[Matteo Gaudioso] released MousePods , a Python tool which accesses the motion sensors in Apple AirPods on Linux, turning them into mouse input. No Apple host required. Doing this required reverse-engineering how the devices work and communicate, because it turns out the AirPods 3 do things differently than other models.

Everything runs in a single Linux app, no Apple host involved.

Head tracking with AirPods has been around for years. Apple uses the motion data for spatial audio and gesture detection, and there are a number of open source tools to access that data. But there was always a blind spot: no one could figure out how to talk to the AirPods 3.

[Matteo] enlisted the help of Claude Code in digging out what was different, and found Claude pretty useful for running hundreds of probes and tests to the AirPods to eventually tease out what was going on, among other things. The findings are nicely summarized here .…
