The next-generation of monitor technology is upon us, quadrupling the number pixels our monitors can manifest and placing a heavy burden on our beleaguered video cards. What does it take to put together a 4K-ready gaming PC? Let’s find out, with a little help from AMD.
What happens when you gut a pumpkin and replace its insides with heat-shrink tubing, solder, 128 LEDs, eight AA batteries, an Arduino board and clever programming? You get what self-proclaimed tinkerer Nathan Pryor calls “Pumpktris.” Over the years we’ve seen the classic puzzle game Tetris ported to some amazing things, but a piece of fruit? Just in time for Halloween, this high-tech spin on the jack-o’-lantern features a fully playable Tetris game controlled from the pumpkin’s joystick stem. Whether you’re a hardcore do-it-yourselfer, or a diehard Tetris fan hoping to top the system’s high score (9,800 points), you can build your very own Pumpktris. Of course, its creator estimates it’ll take around 12 hours or longer to build the custom LED matrix and joystem and carve up the gourd of your choice. If you’re up to the challenge, you can find a complete walkthrough of the project at the source link below. However, if you’d just like to see this quasi-organic gaming rig in action, check out the groovy video after the break.

If a seemingly infinitely programmable mini computer like the Raspberry Pi is just too… limiting, we’ve got good news: the Gertboard extender has started shipping. The $48 companion board reaching customers’ doorsteps converts analog to digital and back for Raspberry Pi fans developing home automation, robotics and just about anything else that needs a translation between the computing world and less intelligent objects. The one catch, as you’d sometimes expect from a homebrew project, is the need for some assembly — you’ll have to solder together Gert van Loo’s Arduino-controlled invention on your own. We imagine the DIY crowd won’t mind, though, as long as they can find the fast-selling Gertboard in the first place.

CSI: Miami might be out of production, but that doesn’t mean we’ll be deprived of casual eyewear flipping. Not if Ben Heck has a say in the matter, at least. His latest DIY project automatically swings a pair of clip-on sunglasses into view whenever it’s too sunny outside: a photocell attached to an AT Tiny microcontroller checks the light levels and, through an Arduino-based AVR MKII language, tells a rotor to spin the glasses into place. No one will be labeled a fashionista with the requisite battery pack strapped to their heads, but the construction doesn’t require CNC milling and won’t destroy a favorite frame. We’re only disappointed that the sunglasses won’t play The Who on command… yet.

Vizio’s Co-Star Google TV hub has been public knowledge for more than half of 2012, but it might as well have been a black box as far as its internals were concerned. It’s mostly been a mystery beyond the acknowledgment of a Marvell ARM chip inside. The teardown gurus at iFixit certainly weren’t content to let that riddle go unanswered. Their exploration of the box shows that Vizio is very much clinging to the initial Marvell vision of using a dual-core, 1.2GHz Armada 1500 to handle 1080p video at that $100 price — albeit with just 4GB of flash to store everything the Android OS demands. What may interest hobbyists is simply the accessibility of the set-top box: just about every board and component comes out easily, which could lead to some cheaper DIY surgery. The full parts list is waiting at the source if knowing how your Google TV box operates is as important as catching up on Netflix.

We’ve already deconstructed Samsung’s Galaxy Note 10.1 on a metaphorical level, and now it’s iFixit’s turn to go the literal route. The DIY repair outlet found the pen-friendly tablet to be one of its easier tablet teardowns in recent memory: just about everything inside that frame can be swapped out individually. It’s even possible to replace the relatively cheap glass that sits on top of the considerably pricier LCD, just in case the slate plummets face-first but leaves some chance at salvaging its screen. While largely coming back with good news, the investigation also explains Samsung’s decision to go with a modest 7,000mAh battery — stuffing all those components into a 0.35-inch thick frame doesn’t leave much room for the lithium-ion pack that gives them life. Still, if you’re itching to understand what defines a truly repairable tablet, or just want to get a peek at those Galaxy S III-derived roots, the full surgical procedure is available at the source.

While we’ve been fans of the MacBook Pro with Retina display, iFixit hasn’t been so keen — a company based around DIY repairs isn’t fond of a system where most components are glued or soldered into place. That hasn’t stopped the team from developing a repair manual for those who want to give maintenance a try. A total of 16 guides show us how to disassemble or remove those parts that stand a realistic chance of leaving the system unscathed. While that does include some key components, iFixit continues to fly some caution flags: getting to one part often requires taking apart others, and removing the battery carries the very real possibility of permanent damage. If you’d still prefer to upgrade the SSD yourself (when an option) than pay Apple more for a custom order, there’s now a helping hand for your thriftiness.

Believe it or not, there’s a potentially cheaper (and more customizable) way to get NVIDIA’s quad-core Tegra 3 into your life than to spring for a Nexus 7. Kontron is readying a rare Mini-ITX motherboard, the KTT30, that combines the ARM-based chip with expandable RAM and a trio of mini PCI Express slots for expansion like a micro SATA drive or a 3G modem. The external ports are more the kind you’d find on a do-it-yourself x86 PC, too: full-size HDMI, USB and even Ethernet make a show at the back. The only hurdles are an unusually throttled back 900MHz processor speed and, quite simply, the lack of release details. Kontron hasn’t promised more than a release “coming soon” — with much more complete Tegra 3 devices now hitting the $199 mark, though, we can’t see the KTT30 putting much strain on any budding hobbyist’s wallet.

Big PC companies are often seen as being at odds with the concept of custom-built computers: apart from letting us tick a few checkboxes before we order, they’d rather we not fiddle with the internals. Fujitsu is breaking the mold and embracing some of that DIY culture with its upcoming Hands-on Custom PC Assembly Service. The Japanese can take classes that teach them how to install their picks (from a limited range) of processors, hard drives and RAM. While the program doesn’t start completely from scratch — the motherboard is already installed — it takes would-be assemblers through many of the experiences of building their own PCs from the ground up. Builders can choose how many components, if they’re not quite so ambitious, and learn smart practices like wearing anti-static wristbands. While there won’t be as many unintentional jolts of electricity as the real deal, the courses should help PC owners feel comfortable working inside a computer — not to mention save Fujitsu a few technical support calls. The variable-price courses start in Japan on August 9th for multiple Esprimo desktops and a LifeBook portable. We can only hope that American PC vendors take a few hints and encourage everyone’s inner technician.

Who knew Lego characters had to be somewhere in a hurry? Adafruit did, as it just whipped up a minifig-sized train schedule. The invention mates one of Adafruit’s own 1-inch OLED boards with an Arduino Uno controlling the schedule behind the scenes. It looks to be a straightforward project for the DIY types, although the display is currently all show: the schedule doesn’t (yet) pair up with the train tracks to automatically let your minifigs know if their trip to the pirate spaceship castle has been delayed by ghosts. You can check the source link for the full instructions. Duplo builders, alas, are kept out of the loop.
