We were surprised to see all of the Christmas gifts that revolved around Minecraft. Seems like there’s a lot of stuff for sale, but we still like the DIY spirit that comes with making your own. [Thacrudd] recently finished this project. It’s a wall lamp that looks like Minecraft’s diamond ore.
The enclosure is a wood box that used to contain chocolates. After studying the pixel art texture for the game’s diamond ore blocks he marked out the pattern and headed over to the scroll to rough them out before finishing with files and a rasp. Next came paint, which was sourced as a sample from the home store. This left him with one shade of gray, but the variations were easy to add by mixing it with white or black.
A strip of white LEDs gives the lamp its inner glow. The openings have been covered with blue acrylic which keep the dust out while providing the appropriate hue.
We’ve been following [CNLohr]’s process of creating an AVR-powered microscope slide running Linux and interfacing redstone circuits in Minecraft to real world electronic for a while now, but we’re really at a loss for words on how it works. Well, now there’s a video explaining everything you want to know about this amazingly complicated and overwrought thing.
The device is powered by an AVR microcontroller and Ethernet controller running [Fabrice Bellard]’s JSLinux in a browser. [CNLohr] added a few bits to JSLinux allowing him map the x86 IO ports emulated inside JSLinux to the AVR’s IO ports. This allows him to query the status – both analog and digital – using just a browser. Very cool, but [CNLohr] can also run his Minecraft server optimized for 8-bit devices on this microscope slide server to create a bridge between real electronics and redstone circuits.
In the video after the break, you can see [CNLohr]’s overly convoluted walk through of what’s going on with this microscope slide server. As a little bonus, you can also catch a glimpse of Hackaday at 00:20 in [CNLohr]’s most visited / new tab thingy in Firefox. We’re honored, really.

It hasn’t been a week since Minecraft for the Raspberry Pi has been released, and already we’re seeing some cool builds that bridge our analog world with Minecraft voxel land. [Martin] got his hands on the Raspi version of Minecraft and decided to take advantage of the API Mojang threw into the build by making a huge analog block clock that keeps real world time in the Minecraft universe.
Basically, [Martin] created a small Python script that draws the face and hands of a clock in a Minecraft world. The Minecraft API comes with neat functions such as drawCircle, and drawLine, so making a real clock face is as simple as getting the system time and doing a bit of trig.
After the break you can check out [Martin]’s Minecraft clock in action. If you’re running the Pi version of Minecraft, you can also get this running on your machine with the code on [Martin]’s git.

Mojang, the folks behind Minecraft, have officially released Minecraft: Pi Edition. This free version of the popular game is optimized to run on the Raspberry Pi hardware, and has an API that exposes the game’s internals to a variety of programming languages.
Mojang intends this release to be an educational tool for teaching and learning programming. Since the API provides instant feedback in the game, it could be an interesting way to make learning to code fun for people of all ages.
Having access to the API on a RPi also means that the game can be connected to the real world. For example, using Python and the RPi.GPIO, pins on the GPIO header can be used for output or input. This creates a slew of possible hacks that interface with the game.
Any ideas on what you’d like to do with Minecraft on a RPi? Let us know in the comments. Also, we coincidentally just printed a minecraft pick on our 3d printer. There’s a time lapse video of it after the break!

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.

This clock radio plays tunes from Minecraft and it’s decorated to look just like a creeper head. In the game mob heads are available as decoration and [Young_Maker] liked to spice up his virtual bedside table with a creeper head. But we think it looks just as good in its physical form.
The main part of the clock is an Arduino with a character LCD screen. A DS1307 real-time clock makes sure the device is accurate. We called this a clock radio in the title of the post, but it’s more of a clock MP3 player. The uMp3 board is used to play random music from the game. We would categorize the soundtrack as minimalism, which is a reasonable way to gently wake in the morning. But if time runs out the boom of an exploding creeper is played to make sure you’re not late for work.
We’ve embedded [Young_Maker’s] demo video after the jump.

The folks over at the Raspberry Pi Foundation often gets asked “does it run Minecraft?” Mojang, the team behind the block building game, has announced that they will be releasing Minecraft: Pi Edition. This port will be based off the Pocket Edition of the game, but with a revised set of features.
So what does this have to do with hacking? Mojang has announced that the Pi Edition will have “support for multiple programming languages.” There aren’t too many details about what this support will entail, but it looks to be aimed at teaching programming by using the world of Minecraft.
Hopefully, it will be possible to interface with the RPi’s expansion header to allow external devices to get data and create objects in the Minecraft world. There’s a lot of potential for hacking and learning programming skills.
The best part? It will be a completely free download. We’re looking forward to the launch.
