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

router

[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

arg-final-transmission

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.

Fubarino Contest: Minecraft, Zelda, Arduinos, And Hackaday

song

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!

Roboxotica (Barbot Festival in Vienna)

minecraft-cocktailbot--verse-publications

Just this past week was this year’s Roboexotica 2013! The annual event was the world’s first and is perhaps the finest festival of cocktail serving robotics out there!

Founded 15 years ago in San Francisco, Roboexotica brings together scientists, hackers, and artists from all around the world to build the most awesome drink dispensing technologies. It’s also an opportunity to discuss innovation, science fiction, and the world of robotics to come — after utilizing some of the robots of course!

The photo above is of one of the popular bots from this year — it’s called the Minecraft Cocktailbot. It dispenses the liquor out of its floppy drive, but only when you control it from inside a game of Minecraft!

More of the barbots present at Roboxotica can be found on the main site. We think our second favorite is the Bunnybot. It defecates peanuts — the mightiest of all  in pellet-form bar food.

Stick around after the break to see the Minecraft Cocktailbot in action!

Real-Life Raspi-Controlled Redstone Lamp

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.

Hackaday Links: October 20, 2013

Winter is coming. We’ve see those gloves in stores made specifically to work with your smartphone. [hardsoftlucid] isn’t buying it. He made his own version using… well, you just have to see it.

Here’s an eBookmark for a real book. What? Well, you know how an eReader does a great job of keeping your place between reading sessions? This is an electronic bookmark for paper books which uses LEDs to show you where you last left off reading. [via Adafruit]

[Thomas Brittain] wrote in to share his BLE Module and Pulse sensor updates. Both were featured in a recent Fail of the Week column and the latest iteration takes them from fail to functioning!

You may be able to get a free XMOS xCORE starter kit. The company is giving away 2500 of them. [Thanks Tony]

After learning about custom labels for microcontroller pinouts from [John Meachum] we’re happy to get one more helpful tip: a breadboard trench is a great place to hide axial decoupling capacitors.

A bit of cutting, solder, and configuring lets you turn a simple gamepad into a 4-controller interface for MAME.

Many of the Hackaday Staff are into Minecraft (between Let’s Play videos, running servers, and building computers in-game it’s a wonder we get anything done around here). We restrained ourselves by not making this video of a Restone circuit Blender animation on your desktop into a full front page feature. [via Reddit]
