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

Project: LED Earrings

The idea of adorning oneself with glowing bits has been around forever, but instead of smearing ourselves with phosphorescent jellyfish or placing fireflies in ears like some uncivilized cavemen we went for simple LED earrings. We made a build that involves a simple slow-scroll RGB LED and a few reflective bits to bounce that pretty […]
