PIC32mx based drum machine running in jam mode

Matt posted an update on his drum machine with a new 32bit PIC and a new larger LCD we covered previously: My initial prototype was based on a fairly common PIC available in DIP format, the PIC24FJ64GA102 which has 64kb of flash and 8kb of RAM.  As I started to build up the firmware I quickly found myself […]

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 […]
