New Circuit Design Tutorial – Atari Punk Junk Console

I’m cleaning out my circuit designs and posting them here!

The first of many site updates and content is a favorite circuit of mine: The Atari Punk Junk Console.   After doing some research for school, I found an awesome video that brings vintage Atari 2600 sounds to the DIY world.

While the circuit is an good approximation of the 2600 sound, I decided to fork the design posted here by adding in some modulation and adapting it for line-level.


A complete circuit that sounds a lot more like Atari than the famous Atari Junk Console!

Check out my in-depth tutorial here!  I’ll be talking about the design process and break it down so that you’ll be able to use the circuit snippets to take this circuit to another level!
