“AI, Make Me A Degree Certificate”

November 10, 2025 by 92 Comments

One of the fun things about writing for Hackaday is that it takes you to the places where our community hang out. I was in a hackerspace in a university town the other evening, busily chasing my end of month deadline as no doubt were my colleagues at the time too. In there were a couple of others, a member who’s an electronic engineering student at one of the local universities, and one of their friends from the same course. They were working on the hardware side of a group project, a web-connected device which with a team of several other students, and they were creating from sensor to server to screen.

I have a lot of respect for my friend’s engineering abilities, I won’t name them but they’ve done a bunch of really accomplished projects, and some of them have even been featured here by my colleagues. They are already a very competent engineer indeed, and when in time they receive the bit of paper to prove it, they will go far. The other student was immediately apparent as being cut from the same cloth, as people say in hackerspaces, “one of us”.

They were making great progress with the hardware and low-level software while they were there, but I was saddened at their lament over their colleagues. In particular it seemed they had a real problem with vibe coding: they estimated that only a small percentage of their classmates could code by hand as they did, and the result was a lot of impenetrable code that looked good, but often simply didn’t work.

I came away wondering not how AI could be used to generate such poor quality work, but how on earth this could be viewed as acceptable in a university.

Switch Switch 2 To CRT

November 10, 2025 by 9 Comments

Have you ever imagined what the Nintendo Switch would look like if Nintendo had produced it in the mid-1990s? [Joel Creates] evidently did, because that’s exactly what this retro CRT-toting Switch 2 dock looks like.

Yes, it is portable, thanks to a 100W power bank torn apart and built into the 3D printed case. The full-color CRT comes from a portable TV, so it’s got portability in its heritage. Fitting all that chunky CRT goodness into a hand-held was, of course, a challenge. [Joel] credits AI slop with inspiring the 45-degree angle he eventually settled on. However, the idea of recessing handles inside the case so it could be thick enough but still comfortable to hold was all base-model H.Sap brainpower. There are shoulder controls hidden in those recesses, too, for the games that can use them.

We particularly like the cartridge-like way the Switch 2 slides into place with a satisfying click as its USB-C port connects. It’s plugging into an extension cable that leads to the guts of an official Nintendo dock, buried deeply (and conveniently) inside the 3D-printed box, stacked neatly with the HDMI-to-VGA and VGA-to-Composite converters [Joel] needed to get a nice 4:3 image on the CRT. No word on if he blows on the Switch 2 before plugging it in, but we certainly would.

We’ve featured plenty of portable game systems over the years, and some have been very well done, like this exquisitely done PS2 conversion — but very few have brought CRTs to the party. This retrofitted Game Boy is about the only exception, and [Joel] calls it out in his video as inspiration.

It looks like this is the first Switch 2 hack we’ve featured (with the exception of a teardown or two), so if you know of more, please let us know.

An Unnecessary (But Cool) Processor

November 10, 2025 by 17 Comments

[Bob] calls his custom 16-bit computer “Bob’s Unnecessary Retro Processor” or BURP for short. While we suppose it is technically unnecessary, we love the look of it, and we hope he just used it to get the quirky acronym.

When we build custom CPUs they look suspiciously like FPGA development boards, but not BURP. We immediately thought of the IMSAI and the H8 when we saw it, but [Bob] points out it also borrows from the PDP-11.

Recreating The Destroyed Case Of LGR’s Rare 1980s Laptop

November 9, 2025 by 4 Comments

A while back [Clint Basinger] of Lazy Game Reviews fame purchased a rare 1980s Halikan laptop. When he received the parcel, at first glance, everything seemed in order. Upon opening the original laptop bag, however, it was found that the combination of the heavy power supply in a side pocket and the brittle plastic of the laptop’s case had turned the latter into sad fragments of regret. At the time [Clint] wasn’t sure what he’d do, but fortunately [polymatt] stepped in with the joyful news: we can rebuild it; we have the technology.

Obviously, the sad plastic fragments of the original case weren’t going together again in any meaningful way, nor would this have been helpful, but the pieces, along with photos of an intact laptop, helped with the modelling of a digital model of the case. One model and one 3D printer is all you need. For this case, the print used ABS, with gaps between the segmented prints filled with an ABS slurry, as the case was too large to be printed without jumping through some hoops.

Have They Found A Complete UNIX V4?

November 9, 2025 by 19 Comments

If you’ve ever combed boxes of old tech detritus in search of a nugget of pure gold, we know you’ll appreciate the excitement of discovering, in a dusty University of Utah storeroom, a tape labelled “UNIX Original from Bell Labs V4 (See manual for format)”. If the tape contains what’s promised on the label, this is a missing piece of computer history, because no complete copies of this version are known to exist.

The tape will be delivered by hand to the Computer History Museum, where we hope its contents will be safely retrieved for archive and analysis. The reporter of the find, research professor [Rob Ricci], identifies the handwriting as that of Jay Lepreau, someone whose word on which UNIX version it contained could, we hope, be trusted.

Hackaday Links: November 9, 2025

November 9, 2025 by 23 Comments

We’re always a wee bit suspicious about articles that announce some sort of “World’s first” accomplishment. With a couple of hundred thousand years of history, most of which wasn’t recorded, over which something like 117 billion humans have lived, any claims of primacy have to be taken with a grain of salt. So when the story of the world’s first instance of a car being hit by a meteorite came across our feed, we had to check it out. The car in question, a Tesla, was being driven in South Australia by veterinarian Andrew Melville-Smith when something suddenly crashed into its windshield.

2025 Component Abuse Challenge: Dawg Gone LED Tester

November 9, 2025 by 23 Comments

The Hackaday 2025 Component Abuse Challenge is all about abusing electronic components in the service of making them do things they were never intended to. It’s not the 2025 Food Abuse Challenge, so in the case of [Ian Dunn]’s hot dog pressed into service as an LED tester, we’ll take the ‘dawg to be a component in its own right. And by any measure, it’s being abused!

Cooking hot dogs by passing an electric current through them has a long and faintly hazardous history to it — we’re sure we’ve heard of domestic hot dog cooker appliances that are little more than the mains supply on a pin at each end of a hot dog shaped receptacle. This one takes the ‘dawg in a bun with condiments, no less, and sticks an ordinary table fork wired up to the grid in each end. The LED testing is the cherry on the cake, because he simply sticks a pile of LEDs by their pins into the tasty sausage. It forms a crude potential divider, so there’s about enough volts across the gap between pins to light it up nicely.

We like this project on so many levels, though we’re not sure what heavy metals would leach out of those LED pins into the meat. If it’s inspired you to do something similar you still have a few days in which to enter the contest, so break out your convenience food and a pile of parts, and start experimenting!
