SparkPunk Hookup Guide
Introduction
The SparkPunk kit is a sound generator in the spirit of the Atari Punk Console.
The Atari Punk Console is a circuit that was originally designed by Forrest M Mims III, originally called the Stepped Tone Generator (seen on Page 26 in his book Timer, OpAmp & Optoelectronic Circuits & Projects). It caught on with indie, lo-f, and noise musicians as a DIY project that can be played as a very simple synthesizer.
Rather than simply recreating the Atari Punk, the SparkPunk is a new design that springs from a similar foundation. It starts with a dual 555 timer IC, then adds a second tone source, sub-octaves, and a bandpass filter. With all of the knobs and switches, a lot of tonal variations are possible. As a through-hole kit, the SparkPunk can also be easily extended and modified, expanding the palette of tones even further.
This tutorial will guide you through the assembly, testing, and modification of the SparkPunk.
