Standalone Rubik’s Cube Solver Built on ESP32-S3
Adafruit Blog
EDITOR BRIEF
That Project built a fully handheld Rubik’s Cube solver using an ESP32-S3. It scans the cube with a built-in camera, uses OpenCV to detect colors, lets you fix mistakes with a touch interface, and shows step-by-step guidance on a 2-inch screen without needing a phone, cloud, or PC.
INSIGHTS
This is a good example of combining hardware, computer vision, and a simple user interface in one project. If you’re learning, try building a smaller camera-based color detector first, then add screen output and manual correction.
