This is a work-in-progress project, so somethings may change!

Pico Bluetoothbrush

The idea of this project is to create a Raspberry Pi Pico powered toothbrush. The Pico will be powered by a 3.7v LiPo battery, and will be connected to a motor driver board, which will drive a small DC motor. The motor will be connected to a small toothbrush head, and will be used to brush teeth.

There is a small display to show the time remaining, and a button to start the brushing cycle. The toothbush will contain a wireless charger, and in an internal lipo battery. The Pico W will run MicroPython and report the brushing time to a local MQTT server. It can also report data via bluetooth.

The screen

The screen is 128x32 pixels, black and white OLED. It is connected to the Pico via I2C. The screen is used to display the time remaining, and the bluetooth status. The screen model is SSD1306.

The (work in progress) microPython code is available on github
