Circuit: Stepper Motor
Dave Hrynkiw
July 12, 2007
This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:
- 74AC240 Octal buffer chip
- 4 x CP0.1µF capacitors
- 100k resistor
- 2 x 47k resistors

New Wheels
Remember those bad-boy wheels you saw on Strongbad? Well, they're now available! But be warned - we don't have the sleeve to fix the 2mm shaft to 1/8" hole diameter gap, so you'll have to improvise something yourself. Otherwise, your robot will have a bit of a lope to its roll!
