San Francisco Programmer Cameron Paczek Transforms Ceiling into Real-Time Flight Path Projection Screen
San Francisco software engineer Cameron Paczek has captured the 1090 MHz ADS-B public signals from aircraft broadcasts using a low-cost RTL-SDR receiver in his home located beneath the flight path of SFO airport, projecting real-time flight paths onto his ceiling with a projector.
This DIY project, named Skylight, also integrates night sky elements such as constellations, satellites, and the ISS's position, using a Raspberry Pi to process data and display information like flight numbers, aircraft types, speeds, and destinations without the need for the internet. The project has been open-sourced on GitHub and offers a kit.
In market dynamics, aviation enthusiasts and DIY developers purchase low-cost local ADS-B tools and open-source projects, selling subscriptions that rely on commercial apps; event-driven open-source sharing and the convenience of the SFO location direct funds towards RTL-SDR hardware and the aviation visualization ecosystem, benefiting aviation geeks and educational projects while facing pressure from the paid barriers of traditional flight tracking apps.

Cameron Paczek has long participated in open-source projects as a software engineer. The Skylight project continues the tradition of the RTL-SDR community utilizing ADS-B public signals for DIY trackers since the 2010s, evolving from simple reception to ceiling projection mapping, reflecting the transition from data capture to immersive visualization.
In terms of capital, Paczek mobilizes community contributions and enthusiast funding through GitHub open-sourcing and skylightceiling.com kit sales, motivated by the joy of sharing and lowering entry barriers, strategically transforming a personal project into a community resource while showcasing the practicality of local signal processing.
Commercial platforms like FlightRadar24 rely on centralized data, while Skylight is currently transitioning aviation enthusiasm from cloud-based apps to local hardware and immersive projection experiences, utilizing public spectrum to create personalized sky maps.
Essentially, this represents a technological substitution: low-cost SDR and open-source software replace commercial tracking dependencies with local real-time projections, leveraging ADS-B free broadcast signals to reduce information acquisition costs, pushing aviation visualization from screens into physical spaces, and reconstructing personal-level aviation observation infrastructure.
