A Handheld Gaming PC With Steam Deck Vibes

November 17, 2024 by Bryan Cockfield 9 Comments

Since its inception, the Steam Deck has been a bit of a game changer in the PC gaming world. The goal of the handheld console was to make PC gaming as easy and straightforward as a walled-garden proprietary console like a Switch or Playstation but still allow for the more open gaming experience of a PC. At its core, though, it’s essentially a standard PC with the parts reorganized into handheld form, and there’s no reason any other small-form-factor PC can’t be made into a similar system. [CNCDan] has the skills and tools needed to do this and shows us how it’s done.

The build is based around a NUC, a small form factor computer that typically uses the same low-power mobile processors and graphics cards found in laptops but without the built-in battery or screen. This one has an AMD Ryzen 7 processor with Radeon graphics, making it reasonably high-performing for its size. After measuring out the dimensions of the small computer and preparing for other components like the battery, joysticks, buttons, and even a trackpad, it was time to create the case. Instead of turning to a 3D printer, this one is instead milled on a CNC machine. Something tells us that [CNCDan] prefers subtractive manufacturing in general.

With all the parts assembled in the case, the build turns into a faithful Steam Deck replica with a few bonuses, like an exposed Ethernet port and the knowledge that everything can easily be fixed since it was built from the ground up in the first place. The other great thing about builds like these is they don’t need an obscure NUC for the hardware; you can always grab your old Framework mainboard for handheld gaming instead. Reminded us of the NucDeck.

An adorable mini rack for NUCs, plus a 5-port switch.

A Mini NUC Rack For Your Desktop

September 1, 2024 by Kristina Panos 16 Comments

We (well, some of us) are complete suckers for things that are both much smaller and much larger than life. And if that thing actually does what its supposed to? Squee! So naturally, we rushed to bring you news of this mini NUC rack designed by [Jeremy Weatherford].

Inspiration comes from a lot of places, often times from stuff that lives on your desk. [Jeremy] had a pile of NUCs and thought they resembled a mini rack already, so why not build them one to live in? It was the perfect excuse to learn CAD, so off [Jeremy] went. Although this is a mini rack, the parts were too big to print. Another opportunity presented itself, and [Jeremy] tried out an online service to get the acrylic cut.

Assembly may have been fiddly with super glue all over the nice black acrylic, but [Jeremy] learned an important tip: excess glue can be removed with vegetable oil. Once it was built, he decided to make it into a control system lab and even found a perfect little five-port switch to top it off. The logo plate, of course, is the icing on this cake.

If you prefer your tower of mini-computers to be extruded, we covered a clever design from [Jay Doscher] back in May.

Robot Arm Gives Kids The Roller Coaster Ride Of Their Lives

August 10, 2024 by Dan Maloney 60 Comments

Unfortunately, [Dave Niewinski]’s kids are still too little to go on a real roller coaster. But they’re certainly big enough to be tossed around by this giant robot arm roller coaster simulator.

As to the question of why [Dave] has a Kuka KR 150 robot in his house, we prefer to leave that unasked and move forward. And apparently, this isn’t his first attempt at using the industrial robot as a motion simulator. That attempt revealed a few structural problems with the attachment between the rider’s chair and the robot’s wrist. After redesigning the frame with stouter metal and adding a small form-factor gaming PC and a curved monitor in front of the seat, [Dave] was ready to figure out how to make the arm simulate the motions of a roller coaster.

Now, if you ever thought the world would be a better place if only we had a roller coaster database complete with 4k 60 fps video captured from real coasters, you’re in luck. CoasterStats not only exists, but it also includes six-axis accelerometer data from real rides of coasters across Europe. That gave [Dave] the raw data he needed, but getting it translated into robot motions that simulate the feeling of the ride was a bit tricky. [Dave] goes into the physics of it all in the video below, but suffice it to say that the result is pretty cool.

More after the break.

ARM And X86 Team Up In No Compromise Cyberdeck

December 5, 2020 by Tom Nardi 19 Comments

Over the last couple of years the cyberdeck community has absolutely exploded. Among those who design and build these truly personal computers there are no hard rules, save perhaps making sure the final result looks as unconventional as possible. But one thing that’s remained fairly consistent is the fact that these machines are almost exclusively powered by the Raspberry Pi. Unfortunately, that means they often leave something to be desired in terms of raw performance.

But [MSG] had a different idea. His cyberdeck still has the customary Raspberry Pi inside, but it also has an i7 Intel NUC that can be fired up at the touch of a button. He says it’s the best of both worlds: an energy efficient ARM Linux platform for mobile experimentation, and a powerful x86 Windows box for ~~playing games~~ working from home. It’s the hacker equivalent of business in the front, party in the back.

