Asst Project MGR there was some unit being refered to in the PRS promo video. need to investigate. The Cleco Kid I have proposed this idea to the 721 racing team. We build a car soooo illegal that if forces inspections of all the teams. After 1/2 of the teams are disqualified, we just race the 721 card. The name of this throw away car will be Breaking The Law- Breaking The Law. Daniel Werbin i still wish we could make it work, too. GroupMe The Cleco Kid changed name to The President of Making The President of Making The BTL-BTL doesn't even have to run, I figure it ability to hurl pig manure into the crowd enough. Daniel Werbin can we make it run though. just grossly overpowered Daniel Werbin twin 24v truck starter motor drives Michael Unangst burnouts for days Daniel Werbin I want to do a donut on the start finish line Asst Project MGR better get some hoosiers, cause the HF tires aint up to that Daniel Werbin I want the thing that makes them go 'we should inspect them' be our qualifying or moxie round where we do a massive burnout wheelie Asst Project MGR sorry@Kyle Watt you will still have to get hit in the nuts Daniel Werbin the car doesn't have to last long, just long enough to piss them all off Daniel Werbin I want them to initiate the inspection. I dont want to call them all over because you saw, they didn't even look at the cars The President of Making Technically each team gets a nut. Daniel Werbin I found our motor Daniel Werbin http://www.bluebird-electric.net/aircraft_carriers/aircraft_carriers_pictures/Queen-Elizabeth-AIM-20MW-Electric-Propulsion-Motor-Aircraft-Carriers.jpg The President of Making That Motor has for 4 75HP motors right on it for cooling. Daniel Werbin thats what our car needed this year Daniel Werbin i wonder if we can use that as an excuse to get more power. "oh those aren't drive motors.. they are cooling motors." The President of Making I'd say your right Poindexter. Daniel Werbin "that big battery pack is just a cooling pack." Daniel Werbin but in seriousness, what can everyone think of in terms of cheap, high power DC motors? brushless is great and all but too expensive for a throwaway cart Daniel Werbin my first instinct is starter motors Asst Project MGR perhaps we need an ethanol based cooling system for the car, drivers, and pit crew. Just saying The President of Making https://youtu.be/0ZG11UBoj-o The President of Making Form this point on it's Breakin the Law- Breakin the Law. Evan Markowitz Lol I love the title Tom Scarince did someone say dc? Tom Scarince https://www.grainger.com/product/DAYTON-DC-Mtr-3XE19 Daniel Werbin thats a tiny motor Tom Scarince https://www.grainger.com/product/PRESTOLITE-MOTORS-DC-Motor-5JJN9 Daniel Werbin that has me thinking actually. hey everyone in FIRST, can we use like 10 CIM motors at the same time Daniel Werbin overvolted, naturally Michael Unangst https://youtu.be/lkPlqzZSSH0 Michael Unangst search "Zombie 222" on youtube. that's the name of the car. thing is nuts😂 Michael Unangst two dc motors coupled together....at full throttle 1.4MW of power. 369VDC nominal at like 3800amps Daniel Werbin that sounds like what we need Rob KA2PBT Thinking this could be scaled down and adapted https://en.wikipedia.org/wiki/Nuclear_marine_propulsion Rob KA2PBT Maybe next year we can find some $10 tires Tucker KD2JPM Twice the price, twice the quality? Hopefully Asst Project MGR https://youtu.be/HIhfwjWuj-I Asst Project MGR http://www.hfqpdb.com/best_coupon/10%22+PNEUMATIC+TIRE+HaulMaster Rob KA2PBT Maybe if we set 'me up as dualies they'll last twice as long Daniel Werbin https://i.pinimg.com/originals/52/05/87/520587ca563a989309d1cf2a562c4d15.jpg Daniel Werbin if we have a differential or something like that, the tires would easily last multiple races Rob KA2PBT http://www.instructables.com/id/Mini-Electric-GoKart/ Rob KA2PBT posting just 'cuz you never know ... there could be a useful idea there Karen KD2HII HELLO racing fans! The date has finally been announced, and we will be earning $500 to pick up roadside garbage in Blairstown. We need at least 6 people, names in advance, to commit for Saturday, Nov 18th.

Karen KD2HII @Tucker KD2JPM , @Abbie , @Daniel Werbin , @Devlin M ... there is no truth to the rumor that a pizza incentive (read that "BRIBE") may be involved.... except... why not? Come and help - we need you! Kyle Watt If rides are involved, i should (barring unforeseen major projects around this time) be able to assist.

Will update in the future when more information is available Rob KA2PBT WOW!!

(Tomfoolery optional) Daniel Werbin I might still be in Canada Rob KA2PBT Are you in Canada now? Daniel Werbin About to be. For procomm Rob KA2PBT What makes you think they'll let you back in if you leave.

We will meet at my house on Saturday at 10, complete our work in about an hour or so, then reconnoiter to one of Blairstown's fine establishments for pizza and fraternization. Karen KD2HII Say you will, Power Racing fans! @Rob KA2PBT has even offered Friday evening transport home for those of you at NJIT. How's about THAT?

