Hardware Hacking: Extracting Firmware from an Electric Toothbrush with Raspberry Pi and PiFex
2025-04-06
This article details a hardware reverse engineering project targeting an electric toothbrush, using a Raspberry Pi and PiFex board. The author meticulously explains how to create a Raspberry Pi image with PiGen, pre-loaded with necessary software and configured for peripherals like UART, SPI, and I2C. OpenOCD WebUI and Jupyter Notebooks are leveraged for firmware extraction and hardware-level debugging. The process involves modifying configuration files, installing dependencies, and accessing the Pi via USB-to-Serial and USB-to-Ethernet gadgets. The ultimate goal is to extract the toothbrush's firmware and achieve hardware-level debugging.
