[Drygol] found himself with six Commodore 64’s in various states of disrepair. Because batch work is often more efficient, he detailed the process of restoring all of them in parallel in this one-, two-, three-part series.
The first step was to whiten the cases. Old cases turn yellow from the degradation of the fire retardant additives in the plastic. The proven method to fix this is with a paste called Retr0bright. [Drygol] used hair bleaching paste which is very similar. The cases came out nicely whitened from their treatment.
Next he repaired the keyboard PCB and whitened the keys as well. Drinking was involved, but it all came out okay. The circuit boards were cleaned and inspected. There were a few corroded spots, broken chips, and bad solder joints to be repaired. A few common mods were also installed.
In the final part of the series two of the C64s have SD cards installed into them. A few interesting fixes were done to repair broken plastics. Lastly the two worst cases were painted. In the end [Drygol] found himself with six perfectly working and attractive C64s. Who know’s what he’ll do with them, but we all know that was not the point.
Minecraft modding has become almost as popular as the block-based game itself, with tons of editors and tools available to create new kinds of blocks, mobs, and weapons. And now, with this mod framework that can talk to an Arduino, modders can build blocks that break out of the Minecraft world to control the real world.
While turning on a light from Minecraft is not exactly new, the way that MCreator for Arduino goes about it is pretty neat. MCreator is a no-code framework for building Minecraft mods, which allows modders to build new game capabilities with a drag and drop interface. The MCreator Arduino toolkit allows modders to build custom Minecraft blocks that can respond to in-game events and communicate with an Arduino over USB. Whatever an Arduino can do – light an LED, sense a button press – can be brought into the game. It’s all open-source and free for non-commercial use, which is perfect for the upcoming STEM-based summer camp season. We can think of some great projects that would really jazz up young hackers when presented through a Minecraft interface.

Minecraft has come a long way since [Notch] first thought up the idea that would eventually make him a billionaire. The game can be enjoyed on so many levels and become so engaging that grown adults who should know better spend far more time playing it than working on, say, their backlog of Hackaday posts. As if that weren’t bad enough, now Minecraft threatens to break out of screen with the ability to control a WiFi light bulb from within the game.
For those unfamiliar with Minecraft, it’s an open world game that allows players to interact with blocks of various materials. Players can build, destroy, explore and create landscapes and structures. An active modding community contributes everything from cosmetic texture packs to new block types with extended functionality. It was one of these mods that was leveraged to “break the fourth wall” in Minecraft. [giannoug] used the OpenComputers mod, which allows placement of programmable in-game computers with a full complement of peripherals, including an Internet connection. That allowed [giannoug] to send commands to his Brand X eBay WiFi light bulb, the protocol for which his friend [Thomas] had previously reverse engineered. Flip a switch in Minecraft and the real-world light bulb comes on instantly. Pretty cool.
We’ve seen quite a few builds where Minecraft blocks inspired real-world lamps, but this is a step beyond and might be a great way to get kids into programming using Minecraft. But it’s not the first time Minecraft has broken the fourth wall – check out this 2012 effort to build a microcontroller-based Minecraft server that can toggle pins from within the game.