The President of Making Just put a box over it, and it's race time. Troy Godfrey Thought that these were small toys. I saw one full size in shop rite. Is this the same one. Rob KA2PBT That’s were I snapped the pic Troy Godfrey kinda like the look of this one -- reminds me of the batmobile from batman begins https://i.groupme.com/524x436.jpeg.19cf1a5db8f8496b8ba43c066e3ac738 Troy Godfrey https://i.groupme.com/525x508.jpeg.fe0b61a309374ea7a51aadbaa9613d70 Rob KA2PBT https://i.groupme.com/1024x768.jpeg.070b818053724b9980cabab579292ad2 Devlin M Is that on Toys r us clearance sale by any chance? Evan Markowitz I didn't even think of this Rob KA2PBT Why yes .... yes it is .... but only 10% right now Devlin M They are keeping the hundred or so big profit stores open, but I doubt the pburg store is one of those Rob KA2PBT I heard this week they were all going Devlin M KB toys is trying for a comeback Rob KA2PBT I don’t see how Daniel Werbin starting up this chat again, for i have updates. my friend who plasma cut the parts for us that one time says he has the ability to get stuff cnc plasma cut, cnc laser cut, and cnc milled.  and because of the large time we have, the price can go way down and or free because it can be snuck in with other jobs on leftover spots on the sheets of steel (for the laser and plasma cutting things)   I fully intend to use this to make the car better Daniel Werbin https://i.groupme.com/3500x1904.jpeg.3561f2f00d1e49eeb8683597429e10d9 Daniel Werbin https://i.groupme.com/3500x1904.jpeg.ef33d949b59245b38e3589c85017493a Daniel Werbin https://i.groupme.com/3500x1904.jpeg.d346ee1e69af4a8396b4510357d0d65c Rob KA2PBT Chain? Daniel Werbin This motor pod will articulate on that bushing and a mountain bike rear shock so instead of bouncing and tripoding all over the place, it should keep the power planted. And okay,@Rob KA2PBT after all these years, you were right.  rear brakes are better, but only in this instance because 95% of the weight is on the rear tires. Daniel Werbin and yeah, chain because it seems much, much easier to obtain Rob KA2PBT Literally tearing up right now .... Daniel Werbin the motor controller company that sent us controllers last year is sending us a prototype dual motor controller with even more power per channel then the old one had period. so dual motors this year! Michael Unangst more motors...more betterer Daniel Werbin our issue last year is the motor heated up to about 200C and then softened the glue holding the magnets on, so when we got rear ended they came apart and ground the stater up Daniel Werbin which shorted the windings, and blew the controller, which spent the entire race session thermal throttled to 30% power because, overheating Daniel Werbin so this year everything is water cooled Michael Unangst arcy sparky magic smokey Tucker KD2JPM If we put spikes on the rear bumper nobody will rear end us Daniel Werbin that might go against the rules but who cares Daniel Werbin spikes inside a pillow Daniel Werbin the spikes are just poorly shaped support rails Michael Unangst or a flame thrower, they only need to see it test fire once Rob KA2PBT If we shoot bananas out the back we could get moxie points Daniel Werbin my other idea was to make a gas engine themed car that's actually gas powered but nobody realizes it and thinks the noise and smoke is part of the theme Tucker KD2JPM I can work on something to do that Tucker KD2JPM The banana thing Daniel Werbin https://i.groupme.com/3500x1904.jpeg.337fb24bb5eb4c3c83f6e340a13203d0 Daniel Werbin that's what it looks like on the frame Daniel Werbin will have a couple of inches of suspension travel. should help a lot Daniel Werbin if my friend can secure laser cutting services, I might actually design front suspension too Daniel Werbin because why not? Tucker KD2JPM Anything in the rule book against pulse jets?

That paella was worth the trip alone. Evan Markowitz May I be Kyle's +1? Asst Project MGR we may need to be a little more dominant in staking out a space this year. Your note was torn off and we had to jostle for space last year. Daniel Werbin Or we bring our own Easy up like the team next to us did Rob KA2PBT Lets tie@Evan Markowitz to the table Kyle Watt With more than a day's notice I can plan plenty of ways to ensure the table stays ours. Evan Markowitz Hey I'm not the smallest anymore this is no fair 😂 Rob KA2PBT Who’s the smallest??? I would caution how you answer that because if this going where I think it is she’ll kick your ass mighty handedly Tucker KD2JPM I don’t think you should assume @The President of Making ‘s gender Evan Markowitz @Rob KA2PBT That's my point! She's much more capable of defending the table than I. Kyle Watt Shouldn't you be paying attention to calc right now? Evan Markowitz It's recitation, I'm doing just fine � 93 on my last exam! William Browder-Little I'm planning to buy a new ez-up sometime soon due to my outdoor work continuously being stopped by rain. We could be Those Guys(™) and use that plus the three folding tables I have (two full size, one half pint) GroupMe The President of Making added Jackie Farkus to the group. The President of Making @Jackie Farkus is a team 219 alumnus. She goes to NJIT where she is studying mechanical engineering and enjoys fabricating. Outside of being the nicest person to ever come from Oxford, Jackie knows her way around a Taco. 🌮. Please welcome her. Daniel Werbin Hello! Evan Markowitz Hello from GITC! Jackie Farkus Hello!

