README.mdSnackboard µX - A DIY audio mixer for deej
Description
The Snackboard µX (mix/myx) is a PCB to control application volumes on Linux/Windows using deej. It is powered by an Arduino Micro over USB and utilises 6 sliders to control the audio volume of the software configured in deej. The microcontroller reads the current state via a 10bit ADC and sends a value of 0-1023 to the PC and deej via serial.
The goal of this build was to create a mixer without any need for a 3D-printer, mill or any kind of casing. It takes advantage of the fact, that most PCB manufacturers only ship 5 prototype board minimum and uses one of them for part assembly and another for a faceplate. All the tracks for connecting parts are routed on the bottom copper layer, so the front paste and silk layers stay clean.

Questions
How big is the Snackboard PCB?
It measures 222 × 156 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snackboard use?
26 parts, built around the RSA0N1219A03. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Snackboard KiCad files?
From the Snackya/Snackboard-mix repository on GitHub, at the commit this page was made from: the board is Snackboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snackboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
