It’s not a bazooka, but this altered instrument makes it look like the player is toking off of some type of weapon. [Kyle] wanted to take the already mysterious sounds produced by a didgeridoo then capture and alter them electronically.
The physical build of this project is nothing short of beautiful. He’s mounted several curved control boards to the outside of the instrument. The controls feature six push buttons, five toggle switches, and six potentiometers that interface with an Arduino. The sound is picked up by the device then sent along with the switch settings to a computer via Bluetooth. The computer then works its magic to create the wicked audio effects heard in the video after the break.
His article, linked above, includes several diagrams detailing the synthesis process. They’re a little beyond our understanding but if you know what’s going on, please share your insight in the comments.
