About this item

  • Easy project for beginners!
  • Stronger bass frequencies and more steps than the original APC
  • 3 potentiometer controls - Frequency (VR2) and Pulse Width (VR3) contour the tone while the Volume control (VR1) sets your output just right
  • 2 Control Voltage (CV) inputs allows step sequencers and waveform generators to expand the sonic capabilities of the Atari Punk Console from drone to arpeggiated dynamism
  • Requires a 9V battery or a 2.1-2.5mm 9V center negative power supply of at least 50mA (not included)


An easy-to-build, all board-mounted APC! With more stepped tones and better bass response, the APC Handheld is a new take on a classic circuit! Originally designed by DIY electronics guru Forrest Mims III as the “Stepped Tone Generator,” the Atari Punk Console is one of the most famous and recognizable Lo-Fi synth circuits ever. Using a single 556 dual timer IC with minimal part count, the Atari Punk Console circuit is a solid, time-tested noise generator capable of outrageous square wave madness! Features: Easy build for beginners! Stronger bass frequencies and more steps than the original. 2 Control Voltage (CV) inputs allows step sequencers and waveform generators to expand the sonic capabilities of the Atari Punk Console from drone to arpeggiated dynamism. Use any variable voltage source from 0-Supply Voltage for some glitchy goodness! 3 potentiometer controls - Frequency (VR2) and Pulse Width (VR3) contour the tone while the Volume control (VR1) sets your output just right. 1/4 inch mono jacks. Requires a 9V battery or a 2.1-2.5mm 9V center negative power supply of at least 50mA (not included). A Boss-style or one-spot adapter will work fine. PCB size: 83x53mm Important note about the CV Input: Make sure the tip of your cable is positive voltage, not to exceed 10V DC, and the sleeve is grounded (this is normal CV polarity). Plugging reversed polarity CV into your CV input may damage your unit and void your warranty

This APC was my first time ever doing any DIY soldering of a synth. I was so certain, that I was going to have to learn from my mistakes on this guy, and I was pleasantly surprised to find out I did it right the first time. It fired up when I attached the 9v battery and powered it on. It actually worked! This is amazing! I am having so much fun tweaking it, getting some seriously insane sounds out of it!!! The instructions are very well laid out. So easy, a person like me can do it. This is the beginning of a new hobby for me. I have already ordered the Chaos Nand, and the Sequence 8, and the DSM.
