My little tribute to the ScanJet music video: http://www.youtube.com/watch?v=kj7-Be... - I spent a couple hours piecing through that video note-by-note to match the programming exactly. The setup was originally used to test the Arduino AccelStepper library; the three knobs control acceleration, position, and maximum speed (top to bottom). The switch controls "lock mode", i.e. leaving the stepper energized after moving, to save power. The button goes into "constant" mode, with the speed controlled by the MaxSpeed dial. It also starts Fur Elise if the Acceleration knob is set to 0. And all the information is displayed on the LCD; the meter is used to indicate current draw by the stepper.

Not bad for a stepper motor that's been sitting in a parts box for over 10 years since I didn't know how to use it... =P
