Light and Sound Cannon

Light and Sound Cannon

thingiverse

This design features a 32-inch long cannon with ample space for a Neopixel "fuse" and a 4-inch speaker. It's powered by any preferred board, but I've chosen a PI for its ease of use with audio. A hole is provided for a reed switch to trigger the cannon, which can be activated by embedding a magnet in a torch or sword.