It's usually much more Asst Project MGR we should use many less tires this year with the new suspension and geometry. Daniel Werbin we have many members in the group =) Asst Project MGR however we need the hubs that we used to throw away Daniel Werbin also, don't go too crazy tire purchasing because while the new geometry will significantly lessen the wear on the tires, the cart will also be significantly faster Daniel Werbin so it might balance out, but I don't know for sure until we test Rob KA2PBT well I'll grab 4 now and keep an eye out for more coupons Daniel Werbin sounds good to me Tom Scarince Need to spend some quality time on some go-kart forums The President of Making https://i.groupme.com/1920x1080.png.6ddd59aa58314bf4bf0c830f907fba15 Rob KA2PBT I can't decide ... is the the look of excitement or terror .... ??? Kyle Watt I think that's the 721 motto Daniel Werbin If the car goes half as fast as I wanted to this year it will definitely be Terror Rob KA2PBT "I'm pretty sure my last words will be ... Huh, well that didn't work" Evan Markowitz Can we stream a GoPro feed from the car? 😂 Daniel Werbin Yes please Evan Markowitz I'll get to work. Daniel Werbin Would be cool to have in a tv in the pits Rob KA2PBT Literally ... the hardest problem is cell network congestion Evan Markowitz Do you have any spare TX/RX pairs from a drone? Rob KA2PBT Oh that's a win Evan Markowitz Because I don't wanna do that bonded cellular lol Daniel Werbin Many, but all are 720x480 non hd Evan Markowitz 720x480 still better than 0x0 Daniel Werbin Very true Daniel Werbin Though we could also use ubiquiti stuff if it's laying around and go 1080 over ip Daniel Werbin WiFi congestion over makerfaire is likely very low Evan Markowitz That's real directional though, we're in a moving vehicle Asst Project MGR omni 2.4 on the pit pole Asst Project MGR i have a gimbal we can use for the go pro. what will be the digitizer? Daniel Werbin Not sure. Hdmi to ip thing probably Asst Project MGR we need someone who isnt me or dan to own this part of the project Evan Markowitz Rent a teradek? Daniel Werbin Please Evan Markowitz I don't have any hardware spare for that unfortunately :( Daniel Werbin Oh I'll lend hardware if i have it Rob KA2PBT don't over think this ... I'm thinking the drone POV on 1.2 or 2.4 gig NON-IP is the best idea Daniel Werbin Yeah and i have piles of it Evan Markowitz I'm thinking the same about now, if we wanna get fancy we can deal with that in the pit Daniel Werbin I already have a drone ground station in a pelican case set to receive the same telemetry signal the cart uses now and 1.2ghz video Asst Project MGR well duh Evan Markowitz You're a beautiful person Daniel Werbin https://i.groupme.com/2016x1512.jpeg.5755671c21b74ffd8b5039c686eb9174 Daniel Werbin Mini itx quad core inside, just needs 10-14v input via powerpole Evan Markowitz That's fucking awesome. Evan Markowitz I'm working on some portable video production stuff and this kind of setup looks like it could be really useful for that even Daniel Werbin Yeah it has a big storage bin under that holds the controller and antenna tracker and cables and stuff, it would be useful for production Evan Markowitz Oooo Evan Markowitz This could work quite well...

All Hands needed. The President of Making I gave Jimmy the shock absorber, he is working an idea where a spring can go on the 3/8" ish shaft. Daniel Werbin i was on mcmaster and i found some springs that would fit that range from 1/10th the force of the current one to 1/5th Daniel Werbin and only around 9 bucks The President of Making McMaster numbers please. Asst Project MGR https://www.leespring.com/compression_spec.asp?springType=C&subType=H&forWhat=Search Daniel Werbin @Asst Project MGR thats probably the better way Asst Project MGR It appears the brake hose is std 10mm fittings Daniel Werbin Nice. Makes things easier Asst Project MGR we might convert to hard pipe along the frame and adapt back to existing hoses Daniel Werbin Sounds fine with me Asst Project MGR https://www.wilwood.com/mastercylinders/MasterCylinderList?group=Handlebar%20Master%20Cylinder Daniel Werbin I like the long handle one that looks sweet Asst Project MGR get a part number off the caliper so we can see what volume each one needs William Browder-Little @The President of Making Dan and I are going to be working on turning the garage into a safe welding space. At some point it would be great to get some assistance with running 240V from the shop to the garage for this purpose. William Browder-Little I'm thinking it'll allow us to not be affected by weather while we're putting the cart together.

He took it all apart, and is now working a spring inside the cyclinder angle. Asst Project MGR in consultation with the ME at work, we think that spring rate is appropriate The President of Making @ 1200? Asst Project MGR yes Asst Project MGR 50lbs / mm Asst Project MGR ish The President of Making Ok, we have to do inspections on them. We didn't cause the crack that we found.

