What better way to translate audio signals into light patterns than with this DIY project from Electronicpeasant.com. Throwing a few parties at your house while your rents are in Tahiti? Build a bunch of these, throw on some jam band music and take some hallucinogens to pay tribute to the late great Albert Hoffman. Perhaps some of your friends could bring over their DIY E-bolas to turn the party into a real rave that’ll have the police there (partying with you) in hours (they were busy). With LEDs for lights, the color organ was designed for extended battery use and doesn’t burn too much power. After all, no one wants to change a battery whilst under the influence.
