Choreographed Christmas light show (x4)

[Lucas] is at it again this year. Not satisfied by the computerized systems available on the market, [Lucas] decided to build on last year’s project. To save a bit of cash, he built the setup around Parallax’s low-cost SX28 proto board. The system is capable of controlling 102 channels, with 8-bit dimming. 6 boards control 7 channels each and are communicated to through a serial protocol (reducing the whole setup to only 36 feet of wiring).

More importantly, he’s teamed up with 3 other neighbors who also share a passion for outdoor Christmas lighting and they’ve put together the Christmas Tour of Lights. Money raised from all donations goes directly to the St. Jude Children’s Reasearch Hospital in Memphis, Tennessee.
