Do you want a fun and easy-to-build circuit? Here’s the simple, but fun Atari Punk Console – with schematics and parts list. It’s a quick build, so you can easily build it during an evening.
It takes its name from the old Atari computers of the 80s because it makes similar sounds.
And after my (not-so-intense) research (I basically just read about it on Wikipedia), I’ve come to learn that the circuit was first published in a Radioshack magazine in 1980.
Here’s a short clip of me playing with the circuit I built:
This was the first really cool sound-creating circuit I ever built.
Before building this I had only built simple tone-generators. So the first time I hooked this baby up, I was playing with it for an hour – making everyone else in the makerspace crazy.
This circuit is perfect if you have built a couple of simple circuits before and want more interesting stuff.
Or if you’re just looking for something really cool to build.

Parts List
To build the Atari Punk Console, you need:
- A breadboard board to build it on
- Jumper wires
- Speaker
- 470 Ω resistor
- 10 nF capacitor
- 100 nF capacitor
- Two 555 timer chips
- Two 100k potentiometers
- Two 1 kΩ resistors
Note: If your speaker can handle 1.25W or more, then R5 is not necessary – you can connect the speaker directly to the output.
These are all standard components and pretty easy to get your hands on. Not sure where to get components? Check out my list of where to buy components and tools.
Description
This is a refreshing alternative to the theoretical circuits you see in many books.
The circuit uses two 555-timers.
The 555 Timer needs a few capacitors and resistors to set the tone or the pulse length.
By combining one that sets the frequency and one that sets the pulse length, you can create some crazy sounds.
Atari Punk Console Kit
You can easily find all the components yourself and build it on a breadboard like described above. But if you prefer an even more convenient way – you could get yourself an Atari Punk Console kit.
The advantage of the kit is that you get everything you need in one go. And it also has a nice casing to fit the circuit into.

Can we have a followup explanation of how that circuit works? Also, how would you boos the sound with an OpAmp?

Good suggestions. I can’t promise anything, but I’ll keep those in mind.

wonderful！thank you for your Explanation and patience，i have learned a lot

Many thanks for sharing.

I noticed that the 100 ohm gets really hot, as there’s too much DC current is being pulled through. Only AC should go to the speaker.
I’ll send you the email of the image to be modified, as I can’t upload the image.
Ronald Boucher says
What I mean is that the speaker needs to have AC coupling output from 2nd 555 timer pin 3 to speaker, not DC coupling.

Hey Ron,
Thanks! I appreciate your feedback. The output from the circuit should always be alternating, that’s why I skipped the coupling capacitor. And I like to keep these circuits as simple as possible so that beginners think “I could build that too!” – so no filtering either.
The idea of the 100-ohm resistor was to make it possible to use really low-watt speakers without destroying them. But I totally forgot to take into account the power dissipation of the resistor! So thanks a lot for pointing that out.
Those using speakers that can handle 1.25W or more can skip the resistor and connect the speaker directly for a simpler circuit. Or use Ron’s version which is the more “proper” way of doing it with coupling capacitor and filter.
Best,
Oyvind
