Your AirPods Are Now a Mouse - Hackster.io

TL;DR

MousePods is an innovative project that repurposes Apple’s AirPods into a hands-free mouse for Linux computers. Developed by Matteo Gaudioso, this open-source application utilizes the built-in motion sensors of AirPods 3 and AirPods Pro to translate head movements into cursor actions. Instead of maneuvering a traditional mouse, users can simply tilt or turn their heads to control the pointer on their screen.
