Per Adafruit, a maker called That Project has built a fully offline Rubik's cube solver powered by an ESP32-S3 microcontroller. The device scans the cube with a built-in camera, detects colors using OpenCV, and guides you step-by-step through the solution on a two-inch LCD screen—all without needing a phone, cloud, or PC. It includes an LVGL interface for manual color corrections too.
