Because why not squeeze a little good old-fashioned shredding into even the day’s most mundane activities, David Neevel developed a way to use his guitar to write out an email. Using a Roland snyth guitar pickup, Neevel sends MIDI data into an optoisolator circuit, an Arduino, a relay board, and finally into the “brains” of an old keyboard, so that each note triggers a different keystroke rad!
