LEGO And Minecraft Team Up For Custom Gaming PC Case

There are probably few parents who haven’t watched their kids sitting on the floor, afloat on a sea of LEGO pieces and busily creating, and thought, “If only they could make a living at that.” But time goes on and kids grow up, and parents soon sing the same refrain as the kids sit transfixed by the virtual equivalent of LEGO: Minecraft.

Finding a way to monetize either LEGO or Minecraft is a bit difficult for the young enthusiast; combining both obsessions into a paying proposition would be a dream come true. [Mike Schropp] did it, and this Minecraft-themed LEGO computer case was the result. Intel wanted a LEGO case for their new NUC mini-PC motherboard, and as a sponsor of the Minefaire event, the case needed to be Minecraft themed.

[Mike] chose the block that any Enderman would choose: the basic grass block. Each of the ten cases he made for the show had about 1000 of the smallest LEGO pieces available, to recreate the texture of the grass block in all its faux 8-bit glory. The 4″ x 4″ (10cm x 10cm) 8th Gen NUC board was a great fit for the case, which included slots for ventilation and SD card access, plus pop-out covers to access the board’s ports. It’s not exactly a screamer, but playing Minecraft on a grass block made from LEGO bricks is probably worth the performance hit.

We’ve seen [Mike]’s work a time or two here, most recently with a full-scale LEGO rack-mount server. Our hats off to him for another fun and creative build, and for proving that you’re never too old to LEGO. Or Minecraft.

A Mobile Computer To Make William Gibson Jealous

The personal computers in science fiction books, movies, and games are way cooler than the dinky pieces of hardware we’re stuck with in the real world. Granted the modern laptop has a bit more style than the beige boxes of yesteryear, but they still aren’t half as l33t as the custom PowerBooks in Hackers. Luckily for those who dream of jacking into the Matrix, the average hacker now has access to the technology required to make a custom computer to whatever fanciful specifications they wish.

A perfect example is this “cyberdeck” created by [Tinfoil_Haberdashery]. Inspired by William Gibson’s Neuromancer, this wild-looking machine is more than just a cosplay prop or conversation piece. It packs in enough power to be a daily-driver computer, as well as some special features which make it well suited for field work.

The body of the cyberdeck is 3D printed, but as [Tinfoil_Haberdashery] doesn’t have a 3D printer big enough to do the whole thing in one piece he had to break it up into subsections. He added a dovetail pattern to the edges of each piece, which makes for much stronger joint than simply gluing it together. A worthwhile tip if you ever find yourself in need of printing something really big.

Raspberry Pi aficionados might be disappointed to see the Intel NUC motherboard inside; which features a 3.4 Ghz dual-core CPU, 8 GB of RAM, and a roomy 500 GB SSD in an incredibly small package. To keep everything running the machine can take up to twelve 18650 cells, giving it a maximum run-time of sixteen hours or so. There’s even a 12 V power jack so he can power a soldering iron and other low voltage gadgets off of the deck’s batteries in a pinch. The integrated charger can take anywhere from 6 to 30 V, which gives [Tinfoil_Haberdashery] the ability to charge up from a wide array of sources.

But perhaps the best feature of the cyberdeck is the display. It uses a Fat Shark Transformer, a five inch 720p display designed for FPV drone use, which can not only fold flat against the deck for storage, but can be removed and slipped into a pair of goggles. This gives the cyberdeck a head mounted display that looks like something straight out of the movies. It even supports 3D, if you’re willing to cut the resolution in half.

Things have come a long way in the world of DIY head mounted computer displays. Really makes you wonder what the dedicated hacker is going to be able to pull off in another 10 years or so.

Self-Driving R/C Car Uses An Intel NUC

Self-driving cars are something we are continually told will be the Next Big Thing. It’s nothing new, we’ve seen several decades of periodic demonstrations of the technology as it has evolved. Now we have real prototype cars on real roads rather than test tracks, and though they are billion-dollar research vehicles from organisations with deep pockets and a long view it is starting to seem that this is a technology we have a real chance of seeing at a consumer level.

A self-driving car may seem as though it is beyond the abilities of a Hackaday reader, but while it might be difficult to produce safe collision avoidance of a full-sized car on public roads it’s certainly not impossible to produce something with a little more modest capabilities. [Jaimyn Mayer] and [Kendrick Tan] have done just that, creating a self-driving R/C car that can follow a complex road pattern without human intervention.

Unexpectedly they have eschewed the many ARM-based boards as the brains of the unit, instead going for an Intel NUC mini-PC powered by a Core i5 as the brains of the unit. It’s powered by a laptop battery bank, and takes input from a webcam. Direction and throttle can be computed by the NUC and sent to an Arduino which handles the car control. There is also a radio control channel allowing the car to be switched from autonomous to human controlled to emergency stop modes.

They go into detail on the polarizing and neutral density filters they used with their webcam, something that may make interesting reading for anyone interested in machine vision. All their code is open source, and can be found linked from their write-up. Meanwhile the video below the break shows their machine on their test circuit, completing it with varying levels of success.

Hackaday Links: June 14, 2015

You know we’re running this gigantic contest to build hardware and send someone to space, right? We’re doing community voting right now. If you’re on Hackaday.io, head over there and pick the best project. We’re giving away t-shirts and $1000 gift cards to people who vote. The drawing for this round is next Friday.

MicroPython is a pretty interesting development in the area of interpreted languages running on microcontrollers. It’s Python, the BASIC of the modern era, and now it’s being funded by the ESA. Great news, there’s going to be a port to SPARC, and it looks like MicroPython is going to be in a few satellites.

[EloquentlyMawkishBunny]’s calculator stopped working on the morning of his AP Physics test. It was the ribbon cable for the display. What did he do? He grabbed some magnet wire and made it work. If I’m reading this right, he did this the day of his AP test. Wow.

[Will] has made a name for himself by building roller coasters in his backyard. He’s also worked on the ProtoPalette, and now he’s building a hackerspace in Concord, California.

[Josh] needed to drill some very large holes with his mill. He decided a hole saw was the easiest way to do this, but his hole saw has a hex shank. He ended up chopping the shank of a hole saw extension, basically turning it into a hex to round adapter.

Did you know the Arduino IDE on Raspbian is stuck at version 1.0.5? The newest version is 1.6.4, and there’s useful stuff like autosave in the IDE now. Amazing. [CRImier] got the latest Arduino IDE working on the Raspberry Pi 2. Yes, there’s an issue up but if for some reason you’re programming Arduinos on the Pi, you should probably do this yourself.

Oooohhhh, case modding. The Intel NUC is a pretty interesting platform for case modding; it’s small, and I shouldn’t have to remind anyone of all the cool case mods that were created when the Mini-ITX format gained popularity in the early ‘aughts. [Femke] got herself an Intel NUC, made a case, and the results are amazing. How’d she get that metal bowl? Metal spinning. Very cool.
