Maybe someone has thought of this before me (would love to see a working version if so), but here’s my idea:
Remote-less electric boards are a thing, but the only ones I’ve seen are the type that gradually become slower and slower until you have to push again. My idea is to use a pressure sensor (similar to the one on Onewheels) at the back of the board to detect when you have your back foot on. If your back foot is on, the board will maintain your current speed using a battery and motor as usual, but if your foot is off, it will go into free-roll mode. This way, the board goes only as fast as you push, but you don’t have to keep pushing constantly to maintain your speed, and breaking works just like on a regular board.
I could see something like this being a direct replacement to usual free-ride longboards. Disadvantages are the usual of course: no regenerative breaking, no going faster than cars (unless you have super-human pushing strength )
Would it be possible to make something like this by simply reprogramming a VESC? What do you guys think?
