DIY master Vimpo posted a video on YouTube demonstrating his process of successfully running a Minecraft server on a cheap LED bulb:
He purchased a cheap bulb from AliExpress, then disassembled it to extract the built-in BL602 microcontroller (featuring a single-core RISC-V processor, 192MHz clock speed, 276KB RAM + 128KB storage). By soldering wires to connect a USB-to-serial adapter, he transformed the bulb into a “micro-host” that could be connected to a computer.
To adapt to the low-configuration hardware, he used the open-source solution Ucraft (binary file approximately 46KB/90KB), with memory usage dynamically changing based on the number of players (approximately 20KB-70KB with 10 players online). Ultimately, three players were able to connect, but this bulb server lacked most of the features found in a standard Minecraft server—in fact, it could be said to have almost none of them.
This modification verified the possibility of running a basic server on low-cost hardware, showcasing the innovative potential of hardware DIY.
