I occupy a studio space in a building that is a former movie shooting facility turned into an artist hovel.

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

Cool project
Neil Sandstrom from the BEAM mailing list recently posted a notice about his "ShokHead" circuit built from our tutorial. What makes this project a bit different is that he mounted it on a VPM motor, so it's all self-contained. Here's what he says about it: Just finished!!! Check it out it is really small!! http://groups.yahoo.com/group/beam/files/Psyclesam/ […]
New Solarcell, the SCC2433a
In our continuing quest to find the successor to the Sunceram throne, we invite you to welcome the SCC2433a solarcell! It's the little brother to the SCC3733, with similar polycrystalline & epoxy construction. It's quite the power-house in direct sunlight, but be warned - the cell arrangment is skewed in favour of current generation, not […]
