Real-Life Raspi-Controlled Redstone Lamp

Minecraft fanatics keep finding impressive ways to bring 8-bit components into the real world, and [Chris Tompson's] Redstone Lamp Replica is no exception. [Chris] wanted to extend his connection to the game world by not only replicating this block, but also by controlling its light-up effect when an in-game cube is lit.

The lamp is a product of the gang at Hive76, who worked together to develop a quick prototype using the Minecraft Python client pyCraft, an Arduino, a transistor and a temporary papercraft lamp mockup. Hive76 member [Kyle] pitched in to write the plugin for pyCraft, which listens for an on/off message and sets one of the RasPi’s GPIO pins accordingly. The hardware for the actual lamp was designed to smooth out the 8-bit quality into something a bit more precise. The result are laser-cut pieces of MDF with a zebra wood veneer laminated on top. The interior was finished off with amber cathedral glass and then the cube’s sides were glued together. The RasPi, PCB and LEDs fit inside, all snugly affixed together.

Swing over to the Hive76 project page for more details and links to the plugin, and see the video demonstration below. For another Minecraft-inspired real-life project, check out [Bill's] take on the BatBox.

Controlling a Raspberry Pi with real life redstone

We’ve seen computers built in Minecraft out of redstone, the game’s version of electricity, circuits, and digital logic. We’ve even seen a few redstone contraptions controlling real-world devices. [Angus]‘ build, though, takes things to a whole new level. He’s created a bridge between Minecraft circuits and their real life counterparts¬†using a Raspberry Pi.

[Angus]‘ build relies on a mod for Minecraft servers running as a Bukkit plugin. Blocks powered by redstone are labeled with an in-game sign, and messages regarding the state of a block are passed over the network using the MQTT protocol.

The hardware side of the build is a Raspberry Pi with a PiFace expansion board. With this setup, [Angus] can control LEDs on the PiFace by toggling Minecraft levers, or light up redstone lamps using the PiFace’s buttons.

If you’d like to try this out for yourself, you can grab the Bukkit plugin over on [Angus]‘s git. Check out the video of the real life redstone in action after the break.
