Using Lego Mindstorms Sensors With a Raspberry Pi
Dexter Industries has been playing around with the RPi lately, and hooked up a Mindstorms-compatible accelerometer/gyroscope to a RPi running Raspbian. They have a full tutorial showing how they did it.
Optical Tremolo: Extended Play
With this Optical Tremolo Box you are hearing are patterns of light, created by a spinning disk translated into rapid electrical fluctuations to produce a warbling audio effect. Audio enters the circuit via the input jack, passes through the variable resistor — the light-sensitive photocell — and outputs to the amplifier, creating the effect known as tremolo.
