mie ring

A round circuit board 50 mm across that lights a lamp from inside: ten RGB pixels in a ring on top, and underneath an ESP32 that joins Home Assistant through ESPHome. The board was designed in a fully agentic workflow.

Four views of the mie ring on a sage surface: the top of the board with its ring of ten pixels, the underside with the ESP32 module, and below them the copper layout of each side, in red and in blue.
