Hacklet 33 – Minecraft Projects

Minecraft hit the PC gaming scene as an alpha release on May 17, 2009. Something about the open world, the crafting system, and the various modes of gameplay made it an instant hit. Since then Minecraft become one of the best selling video games of all time, inspiring thousands of hacks, mods, and projects. This week’s Hacklet highlights some of the best Minecraft projects on Hackaday.io!

clawWe start with [Toulon] and his MineCraft Sidecar Keypad. The Mystify Claw was originally designed as an alternative input device for First Person Shooter (FPS) games. It may look like a mouse, but the claw has no balls or lasers. It provides a 10 button “cradle” for the left hand. Some folks liked the claw, but for many it quickly became a dust collector. [Toulon] resurrected this old input device as an awesome Minecraft controller. He started by yanking all the old electronics, replacing the claw’s brain with the Teensy 2.0, a favorite of keyboard hackers everywhere. New buttons and a slew of new Teensy code made things perfect for mining.

rappiNext up is [Thomas] and his Raspberry Minecraft Server. The Raspberry Pi has long been a hacking platform for Minecraft. The official Raspberry Pi edition of Minecraft is easy to get running, and great for hours of fun. You can also run a Minecraft server on the Pi, which is exactly what [Thomas] is doing. He’s set his Raspberry Pi up with a WiFi dongle and a battery pack. With a bit of configuration, this allows the Pi to become the center of a wireless Lan party. On batteries, the Pi will run for about five hours of continuous gaming. Details for [Thomas’] project are a bit light right now, but that’s only because he just literally started documenting and uploading his project as we’re going to press. Give him a few days and he’ll have everything filled in!

gppk[GPPK] brings a bit of Minecraft into the real world with Full Size Wireless Redstone Lamp. Inspired by smaller models of the Minecraft redstone lamp, [GPPK] decided to build a life-sized version. “Life-sized” in this case is about 1 cubic meter. That’s a BIG lamp! [GPPK] designed the shell of the lamp in Sketchup, and cut the sides out using a gantry style CNC machine. The structure will be held together with 3D printed connectors, while a Raspberry Pi will provide the brains. Turning the lamp on will be as simple as turning on a switch in-game in Minecraft. [GPPK] has been a bit slow lately with updates on the project. If you know [GPPK] let ’em know that we’re anxiously awaiting some info!

pipyFinally, we have [Simon] and Raspberry Pi Python Controller. One of the best ways to get kids hooked on hacking and electronics is to show them how simple circuits can lead to big changes. What better way to do that than wiring up a simple push button controller for Minecraft? [Simon] used an Arduino paired to a Raspberry Pi with a serial over USB connection. Buttons wired to the Arduino are sent through the serial link to the Pi, where a python script fires off actions based on the serial data. [Simon] has tested his script with Mincraft Pi Edition, and is happy to report back that it works great.

Do you know what’s missing from this Hacklet? Your Minecraft project! It’s not too late though – upload your info to Hackaday.io, and we might just add it to our brand new Minecraft Projects List!

Well, it’s just about quitting time here in the Hackaday Mine. As long as the creepers don’t get us, we’ll be back next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Hackaday Links: November 9, 2014

After many years of searching, [Dan Wood] finally got his hands on something he’s wanted for the past twenty-two years: an Amiga 4000. No, it’s not the queen bee of Amiga land – that honor would fall to the 68060-equipped 4000T, but [Dan]’s 4000 is decked out. It has a 256MB RAM expansion, Ethernet, USB, and a Picasso IV graphics card that gives it better resolution and color depth than most modern laptops.

[Pistonpedal] has a fully automatic pneumatic can crusher that is far too cool to be wasted on a case of Keystone. A funnel at the top guides the cans in to be crushed one at a time and ejected into a garbage can underneath. Great for recycling.

Coming over from ‘normal’ programming into the world of embedded development? [AndreJ] has the AVR C Macro for you. It’s a great way to get away from all those ~=, |=, and &=s that don’t make any sense at all.

[CNLohr] has a reputation for running Minecraft servers on things that don’t make any sense at all. The latest build is a light up redstone ore block equipped with an ESP8266 WiFi chip.

Oh, the Hackaday overlords and underlings are in Munich for this little shindig we’re doing. If you in town for Electronica come on down. If you have a copy of Neil Young’s Trans, bring it to the party.

Russians blowing up capacitors! As we all know, electronics only work because of blue smoke. [kreosan] is releasing this blue smoke from a few hundred caps. Fun times, even if they are a large number of inert tube shields in their collection of caps.

[mayhugh1] over on the home model engine machinist forum has built an 18 cylinder radial engine. It’s based on the Hodgson 9-cylinder radial engine that has been around for a while. The crank case is machined from a 5″ diameter rod of aluminum. There’s a Picassa album of the engine being constructed as well.

[Richard] wanted a Minecraft server, but not just any Minecraft server; this one demanded a custom case. A grass block was the inspiration, acrylic the medium, and a quad-core Mini-ITX the guts of the project.

Halloween was last Friday, and as always the tip line filled up with costume builds. [Leif] built a Ghostbusters costume complete with Muon trap, [Jeff] printed out some steampunk post-apocolyptic goggles, and [Green Gentleman] made a death-a-corn, although we’re struggling to figure out why the last one isn’t called an acorn-‘o-lantern.

