A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
A monophonic synthesizer based on an Atmel AVR microcontroller.
The first was the. It is a monophonic "virtual analog" synth based on an Atmel AT90S8535 microcontroller. The second version of AVRSYN uses ATMega16 and has a MIDI capabilities.
This synthesizer was reworked by "a-guy-called-krüe", which swapped the original atmega16 and 8MHz oscillator for an atmega32 and 16MHz oscillator.(See the photo above)
The last derivate I found is the "synth-diy" version. His version is modular, made on a perfboard. (Via) Links: - - - - -
