This week: Blizzards. Ice. Snow drifts. Rather sunny and warm. Wait, what? Yup, we've seen it all this week folks. All that's left is for delicious pastries to start falling from the skies, and we can check off the last item on our home-made "meteorological phenomena" list. And boy, you have no idea how long […]
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
