Play Games In UEFI…to Access Your Computer

January 9, 2026 by 9 Comments

These days, bootstrapping a computer is a pretty straight forward process, at least as far as the user is concerned. But in the olden days, one would have to manually flick switches entering binary code to get the computer to boot. While certainly not as painstaking as manually flipping bits, these games written for UEFI systems hearken back to the days when accessing your computer was a touch more complicated than pressing a power button.

The repository features five games ranging from a falling ball maze to an age verification quiz. The one thing they all have in common is that to complete system boot, you need to win. All are available in UEFI modules which can not only run in QEMU virtual machines, but bare metal if you so choose.

In no particular order, the games featured are a User Evaluation For Ineptness, which presents a simple addition problem for the user to complete. Insult Sword Fighting, which requires the user to select the correct come back to a prompted insult. Fall To Boot, a falling ball maze navigation game. Age Verification, a set of questions about 80s culture to prove the user is old enough to use the computer. And finally, UEFI Says, a simple memory game.

All of these games are fairly simple, but it’s rather fun to see them built using EDK II as a UEFI module. Let us know down in the comments which is your favorite. And if you’re running an ARM computer, you too can join in on the fun!

Thanks [thatsgrand] for the tip!

 

 

Scientific staff members working on the computing machine Setun

The Setun Was A Ternary Computer From The USSR In 1958

January 3, 2026 by 45 Comments

[Codeolences] tells us about the FORBIDDEN Soviet Computer That Defied Binary Logic. The Setun, the world’s first ternary computer, was developed at Moscow State University in 1958. Its troubled and short-lived history is covered in the video. The machine itself uses “trits” (ternary digits) instead of “bits” (binary digits).

When your digits have three discrete values there are a multiplicity of ways of assigning meaning to each state, and the Setun uses a system known as balanced ternary where each digit can be either -1, 0, or 1 and otherwise uses a place-value system in the normal way.

An interesting factoid that comes up in the video is that base-3 (also known as radix-3) is the maximally efficient way to represent numbers because three is the closest integer to the natural growth constant, the base of the natural logarithm, e, which is approximately 2.718 ≈ 3.

Benchmarking Windows Against Itself, From Windows XP To Windows 11

January 2, 2026 by 92 Comments

Despite faster CPUs, RAM and storage, today’s Windows experience doesn’t feel noticeably different from back in the 2000s when XP and later Windows 7 ruled the roost. To quantify this feeling, [TrigrZolt] decided to run a series of benchmarks on a range of Windows versions.

Covering Windows XP, Vista, 7, 8.1, 10 and 11, the Pro version of each with the latest service packs and updates was installed on the same laptop: a Lenovo ThinkPad X220. It features an Intel i5 2520M CPU, 8 GB of RAM, built-in Intel HD Graphics 3000 and a 256 GB HDD.

For start-up, Windows 8.1 won the race, probably due to having the Fast Boot feature, while Windows 11 came in dead last as it showed the desktop, but struggled to show the task bar. Windows XP’s install size was the smallest and also had the lowest RAM usage with nothing loaded at 800 MB versus 3.3 GB for Windows 11 in last place.

3D Printed PC Case Focuses On Ease Of Access

December 26, 2025 by 24 Comments

There are all kinds of fun, glowing PC cases on the market these days. However, if you want something that focuses on serviceability over flash while still looking stylish, you might like the Makeyo MK01. It’s a PC case that you can print yourself, and [Marst_art] has published a video on what it’s like to whip one up at home.

The MK01 is assembled from lots of smaller parts, so the components can be made on any 3D printer that has a print area of 210 x 210 mm or more. All the outer panels are affixed to the main chassis with magnets, which makes servicing easy. You can just pop off panels when you need to get inside without undoing any fasteners or clips.

Plus, the cool thing about the MK01 is that since you’re printing it yourself, you can easily make whatever mods you like prior to printing it out. [Marst_art] notes that he threw in a USB-C port to the front panel for easy access, and a few internal mounts for 2.5″ SSDs. He also made some mods to the power switch assembly. It also bears noting—you get to choose your own color scheme when you make one of these. This level of customization is something you simply don’t get when you buy off the shelf!

[Marst_art]’s video is a useful guide if you’re planning to undertake such a build yourself. It outlines what it’s like to actually print one of these things on a consumer printer, and how the settings will influence the final look and feel. It’s worth noting that you’ll probably want to print this in ABS or another filament that can handle high heat, unless you’re building a very cool running machine.

