Dorkbot: February Edition

People doing strange things with electricity!

Along with the usual freewheeling chaos, the quick talks continue this month with Jim Snow, presenting "Designing and building the Mosaichord, an expressive music keyboard for just intonation.":
The Mosaichord is an expressive MIDI controller/synthesizer designed around a musical scale with 28 notes per octave, where the frequencies of all the notes are related to each other by whole number ratios, to enable better consonances and more varied dissonances than can be achieved in the 12-tone equal tempered scale. Internally, the Mosachord uses force-sensitive resistors under the keys and is controlled by a Teensy 4.0 microcontroller.

DorkbotPDX is a relaxed, informal show-and-tell for electronic artists, circuit designers, microcontroller programmers, retro computing enthusiasts, video game designers, digital archaeologists, and mod synth gearheads in Portland, Oregon.

Bring your electronic wonders, monsters, and works-in-progress for others to see, or come see what others have been working on! Whether it's code or circuits, electronic creativity of all sorts is welcome here.

Table space with power will be available for project show-and-tell; we'll have a table for drinks and snacks, feel free to contribute to the communal cache/BYOB. The Free cart is back, take or leave some components (don’t leave TOO much, if you have big stuff, maybe check the Discord/mailing list to see if anyone is interested in taking it first!)
