Piano hack adds a visual dimension to music

A Maker and modder by the name of Capricorn1 has added a rockin’ visual dimension to his already impressive musical skills by using a piano’s MIDI output to drive Edison bulbs.

Capricorn1 hung the bulbs from a rod of electrical conduit pipe, while threading the wires to a DB25 connector. The lights were controlled by an Arduino Mega (ATmega1280), along with a custom shield and optocoupler to handle zero cross detection.

“The easiest way to turn a light bulb on and off from a microcontroller is using a solid state relay (SSR),” Capricorn1 noted.

Fortunately, the Maker happened to have a board from a different project laying around with 12 SSRs on it, in addition to the necessary resistors.

All of the electronic components were situated in a repurposed switch box, which controlled four modes: classic, velocity, scrolling, and automatic.

The Maker also used a small sampling of the Arduino MIDI Library, namely the note on/off functions and the control change function to handle his sustain pedal.
