By Cristiana Yambo and Sebastian Boaz The easiest way to start circuit bending is “playing open circuits.” That’s where you open up an audio device and use your hands or alligator clips to mess with the board inside and see what it sounds like.
My previous tutorial shows how to construct a simple sheet metal “bridge,” which, in combination with an ice cube bucket and an olive jar, makes an effective pneumatic trough for collecting gas samples over water.
I’ve had color organs on the brain since the last installment of the circuit skills series, so I decided try my hand at a new incarnation of the basic 3-channel sound-to-light machine using high-power LEDs.
