MIDI-Controlled Light Organ

MAKE subscriber Colin Mann of Los Angeles, CA, created a light organ that uses antique bulbs.

12 light bulbs correspond to the 12 notes in an octave (minus the octave note). The rectangular box unfolds to position the light bulbs vertically for display, while at the same time providing a platform for the keyboard in use. Playing a note on the keyboard directly via midi, or through the usb port illuminates the light bulb for a particular key. Releasing the note, releases the key. Pedal presses are also recognized and keep the bulb maintained. The bulbs can be controlled without a computer by using the front mounted midi port, or via computer which allows for remote control via midi or osc messages.

The maker has an instructable and the creation was featured in a music video.
