I after building this "monowheel", I noticed it could jump. I tried making it into platformer but this kind of wheel's finite number of uses kept getting in the way. All attempts made to extend it failed. I knew from others that it would be a problem but I apparently underestimated the severity of it.
The plank on the 3rd layer was, without hacking, rotated 2^23+46 radians to keep the center from tilting.
Should be simple to wire.
Enjoy and don't forget to leave a rating.
if I made any typos, I blame it on it nearly being 1:00 am
