# glow-linux: reconstructing Spacetronik Glow Three LED control

> glow-linux reconstructs the Spacetronik Glow Three 27V LED controller's USB serial exchange from captured traffic. It documents the CH340 initialization sequence and AA 55 framed handshake, color and heartbeat messages, then uses pyusb for Linux lighting control and PipeWire screen capture for ambient color sync.
