Running DOOM on ARM? Old hat. Running Doom (2016) on an ARM SBC? Well, that’s a bit more interesting, and [Interfacing Linux] shows us how with this handy guide, and in a video embedded below…

What if you build a clock that displayed the time not just on its own, but in its shadows as well? [Lewis] from [DIY Machines] has done just that, with a nifty 3D-printed shadow clock build. The cl…

If you are anything like us, last time you went bowling, you thought more about how the ball came back to you than actually knocking down the pin. Perhaps you even wondered what it would be like to…

If the idea of reading a physical book sounds like hard work, [Nick Bild’s] latest project, the PageParrot, might be for you. While AI gets a lot of flak these days, one thing modern multimod…

There is always the promise of using more computing power for a single task. Your computer has multiple CPUs now, surely. Your video card has even more. Your computer is probably networked to a sle…

While for most people Pluto is the most distant planet in the Solar System, things get a lot more fuzzy once you pass Neptune and enter the realm of trans-Neptunian objects (TNOs). Pluto is probabl…

These are tough times for American hackers, and rife with uncertainty. Trade wars are on, off, on again– who can keep track? If you’re used to getting everything from China, that can re…

AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have m…

Although not nearly as intimidating as her ceiling-mounted hanging arm body, GLaDOS spent a significant portion of the Portal 2 game in a stripped-down computer powered by a potato battery. [Dave] …

X-ray crystallography, like mass spectroscopy and nuclear spectroscopy, is an extremely useful material characterization technique that is unfortunately hard for amateurs to perform. The physical o…

Aside from GPUs, you don’t hear much about co-processors these days. [bitluni] perhaps missed those days, because he found a way to squeeze a 160 core RISC V supercluster onto a single m.2 bo…

Anthropic has had an eventful couple weeks, and we have two separate write-ups to cover. The first is a vulnerability in the Antropic MCP Inspector, CVE-2025-49596. We’ve talked a bit about t…

Cable harness design is a critical yet often overlooked aspect of electronics design, just as essential as PCB design. While numerous software options exist for PCB design, cable harness design too…

If you have any empathy at all for those of us in the journalistic profession, have some pity for the poor editor at the Chicago Sun-Times, who let through an AI-generated summer reading list made …

Photography is great, but sometimes it can get boring just reusing the same wavelengths over and over again. There are other options, though and when [Malcolm Wilson] decided he wanted to explore t…

Ever have one of those ideas that’s just so silly, you just need to run with it? [Chris] from Sound Workshop ran into that when he had the idea that became the Pneumatone: a woodwind instrume…

Commercial 3D printers keep getting faster and faster, but we can confidently say that none of them is nearly as fast as [Jan]’s Minuteman printer, so named for its goal of eventually printing a 3D…

In the comments of a recent article, the question came up as to where to find projects from the really smart kids the greybeards remember being in the 70s. In the case of [Will Dana] the answer is …
