The miniAtmegatron is a small 8-bit kit synth. It comprises of a DIY kit shield, Arduino Uno and enclosure. The audio engine based on the Atmegatron. If you’re a dab hand at soldering and want to dip your toes into the 8-bit ocean, this could be the synth for you! The package comes with instructions, PCB, all the electronic components, MIDI-hacked Arduino Uno and perspex enclosure. The shield kit and enclosure are also available separately.
- 0.5 – 1 hour build time, depending on experience
- Soldering experience recommended
- YouTube tutorial to help building
- Once built the shield slots into the top of the Arduino Uno
- The enclosure can then be assembled around it
- Powered by USB
- Audio via 3.5mm mono jack
- 8-bit monophonic MIDI synthesizer
- Unique Wavetable PWM Synthesis audio engine
- Controlled via 2 RGB LEDs, 5 buttons and 6 pots
- Instantly playable using inbuilt sequences or play button
- A huge number of Atmegatron features in 1 tiny device
- Save sound to memory for future use
- MIDI via USB port on Arduino
- Download the open source code from the downloads page
- Download the free Arduino development environment
- Upload the source code to the Arduino Uno and it’s ready to play!

The miniAtmegatron synthesis engine is based on the Atmegatron engine, with some features cut back or removed because of the simpler interface. Like the Atmegatron, the mini uses the PWM output of the Atmega328P processor.
