Ingredients

• Two KP4M4-type stepper motors (or similar)
• An old IBM-PC power supply unit for +5v and +12v
• Assorted plastic bricks, etc. from that Danish Company
• Double-sided sticky pads to hold the motors in place.

A minor departure - I trimmed the motor spindles' length and, since I wanted to use the smallest (8-tooth) cogs, I filed the spindles down to fit rather than file out the centre of the cogs.

• The circuit I used and a simple QBasic Program to control it.
