The author deployed mlb-led-scoreboard (a Raspberry Pi LED matrix scoreboard emulator) to Fly.io using Docker and RGBMatrixEmulator, which virtualizes hzeller's rpi-rgb-led-matrix library. The setup: Dockerfile + clone the repo + expose port 8888. Result: live MLB scoreboards accessible on demand via browser. Raw frame data streams over WebSocket, so cost is TBD. Timed with the World Baseball Classic, a WBC-specific instance runs at wbc.mlb-led-scoreboard.dev. The pattern generalizes to any rpi-rgb-led-matrix-based project.
