MousePods turns AirPods head tracking into mouse control on Linux

[Ranger]

AirPods can now control a computer mouse with head movements, even on Linux. Hackaday reports on MousePods, a Python app by Matteo Gaudioso that reads the motion sensors in AirPods on Linux without needing any Apple device

Head movements are turned into mouse movements, and the data can also be sent to opentrack for head tracking in flight and racing simulators. Gamers who fly or race in simulators will appreciate that

Existing open source tools could not talk to AirPods 3, so Matteo used Claude Code to run hundreds of probe tests. The breakthrough was discovering that Linux's default maximum packet size was too small to carry the sensor data, and raising it to the larger iOS default made the data appear

It is confirmed working only on AirPods 3 and AirPods Pro 2, and some features are experimental. The details are documented on GitHub

Turning earbuds into a head tracker is a clever way to reuse hardware people already own, and it could be a real help for accessibility. Sim racing and flight fans get cheap head tracking as a bonus. Finding a fix in a packet size setting shows how small details can block a whole project

Would you use your earbuds as a head tracker? And what other hidden features would you like to unlock in your gadgets?
