Script those Christmas Lights
Ever want to have your Christmas lights rock out? Brian Peek has written a great article showing off how to animate your Christmas lights for Coding 4 Fun using some Phidget Relays, some code, and some electrical parts.
With enough time and effort, you'll be able to rock them out in sync with some music and annoy your entire neighborhood.
Update: Brian has put up a YouTube video of his project now!