That became somewhere around $250 due to taxes, shipping and handling - still okay, but Rob needs to know the amount to pay before he takes action. Also, we will need to do another fundraiser, but wanted to see a sample budget before we go hog wild spending. If you are moving along with design and parts desired, we are all enjoying the sharing of it. Daniel Werbin yeah, im putting together a spreadsheet on google docs now Daniel Werbin should be ready soon Tucker KD2JPM @Daniel Werbin What extension do you use for physics in sketchup Daniel Werbin msphysics GroupMe Jimmy P. has joined the group Jeanmarie Murray @Rob KA2PBT , I’ve seen those tires! Glad I don’t have them. I would fall off the mountain. Jimmy P. . Zoom..Zoom.. 38 days till World Maker Faire Daniel Werbin @Asst Project MGR @The President of Making © This is the type and style of blueprints I am making for people making parts for the kart, am I missing anything before I do the rest? Daniel Werbin Shared a document: https://s.groupme.com/l600gbbL Daniel Werbin this is not the final blueprint, but just a wip to make sure I'm doing what everyone wants Ben Boniface Not sure who the drawings are going to but specific tolerances may be important Daniel Werbin okay, and as far as i know its just going amonst ourselves, whoever has access to a lathe Daniel Werbin Shared a document: https://s.groupme.com/2kajW2D Daniel Werbin is this better@Ben Boniface ? Ben Boniface Yeah, just one more question, I don't know the specs o. The bearing, but is it possible for either side of those tolerances to result in the bearing not fitting Ben Boniface Like if it's on the oversized side would the bearing not fit Daniel Werbin https://www.mcmaster.com/#6381k351/=1e86fk3 Daniel Werbin I'm guessing you are right Ben Boniface I just know some machinests that like to bust balls about things like that and they make a part they know won't fit Daniel Werbin given that bearing, what would you write for tolerances on the tube so it fits inside? Daniel Werbin the outside of the bearing is the part that contacts the moving assembly so I might just leave it like this and solve any fit issue with a trip into the freezer for this part to shrink it a bit Ben Boniface That would probably be fine with those tolerances and yeah the tolerances of the moving assembly will be more important Ben Boniface If the guy who machines it meets the tolerances you set, heating the bearing and freezing the part will easily get you what your looking for Daniel Werbin sweet, thank you for the advice Ben Boniface What part of the car is this for? Ben Boniface Never mind title blocks are useful Troy Godfrey At the Pocono Raceway. https://v.groupme.com/22123015/2018-08-19T21:33:20Z/471382ce.568x320r.mp4 https://v.groupme.com/22123015/2018-08-19T21:33:20Z/471382ce.568x320r.mp4 Daniel Werbin does anyone here have any experience working with normal hardened steel drive shafts on a lathe? Daniel Werbin I'm trying to figure out what the shaft spindles will be made out of Ben Boniface Hardened steel will cost a nice bit of money to machine, not impossible just not easy Daniel Werbin I was thinking of 4130, which seems to be advertised as easy to weld, easy to machine, and is decently strong? Tucker KD2JPM That was a hell of a crash at pocono @Troy Godfrey it’s already on the news Daniel Werbin i think I might be overthinking all of this, and the whole thing should just be made out of low carbon steel for the sake of weldability and not mixing steel types. it is only a gokart, not a spaceship Ben Boniface Let's just make the whole thing out of titanium Karen KD2HII Thank you for that admission @Daniel Werbin . Simpler is generally better. Fast is good.... doesn't heat up too much is good..... Ben Boniface But what's the part and what's the force on it? Daniel Werbin a 3" spindle axle thing that the rear wheel rides on Ben Boniface 3" of steel supported in two spots? I think that'll be fine Daniel Werbin https://i.groupme.com/1073x769.png.dc7fb2c988144491a00727fa9cca19b1 Ben Boniface 3 inches may even be excessive to be honest I'd have to do the math Daniel Werbin 3" of length, its 1" dia that necks down to 5/8" Ben Boniface OK gotcha that makes much more sense, is the 3" the overall length or the unsupported length? Daniel Werbin yes, but I just rechecked and its actually around 3.75 unsupported Daniel Werbin not counting the threaded area since no side load would be put there, only tension, the furthest bearing sits on the edge where it transitions and thats at 3.75 Ben Boniface Are there any plans to work on the car this weekend I'll actually be up that way then Daniel Werbin none yet I think, we are mainly trying to get the parts made first Daniel Werbin but maybe, to start stripping it down, we'll have to figure it out with everyone else Ben Boniface Gotcha, let me know if you end up with plans to work on it Daniel Werbin but my main question for you is, would making the whole thing out of low carbon steel work in your mind? I've designed the parts to be pretty beefy Daniel Werbin and having everything be the same kind of steel would make welding it a lot easier Ben Boniface That's why I'm asking I would like to talk more about it, and how exactly it's being used, but my initial guess would be yes Daniel Werbin last year low carbon steel worked for everything so I'm not sure why I'm worried about this year Ben Boniface 4 inches of 1 inch steel is very difficult to deform and take a tremendous amount of force to deform Daniel Werbin more then a 80lb gokart with a 200lb person on it can likely create Ben Boniface Well a very basic calculation shows that 1,000 lb load would cause a deflection of less than 0.01 inches Daniel Werbin and we have it across 4 wheels.. so we are probably good Ben Boniface Yeah definitely Rob KA2PBT @Daniel Werbin Post the specs on the radio modules we’re using The President of Making © I was in the shop today starting the ripdown. May be looking for a painter this weekend. Daniel Werbin @Rob KA2PBT https://www.adafruit.com/product/3070 Rob KA2PBT Those are the devices we have now? Daniel Werbin No the ones we are going to get. Do you want what we have now? Rob KA2PBT Yes .... want to see if we can avoid buying new ones .... but after extensive research they would have been my pick Daniel Werbin http://ardupilot.org/copter/docs/common-3dr-radio-advanced-configuration-and-technical-information.html Daniel Werbin V2 Rob KA2PBT According to this ... all you need to do is set MAVLINK to zero to turn off framing Daniel Werbin Yeah tried that didn't do crap. Still no way to tell the system when you are done transmitting so it still cuts off things Rob KA2PBT I’m reading the firmware Daniel Werbin If you find anything let me know that would be pretty awesome Rob KA2PBT Are you doing RTS/CTS flow control on the arduino? Daniel Werbin No Rob KA2PBT That could be an issue Daniel Werbin It could be, does the firmware use that to time transmits? Rob KA2PBT Yes. It does a lot of buffering because the airspeed doesn’t necessarily match the serial speed Rob KA2PBT Can I pick up those radios to do some testing on them? Daniel Werbin sure Rob KA2PBT Tonight? Rob KA2PBT I can come to you Daniel Werbin yeah that sounds fine Rob KA2PBT Time estimate? Rob KA2PBT I can’t be there before 1900 Daniel Werbin fine by me Rob KA2PBT I’ll keep you informed The President of Making © @Daniel Werbin do we have a set of open end wrenches? Rob KA2PBT https://i.groupme.com/1024x768.png.eb29b9a8cfa841bd8e0e1674380be51f Rob KA2PBT well ...it's a start .... Daniel Werbin We have some i think that are on the cart Daniel Werbin looking great@Rob KA2PBT Daniel Werbin love the very optimistic speedometer Daniel Werbin I assume the dead space under the gauge is gonna be a digital readout, right? that would be awesome William Browder-Little @Daniel Werbin @The President of Making © I keep a full set (still complete!) Of open end wrenches in a blue metal toolbox. Dan, it's next to the table that had the delta printer on it. William Browder-Little Has* Daniel Werbin Sweet, that can be the backup option. I think we have a set of them dedicated to the kart that are painted but i can't remember. I know we have sockets dedicated. Can't remember if we also have open ended wrenches too Karen KD2HII Metric is yellow and standard is green, no? Daniel Werbin correct, thats what i recall too Daniel Werbin I assembled a list for you to work from@Rob KA2PBT for the telemetry. See anything wrong with it or missing?

