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.

Advancing The State Of Cyberdeck Technology

December 24, 2019 by Tom Nardi 8 Comments

It’s somewhat rare to be able to witness the birth and subsequent evolution of a technology, at least on a short enough time scale to appreciate it, but right now we’re lucky enough to see it happening within the burgeoning community of cyberdeck builders. We’ve seen an absolute explosion of cyberdeck projects in the last year or so, but this latest entry from [Tinfoil_Haberdashery] truly pushes the state of the art forward. Short of actually transmitting your consciousness into the Matrix, we’re not sure how much closer you could get to William Gibson’s original vision.

The design is based around a split ergonomic keyboard, with an Intel NUC in the center and a 1920×1200 IPS panel on a tilting mount off to one side. Since the display started its life as a DSLR monitor it doesn’t have a touch panel, but those who’ve yet to master a mouse-free workflow will be happy to know there’s a touch pad built into the lid of the NUC. Thanks to a clever dovetail joint, the deck also separates in half if you want to put some more space between your hands, or just to make the whole thing slightly less intimidating while carrying it on your back through the Sprawl.

Power is provided by a custom 18650 battery pack running at 18 V that [Tinfoil_Haberdashery] (naturally) assembled with a homemade spot welder. He’s included both buck and boost converters so the cyberdeck can be powered with a wide array of voltages should he find himself in need of some juice in the field. To maximize battery life he’s also worked in a relay to cut power to the monitor when the NUC is sleeping, and there’s a physical master switch that can completely disconnect everything for long periods of inactivity.

The very first cyberdeck featured on Hackaday was built by [Tinfoil_Haberdashery], and we’re glad to see he’s not resting on his laurels. While that first deck was certainly impressive in its own right, this build takes inspiration from the incredible work we’ve seen from other hardware hackers and raises the bar on what’s possible from this dedicated community.

Hard Drive Data Recovery – Why Not DIY?

December 24, 2019 by Lewin Day 53 Comments

Hard drive failures can be tough to bear, particularly for the average person who doesn’t back up. When it comes to data recovery, there’s always those bleating from the sidelines that it’s a job that must be left to the professionals. However, this is Hackaday, not HireSomeoneADay, so [Matt]’s video on do-it-yourself hard drive repair is just what we like to see.

The video begins with plugging the non-functional drive into an external caddy, and using a microphone to listen to the sounds it makes. Upon analysis, [Matt] concludes that the drive is not spinning up, and suspects the heads may be stuck, causing the problem. When tapping the drive fails to unstick the heads, the next step is disassembly.

Despite the best advice from armchair commentators, this can be achieved at home without a clean room. [Matt] opens the drive carefully, and notes that the head is indeed stuck to the platter, instead of sitting in its home position. Using a screwdriver, the platters are rotated in their usual direction while gentle pressure is applied to pull the head away, being sure to use a light touch to avoid ripping the heads off entirely. With this done, the drive is reassembled and powered up. Amazingly, the repair is successful, and data is able to be recovered!

It’s important to note that this is a highly risky procedure, and not guaranteed to succeed. Truly valuable data should be left to the professionals, but if you’re skint or simply unbothered, it doesn’t hurt to have a go yourself. Be sure to avoid dust entering the drive, and take care not to touch the platters themselves. Of course, if you brick the device, you can always scavenge it for parts. Video after the break.
