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:

  • 74AC240 Octal buffer chip
  • 4 x CP0.1µF capacitors
  • 100k resistor
  • 2 x 47k resistors

Interesting Mini-sumo build

This mini-sumo design by Jeremy Bloyd-Peshkin features our wheels, and one of our favourite building materials, Sintra. We can't laser-cut sintra (PVC=bad stuff when burned), but milling it works well, as this builder shows. The asymmetric motor layout works, as proven by this contest-winning design (scroll to the bottom of the page).