Is there anything we could spray on the wheels to give them a little extra life? Rob KA2PBT You know… Something like flexseal?? Daniel Werbin i am not confident in that working Rob KA2PBT Neither am I but we’ve done crazier things Rob KA2PBT Any intel from the ESC guys?? Daniel Werbin the firmware guy is out for a few days and will look at it when hes back. the other guy is expressing a new esc to make sure its not that Rob KA2PBT Ahhh Did you send me the firmware? Daniel Werbin stand by Rob KA2PBT Don’t rush I’m driving Rob KA2PBT (Into those of you wondering hands free speech recognition) The President of Making © Nobody was. The President of Making © Pick up the hardware for todays tasks. Kyle Watt @Rob KA2PBT am being sent to check in Friday afternoon again? William Browder-Little @The President of Making © I'll be picking up two trash cans for the shop (one stays outside, one stays inside). Thinking I'll pick up some electrical components to set up that outdoor light on a switch. Planning to get components to get outdoor outlets in place as well. Should I pick anything else up? The President of Making © I would make the outside receptacle a double duplex. Rob KA2PBT @Kyle Watt ... are you still at NJIT? Kyle Watt Getting my MS, yes. William Browder-Little @The President of Making © Yep! I was thinking double duplex or if I was feeling fancy I could do two double duplex that ride on two separate existing breakers. William Browder-Little If I get that fancy, one would go on the left next to the 220V feed, one would go on the right near where the welding bench was. Rob KA2PBT I'm thinking we build some sort of permanent patio roof or awning for the outside area Daniel Werbin I wish William Browder-Little Dan and I have tossed that idea around. William Browder-Little I'd like to level the area before doing something like that. Don't necessarily need concrete. Would be pretty cheap to get started. William Browder-Little We're looking to make a long narrow storage shed that runs along the fence opposite to the shop door. We want to do that first. Rob KA2PBT I'm not talking fancy .... wood pitch frame with corrugated roof panels on top Rob KA2PBT 12x12 would do it .... 18x18 ideal William Browder-Little Definitely agree. Could be done cheap. Might ask Dan to draft that today while we have a quiet day at the office. William Browder-Little I remember it only being about $500 in material to make a similar construction that was about 18'x40' out in our field. Didn't last due to lack of maintenance but it wasn't hard or expensive. William Browder-Little We even have a three point hitch auger thanks to my ex girlfriend. Rob KA2PBT great ... simk four posts ... little concrete .... framing on top ... panels are about $15 for 26"x96" ... need about 10 of those .... coming in well under $500 .... maybe closer to $300 William Browder-Little Thinking I agree with that. I get paid Friday. Let me see if I can work out a surprise weekend project (as soon as we're done with the cart for the season, of course! Whoops) Rob KA2PBT ... uh yup. William Browder-Little Still, it'll benefit us for the future. William Browder-Little Seems like more and more WC2FD/721MB shenanigans are going on at the farm. Hoping to support that.

Daniel Werbin Yes I'll do that shortly Rob KA2PBT I’m confident in the precautions we took Tucker KD2JPM The shopping cart PRS car has been spotted Daniel Werbin Bad news everyone: the main bearing has been damaged by the welding. Daniel Werbin I can make this deduction because it is now smoking Daniel Werbin Also we can't change it because the gear is now welded on and.. Yeah lol Rob KA2PBT Sometimes it’s not about the destination it’s the journey Tucker KD2JPM Need a bearing? https://i.groupme.com/1125x1500.jpeg.2b5f708b81304d30b85a24d920241e4a Pete Cornell Sounds like the return current founds its way through the bearing? Rob KA2PBT Probably just heat .... we clamped it at the shaft below the gear in hopes of keep the current away from the motor and providing a heat sink ... just not enough.

I'm pretty sure nobody totally documented the last 48 hours here on the Group. We did not race today, and will not tomorrow either. Our drive train, mainly motors failed us. In the process of start-up, then testing both of the motors internally blew up. I want everybody to know that many hours by many people went into this years car, that only the frame, seat and steering wheel were reused. This motor problem is just a blip in the history of this team, and I am proud to have had a hand in building it.@Daniel Werbin had a vision that is outstanding,@Asst Project MGR and@Rob KA2PBT chased down parts and support services, not to mention@Jimmy P. ,and@Tucker KD2JPM & his Grandfather who was attempting welding repairs at 02:00 last night, and so many others who got involved even as things went bad. I believe our 721 motto "We Always Win" will come into play soon. Thanks KP Daniel Werbin I'm very proud of what we have achieved too. the rest of the kart is very, very solid now, we just have a few more bugs to work out Pete Cornell Well said. No expiration date on winning, and the evolution of the 721 MCB racer continues. Congratulations to all! Pete Cornell Do we get a post mortem on the motors at some point? Was this heat again? Karen KD2HII We were proud to wear our shirts at Maker Faire today. Daniel Werbin post mortem: suspension worked out great, handling is amazing. brakes work great, stop the kart so fast that the front squats right down.  Handles bumps like a champ too and no longer tripods.  as for the motors:  so it turns out that the first motor was defective, it failed below its advertised rpm and the "kevlar" around the rotor let go, causing the magnets to touch the stator and the system to disintegrate.  the second motor worked great until the gear detached.  to attach it again, we welded it back on taking many precations to not overheat the bearings, but it appears that failed too, as when it was ran again the bearings got hot enough to smoke, which then failed, allowing the rotor to move enough to touch the stator, and then that too caused catastrophic rapid unplanned disassembly of the rotor Daniel Werbin https://i.groupme.com/4032x3024.jpeg.af81f5065f3e4b28868951d83959944d Daniel Werbin https://i.groupme.com/4032x3024.jpeg.733842146fc642ddb3b9fea3055525b3 Michael Unangst “catastrophic rapid unplanned disassembly”......I might borrow that one👍 Michael Unangst why the quotes around kevlar? Were they not as skookum as advertised? Daniel Werbin because china Daniel Werbin we're not sure if its actually kevlar or just some kind of fiber of some vague resemblence to kevlar Tucker KD2JPM “Kevrar” Tucker KD2JPM Credit to @The President of Making © Pete Cornell Ah so!

