Solarbotics came back from the 2003 Seattle Fall Robothon with a 'Best Engineered' award for our Sumovore Mini-sumo kit! We'll get a picture of it up online shortly, but in the meanwhile, take a boo at our pictures of our trip there! Read More...
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

New Vibe Motors!
We've finally come upon a suitable replacment for the venerable, discontinued VPM vibrating pager disk motor. Ah, it was a splendid device, but it sure was easy to break those motor leads... Ah! But the new VPM2 has wires prebonded to the motor, and it's slightly smaller too! We welcome our new vibrating disk motor […]
