Aviation enthusiast uses Raspberry Pi and ADS-B radio to create viral real-time airport tracker — open-source 'Skylight' intercepts aircraft signals and projects flight paths onto your ceiling

Software engineer Cameron Paczek created Skylight, an open-source project using a Raspberry Pi 5 and ADS-B radio to track aircraft in real-time and project their flight paths onto your ceiling. Skylight captures ADS-B signals emitted by planes, decodes them, and displays details like model, altitude, and distance to destination on your ceiling. The project also recreates the sky with celestial bodies and live satellite tracking. Paczek plans to release a ready-made kit for Skylight to make it more accessible to those who are not tech-savvy.
