Lit bulb, hotter comments
Banned Book Library in a Wi-Fi Smart Light Bulb
A rebel light bulb is hiding books, and the comments are loving the chaos
TLDR: A blogger built a Wi-Fi light bulb that secretly hosts digital books for anyone nearby to read, turning a household object into a stealth mini-library. Commenters loved the wild cyberpunk energy, but one sharp debate broke out over whether calling the books “banned” was accurate.
A blogger turned an ordinary Wi-Fi light bulb into a tiny secret library for books that have been pulled from schools and shelves, and the internet immediately treated it like peak sci-fi mischief. The idea is simple in plain English: if the bulb is powered on, people nearby can connect to it and read digital books. No giant server rack, no obvious box on a bench — just a lamp quietly serving up literature like a sneaky neighborhood book fairy. Commenters were delighted by the absurd genius of it, with one basically screaming, who even thinks of putting a web server in a light bulb? Another was already ready to shop, dreaming of a future where you can buy a cheap bulb and make your own “light bulb library” at home.
But of course, the comments couldn’t stay wholesome for long. The biggest fight was over the word “banned.” One reader called that label “disingenuous,” arguing these books are not actually illegal to own in the United States, which turned a cool hack into a mini culture-war wording debate. Others skipped the semantics and went full cyberpunk, fantasizing about these always-on book hubs quietly appearing around town because bulbs “blend right in.” There was even a nostalgia detour to PirateBox, an older project for sharing files over local Wi-Fi, proving that to the comment section, this wasn’t just a gadget stunt — it was a rebellious sequel. The overall mood: half inspired, half pedantic, and fully entertained.
Key Points
- •Rick Osgood built a project called Banned Book Library that uses a Wi-Fi smart light bulb as an open access point and web server for digital books.
- •The article presents the bulb as a low-cost, inconspicuous way to distribute material locally while the light is powered on.
- •Osgood says the project idea was influenced by Ben Brown’s short story *Library*, which features preservation of useful digital materials.
- •A local DEFCON meetup recommendation led Osgood to investigate Tasmota, an open-source firmware for locally controlled smart devices.
- •Osgood considered modifying Tasmota for the project, expected to encounter ESP32-based hardware, but instead found preinstalled Tasmota light bulbs sold commercially.
