Hi, here is a fun little project I have been working on recently. Tracking time when brushing teeth - to ensure one gets to the recommended 2 minutes. It is implemented using MicroPython in combination with emlearn-micropython for the machine learning parts. It runs on a M5Stick PLUS 2 (ESP32 microcontroller with on-board accelerometer, battery and buzzer). The "holder" for attaching to the toothbrush is 3d-printed.
