Glow Engine uses a laser like a slow-scan CRT
2 min read
The Glow Engine, built by AJRussell, uses a 405 nm laser to energize Strontium Aluminate phosphor, creating images through slow fluorescence instead of cathode rays. A gimbal motor with Field Oriented Control and an ESP32 drives the scanning. Scanning left-to-right takes about eight seconds per frame.
