Light Controlled Musical Instrument

Illumaphone Uses Light To Make Music

Move aside Theremin,  we have another crazy instrument that relies on its musicians to frantically wave their arms around to produce a beat. This is the Illumaphone.

[Bonnie Eisenman] recently took a course on Electronic Music, and for her final project she was allowed to basically do whatever she wanted — so she chose to create a custom musical instrument. It’s fairly simple on the hardware side, making use of coffee cups, an Arduino Uno, six photo-resistors, some alligator clips and a whole bunch of cardboard — but don’t let the lackluster parts list fool you, it actually works quite well for what it is!

Each coffee cup is a different note, and the amount of light that gets into the cup determines its volume and vibrato. It even auto-calibrates to the ambient light levels when it is first setup! The light level data is interpreted by the Arduino which then sends it to a laptop standing by, which uses a software called ChucK to synthesize the notes for output.
