More and more people are experimenting with Kalman filters, gyros, and accelerometers. A fellow named Tom Pycke has been working with Kalman filters for different tasks like autopilots and balancing robots. Tom has gone above and beyond by posting source code, schematics, and board files plus a cool video of his project in action. Bravo Tom!

A gent by the name of Sylvain Bissonnette has crafted quite a large amount of really interesting projects. Perhaps the most striking he has come up with is a lighting system that uses monster 3 watt RGB LEDs to drench a room of his choosing with luscious mood lighting. The only downside is that linking to the project page redirects you to the front page. The link for the RGB Mood Lighting is in the top right corner of the screen. C’mon Sylvain, how you gonna play me like that!?
