Ball Balancing – V2


Same story here as with the last couple of posts: these are some rather old attempts at improving a previous project, without much success, even after a considerable amount of effort… Hence the decision to still create a post as a future reference.

I went back to try and finish this ball balancing project, but after some improvements I started to get frustrated by the fact that the servos kept being “jittery”.

So here is something slightly more interesting, that I managed to work on this past week-end: my first foray into FPGAs !
