Lisbon Finals started as a simple question: could a Raspberry Pi on a terrace automatically photograph every plane that flies overhead — and post it to Instagram without any human input?
The answer, after months of iteration, is yes. What began as a weekend project became a full autonomous monitoring station — tracking noise levels, flight routes, airline patterns and atmospheric data, 24 hours a day, from a Lisbon terrace facing the LPPT approach path.
A small radio receiver picks up the signals every commercial aircraft is required to broadcast — giving us the flight number, altitude, speed and exact position in real time. A microphone simultaneously measures the noise level on the terrace. The system only triggers when both conditions are true: a plane is close enough, and loud enough.
A 4K camera continuously streams footage of the approach path. Every frame is instantly rated by an intelligent scoring system — only shots where a plane is clearly and sharply visible make the cut. The best frame is then paired with live flight data and sent to an AI to write the caption.
The chosen photo is processed by an AI image enhancer that reconstructs fine detail at 4× the original resolution — about 15 minutes on the station's small onboard computer. It is then automatically scheduled, avoiding quiet hours at night (11pm–7am). Everything goes live on @lisbon.finals with the AI-written caption and flight data — no human involved.
The station is continuously evolving. New hardware and sensors are being integrated to capture even more — from vibration analysis and industrial-grade acoustics to live ATC communications and air quality monitoring.
An industrial-grade sound meter will replace the current microphone. The new sensor handles up to 130 dB without maxing out — capturing the full impact of a low-flying aircraft as real numbers, not just a ceiling.
Hardware · OrderedTwo motion sensors mounted on the terrace will detect the physical vibration caused by passing aircraft — the kind you feel in your chest but a microphone can't fully capture. A new dimension of impact, beyond sound.
Hardware · I²CTwo environmental sensors will measure fine particles and air pollutants over the terrace in real time — correlating each aircraft passage with a concrete air quality reading. A first for a private monitoring station in Lisbon.
Environmental · SGP30 · PMS5003A second radio receiver tuned to Lisbon tower's frequency will capture live communications between pilots and air traffic control — linking each aircraft to the exact instructions they received in real time.