Dave Hooper 2 it varies closet river at the moment is green river near moab The President of Making © Very good, glad to have you aboard. You are 1 ham test away from being a full member here. Just saying... Dave Hooper 2 one of these days Daniel Werbin so I found the solution to fix the startup torque issue: the AS5047 magnetic encoder Daniel Werbin unlike hall effect sensors it doesn't need to be mounted inside the motor, so no mods required, it can sense a magnet on the tip of the driveshaft Daniel Werbin https://youtu.be/_gBN6H3Kumw Daniel Werbin bottom wheel is encoder, top is hall effect (sensorless is even worse) Rob KA2PBT But .... there are multiple magnets on the rotor .... can you draw a picture? Evan Markowitz Magnets... How do they work? Rob KA2PBT Let’s not go there Daniel Werbin https://i.groupme.com/2016x1512.jpeg.d27a322913584ff69d132a9e296b0dfd Jeanmarie Murray Daniel, You are a man of many talents. Daniel Werbin instead of drilling into the motor casing we can just stick a magnet onto the end of the shaft and the encoder will when within 6mm of said magnet provide rotation angle of the motor to 4096 steps Daniel Werbin thank you! GroupMe Asst Project MGR removed Dave Hooper from the group. GroupMe Asst Project MGR changed the topic to: We always win....... Daniel Werbin https://www.digikey.com/product-detail/en/ams/AS5047D-TS_EK_AB/AS5047D-TS_EK_AB-ND/5125788 Daniel Werbin for just a few dollars more then the sensor itself you get a pcb and a magnet. seems like a good deal to me Daniel Werbin and there is a spot that the sensor can fit inside the gearbox Daniel Werbin I figure we will encapsulate the whole sensor in epoxy or something once its working to protect it from dust and grease Pete Cornell Build in two, for redundancy with a molex connector? Seems pretty critical to operation. Daniel Werbin there is no super easy way to have 2 hall sensors listen to the same magnet, nor the controller to listen to both at the same time Daniel Werbin however, it will revert to sensorless operation after 3000rpm or sensor failing Daniel Werbin It only uses the encoder for 0-3000rpm, after that it ignores it Pete Cornell Nope, one on each motor, only one connected at a time. Just a thought. Daniel Werbin oh no worries, there will be spare sensors =) Pete Cornell On a side note, if there is a several hour build session (with some lead time), I'm willing to make the journey to help...... Daniel Werbin sweet! Yeah I'm sure it will be happening again. probably going to cool down on it for a little bit and then get started again, if we can keep a slow burn then we can get it all going Daniel Werbin and not have to rush at the end Pete Cornell Sure thing! It's just a very long drive from Metuchen, so need bigger ROI on time than local folks. Look forward to it. Rob KA2PBT Ahhhh I didn’t get the extra magnet thing ..... I thought you were trying to sense the magnets in the motors ..... now it makes perfect sense. Can you draw a funny elephant now? Daniel Werbin that exceeds the limit of my talent Pete Cornell Can you wire frame it?

Is there another “use case” we could look to source from? Daniel Werbin Not for a price we can afford Ben Boniface @Daniel Werbin I have a lot of click button, wait, fix some stuff repeat work to do today, can you send me the motor specs for our last motor choice Daniel Werbin so the motor we are looking at now is the TPPOWER 4060 with the 8Y winding (720kv), 8mm D shaft Daniel Werbin we had a few people very much defend that motor's ability to withstand its rated rpm Michael Unangst any comment from the manufacturer about the rapid disassembly?

Daniel Werbin Nope not yet William Browder-Little Ejection seat involves jumping at a slight angle to avoid the tail Tucker KD2JPM Ejection sears and parachutes are for the pessimist @Rob KA2PBT William Browder-Little @Tucker KD2JPM restore is happening over winter so according to Dan probably not until spring. Due to the requirements of the owners of the farm (fancy way of saying "parents") the plane has to be out of the garage by June. Dan says if it isn't out by then, he must have died. William Browder-Little Restoration is a strong word. It -really- doesn't need much. It was ready to fly not too long ago. Ben Boniface That's something of a catch 22 as I see the lost likely way of Dan dying is via flight of that plane William Browder-Little This is the first time I'm seeing Dan risk his life by doing anything more than driving so I'd say that's a fair statement. William Browder-Little Meanwhile I'm the dumbass that does things like have a ball of fire engulf their face. Happened last night when I was using the redneck method of reseating a tire on a rim. William Browder-Little In comparison I'd say Dan is wonderfully tame. Ben Boniface @Asst Project MGR i remember we had a fun time using the redneck tire setting method William Browder-Little Eyebrows, eyelashes, beard, and bangs got a tiny bit singed (enough to make it look like I had done some woodworking and got some shavings on my face) but aside from that it was just a good way to warm myself up quickly. Daniel Werbin I even warned him Rob KA2PBT Experience is the best lesson ... assuming you live through it. Ben Boniface Actually correct me if I'm wrong @Asst Project MGR that was @William Browder-Little tire? Asst Project MGR It's happened more than once. Asst Project MGR Still a solid method William Browder-Little @Ben Boniface I don't think so! I've only done this on the farm three times now. Tucker KD2JPM Leaned today that RIT’s Engineering dorm uses 4 independent motors on their PRS car. They beat MIT and took third at World Maker Faire this year.

Daniel Werbin already have those planned. some angle grinding and light welding required but me and kp are going to endeavor to do that tomorrow Rob KA2PBT OK then! Daniel Werbin the only hold up right now is money for these parts Daniel Werbin @Tucker KD2JPM how many watts is the brushless scooter motor you have? Daniel Werbin is it the 1800w? Tucker KD2JPM I’m trying to remember what motor you’re talking about. Tucker KD2JPM Remind me again, the only motor that comes to mind is the big ass belt drive motor Daniel Werbin on your prs karts, the silver can with the sprocket on it Daniel Werbin and black wire coming out the back Tucker KD2JPM Oh that’s a question for @Hunter Leonard Tucker KD2JPM I forget what it is Daniel Werbin if its 1800w, I'd love to get some critical dimensions to be able to plan for working tomorrow without the motor in hand Hunter Leonard Yes it's the 1800w from amazon Hunter Leonard What dimensions do you need Daniel Werbin sweet! i cant find reliable dimensions literally anywhere, so basically all of the important ones. can diameter can length shaft diameter(I think its 12mm ) shaft length from motor face also I see two what look like M4 screws to face mount it to something, can you tell me the spacing of those apart?

