If guitar effects pedals aren’t really your thing, perhaps Evan Kale’s touchless MIDI controller will fit the bill.

Using an Arduino, along with a Colpitts oscillator and some other electronics, Kale has come up with a rather unique interface for his guitar. Instead of using a foot pedal, he put a strip of aluminum foil inside of a fingerless glove, then attached a homemade metal detector coil and circuit to the back.

This allows him to strum the guitar, then change the sound by moving his hand away and toward the strings as a MIDI input. Very clever, and as always, Kale outlines everything in his own zany video style!

You can find the code for this project here and check out the schematic on Imgur. On the other hand, if this looks slightly familiar, he uses the same type of circuit for this MIDI controller as the metal detector previously covered on our blog.
