The SparkPunk Kit is a sound generator made in the spirit of the Atari Punk Console.
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.
The SparkPunk is a very simple synthesizer, using the somewhat conventional arrangement of oscillators that feed a filter. All you need to know to play this sound generator is to press the button, operate the control knobs, listen to the results, and adjust your music to how you want it. The SparkPunk is intended for you to explore and have fun! Some people are drawn to mellow, soothing sounds, while others prefer clangourous tones, and that’s fine, to each their own. With all of the controls, you should be able to explore both ends of the spectrum.
In addition, the SparkPunk is quite customizable as well. Any knob with a 0.25" inner diameter can be attached to the tops of each potentiometer, external speaker lines can be soldered into the board for a more permanent sound distrobution option, and photocells can be added to control the kit without actually touching it. There are plenty more optional modifications that can be added and played with.…more
