Programmable color LED array from Evil Mad Scientist Laboratories – Boing Boing Our evil pals over at Evil Mad Scientist Laboratories have a neat demo video of their Peggy 2 Light Emitting Pegboard kit that they've populated with red, green, blue, and white LEDs. One thing worth noting (and that we demo in the video) is that you can diffuse the big RGBW pixels into one continuous full-color display by placing a thin diffusing plastic layer above the LEDs-- it really works well. (The Peggy 2 just so happens to be the cover star of MAKE Vol. 18.)
The Embarrassingly Easy Case Mod The problem with basic electronics projects is that they have a very bad ratio of effort to result.
At first glance this project might seem like an overly complex and daunting task.
