Adjust the fader by hand and your system volume follows. Change volume in software and the fader moves on its own to match. It works both ways, all the time, automatically.
This is a single-fader motorized volume controller for Linux (PipeWire/PulseAudio), built around a Raspberry Pi Pico 2. Plug it in via USB, and it just works — no configuration needed.
How It Works
A motorized linear fader (the kind you'd find on a mixing console) is connected to a Raspberry Pi Pico 2 via a small motor driver board. A daemon running on your Linux PC keeps the fader position and your system volume permanently in sync:
You move the fader → volume changes in software
Software changes volume (media keys, apps, whatever) → the fader glides to the new position on its own
The firmware auto-calibrates to your specific hardware on first boot — no tuning required.
The enclosure is a GEN2 drawer that slides directly into the GEN2 modular desk system with no screws or custom mounting.
What You Need
Electronics
Bourns PSL60 motorized linear fader — 10k, 60mm travel, with motor
JST-XH 2.54mm connectors and cables
JST-PH 2mm connectors and cables
Hardware
M3 screws and heat-set inserts
GEN2 parts to print separately
185-2W-1H Case — use the April 2026 or later version (has the back wall hole)
Build Time and Difficulty
Expect 2–4 hours for a first build. You will need basic soldering skills and a Linux machine to run the host daemon. Firmware flashing requires cargo and picotool — the full instructions are in the documentation.
