A while ago I made some pretty cool things and wanted to share them with anyone who might want to recreate it for their own purposes. Two were light control boxes for a small, not too expensive band light kit, the other was a USB guitar for a clone of Guitar Hero called Frets on Fire. I made directions and notes on how I made these on Instructables. The first was a dimmer based three light controller I call the Band Blinder, the second is a sound driven power trigger I call the Band Blinker, and the third is the USB guitar.
And by the way, the guitar is red in real life. It's not pink :P.
