Effective immediately, all the proceeds from the sale of Zendulum kits will be going to the Red Cross efforts in Japan. We'll change up the Zendulum laser artwork to note it as such shortly, and post the new pic. (Done!) Fractured Hinomaru inspired by James White's "Help Japan" poster.
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
