OK, the single wheel on a mouse is able to discern the direction that the wheel is rotating. So I don't see where that would be a problem. I'm assuming that I'd feed +5v to the circuit and use 2 of the other 4 wires off the PS/2 connector for the encoder signal back to the controller, Right? (Which ones depends on the encoder used)
100 "Black wedges fit nicely in a 1 " dia wheel. so that'd actually be 200 Pulses per rev. so we're back to a very nice resolution.
I'm going to have to dig into this a little further.... I'm keeping my options open incase I run across a killer deal on servos(DC motors) that I can make use of without spending a ton and make them useable if they don't have encoders already.
(Are ready made encoders expensive? I've never seen a thread regarding them. Only about servos)