[Matthias Wandel], a.k.a. the woodgears.ca dude,  is well-known in certain circles for being a wizard of wood. One of the first projects that put him on the map was a pantorouter – a router to cut mortises and tenons. He’s going back to his roots and building a bigger version. This version uses models of routers that are available outside North America, and in the latest video [Matthias] has it dialed in very well.

The Open Source Remote Control was an entry for The Hackaday Prize that didn’t make the final cut. It’s now an indiegogo project, and has some really cool tech we can’t wait to see in mainstream RC transmitters.

Introducing the Hayes Smartmodem 1200. The era of the single station microcomputer…. is over. The Hayes Smartmodem offers advanced features like auto answer and auto dial. Now if we could only find an ‘RS-232 Computer.’

Have a 3D printer and an old router? How about controlling your printer with Octoprint? For some cases, it might be better than using a Raspberry Pi and OctoPi, but you won’t get a camera for streaming pics of your builds to the web.

Last year, [CNLohr] built a microscope slide Minecraft thing and in the process created the smallest Minecraft server ever. The record has now been bested with the Intel Edison. There’s a bit of work to install Java, but the performance is pretty good for one player. Bonus: Minecraft is a single threaded app, so you have another core for garbage collection.

Remember the Scribble pen, that showed just how gullible people are and how crappy tech journalism is? They’re back with a beta program. A mere $15 guarantees you a scribble pen for their beta program. I wouldn’t give these guys $15 of someone else’s money, but lucky for us [ch00f] bit the bullet. He’ll be updating everyone on the status of his fifteen dollars, I’m sure.

Hey, guess what will eventually be in the Hackaday store? Keycaps for your mechanical keyboard. Yes, we actually figured out a way to do this that makes sense and won’t lose money. Pick your favorite, or suggest new ones in the comments:


Running Minecraft On Two Routers


[CNLohr] is no stranger to running Minecraft on some weird hardware. Earlier, he built this Linux powered microscope slide… thing to toggle LEDs with redstone levers in Minecraft. Figuring if Minecraft could run on an AVR, he decided to try the same thing on a router, a TP-LINK TL-WR841N to be specific. Like the microscope slide running Linux, this proved to be an easy task. [CNLohr] had another router he could run Minecraft on, and this one could also punch wood. There really was only one thing for him to do.

Like the microscope slide and the wireless router, [CNLohr]’s CNC router is now running a Minecraft server. The phrase, “because it’s there” comes to mind. When connected to the CNC server, the player controls a snow golem (a snowman with a jack ‘o lantern head) with a carrot. Wherever the snow golem goes, the tool head follows, allowing him to carve objects in the world, and on a sheet of MDF secured in the CNC machine.

It’s certainly an odd build, but [CNLohr] was able to carve out a pixeley, blocky Hackaday logo with the snow golem controlled CNC machine. Code here, video below.

Hackaday Space: Final Transmission Minecraft Puzzles Explained


This is the last part in our round up of the ARG that we ran throughout April. Just in case you’ve had your head buried in a hole this last week, it was a month-long series of puzzles that lead up to the announcement of the frankly awesome Hackaday Prize. During the week we’ve covered Transmissions 1, 2 and 3 detailing how we put the puzzles together and the things that went wrong. For the final stage we wanted something a bit different. Throughout the ARG we had been inspired by the book Ready Player One, so in this stage we wanted a high score table that people could compete over.

Since we’d managed to get reasonably far ahead of ourselves during Transmission 3 we had just over a week to plan this round. We pitched some ideas around the office for video games we could make with high score tables. None of these really stuck and we soon realized we didn’t have the resources to get the graphic design work done for most games. Someone suggested that we try making a MUD themed around a space port with rescue for Major Tom being the last stage. This seemed like a great idea at first and I began work on it using the RanvierMUD framework. It soon became clear however that writing all the text for a full featured MUD is actually a massive endeavor and I frankly am not that great of a writer.

Learn the secrets and watch a video tour of the Minecraft world below.

Fubarino Contest: Minecraft, Zelda, Arduinos, And Hackaday


In a clever bit of pandering to the gamer crowd for the Fubarino Contest, [Laurens] has combined The Legend of Zelda, Minecraft, and an Arduino to create something really, really cool.

[Laurens] cobbled together an Arduino, MIDI connector, and LCD display that will read a MIDI keyboard and detect when one of the songs from Ocarina of Time/Majora’s Mask is played. The Arduino then plays back the song slower and longer, just like in the game.

Here’s where things get cool: Since [Laurens] has an Arduino that knows when an OoT/MM song is played, he can have the Sun Song control the lights, or the Song of Storms turn his sprinkler system on. He chose to pipe all these commands into Minecraft, where the Song of Healing gives some health to the Minecraft character, the Song of Storms controls the rain, and other awesome mashups of Zelda and Minecraft.

This project offers more than enough to stand on its own, but [Laurens] also added a Hackaday easter egg. When playing the letters HAD in ASCII on the keyboard, our favorite URL shows up on the Arduino and inside Minecraft.

Here’s an image gallery and the source code (dropbox, so don’t spam it) for [Laurens]’ awesome project.

This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