Daniel Werbin Usually two connectors with 1 wire that can plug together, i believe white Rob KA2PBT You’re not instilling a lot of confidence.... Daniel Werbin the situation is basically that these controllers can reverse the motors via programming but the ones i bought dont have the wire outside Daniel Werbin but if their controller does, i can see where its soldered and make my own Daniel Werbin theres lots of unused pins in my circuit board Daniel Werbin otherwise i have to play swappy swappy with the wires and that will take forever Hunter Leonard Is the motor spinning the wrong direction and you want it to go the other way? Hunter Leonard Swap any 2 motor phases and their matching hall sensors Daniel Werbin is it really that easy? Daniel Werbin Have you done that? I didn't realize the hall wires colors corresponded with the phases Hunter Leonard Yeah, each hall sensor gives feedback for a corresponding phase Daniel Werbin oh wow thank you that makes life a lot easier Daniel Werbin maybe the kart will move under its own power tomorrow!

It was not that straight forward Daniel Werbin Swapped motor phases yellow and green, had to swap blue and green Halls The President of Making © https://v.groupme.com/22123015/2019-10-13T02:11:38Z/392afdf3.640x360r.mp4 https://v.groupme.com/22123015/2019-10-13T02:11:38Z/392afdf3.640x360r.mp4 Michael Unangst zoom zoom The President of Making © https://v.groupme.com/22123015/2019-10-13T02:13:51Z/3896796b.640x360r.mp4 https://v.groupme.com/22123015/2019-10-13T02:13:51Z/3896796b.640x360r.mp4 Dustin Fisher Nice guys! Thats awesome! GroupMe The President of Making © added Edward Carruthers to the group. The President of Making © @Daniel Werbin please post a pic of the back of the seat. It will help to figure out how we are going to fix it. TU. Daniel Werbin whats wrong with it The President of Making © I want to replace the back. Daniel Werbin oh okay, copy Daniel Werbin also to update you on brakes, me and @Asst Project MGR looked at the splitter and it is dished on all 3 ports which is causing the crush washers to not seal. he is going to machine them flat and replace washers GroupMe Asst Project MGR added Darren Occhiuzzo to the group. Rob KA2PBT Saturday night at 6:30pm, the Meet and Greet semi-potluck will begin. All Makers, Vendors, Educators and otherwise are welcome to attend. If any of the former knows of any makerspace reps, does volunteer work, or in any is involved with community projects, please invite them Rob KA2PBT Power Race Series participants, Matt Hagan is managing the race event and should be your primary contact. I can say that all race teams should bring their own pop tent if that want some shade. Ideal Farms will be providing a stick and MIG welder, welding table, oxy-acy torch and mid-sized air compressor as well as some other metal working tools. There may be a group doing welding demos, in which case, the arc welder will be shared.

Just needs to be connected to bms then battery alarm Michael Unangst @Dustin Fisher new 18650s or salvaged? Daniel Werbin They look awesome! Daniel Werbin what cells are they? Steve KD2JQK Headed to the beach a few days to do some surf fishing bringing my HF with me in the car Steve KD2JQK We'll be down in North Wildwood Steve KD2JQK Right now on 40 Hunter Leonard @Daniel Werbin they are new salvaged cells... I bought them from a guy doing a moped conversion and had already made different packs with new cells but never used the packs then sold 300 Samsung cells to me, we only used about 150 total for both batteries. They're all at least a few years old but never used in that time Hunter Leonard And yes 18650s, not sure of the model but they are 2AH Daniel Werbin What kind of rated current? Hunter Leonard Dont know actually, assumed 5-8amp continuous? Daniel Werbin Sweet, sounds like you got done good ones Hunter Leonard After the entire deal with the guy was over and I sold parts that I didnt need and kept the cells, I had made 100$ Steve KD2JQK 7.222 Daniel Werbin wow Zoom..Zoom.. 41 hours till Power Racing at Ideal Farms Daniel Werbin @Tucker KD2JPM @Hunter Leonard what voltage are you guys using? are you using 30A fuses? Hunter Leonard 48v and yes Daniel Werbin do you have any extras? Daniel Werbin I may have overestimated how many we had. we ran 24v and have a ton of 60a but converted to 48 and only had 1 and now none Daniel Werbin if you have at least 1 spare we would be really appreciative Daniel Werbin never mind, not as pressing now, nick found some with fast shipping The President of Making © I have the silicone #10 wire @Daniel Werbin Daniel Werbin great, bring it with you tomorrow The President of Making © Is somebody in charge of packing the trailer?

