Turned the Smart Bulb into a Digital Wi-Fi Library
Security expert Richard Osgood turned the smart light bulb into a standalone digital library that doesn’t require internet. Here are the details of this creative cyberpunk project.
Cyber security expert Richard Osgood has undertaken a remarkable project in the technology world by turning an ordinary smart light bulb into an independent digital library that does not require internet access. Modified with the ESP32C3 microcontroller and Tasmota software, the device was turned into a closed digital repository that offers e-book access to those around it via a local Wi-Fi network. Osgood, who lives in the USA, proved with this extraordinary “cyberpunk” project how a standard lighting tool can turn into a decentralized server for content sharing.
- The system can share documents over local Wi-Fi without needing an internet connection.
- 2 MB of the device’s total 4 MB internal memory is reserved for text-based works.
- The hardware offers a completely anonymous reading experience without requiring any user registration or cloud service.
- Updates can be made over-the-air (OTA) without the need for any cable connection.
How the Smart Bulb Was Technically Modified
The ESP32C3 microcontroller, which is at the center of the project, enables the device to work both as a lighting device and as a web server.
Although Osgood initially aimed to add a microSD card slot to increase storage capacity, he had to give up this idea due to the physical limitations of the device.
Instead, by optimizing the existing internal memory, a space was created to store dozens of works.
This project shows how hardware limitations can be overcome through creative software optimizations.
What are the Advantages of Using the System?
The biggest advantage of the system is that it works completely offline. When users connect to the Wi-Fi network broadcast by the bulb, they can directly access the book list via the browser. This formula creates a completely local and secure digital sharing network where individual data is not transferred to cloud servers.
This structure, designed especially for privacy-focused users, eliminates dependence on central servers.
Independent networks create a new area of freedom in digital content sharing.
Future Developments Planned
Richard Osgood states that the project in its current form is ideal for small-sized text documents.
It is obvious that a larger memory capacity will be required to store visual content. However, thanks to OTA (Over-the-Air) update support, the device’s software can be made more efficient in the future. This small “cyberpunk” library proves that smart home devices are not only limited to functionality, but can also turn into a digital information source.
