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

They are evil vampires lurking in the dark. Flies on the other hand are jovial and rich in protein. Cats usually specialize in them. But cats don’t tackle mosquitoes very well.. . I […]