It’s not just a great looking case, it’s a highly functional one, too. Files are available on Printables if you’d like to make your own. We’ve featured other printed cases before, too.

PC Watercooling Uses Everything But CNC Machining

December 26, 2025 by 1 Comment

Names and labels are difficult. Take this “3D Printed” water-cooling loop by [Visual Thinker] on YouTube. It undeniably uses 3D printing — but it also uses silicone casting and laser-cut acrylic, too. All of these are essential parts, yet only 3D printing gets top billing in his thumbnail. At least the version we saw, anyway; the A/B testing game YouTubers play means that may change.

Perhaps that’s simply due to the contrast with [Visual Thinker]’s last build, where the “distro plate” that acts to plumb most of the coolant was made of layers of CNC-routed acrylic, held water-tight with O-rings. Not wanting to wait for his next build to be fabricated, and not wanting to take up CNC machining himself, [Visual Thinker] fell back on tools many of us have and know: the 3D printer and laser cutter.

In this project, the end plates of the cooling loop are still clear acrylic, but he’s using a laser cutter to shape them. That means he cannot route out gaps for o-rings like in the last project, so that part gets 3D printed. Sort of. Not trusting the seal a 3D printed gasket would be able to give him, [Visual Thinker] opts to use his 3D printer to create a mold to cast a seal in silicone. Or perhaps “injection-mold” would be a better word than cast; he’s using a large syringe to force the degassed silicone into the mold. The end part is three pieces: a 3D printed spacer holding two acrylic plates, with the cast-silicone gasket keeping the whole thing water-tight to at least 50 psi, 10x the operating pressure of his PC.

After that success, he tries replacing the printed spacer with acrylic for a more transparent look. In that version only temporary shims that are used to form the mold are 3D printed at all, and the rest is acrylic. Even if you’re not building a water-cooled art PC, it’s still a great technique to keep in your back pocket for fluid channeling.

In some ways, this technique is the exact opposite of the copper-pipe steampunk builds we’ve featured previously. Those were all about pretty plumbing, while with a distro plate you hardly need pipes at all. Like any water-cooled project, it’ll need a radiator, which could be a hack in and of itself.

Automatically Remove AI Features From Windows 11

December 18, 2025 by 66 Comments

It seems like a fair assessment to state that the many ‘AI’ features that Microsoft added to Windows 11 are at least somewhat controversial. Unsurprisingly, this has led many to wonder about disabling or outright removing these features, with [zoicware]’s ‘Remove Windows AI’ project on GitHub trying to automate this process as much as reasonably possible.

All you need to use it is your Windows 11-afflicted system running at least 25H2 and the PowerShell script. The script is naturally run with Administrator privileges as it has to do some manipulating of the Windows Registry and prevent Windows Update from undoing many of the changes. There is also a GUI for those who prefer to just flick a few switches in a UI instead of running console commands.

Among the things that can be disabled automatically are the disabling of Copilot, Recall, AI Actions, and other integrations in applications like Edge, Paint, etc. The reinstallation of removed packages is inhibited by a custom package. For the ‘features’ that cannot be disabled automatically, there is a list of where to toggle those to ‘off’.

Naturally, since Windows 11 is a moving target, it can be rough to keep a script like this up to date, but it seems to be a good start at least for anyone who finds themselves stuck on Windows 11 with no love for Microsoft’s ‘AI’ adventures. For the other features, there are also Winaero Tweaker and Open-Shell, with the latter in particular bringing back the much more usable Windows 2000-style start menu, free of ads and other nonsense.

Jenny’s Daily Drivers: Haiku R1/beta5

December 11, 2025 by 17 Comments

Back in the mid 1990s, the release of Microsoft’s Windows 95 operating system cemented the Redmond software company’s dominance over most of the desktop operating system space. Apple were still in their period in the doldrums waiting for Steve Jobs to return with his NeXT, while other would-be challengers such as IBM’s OS/2 or Commodore’s Amiga were sinking into obscurity.

Into this unpromising marketplace came Be inc, with their BeBox computer and its very nice BeOS operating system. To try it out as we did at a trade show some time in the late ’90s was to step into a very polished multitasking multimedia OS, but sadly one which failed to gather sufficient traction to survive. The story ended in the early 2000s as Be were swallowed by Palm, and a dedicated band of BeOS enthusiasts set about implementing a free successor OS. This has become Haiku, and while it’s not BeOS it retains API compatibility with and certainly feels a lot like its inspiration. It’s been on my list for a Daily Drivers article for a while now, so it’s time to download the ISO and give it a go. I’m using the AMD64 version.
