Recreating the Destroyed Case of LGR’s Rare 1980s Laptop

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.

The original enclosure’s plastic was analyzed by [Blaise Mibeck] at Cubic Labs to determine why it failed. Under an electron microscope at 15,000x magnification, it was clear that microfractures had formed, likely induced by visible voids due to mechanisms such as off-gassing from volatile compounds inside the plastic. Around these voids, bromine (Br) was present — a common fire retardant — suggesting that Br-based fire retardant compounds played a major role in weakening the plastic.

The final case model is very faithful, although some things, like embossed letters, do not print well with an FDM printer like the Bambu Lab H2D used here. Before assembly, the old NiCd RTC battery was replaced, as was the NiCd battery pack. The main pack got a NiMH upgrade. There was also a blown 5V rail fuse, which likely wasn’t part of the transport damage, but had to be fixed regardless.

After giving the keyboard with its mechanical keys a good clean, assembly of the laptop could commence. This left [polymatt] with the working laptop, including a working hard drive, ready to be sent back to [Clint] for final testing. We’re looking forward to seeing the LGR video on this laptop, and in case [Clint] or anyone else needs to print a Chaplet Halikan LA-30A case ever again, [polymatt] was kind enough to put the files up on Printables.

Hackaday Links: November 9, 2025

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.

The Tesla, which was in Autopilot mode at the time, continued on its merry way, which likely means its cameras didn’t see anything out of the ordinary. While this potentially supports the claim that the impactor came from above, the fact that the windshield wasn’t fully penetrated kind of speaks against that hypothesis. Also arguing against a cosmogenic origin for the impactor is the inability to find anything on the roadway near the crash site. But Dr. Melville-Smith is adamant that it must have been a meteorite due to evidence of the windshield glass having melted slightly. Again, this raises a few red flags for us, as anything energetic enough to melt glass on impact surely would have gone straight through the windshield, the driver, the seat, the floor, the battery pack, and probably the roadway, too. Then again, we recently saw a legit meteorite impact caught on camera, and that was a surprisingly low-energy event. Oh, and the “first ever” claim? Maybe not, since it seems as if a moving car was struck by a meteorite back in 1950.

Well, that’s it, folks, we’re calling it: the New Space Race is over, and the Chinese have won. Have they landed on the Moon? Set foot on Mars? No, nothing boring like that — they served up the first barbecue in space! The seminal accomplishment came after the installation of a new oven on the Tiangong space station, which is apparently a souped-up microwave with some air-fryer-like features. The six taikonauts currently aboard the space station put the new appliance through its paces with chicken wings, which were sent up on a recent supply run. The linked article has a picture of the wings, which honestly look a little wimpy compared to Buffalo wings; then again, some of the — ahem — aftereffects of properly spiced hot wings might not go over so well in a closed environment. Regardless, we’re sure the meal was a welcome change from the usual space food fare, especially compared to the offerings aboard the ISS, which seem pretty meager. All we’ve ever seen there are tortillas smeared with peanut butter. Pretty sad.

If you’re of a certain vintage and want to feel old, check this out: it’s been 37 years since the “Morris Worm” made cybersecurity a thing. The Internet worm, which exploited a couple of vulnerabilities in Unix systems to propagate, was written by Robert Morris at Cornell University, who has always claimed that he did it just to see if it could be done. It could and it did, infecting 10% of the machines on the fledgling Internet within 24 hours and causing damage (in the form of post-infection mitigation effort) to the tune of $10,000,000. In an interesting twist, Morris was the son of cryptologist Robert Morris, who played a role in the events described in The Cuckoo’s Egg by Cliff Stoll.

And finally, there are more than a few ways to start a flame war in the comments section — Metric vs. Imperial, emacs vs. vi, ridiculously clunky and horrible UK power plugs vs. plugs from literally anywhere else in the world — but one sure way to set one off is to pit Wago lever-lock terminals against good old American wire nuts. Personally, we can see the case for each and make use of both types of connectors in our projects, but if you can’t bear to suffer the slings and arrows of using “those European things” in a proper American junction box, these Wago-disguising 3D prints might be right up your alley. Designed to slip over the two-circuit version of the lever-lock connector, these will hide your shame at not being willing or able to twist a couple of wires together with wire nuts. Have fun in the comments!

Have They Found a Complete UNIX V4?

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.

So if you happen to have a handy PDP-11 in your basement, you may soon be able to explore this 1973 version of the OS. We look forward to hearing from the Computer History Museum as they analyse the tape. Meanwhile, if this whole UNIX thing is new to you, we have a Bell Labs introduction to help you. Or check out the illustrious panel below, looking back at 50 years of UNIX.

Concrete Lathe Turns Metal

Full disclosure. If you want a lathe capable of turning metal stock, you probably should just buy one. But what fun is that? You can do like [kachurovskiy] and build one with your 3D printer. If you are chuckling, thinking you can’t make 3D printed parts sturdy enough, you aren’t exactly wrong. [Kachurovskiy’s] trick is to 3D print forms and then cast the solid parts in concrete. The result looks great, and we don’t doubt his claim that it “can surpass many comparable lathes in rigidity and features.”

Even he admits that this is a “… hard, long, and expensive project…” But all good projects are. There’s a GitHub page with more details and informative videos below. The action shots are in the last video just before the six-minute mark. Around the seven-minute mark, you can see the machine cut a conical thread. Color us impressed!

The idea of casting concrete with inserts in it is giving us a number of ideas. We haven’t done it before, but it looks like a good skill to learn. You can 3D print concrete, too. Concrete lathes are, surprisingly, not a new idea, but much harder to do without 3D-printed forms.

2025 Component Abuse Challenge: Dawg Gone LED Tester

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!