Devlin M *big Asst Project MGR a project is underway to evaluate how we can use NISSAN LEAF Gen II cells as part of a dual purpose Ham Radio and PRS cart power setup Asst Project MGR the big green ones Asst Project MGR one pack has already been ordered and will be converted from 2S2P to 4S1P for testing Asst Project MGR several other teams have made good use of the Leaf G2 packs Michael Unangst got a link those packs? @Asst Project MGR Daniel Werbin ebay seems to be the best source Daniel Werbin each pack after factoring in used wear, results in 2s2p 7.4v @ 48ah Daniel Werbin when converted it will be 14.8v @ 24ah Daniel Werbin for around 80 dollars each for 1 qty, or if you buy them by packs of 8, around 56-60/ea Asst Project MGR https://www.ebay.com/itm/Nissan-Leaf-Battery-G2-Module-Lithium-Ion-500-wh-7-6v-per-module/113700519053 Asst Project MGR the current thinking is to build 2 ea packs: HF waterproof case 3ea 4S1P leaf packs to yield 48VDC 24 AH. Probably use a SB series Power Pole connector. Asst Project MGR either pack or both could be fed into a DC Buck converter like this for 12VDC Asst Project MGR https://www.trcelectronics.com/View/Mean-Well/SD-350C-12.shtml Asst Project MGR @Daniel Werbin what are the specs on our current green batteries Michael Unangst yeah 4s full charge voltage runs a tad hot for normal 12VDC stuff Asst Project MGR so close yet so far away. Daniel Werbin when new, 6s1p @ 16ah, 4c discharge rate kind of but that stresses it Daniel Werbin nowadays, they probably are 12ah Daniel Werbin internal resistance creeping up Daniel Werbin the leaf batteries are rated to 250a discharge (in 2s2p so each cell can do 125a) Asst Project MGR and this weekend on dirt we used how much power per race of how many laps? Daniel Werbin tell them about the capability as a field ham power source vs group 27 sla you told me Daniel Werbin each sprint used 10ah roughly Daniel Werbin for i think 25 laps Asst Project MGR if each pack is 48VDC at 24AH- then minus conversion efficiency barring any dodgy math: Asst Project MGR each should yield 12VDC at around 90AH, which i believe to be 2 ea group 27 SLA since you can only get at about half the power in them Asst Project MGR the pack will weight about 22-25 lbs and be around 12 x 9 x 6 plus packaging Asst Project MGR each group 27 battery is around 55+lbs Daniel Werbin group 27 Dimensions(in):12.44 x 6.77 x 8.75 Asst Project MGR @Michael Unangst this is your wheel house, so feel free to correct me Daniel Werbin but ideally this means that in a 12x9x6 @ 25lb package, you get the equivalent of 25x7x9 @ 110lbs SLA Daniel Werbin since you can fully discharge lithium and not hurt it vs 50% dod for sla Daniel Werbin and also cost. leaf batteries are only around 60-80 dollars each module (need 3 for our 48v24ah pack) vs my quick google of group 27 deep cycles saying that new they cost around 300 each? Daniel Werbin dc/dc converter is 80 bucks i think Daniel Werbin so not only are they better in every single way, they are also cheaper Michael Unangst i know enough about lithium to get in trouble. sounds like you’re already close with the math. usable energy without overvolting 12VDC with just depends on what the voltage curve looks like Asst Project MGR you can get a group 27 for about $95 at Sams or the like (Marine and RV) Daniel Werbin oh okay Daniel Werbin so for a slight cost disadvantage you get something that one can actually use by themselves Asst Project MGR to use these at 12V i think some type of DC Buck is required. Daniel Werbin I can carry 25lbs in a backpack or by hand. i cant carry 110lbs in a backpack or by hand easily Daniel Werbin yeah its better if we do that. just makes it easier Asst Project MGR it seems like if the cart wants 48VDC, might as well have a DC buck that starts there so there is a minimum of work to switch packs over from radio to racing and back Daniel Werbin also higher voltage means more efficient wiring but for these short runs who cares Daniel Werbin and in theory battery should be capable of sustained discharge rates of 125a @ 48v, or 6kw Michael Unangst depends what you’re powering with a little extra voltage is gonna matter. I’m sure Spud’s little 12VDC tractor will go like a motherfucker at 14.8 under load Daniel Werbin though I probably wouldn't recommend that Daniel Werbin spuds tractor would really haul at 6kw though � Asst Project MGR choo choo Daniel Werbin or if we just feed its motor 48v Daniel Werbin then it will really move Daniel Werbin briefly... Michael Unangst for a minute Michael Unangst before ya let the smoke out Daniel Werbin just submerge the motor in liquid nitrogen Michael Unangst I wonder how noisy those buck converters are Michael Unangst have to give one to @Troy Godfrey Daniel Werbin i think it was a meanwell Daniel Werbin cant be that bad hopefully Rob KA2PBT I seem to recall .... when we started this journey.... I said we should look at Leaf Batteries... Daniel Werbin We had these batteries already Rob KA2PBT ... and chains instead of belts ... Rob KA2PBT ... and rear braking ... Daniel Werbin Uhuh Rob KA2PBT Just sayin .... 😁 Daniel Werbin Send me your cad files for your design and we can review together Tucker KD2JPM Trying to program a jelly controller to use the motor both teams used for PRS and the kelly programming software is asking how many poles the motor has, do you know @Daniel Werbin Tucker KD2JPM Kelly* Daniel Werbin not a clue Daniel Werbin you can probably figure it out by either opening the motor up, or putting an oscope on the wires and spinning it Tucker KD2JPM I found a picture online of one opened up, how would I determine the amount of poles from that? If that doesn’t work, how would I used the scope to do that? Daniel Werbin https://helihack.co.uk/poles Daniel Werbin count the pairs of magnets basically Daniel Werbin well its not pairs, its just the number of magnets in the circle Tucker KD2JPM I was able to find it, 6 poles Rob KA2PBT https://youtu.be/ud3gb7IDJPk Rob KA2PBT Sparkfun lidar Rob KA2PBT Ironically a Barbie Jeep https://i.groupme.com/230x306.gif.59b6f4ebc1cf4a3b966f7af6ae92f0b2 Michael Unangst Speaking of Jeeps, I stumbled across this one reddit.

Rob KA2PBT .... and this is what Margret Hamilton would say: Rob KA2PBT "Young whippersnapper, when I was your age, I sent 24 people to the ACTUAL MOON with my software in 4K of RAM and here I am clicking your button and it takes ten seconds to load a 50 megabyte video ad and then it crashes I'm not even ANGRY with you, I'm just disappointed.” Ben Boniface @Kyle Watt you think Matlab pretends...look at LabVIEW. Ben Boniface I wrote two identical RT models of a battery. The one compiled from labVIEW had 40-60 microseconds of overhead compared to the same algorithm compiled from C Tucker KD2JPM What motor controller are you using @Daniel Werbin Daniel Werbin Mophorn 1800W Electric Brushless DC Motor Kit 48V High Speed Brushless Motor with 32A Speed Controller and Throttle Grip Kit for Go Karts E-bike Electric Throttle Motorcycle Scooter and More (1800W) https://www.amazon.com/dp/B07KF8M5W6/ref=cm_sw_r_cp_apa_i_-fOlEbY51X0VV Tucker KD2JPM You’re using the controller that came with the motor?
