One of the coolest things about electronics is that you can make pretty much anything electronic. With MIDI, synths, triggering, software, etc the possibilities are endless. Case and point.
The Electronic Didgeridoo. From MAKE Mag via Popular Science.
Kyle Evans, a 24-year-old artist, bought his first didgeridoo in a small shop in Cairns, Australia, three years ago. The owner helped him pick out one of his handmade Aboriginal instruments, and after Evans taught himself to play, he decided to build an enhanced version: an electronically modified, Bluetooth-enhanced PVC pipe that cranks out didgeridoo-like sound with added digital flourishes.
He cut a length of PVC pipe to form the body of the instrument and then mounted several square sections of a larger-diameter pipe to the outside. These platforms hide the wiring for the Bluetooth board and the control knobs that let him tweak the instrument’s steady drone.
When Evans plays, he blows through a beeswax-coated mouthpiece on one end, as with a traditional didgeridoo, and a wireless microphone positioned inside the far end relays the sound to his computer, which outputs sound to a speaker. At the same time, he can adjust the knobs, wirelessly signaling his computer to modulate the notes.
