Break out your tuxedo or your evening gown, we’re going to take in some highbrow culture. A night at the opera perhaps, some Tchaikovsky from the symphony orchestra, or maybe a bit of Shakespeare? No, we’re going to a demo party, because the demoscene is the latest art form to be accepted as officially a part of the national cultural heritage of the Netherlands. This builds on successes adding the scene to the cultural heritage registers of Finland, Germany, and Poland, and should provide a boost to other bids in countries such as Switzerland and eventual UNESCO world acceptance.
It’s all very cool that one of our wider community’s art forms is at last being taken seriously rather than being dismissed by the establishment, because along with greater recognition comes other benefits. Sadly we don’t expect any cities to shell out for a demo auditorium next to the shiny new opera house any time soon, but we can see that it could be used to the benefit of for example a hackerspace chasing grants. meanwhile, feast your eyes on a bit of cultural heritage courtesy of the Dutch Centre For Intangible Cultural Heritage (Dutch language, English translation).
An IBM (or, later, Lenovo) ThinkPad is a popular choice in our community. They’re prized for their rugged design, longevity, and good software support. Over the many years that the line has been available, there have been a few models which have captured the attention more than others, and among those, probably the most sought-after is the ThinkPad 701c. It would be an unremarkable mid-1990s 486 laptop were it not for the party piece of that flip-out butterfly keyboard (see video, below). [Karl Buchka] has one that’s profoundly dead, and rather than use it as a novelty paperweight, he’s giving it a new lease of life with a Framework motherboard.
This is very much a work in progress, so there will be plenty more to come, but so far, he’s taken the display panel from an iPad and made it work with the Framework board, and designed an entirely new lower case for the Thinkpad. This will hold the Framework board with its USB-C ports at the edge, so in the place of its USB-based expansion modules, he’s made a custom external port replicator. Meanwhile, a Teensy handles that unique keyboard. We’re told that the design files will all eventually be put online should anyone else want to try.
We’d normally be slightly upset were someone to butcher something as unusual as a 701c, however, in thic ase we can see that it turns a broken computer into one that should see quite a bit of use. We can’t help envying him this project.
Understandably not many 701c owners have dived inside their machines, but we have previously brought you a contemporary processor upgrade. If you’ve never seen the 701c’s keyboard — or you just want to see it again — here you go:
One of the best things about Linux is that there are always multiple ways to do anything you want to do. However, some ways are easier than others. Take, for example, virtual networking. There are plenty of ways to make a bunch of Internet-connected computers appear to be on a single private network. That’s nothing new, of course. Linux and Unix have robust networking stacks. Since 2018, though, Wireguard has been the go-to solution; it has a modern architecture, secure cryptography, and good performance.
There’s only one problem: it is relatively difficult to set up. Not impossible, of course. But it is a bit difficult, depending on what you want to accomplish.
How Difficult?
You must set up a wireguard server and one or more clients. You’ll need to pick a range of IP addresses. You might need to turn on routing. You have to generate keys. You might need to configure DNS and other routing options. You’ll certainly need to modify firewall rules. You’ll also need to distribute keys.
None of these steps are terribly difficult, but it is a lot to keep straight. The wg program and wg-quick script do most of the work, but you have a lot of decisions and configuration management to keep straight.
Browse the official “quick start,” and you’ll see that it isn’t all that quick. The wg-quick script is better but only handles some use cases. If you want really limited use cases, there are third-party tools to do a lot of the rote work, but if you need to change anything, you’ll still need to figure it all out.
Bureaucracies generate paper, usually lots of paper. Anything you consider private — especially anything that could get you in trouble — should go in a “burn box” which is usually a locked trash can that is periodically emptied into an incinerator. However, what about a paper shredder? Who hasn’t seen a movie or TV show where the office furiously shreds papers as the FBI, SEC, or some other three-letter-agency is trying to crash the door down?
That might have been the scene in the late 1980s when Germany reunified. The East German Ministry of State Security — known as the Stasi — had records of unlawful activity and, probably, information about people of interest. The staff made a best effort to destroy these records, but they did not quite complete their task.
The collapsing East German government ordered documents destroyed, and many were pulped or burned. However, many of the documents were shredded by hand, stuffed into bags, and were awaiting final destruction. There were also some documents destroyed by the interim government in 1990. Today there are about 16,000 of these bags remaining, each with 2,500 to 3,000 pieces of pages in them.
Machine-shredded documents were too small to recover, but the hand-shredded documents should be possible to reconstruct. After all, they do it all the time in spy movies, right? With modern computers and vision systems, it should be a snap.
A few years ago, there was a rush of products on the market to detect motion. The idea being you could interact with your computer like they do on science fiction movies, with giant expressive hand motions in the air. Most of these were aimed at desktop computer users but one company, YouSpace, wanted to bring this technology to retail stores. [IMSAI Guy] got one of their sensor devices and decided to see what was inside it. You can see, too, in the video below.
