The ATtiny Punk Console (short ATPC) is an experimental musical synthesizer kit designed around the ATtiny85 microprocessor. Once started as an 8-bit equivalent of the famous DIY entry-level Atari Punk Console, it has developed into a minimalistic but feature-rich synth box over the years. The latest edition of the ATtiny Punk Console now offers a choice of 10 synth algorithms at startup, 3x CV Inputs, a new housing made entirely from printed circuit boards and the option of powering the device with USB-C.

Further features:

• Open Source hard- and software
• 3x powered CV inputs with red mini jack sockets on the front panel to connect Keys, LFO or self-designed modules
• Gate input or output (defined by choosed algorithm) - protected against overvoltage/ negative input
• Body contacts parallel to the potentiometers
• Analog output and filter section
• 6.35 and 3.5mm jack sockets connected in parallel
  

On startup, you can select different sound synthesis algorithms, ranging from pure sine waves to chaotic noise. To achieve this, choose a combination with potentiometers 3 and 4 (see table on the underside of the synthesizer) and press and hold the trigger button for 3 seconds when switching on. Some of the algorithms can either synchronize with external gate or trigger events or send out pulses themselves.
Adjust the volume with the VOL knob and cut output highs with the low-pass filter labeled TONE.

Four potentiometers are used to set parameters that change the behavior of the respective synth. The values can be slightly bended with the body contacts in front of them. Three of those can be overwritten by external 5V Control Voltage (CV) sources when connected to the red jacks on the front panel. This red TRS jacks uses a special scheme to simultaneously provide 5V as a power source, which is depicted on the bottom site.



This video shows how to connect CV-devices to a former version of the synth. The functions of the ATBase now are fully integrated into ATPC and can be selected with mode "Bass Base" (1B):

The ATPC comes as a soldering kit or fully assembled.
The kit is easy to build, even for beginners at soldering and was probed and refined on many workshops over the years.
