An Atari Punk Console (commonly shortened to APC) is a simple DIY noisemaker circuit that is relatively inexpensive and easy to build. The original circuit was called "Stepped Tone Generator" which was published in a Radio Shack booklet: "Engineer'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 The Atari 2600's. Kaustic Machines also added the -4db line level output to the circuit. The 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., 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 easily adaptable and has been configured in many ways and built into a wide variety of cases, from metal Ikea bowls to light bulbs. It has also been built into more tongue-in-cheek housings such as 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.
