I'll start by saying this was an incredibly rewarding project that I'm able to use every day. If you haven't had the chance to ride an electric longboard, it is like no other mode of transportation, fast, fun, and portable. Commercial electric longboards start around $1,000 which is tough to swallow for a financially struggling college student, thus my expedition started to design and build my own! Plus it was a good way to keep my 3D modeling skills sharp!
This project ended up costing me around $400 since I was 3D print a lot of the components and built my own longboard deck, which you can learn how to do here.
Lets get started!
Hands down the most difficult part of this project was figuring out what specific parts I needed, making sure they all worked together, and making sure they were all in stock. I put together a comprehensive list of all the components I used throughout the build process, where I bought them from, and how much they were. Hopefully this sheds some light and helps guide you through choosing components.
Since I also have access to a 3D printer, I wanted to take full advantage of it and save some money. I 3D printed the motor mounts, the gear on the wheel, the electronics mounts, and the electronics case. I wanted to do this right, which meant I needed a 3D model of EVERYTHING on the board. This was incredibly time consuming, but I uploaded all the 3D models I made to thingiverse, so feel free to use them as you please!
