ARVP_Electric Skateboard

Inspiration

I saw a really cool video about someone who did a similar thing and used a wii remote and a raspberry pi to control an electric skateboard he designed himself.

What it does

It is an electric skateboard. There is throttle, brake and reverse.

How we built it

I built the battery myself from 18650 Samsung 25R cells, it is an 8S4P configuration. That is connected to a JKBMS BMS, which is what balances it and charges it. I built the charger myself too with an AC-DC adapter and voltage converter with current limiting and fan so it just plugs from the wall straight into the battery. I then use a Flipsky FT85BD dual FTESC to drive the dual 270KV motors with a3:1 belt ratio for the rear wheels. The ESC is controlled from a Flipsky VX1 controller using PPM. All of this is encased in a metal enclosure I laser cut and bent and then attached to the skateboard.

Challenges we ran into

This project actually went very smoothly. The only hiccup I had was when making the battery I accidentally shorted a cable and melted it a bit since it is about 160A, but it ended up okay.

Accomplishments that we're proud of

It has a top speed of about 38km/hr with enough power to carry 3 people. It also looks pretty clean.

What we learned

PPM sucks and I should use UART going forward. Also a VESC instead of an FTESC.

What's next for Electric Skateboard

Maybe upgrading it to 4 wheel drive rather than 2 wheel, and I want to design and make tracks for it myself, like a snowmobile, so I can use it in the winter.
