Atari Punk Console
Yet another Atari Punk Console circuit implementation. Original hardware was made by Forrest M. Mimms III in 80s.
This version based NE556 timer, packed with photoresistor, momentary pushbutton and shifted work range. All schematics and 2-sided layout are in Autodesk Eagle format. GERBER files are also available.
