Abacusynth Hardware @adafruit @johnedgarpark #adafruit

This beautiful, inviting, playful synthesizer is the Abacusynth by Elias Jarzombek.

Abacusynth is a synthesizer inspired by an abacus, the ancient counting tool used all around the world. Just like an abacus is used to learn the fundamentals of math, the Abacusynth can be used to explore the building blocks of audio synthesis.

It exists in two forms, one digital and one physical, that are both based on the same primary interaction: placing and manipulating shapes on rods. The visual and tactile control makes it easy and fun to create rich timbres sounds without having to fiddle with lots of knobs and sliders.

For more on the process, check out my blog posts explaining the fabrication, spinners, electronics, and code.

The physical synth was created using the Electrosmith Daisy Seed board and DSP platform to read the encoder sensors and for synthesis and MIDI processing. For a free, software-only version, the Abacusynth is available as an Ableton Live plugin here.

Beautiful work!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
