Hi Jeremy!
I used the shaft encoder out of a track ball for my robotic project(same
thing but a bit bigger). You do not need the IC out of the mouse just take
the shaft encoder and use it with a IR led and detector pair. If you are
going to use the digital inputs to count the tics use a smith trigger to
clean up the detector output else use the encoder routine supplied with the
handyboard IC library. If I recall correctly this routine requires you to
connect the detector to the analog inputs.
I hope this helps.

| The IR led I assume would be the transparent one and the detector would be the black one? There are 2 leads on the transmitter and 3 on the detector, how and where should I connect it to the HB? Any diagrams available? If this works, I have about 10 (...) (27 years ago, 14-Nov-97, to lugnet.robotics.handyboard)
