Electric Penny Board

Board Bottom

Builds

The build for the board is the same as my regular Penny clone [https://mcwain.net/finally-finished-my-first-penny-clone/], but in orange instead of blue. However, this one has a giant battery, a couple motors, and some circuitry to make it go super fast.

The plastic cases were designed in Autodesk Fusion 360 and printed on a Prusa i3 MK3 in PETG. You can download the STLs from Thingiverse here. It took quite a few tries to get the sizes right as I had to be creative where all the wires should go. After all is said and done, I think the build is fairly clean.

The whole board is controlled via a remote that can be stashed away in a pocket or your backpack. Both the board and remote are rechargeable, so it shouldn’t ever need to be disassembled.

It’s rated at 10 miles (16km) range and 25mph (40km) top speed, but I haven’t been able to take it above 40% power yet.

If you want to try your hand at building one, have a look over at Enertionboards.com or MBoards.co (ran by Mike Beard for the electronics and Woodcraft.com for the wood and tools to make the board.

Issues

If I had to do it all over again, I’d put in some runners for the power cables and maybe pick a better ESC. The board itself makes a rattling noise in the back that I believe is coming from the bearings in the rear wheels. I attached foam between the plastic cases and the wood board to prevent any squeaking and I also added some rubber 1/8″ spacers to the trucks just to rule out the noise coming from there. Maybe someday I’ll find the culprit. Until then it only bothers me on rougher terrain.

Edit 17Sep2018: Found it! The kingpin was loose on the board side. I tightened it up all the way and loosened it until it was how I like it. Maybe someday I’ll stick a rubber washer down there to kill the last 1% of noise.
