The $5 Picaxe Beatbox

Corticalcafe has posted a project for an audio record and repeat device using a Picaxe-08M microcontroller, piezo speaker, and a handful of resistors. The Beatbox uses LDRs shielded inside nuts to sense the input “drumbeats”! When powered up the LED indicator lights and the circuit senses about 5 seconds of input beats. After the maximum recording memory if filled, the LED extinguishes and the Beatbox loops the playback of the recorded beat.

Here are the links to the project code and schematic from the corticalcafe website.
