LUMA is a pocket-sized ESP32 robot with a 1.8 inch TFT face. Two touch pads on the back switch between expressive eyes, the time, the weather and a calendar. Built by hand, printed at home, designed to sit quietly on your desk and look up when you tap it.
About
LUMA started as a weekend tinker and turned into a real desk friend. The eyes blink, dart around and react when you touch the top of its head. A second touch swaps the face for a clock, a weather card pulled from OpenWeatherMap, or a clean monthly calendar. No app, no setup wizard, just a tiny robot that does one thing well and looks good doing it.
