The '''Atari Punk Console''' (commonly shortened to '''APC''') is a popular circuit that utilizes two [[555]] timer IC]]sICs or a single 556 dual timer IC. The original circuit, called a "Sound Synthesizer", was published in a Radio Shack booklet: "Engineer's Notebook: Integrated Circuit Applications" in 1980<ref name="Engineea_Notebook_Integrated_Circuit_Applicationsenica">{{cite web |url=[http://www.jameco.com/jameco/pressroom/punk.html |title=Engineer's Notebook: Integrated Circuit Applications], |publisher=Jameco |accessdate=13 September 2014}}</ref> and later called "Stepped Tone Generator" in "Engineer's Mini-Notebook -– 555 Circuits" by its designer, [[https://en.wikipedia.org/wiki/Forrest_Mims Forrest M.

Atari Punk console is an astable square wave [[oscillator]] driving a monostable [[oscillator]] that creates a single (square) pulse. There are two controls, one for the frequency of the [[oscillator]] and one to control the volume. The controls are usually [[potentiometers]] but the circuit can also be controlled by light, temperature, pressure etc. by replacing a potentiometer with a suitable sensor (e.g., photo resistor for light sensitivity). Most of the time there is also a power switch (often a toggle switch) and a volume knob.
The circuit is a simple [[DIY]] noisemaker circuit that is relatively inexpensive and easy to build, easily adaptable and is configurable in many ways. It has been built into a wide variety of cases, from metal [[IKEA]] bowls to light bulbs, an old Atari mouse or joystick. Its flexibility has led to wide scale popularity among electronics enthusiasts. It is often suggested as a good circuit to build for beginners.▼
