Cyberdeck Build Gets Closer To Regular Laptop Than Most

Image
Cyberdecks are typically reminiscent of weird computers in futuristic sci-fi films, moreso than the computers of today. The cool thing about cyberdecks, though, is you get to build them however you like. [WillTechBuilds] has put together a deck of his own that diverges from cyberdeck norms and ends up closer to something you might have bought off the shelf at Best Buy. For a start, the build eschews the typical Raspberry Pi or other single-board computer that normally lives at the heart of a cyberdeck. In its place is a motherboard harvested from a GMKTec NucBox G5. It runs the Intel N97 CPU. It’s an x86 processor that’s roughly equivalent in power to an i5 from 10 years ago, but it only sips 12 watts. The compact motherboard is installed in a compact 3D-printed case along with a porbable USB-C battery pack, a small widescreen LCD, and a Lenovo ThinkPad trackpoint keyboard. This latter design choice, along with the x86 chip, is what gives this build so much of a laptop feel. There’s...

Growing Aluminium-Copper Alloy Crystals Using Hydrogen

Image
Having molten aluminium interact with atmospheric water forms a source of hydrogen which can be rather problematic if you’re trying to cast aluminium parts. As the molten metal cools down, the dissolved hydrogen is forced out, creating bubbles and other flaws that make aluminium foundries rather upset. While you can inject inert gases to solve the problem, you can also lean into this issue to make some rather fascinating aluminium crystals and geodes , as [Electron Impressions] recently did. The key here is to use a eutectic Al-Cu alloy at around 45% Cu by weight, as this alloy readily forms large crystals as it cools down. With hydrogen injected into the molten metal, this hydrogen forms large bubbles inside the cooling metal with crystals clearly visible. A way to create proper geodes involves very slow cooling and pouring off the still molten metal before the eutectic point is reached. As can be seen in this video, this creates a rather impressive looking geode after it’s been sm...

Making the Most Pick-Proof Lock Yet

(Credit: Works By Design, YouTube) Throughout the centuries the art of lock-making and lock-picking have been trapped in a constant struggle, with basic lock designs being replaced by ever more complex ones that seek to thwart any lockpicking attempts, as well as less gentle approaches. When it comes to the very common pin-and-tumbler lock design, the main issue here is that the keyway also provides direct access to the lock’s mechanism. This led [Works By Design] to brainstorm a lock design in which the keyway is hidden . The ingenious part here is that because the actual key is rotated away after insertion, there is no clear path to the pins. This did require some creative thinking to have a somewhat traditional style key as well as a way to turn the internal mechanism so that the key would be pressed against the pins. Here inspiration was drawn from the switchable magnet mechanism as seen with ...

Vintage Chyron TV Hardware? Of course It Runs NetBSD

Image
Perhaps at this point, getting NetBSD running on an obscure piece of hardware is a dog-bites-man story, and not worth reporting– their motto, after all, is “Of course it runs NetBSD”. So, the fact that [RetroComputingRanch] has got NetBSD running on a vintage Chyron Maxine broadcast computer is perhaps remarkable only for the fact that few people have even heard of Chyron before. He’s already done a series of videos in which they explore this odd, old computer, which is powered by a Motorola 68040 on a VME bus and was once used to generate digital overlays– text and the like– on broadcast TV. NetBSD does have a port for the Motorolla VME SBCs, so he was able to vibe it onto the specific vme168 board that the Chyron is based on. It happens off screen, but apparently it was AI agent work that went into condensing the documentation for this machine as well as getting the NetBSD port set up. That’s a bit ironic, since NetBSD would never allow that in its commits.  Again, the Chyron...

Quirky Electric Car Rides the Rails

Image
We wouldn’t be surprised if you’d never seen the Spira before. The lightweight three-wheel vehicle is closer to a go-kart than a traditional car, and that’s before you even get to the foam body panels. But even the most niche of products enjoys a certain fandom, and [Matt Spears] certainly seems to love working on his Spira. His latest video documents the new modifications he’s made to the car in an effort to ride it on abandoned railroad tracks in the western United States . His first attempt at riding the rails worked pretty well but he hit an obstruction at high speed which destroyed his front axle and damaged a few other parts on the vehicle, which gave him a perfect excuse to make some upgrades. He swapped the old rear axle out with one from a go-kart, complete with custom wheels and a new braking system. The drivetrain received an upgrade with a 5 kW electric motor, and although [Matt] planned on casting new wheels for the higher speeds, the chemicals he needed didn’t arrive in...

Modded Server PSU Provides Plenty of Current

Image
Most makers find themselves in need of a benchtop power supply at some point or another. Basic models can be had relatively cheaply, but as your current demands go higher, so does the price. [Danilo Larizza] has figured out an alternative solution— repurposing old server hardware to do the job instead. The build is based around an HP Common Slot (CS) server power supply. They can be readily had for well under $50 if you know where to look. Even better, they can deliver over 50 amps at 12 volts, which happens to be a very useful voltage indeed. All you need to do is some minor mods. A jumper on a couple of pins will get the power supply running, and with the addition of some terminals for your hook-up leads, you’re ready to go. As a hot-swappable single unit, the power supply is already outfitted with a ventilation fan to keep everything cool. If so desired, you can even make some further mods to bump output voltage a little ways past 13 or 14 volts if you’d like to use them for cert...

Hackaday Links: April 19, 2026

Image
We’ll start things off this week with a story that’s developing more than 25 billion kilometers from Earth — on Friday, NASA announced that the command had been sent to shut down Voyager 1’s Low-energy Charged Particles (LECP) instrument . As the power produced by the spacecraft’s aging radioisotope thermoelectric generator (RTG) continues to dwindle, engineers at the Jet Propulsion Laboratory have been systematically turning off various systems to extend the mission for as long as possible. It’s believed that deactivating LECP should buy them another year, during which engineers hope to implement a more ambitious power-saving routine. If this sounds a bit familiar, you’re probably thinking of Voyager 2. The plug was pulled on its LECP instrument back in March of 2025 . The JPL engineers hope that their new plan may allow them to reactivate previously disabled systems on the twin space probes, but even if everything goes according to plan, there’s no fighting the inevitable. At some...
