An incredible DIY project, via xwoe.net
As the number of my guitar pedals grew, the decision was clear to build a pedalboard. Then I thought, why not add some light, so I can see the knobs in the dark. And then I found out about those programmable LPD8806 strips with libraries for Arduino and Raspberry Pi. That was when things blew out of proportion… so now the result is a mixture of light organ and pedalboard. It can turn sound into light using pitch detection and sound volume with a little help from a Raspberry Pi. It features several animation modes and a Tuner, a visual metronome and more to come.
