Skylight

Skylight is an open-source project that turns a ceiling into a real-time visual map of aircraft passing overhead. It decodes ADS-B signals from an RTL-SDR radio or can use a web API for testing without radio hardware. The system renders planes onto a ceiling-pointed projector so nearby aircraft appear to move across the room as they move through the sky. It also adds a live sky layer with the sun, moon, stars, constellations, planets, satellites, and the ISS based on the user’s location and time. A phone control panel lets users adjust rotation, themes, palettes, filters, and sky settings over a local network. Its main value is combining flight tracking, astronomy, projection art, and Raspberry Pi hardware into a practical interactive installation.
