I didn't answer this at first because I'm not really quite sure how to describe it. It's a custom score reel... sort of.

Not sure if I'll ever put the finished design into a cab. The sketchup model looks very good and my calculations show it to be functional. The major problems I'm encountering are A) finding motors/servos/steppers that will work that are cheap enough (my model requires one for each place value) I can't quite work out the forces involved and B) feedback which is, what I hope, the notches will solve.

The controller requirements are getting beefy too. Every time I add a new feature, it practically doubles my IO requirement. For the morons who will inevitably poopoo that statement. To give you an idea, the motors require two I/O each so for three digits, that's six I/O. Add feedback and I just doubled my requirements to 12 I/O. I know I can reduce the I/O requirements through refining the circuit, such as using only N+1 I/O for each motor, but it's too early to work those out anyways. I'm using an Atmega32U4 so I have plenty of headroom,  I just don't want to commit the final circuit to a controller better used elsewhere.
