Confetti Cannon

by christinadanton January 31, 2012

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.

Bits used: bargraph , fan, motion trigger, power

    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!

  3. 3

    To build the "cannon": Bandsaw wood blocks or collect 4 pre-cut blocks

  4. 4

    Fit a screen for the fan (to stop the confetti getting in)

  5. 5

    Tape the motion sensor in place.

  6. 6

    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.

  7. 7

    Bandsaw masonite base (one find pre-cut base). Fix everything to the base. Fix the fan to the blocks.
