Celebrating 10 years of SGMK (Swiss Mechatronic Art Society), lifepatch is organising a small workshop with a special modul, Micronoise – Jubilee. It was sent to us as a remote session for celebrating their birthday. Lifepatch’s post in Indonesian can be seen [[>>here<<]].
Atari Punk Console is one of my all time favorite synth. It’s a combination of two 555 timer chip (or IC 556) oscillator which produced 2 layers of square wave sounds. Atari Punk Console (APC) is a name given by Kaustic Machines crew because of the “low-fi” sound it produced is similar to the games from Atari Consoles in the 80’s, with square wave similar from Atari 2600. In this tutorial I’m giving schematic, EagleCad files and PCB design of APC using NE556 Integrated Circuit. Check out the video above to hear how it sounds :)

From the simple oscillator using NE555 I posted before, we can make different wave signals. The simple oscillator produced a square wave signal in which the changes between 0 to 1 goes in an instant. To produce a different wave signal, we can put a passive filters to ‘shape’ the signal output. Passive filter consists a composition of Resistors and Capacitors in which they shave and cut the square wave output. In this post, I put a together an oscillator based on MK555 schematic which combine Square, Integrator, Triangle, Sine (S I T S – to make it easier :D) in one oscillator with various different passive filter.
