Triggerboy is an open-hardware electronic synchronization tool to assist in the creation of live music visuals. It is an application for the Arduino hardware platform that is intended to interface with the LittleSoundDJ sequencer for Game Boy handheld systems. It is a tempo/clock slave to the Game Boy and can run on-board audio analysis and FFT spectrum analysis. It uses this information to trigger the digital out pins on the Arduino in time with the music.
So far, Triggerboy has been employed during live performances by The Glowing Stars, Matthew Joseph Payne and Slime Girls to trigger circuit-bending of NES and Genesis consoles to create glitchy, 8-bit visuals. It has become a regular component in Matthew Joseph Payne's rig for live visual performance. I collaborated with Matt in the design of the unit and the development of the hardware, and wrote all of the software.
It is based on the open-source Arduinoboy code and schematic with heavy modifications.