With a KVM connected to the custom Planck 40% mechanical keyboard and seven inch LCD, [MSG] can switch between both systems on the fly. Assuming he’s got the juice anyway; while the Raspberry Pi 4 and LCD is able to run on a pair of 18650 batteries, the cyberdeck needs to be plugged in if he wants to use the power-hungry NUC. If he ditched the Pi he could potentially load up the case with enough batteries to get the Intel box spun up, but that would be getting a little too close to a conventional laptop.

The whole plurality theme doesn’t stop at the computing devices, either. In addition to the primary LCD, there’s also a 2.13 inch e-paper display and a retro-style LED matrix courtesy of a Pimoroni Micro Dot pHAT. With a little Python magic behind the scenes, [MSG] is able to display things like the system temperature, time, and battery percentage even when the LCD is powered down.

In a post on the aptly-named Cyberdeck Cafe, [MSG] talks about how seeing the VirtuScope built by [bootdsc] inspired him to start working towards his own personal deck, and where he hopes to take the idea from here. The unique USB expansion bay behind the screen holds particular promise, and it sounds like a few add-on modules are already in the works. But of course, it wouldn’t be a true cyberdeck if it wasn’t constantly being improved and redesigned. Come to think of it, that makes at least two rules to live by in this community.

Mini IMac G4 Made With NUC And 3D Printer

November 10, 2020 by Lewin Day 5 Comments

Apple’s computers have been well regarded over the years for their sharp design features. Of course, something that’s great can only be cuter and cooler if it’s made even smaller. In just that vein, [Gary Olson] whipped up a 54% scale iMac G4.

The iMac G4 was the futuristic-looking flatscreen model, and the direct successor to the original CRT-based iMac. Unlike other projects that run Raspberry Pis or simply fit iPads inside, [Gary] elected to go for a Hackintosh-based build. The system runs Mac OS X on a Intel NUC kitted out with a Core i3 CPU. While it’s not a genuine PowerPC, using OS X fits the proper G4 aesthetic. The build relies on 3D printed components, with the scale size largely chosen to suit the size of [Gary’s] printer and the Intel NUC motherboard. [Gary] goes into detail explaining what was required to get the paint finish right and how to make the hinges stiff but movable.

We’re always fans of a mini retro builds, even if the fact that iMacs are now retro means we’re showing our age. If you’ve got your own cute micro PC coming together in the ‘shop, be sure to drop us a line!

AMD Introduces New Ryzen Mini PCs To Challenge Intel

December 24, 2019 by Tom Nardi 55 Comments

For the majority of hacker and maker projects, the miniature computer of choice these last few years has been the Raspberry Pi. While the availability issues that seem to plague each new iteration of these extremely popular Single Board Computers (SBCs) can be annoying, they’ve otherwise proven to be an easy and economical way to perform relatively lightweight computational tasks. Depending on who you ask, the Pi 4 is even powerful enough for day-to-day desktop computing. Not bad for a device that consistently comes in under a $50 USD price point.

But we all know there are things that the Pi isn’t particularly well suited to. If your project needs a lot of computing power, or you’ve got some software that needs to run on an x86 processor, then you’re going to want to look elsewhere. One of the best options for such Raspberry Pi graduates has been the Intel Next Unit of Computing (NUC).

NUCs have the advantage of being “real” computers, with upgradable components and desktop-class processors. Naturally this means they’re a bit larger than the Raspberry Pi, but not so much as to be impractical. If you’re working on a large rover for example, the size and weight difference between the two will be negligible. The same could be said for small form-factor cluster projects; ten NUCs won’t take a whole lot more space than the same number of Pis.

Unfortunately, where the Intel NUCs have absolutely nothing on the Raspberry Pi is price: these miniature computers start around $250, and depending on options, can sail past the $1,000 mark. Part of this sharp increase in price is naturally the vastly improved hardware, but we also can’t ignore that the lack of any strong competition in this segment hasn’t given Intel much incentive to cut costs, either. When you’re the only game in town, you can charge what you want.

But that’s about to change. In a recent press release, AMD announced an “open ecosystem” that would enable manufacturers to build small form-factor computers using an embedded version of the company’s Ryzen processor. According to Rajneesh Gaur, General Manager of AMD’s Embedded Solutions division, the company felt the time was right to make a bigger push outside of their traditional server and desktop markets:

The demand for high performance computing isn’t limited to servers or desktop PCs. Embedded customers want access to small form factor PCs that can support open software standards, demanding workloads at the edge, and even display 4K content, all with embedded processors that have a planned availability of 10 years.
