Mark has been working on variations of this electric violin for a few months now at the Boston Fab Lab. For Friday’s Learn 2 Teach Project Exposition, he got it into a playable condition and demonstrated it to visitors at the South End Technology Center.

He used Open Office Draw to design the files, and then cut the wood on the Shopbot. He made one of the effects pedals in his array with an Arduino inside a laser cut acrylic box.
