First post in this forum! I’m going to be covering my build here. I warn you that this is going to take some time. I’m currently doing 2 masters degrees and an internship and, although this project is in collaboration with my Uni, I prioritise the others.
Parts list: (Please take into account that the build is not completed, so although the majority of the parts I got were recommended by other users in different threads, I cannot yet say they are working properly, specially electric components.)
Board: Trampa Holypro deck with urban wheels Motors: Dual 6384, 170KV from APS Batteries: 12S5P (60x) - Samsung 30Q batteries Battery housing: Igus cablechain ESC: Focbox Unity from Enertion (hope it arrives soon!) Remote: APS remote BMS: 12S 15A Charging-only BMS Charger: 12 generic 4A charger Charging port: Waterproof 2-pin plug Transmission: Transmission kit for trampa wheels Shrink tubes (they have lots of sizes): Shrink tube JST adapters for motor-sensor cable to Unity (1.5mm JST to 2mm JST): JST cables
Things I’ve done by today (09/12/2018)
1. Board I got the board about a month ago:
2. Motor mounts/Transmission Next step was designing the motor mounts, for that I used Solidworks and a 3d printer to test prototypes. I ended with this thing inspired in many builds I’ve seen here:
I’ve noticed that, because of the truck’s curvature, once tightened, the mount wont stay perpendicular to the truck’s axis. So I decided to machine the trucks to make them flat on that area.
I’m currently looking for a machining company here in Madrid that will do the job, because of the small nature of the project, most companies are not willing to do it or charge me a crazy amount for it.
For the mounts, I’m planning on making them out of 7075-T6 Aluminium. To machine them I can use the CNC machine in my university, but first I want the trucks done to test some 3d printed prototypes on them.
For anyone interested, I will post the details and measurements of the mount once done!
3. Batteries I’m waiting to do everything motor mount-related before getting the batteries. To mount the batteries I contacted Igus and they were kind enough to sell me one of their cable chains. I’ve seen this idea on one of @Nowind 's threads. I thought it looked badass and so I decided to go with that:
I will be designing and 3d-printing some end caps. My idea is store the ESC and BMS on the bottom cable-chain and use the top one to store more battery cells in case the bottom one runs out of space.
Any advice is appreciated!!
Will update once I manage to find someone who can machine the trucks for me!
