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

BEP Application: Servocore Walker
The following instructions detail how to build a Servocore walker. A Servocore walker differs from a regular walker by utilizing the internal electronics in unmodified servos, which give position feedback from the motor in the servo. This position feedback allows for very long stride lengths without the use of mechanical stops or springs.
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 […]
New Product Return Policy
We've been having our usual post-Christmas trickle of product returns (for free support), and we're noting more-than-usual levels of incomplete paperwork on the parcels.
