2026 project

campus rf spectrum visualizer

campus rf spectrum visualizer

overview

This project turns ambient campus wireless activity into real-time light art. The system samples spectrum data, transforms it into a visual representation, and renders the result continuously on a custom LED panel setup.

highlights

  • Captured live RF activity with an RTL-SDR pipeline running on Raspberry Pi.
  • Converted FFT output into color and motion mapped to a HUB75 LED matrix.
  • Built the display into a frosted enclosure for a smooth, gallery-style visual effect.
