The Atari Punk Console is a simple DIY noisemaker circuit that is relatively inexpensive and easy to build. Atari punk console is just a trendy name for a simple beeping thing. The original circuit was called "Stepped Tone Generator" which was published in a Radio Shack booklet: "Enginer's Notebook: Integrated Circuit Applications, 1980. After that the circuit featured in the "Engineer's Mini-Notebook - 555 Circuits" by Forrest M. Mims III (Siliconcepts, 1984). The circuit is designed by Forrest M. Mims III. The circuit has a 556 dual timer IC at its heart.

The Stepped Tone Generator was named Atari Punk Console (APC) by Kaustic Machines crew because of its square wave output similar to Atari's. Kaustic Machines also added the -4db line level output to the circuit. Original circuit was intended to drive a small 8 ohm speaker.

Atari Punk console is an astable oscillator (square wave) driving a monostable oscillator which creates a single (square) pulse. There are two controls. One for the frequency of the oscillator and one to control the length of the pulse. The controls are usually potentiometers but it can be controlled by light, temperature, pressure, etc. simply by replacing the potentiometers with a suitable sensor (e.g., photoresistor for light sensitivity).

The circuit is easily adaptable and has been configured in many ways and built into a wide variety of cases, from metal Ikea bowls to light bulbs. Its flexibility has led to wide scale popularity among electronics enthusiasts. It is often suggested as a good circuit to build for beginners.
