"Political Atmosphere" traces the invisible connections between flight turbulence, climate change and war. Flight data is captured by an antenna and sent to a controller. Felix asked me to visually display the flight data and correlate the measured flight density in the sky with the speed of a DC motor. This motor turned a gearbox which ultimately triggered a siren. The more planes in the sky, the more frequently the centerpiece of the exhibition - the deafening siren - is triggered.
The Code
The open source software dump1090 was used to translate the antenna data to json data. This data was then sent to an Electron UI. If there was a change in flight-density, the App emitted the data via a websocket. The controller was therefore able to set the speed of the DC-Motor by changing the pwm signal. This was done by using a double-h-bridge board.
