Ok, besides being a conjunction of two things we really love (Make Magazine & BEAM Robotics), it also is an open-source hardware project that is about little "T-Beams". This project is using the "KickStarter" model of sponsorship. Ask for pledges for the projects, and if the minimum is met (and it has - yay!), the […]
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: Turbot
The Turbot is a member of the Scophthalmidae family of flatfish and is almost completely circular. Turbot is often found partially buried in the seabed in sand, gravel, rocks and sediment. Its fat content varies, but it usually contains roughly 1 gram of omega-3 fatty acids per 100g fillet. Barring advances in genetic engineering, we will not be building that kind of Turbot. However, this kind of Turbot can be built with a soldering iron.

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 […]
