More motion experiments

Quick update on the motion stuff...

I created my own driver software that interfaces directly with LFS and hooked the motors up to Pulse Width Modulated outputs on the USB board.

The result is much smoother motion with better resolution. Video can be seen here:

I'm starting to investigate micro-controller based positioning implementing the closed loop control inside a PIC microcontroller. I've also got hold of some full size motors and successfully tested them with my motor driver board. Next step is to work out some method of connecting a decent crank to the real motors...
