		==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.
		* For light-activated control, substitute photoresistors for resistors. Or, use a mercury switch like Stanley did in his gun-shaped device, in the photo above :)

		==Lunetta Oscillator==
		The Lunetta Oscillator is the heart of Lunetta Synthesis. It's an oscillator based on a Schmitt Inverter.

		[[File:Schmitt-osc1.gif]]

		[[File:Schmitt.gif]]

		=== Parts ===
		CD40106 Hex Schmitt.
		* 6 oscillators on a single chip!
		* Wide voltage supply (3V-15V), so you can drive with various batteries.
		* http://live.partlist.org/331/image/item/open/root/format=big

		=== Variations and Tips ===
		==== Intermodulation ====
		Drive one Schmitt oscillator with another, through a diode, and using a switch as a trigger:

		==== Gentle Sounds ====
		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-ish wave. That's the voltage presented by the capacitor as it charges/discharges.

		[[File:7414-oscillator-waveform-diagram.png]]

		==== Starvation ====
		Starve or overdrive the power supply to the chip for unexpected results.

		==== Amplification ====
		Use a cheap 3W '''PAM8403''' amplifier module to drive a speaker.
		* Make use of the PAM's stereo channels.
		* Overdrive the power supply of the PAM with a 9V battery for extra volume (but check the PAM chip for heat).
