==Intro==
A page dedicated to Lunetta Synthesis, the art of repurposing and perverting digital logic semiconductor chips into sound-producing devices. The techniques of Lunetta Synthesis were pioneered by sculptor and percussionist Stanley Lunetta in the 1970's. In 2014, [[NoiseHack|Noisebridge was honored to host]] a talk and demonstration by Stanley Lunetta himself.

This page is a work-in-progress. Feel free to add more info and links, but please try to keep it organized.
==General Tips==
For visual fun, use LED's wherever a schematic calls for diodes.
==Lunetta Oscillator==
The Lunetta Oscillator is the heart of Lunetta Synthesis. It's an oscillator based on a Schmitt Inverter.

Driving one Schmitt oscillator with another, through a diode, and using a switch as a trigger:

=== Tips ===
Most Lunetta syntesizers out there are raucous and chaotic. But sweet, gentle sounds are also possible.
* Tap the inverter output to obtain a loud, buzzy, digital square wave.
* Tap the inverter input to obtain a gentle, soft, analog triangular wave. That's the voltage presented by the capacitor as it charges/discharges.
