August 28, 2010 by Chris
Found Electronics' Project 3 pieces is probably one of the more artistically inclined projects that I've seen. They combine the art of electronics, music and plants all into one piece. There's a lot of pictures and a good write-up that illustrate the purpose and goal of their project.

Blue LED Car Radio Mod

July 27, 2008 by Chris
If you're tired of the plain old white leds that provide the back light behind your dashboard, check out this project. It gives a quick look at how you can alter your stereo setup and replace the leds (blue leds look especially cool). It's a quick and easy job and likewise, the write-up is short and to the point.

DiscoLazer

July 1, 2008 by Chris
This project is as intuitive as it is easy to build. Need some disco lazers? No problem! Just strap them onto some old blown speakers and watch the light show (there's a little more to it than that).

LED Color Organ

May 24, 2008 by Chris
The LED Color Organ is another project that lights up LEDs in a new, cool & different way (using audio signals). The soldering job this guy did for space saving was just down-right crazy but it works. He has step by step photos, schematics and everything you'd need to build it.
