Re: Crab drive without a pot

A couple of years ago our crazy electrical guy made a full rotation potentiometer by cracking it open and cutting off the stop. (Not recommended, you can screw things up by putting voltage across a shorted potentiometer)

There are ways to use optical sensors to encode position rather than motion.
