Circuit: Stepper Motor

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:

  • 4 x CP0.1µF capacitors
  • 100k resistor
  • 2 x 47k resistors

New Books, Closed Monday 2nd

So apparently Monday here in Albertaland is "Heritage Day". Which, quite frankly, sounds rather uninspiring. Don't get me wrong - any excuse for a statutory holiday is a good one. But the name seems rather vague and underwhelming. And thus I began my quest to find the true meaning of Heritage Day. So as any […]
