Lumen is a small open-source hardware node designed to live next to your computer long-term. Instead of being a single-purpose tool, it’s meant to act as a persistent bridge between software and physical feedback — lights, UI, and sensors — that can evolve over time. The focus is on extensibility and long-running use, not one-off debugging or fixed workflows. Everything is open-source, from firmware to hardware.
