Electric Skateboard
Here is a gallery of both my V1 and V2 E-board that i build within a year. This was before commercial options existed only open scouse forums.
My second homemade e-board is Powered by dual 4.5kW motors, VESCs, and a custom 5S6P Li-Po (now upgraded to 18650 Li-ion). The controller was a a modified Wii Nunchuck but due to instability of the signal strength i changed it to a firefly remote it can hit 43 km/h in under 3 seconds with ~16 km range. The board still works today and is quite fun fun, flexible build that kickstarted my interest in electronics and CAD.
