TL;DR
A hacker has modified a commercially available ESP32 smart bulb to act as a local web server hosting banned books. The device broadcasts a WiFi network allowing users to browse and access these books, raising concerns about digital censorship and DIY activism.
A hacker has transformed a commercially available ESP32 smart bulb into a WiFi server hosting banned books, enabling access through a local network. This development highlights the potential for DIY devices to bypass censorship and raises questions about digital activism and security.
The hack involves disassembling an IoT-enabled smart bulb to access its internal ESP32 chip, which is then repurposed as a web server hosting a small library of e-books. The device broadcasts a public WiFi network, prompting users to connect and browse content via a captive portal. Although the device’s storage is limited to approximately 4MB, it contains several e-books pulled from US school libraries, which have been removed due to censorship policies. The project aims to demonstrate how everyday IoT devices can be repurposed for activism or privacy-preserving activities, but it also raises concerns about misuse and security vulnerabilities. The creator has noted that the device remains functional as a smart bulb, providing ambient lighting, alongside hosting the library.
Implications for Digital Censorship and DIY Tech
This development underscores how accessible technology can be used to challenge censorship, enabling individuals to host and access banned content privately. It also highlights the potential for IoT devices to be repurposed for activism, but raises security and safety concerns about unregulated modifications of connected devices. The hack demonstrates the blurring line between consumer electronics and tools for digital resistance, which could influence future debates on digital rights and surveillance.

Rise of IoT Devices as Platforms for Censorship Bypass
Over recent years, the proliferation of IoT devices like smart bulbs, cameras, and home assistants has created new avenues for digital expression and activism. This particular hack builds on prior examples of repurposing IoT hardware for unconventional uses, such as hosting servers or community networks. The specific focus on hosting banned books stems from ongoing debates about censorship in US schools, where certain literature has been removed from curricula. The project exemplifies a broader trend of DIY tech communities exploring ways to circumvent restrictions and promote access to information, often through small, low-cost devices. The hack was first shared on online forums and has gained attention for its simplicity and potential implications.
“This demonstrates how easily consumer IoT devices can be turned into tools for digital activism or censorship resistance.”
