Over at BuildBrighton, we’re working on putting together a make-your-own-MIDI-instrument workshop to teach people the core basics of MIDI messaging and how to send and receive MIDI commands. As part of the workshop, we’ll be providing all attendees with an Arduino shield with some buttons, LEDs, volume/pitch bend pot and more.
Using a mixture of press-n-peel blue and the cheap Chinese alternative, we’ve managed to toner transfer about 20 boards.
After a marathon etching session (about three hours!) here are no less than sixteen boards (the final three boards were still etching when this photo was taken)
