Lumetron translates the Earth's invisible magnetic rhythms into a choreographed field of reflections. Geomagnetic signals from an HMC5883L magnetometer drive suspended torsion elements, converting field variation into mirror rotation. An Arduino-based system reads XYZ vectors and maps them to servo movements that adjust string tension inside tubes, subtly steering each mirror. The device couples mechanical motion and optical projection so that magnetic change appears as oscillating light. Operating as both sculptural reconstruction and didactic prototype, it makes otherwise imperceptible forces tangible as spatial, temporal phenomena.

This project received the Technical Study High Pass Prize for Research investigating invisible planetary forces as responsive spatial experiences at the Architectural Association in June 2024.
