A paper cannon that propels confetti using a fan. The confetti activates a motion sensor that sets of a light underneath the cannon causing it to glow. This project was made in a littleBits workshop at RISD. Created by Daniel Chang & Christina Danton.
Videos and Recipes
Connect motion sensor to fan
To wire the circuit, connect these Bits in the following order: power > motion trigger > wire > fan. Please note that this is a simplified version of the confetti cannon pictured above. Feel free to experiment and add Bits to your liking!
To build the "cannon": Bandsaw wood blocks or collect 4 pre-cut blocks
Fit a screen for the fan (to stop the confetti getting in)
Tape the motion sensor in place.
Cut a piece of paper and fold to wrap around the fan, make a hole for the motion sensor, tape in place around the fan.
Bandsaw masonite base (one find pre-cut base). Fix everything to the base. Fix the fan to the blocks.
Turn it on and have a blast!
