A hacker converted a cheap smart LED bulb into a functioning Minecraft server.

FULL STORY

A hardware enthusiast known as Vimpo has taken the phrase can it run Doom? to
a new level by managing to host a Minecraft server on a budget smart LED
bulb.

The project began with an AliExpress-purchased bulb powered by a BL602 RISC-V microcontroller, a tiny chip featuring a single 192 MHz core, 276KB of RAM,
and minimal I/O.

Despite such limited hardware, Vimpo successfully transformed the bulb into a fully functioning game server.

From light source to game host

The hardware hacker started by opening the bulbs casing and carefully
removing its microcontroller.

Wires were then soldered to its headers and linked to a USB-to-serial adapter to establish a stable communication interface.

This setup allowed Vimpo to control the bulb, turning it on and off before converting it into what he calls a system ready to host a Minecraft server.

Though the process looked more like tinkering with electronics than
traditional web hosting , it essentially mimicked the logic behind remote server configuration.

The software side of the project was where the real challenge lay.

Running a Minecraft server on such restricted hardware required a
stripped-down implementation called Ucraft.

Vimpo notes the binary size is approximately 46K bytes without authentication and 90K bytes with the authentication library.

Even under stress from ten players, the total memory use barely exceeded 70K bytes.

Those numbers may impress anyone familiar with typical game server hosting demands, yet Vimpo admits that Ucraft lacks most, if not all, features of the vanilla server.

While the servers performance wont replace professional Minecraft server hosting any time soon, the experiment shows how flexible embedded systems can be.

The smart bulb essentially became a miniature web hosting device, though its capabilities remain more of a novelty than a practical breakthrough.

Still, this joins a growing list of unconventional tech feats, from running ChatGPT-like AI models inside Minecraft to recreating the game using COBOL code.

Projects like Vimpos lightbulb server remind us that curiosity, not utility, often drives hardware innovation - in tech, there is a thin line between creativity and absurdity, and modern game server hosting can be reimagined at the smallest scale possible.

It may not light up the world of computing, but it certainly brightened the idea of what running Minecraft can mean.
