: What about a magnet in the wheel and a reed switch close to the wheel on the 'fender' and have the Stamp count the # of times the reed switch is triggered in a given amount of time. Thus giving you your speed.

We did something similur to this for our tower. It used a limit switch firing when ever a bolt on the shaft pressed it. With a bit of work, and some input from the motor we could also track position. Here is the code:

lift = lift + ( (p2_y / 128) & (RC_SW1 &~ contSwitch) ) - ( (~(p2_y / 128) & 1) & (RC_SW1 ''&~ contSwitch) ) &~ hook_down
lastLiftDir = p2_y / 128
