We're very excited to announce these new "baby" versions of the popular GM2 and GM3 gearmotors. These junior versions offer a 120:1 gear reduction ratio, built-in safety clutch, and 146rpm with 20in*oz torque at 5V drawing onlyh 90mA (620mA at stall). Take a look at them in the motors section of our website! The new […]
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 Bundle: The Northern Lights!
Ok, more like The Northern light. There's only one, but it creates lots of light! We made the SB-Firefly as a ATtiny85-based blinky light / "chewing-gum & duct-tape problem solver", that is also Digispark compatible. We made the Star Controller 3-watt RGB LED kit as an easy way to tame bright and power-hungry LEDs. We […]
