This effects box uses an Arduino to sample incoming audio at 40kHz with 8 bit precision, the audio data is then digitally pitch shifted and distorted to produce a wide variety of effects. To minimize the amount of computation required by the Arduino, I used a technique called granular synthesis to perform the audio processing. Essentially, as audio comes into the Arduino it gets cut up and stored as small (millisecond or microsecond sized) samples called “grains.” These grains are then individually manipulated and played back; they may be lengthened or shortened, stretched or compressed, played back in reverse, copied several times, or mixed with other grains.

This giant-size version of Operation from Brian of the Lansing Makers Network was an enormous hit at Maker Faire Detroit. The game is played just like the original and uses scaled up pieces and kitchen tongs as tweezers. An Arduino detects any false moves and reports them to a computer running a custom Processing sketch. In addition to keeping score, the sketch also keeps track of the the fastest times, peak usage, number of games played and any other information Brian, a self proclaimed data fanatic, could think of. I was a bit disappointed that the ‘scare you to death’ buzzer of the original was left out. Maybe he could work that in on the even larger version he’s building for next year?
