I’ve built an IoT device to let my family know when I’m in a meeting Introducing the IoT device Tabajara: “I’m in a meeting.” Do you work from home, and do people in your household always show up at the worst possible moments? Let me introduce the “I’m in Meeting” IoT device: it lights up at your office door whenever you turn on your webcam. It consists of an ESP32 with mDNS connected to Wi-Fi, using the Arduino framework for simplicity. The ESP32 exposes an HTTP server that handles a PATCH

Boxie - an always offline audio player for my 3 year old 2025-04-26 Channeling the spirit of the Gameboy Table of Contents At the end of July 2024, I embarked on a journey to learn electronics so I could build little gadgets for my son. In my introductory post I described a few electronic toys he uses frequently, including the Tonie Box, a device that plays audiobooks and has a huge library of content. The Tonie Box is great, until it isn't. As outlined in my original post, it has several de

A hot potato: The ESP32 chip, found in over a billion devices worldwide, contains undocumented vendor-specific commands that could potentially be misused to access device memory and manipulate Bluetooth functionality. Security experts emphasize that these commands are not directly accessible remotely without additional vulnerabilities and typically require physical access or already compromised firmware to exploit. An undocumented set of low-level commands has been discovered in the ESP32 micro

Update 3/9/25: After receiving concerns about the use of the term 'backdoor' to refer to these undocumented commands, we have updated our title and story. Our original story can be found here. The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains undocumented commands that could be leveraged for attacks. The undocumented commands allow spoofing of trusted devices, unauthorized data access, pivoting to other devices on the net

Building an open-source Wi-Fi MAC layer for the ESP32 The ESP32 is a low-cost microcontroller with Wi-Fi connectivity. Currently, the Wi-Fi MAC layer of the ESP32 is closed-source. This project aims to change that: by reverse engineering the hardware registers and software, we can build a networking stack that is open-source up to the hardware, instead of having to use the proprietary MAC layer. This will improve security auditability, open up the possibility for features not supported in the
