I recently built an optical encoder from scratch, and it was a ton of fun. More recently I've been looking into how force feedback works, and I'm currently gearing up to implement it using a motor/encoder/controller setup and ODrive.
The idea here is to shine a light on these hidden interests and the little (or big!) mental blocks that come with them. If you're already rocking in those specific areas – or you've been there and figured out how to get past similar hurdles – please chime in! Share some helpful resources, dish out general advice, or just give a nudge of encouragement on how to take that intimidating first step.
Let's help each other get unstuck!
