Recently, Cameron Paczek has created a new project called SkyLight, where art meets technical implementation by displaying a live view of aircraft flying overhead on your ceiling. SkyLight consists of a projector, Raspberry Pi 5, RTL-SDR dongle, and some custom software.

The Raspberry Pi 5 and RTL-SDR receive live ADS-B data from local aircraft, and the projector points up at the ceiling and displays the live locations of aircraft as they fly overhead, effectively giving you a simulated X-ray through your roof. The projections also include the sun, moon, bright stars and constellations, and live satellites. 

This project reminds us of a British Airways billboard in 2014 that used live ADS-B data to have a child on the screen point directly at incoming aircraft. We note that these SkyLight and billboard projects would not be possible without live ADS-B data, as ADS-B aggregation sites like ADSB-Exchange and Flightradar24 typically have a few-minute delay and require payment for their APIs.

Cameron aims to productize his idea into a ready-made kit and crowd-fund it in the near future. If you are interested, you can sign up for his notification mailing list over at skylightceiling.com.
