[CGPatterson] ended up making this case from a single sheet of transparency film. The project is basically papercraft. He started with the dimensions published on … [Read more...]
The biggest benefit to using the BeagleBone is it's 700 MHz ARM processor. If you're just messing around with basic I/O that power is going unused, but [Nuno Alves] is taking advantage of its power. He built a PDF password cracker based on the $85 development board. We recently saw how easy it is to perform basic I/O using the BeagleBone. Those techniques are in play here, used to drive a … [Read more...]
[Satiagraha] let us know that Texas Instruments(TI) has given out a neat "LED Reference Design Cookbook" PDF. The document contains 17 some odd little projects featuring different TI ICs and ways of using them to control LEDs in things from backlights to torches to solar lanterns to advanced PWM control!

[Jason S. Babcock] and [Jeff B. Pelz] put together this paper on building a simple, lightweight eyetracker (PDF) to foster the creation of open source eyetracking software. All of the components are mounted to a cheap pair of safety glasses. The eyetracker uses a technique called "dark-pupil" illumination. An IR LED is used to illuminate the eye. The pupil appears as a dark spot because it doesn't … [Read more...]