The device appeared to have a laser inside, which motivated the teardown. We aren’t sure exactly what YouSpace had planned, but you can see their now-defunct website on the Wayback machine. The use cases listed didn’t really help us get a clear picture, so maybe that was part of the problem.
Getting into the device was the first challenge. Like many modern smartphones, there didn’t appear to be any fasteners, so you simply had to pry the case apart. Inside the case: a tiny circuit board and a metal assembly containing the laser and cameras that were easy to remove. The main PCB appears to be an Intel off-the-shelf board that was in many Intel RealSense products, and currently go for about $50 on eBay. The camera assembly looks a bit like an Intel D430, so it is possible the entire thing was off-the-shelf hardware. Even the little connector board is, technically, a D400 Interposer.
The peek into the structured light project under the microscope was interesting. We expected it would look different, and [IMSAI Guy] clearly didn’t expect its appearance either. The chip was made to beam a known pattern that the cameras would use to deduce the shape of the surfaces it hits.
If you can find these on the surplus market, they would probably be a good deal if you need this hardware which is typically pretty expensive. Just beware, though. Intel announced in late 2021 they were “winding down” RealSense. We don’t know if there will be third-party support in the future or if the whole product line will just be orphaned.
Over the years, I’ve been curious to dig deeper into the world of the manufacturing in China. But what I’ve found is that Western anecdotes often felt surface-level, distanced, literally and figuratively from the people living there. Like many hackers in the west, the allure of low-volume custom PCBs and mechanical prototypes has me enchanted. But the appeal of these places for their low costs and quick turnarounds makes me wonder: how is this possible? So I’m left wondering: who are the people and the forces at play that, combined, make the gears turn?
Enter Prototype Nation: China and the Contested Promise of Innovation, by Silvia Lindtner. Published in 2020, this book is the hallmark of ten years of research, five of which the author spent in Shenzhen recording field notes, conducting interviews, and participating in the startup and prototyping scene that the city offers.
This book digs deep into the forces at play, unraveling threads between politics, culture, and ripe circumstances to position China as a rising figure in global manufacturing. This book is a must-read for the manufacturing history we just lived through in the last decade and the intermingling relationship of the maker movement between the west and east.
The future, as seen in the popular culture of half a century or more ago, was usually depicted as quite rosy. Technology would have rendered every possible convenience at our fingertips, and we’d all live in futuristic automated homes — no doubt while wearing silver clothing and dreaming about our next vacation on Mars.
Of course, it’s not quite worked out this way. A family from 1965 whisked here in a time machine would miss a few things such as a printed newspaper, the landline telephone, or receiving a handwritten letter; they would probably marvel at the possibilities of the Internet, but they’d recognise most of the familiar things around us. We still sit on a sofa in front of a television for relaxation even if the TV is now a large LCD that plays a streaming service, we still drive cars to the supermarket, and we still cook our food much the way they did.

The Future is Here, and it Responds to “Alexa”

There’s one aspect of the Jetsons future that has begun to happen though. It’s not the futuristic automation of projects such as Disneyland’s Monsanto house Of The Future, but instead it’s our current stuttering home automation efforts. We’re not having domestic robots in pinnies hand us rolled-up newspapers, but we’re installing smart lightbulbs and thermostats, and we’re voice-controlling them through a variety of home hub devices. The future is here, and it responds to “Alexa”.
But for all the success that Alexa and other devices like it have had in conquering the living rooms of gadget fans, they’ve done a poor job of generating a profit. It was supposed to be a gateway into Amazon services alongside their Fire devices, a convenient household companion that would help find all those little things for sale on Amazon’s website, and of course, enable you to buy them. Then, Alexa was supposed to move beyond your Echo and into other devices, as your appliances could come pre-equipped with Alexa-on-a-chip. Your microwave oven would no longer have a dial on the front, instead you would talk to it, it would recognise the food you’d brought from Amazon, and order more for you.
Instead of all that, Alexa has become an interface for connected home hardware, a way to turn on the light, view your Ring doorbell on models with screens, catch the weather forecast, and listen to music. It’s a novelty timepiece with that pod bay doors joke built-in, and worse that that for the retailer it remains by its very nature unseen. Amazon have got their shopping cart into your living room, but you’re not using it and it hardly reminds you that it’s part of the Amazon empire at all.
But it wasn’t supposed to be that way. The idea was that you might look up from your work and say “Alexa, order me a six-pack of beer!”, and while it might not come immediately, your six-pack would duly arrive. It was supposed to be a friendly gateway to commerce on the website that has everything, and now they can’t even persuade enough people to give it a celebrity voice for a few bucks.
The Gadget You Love to Hate
In the first few days after the Echo’s UK launch, a member of my hackerspace installed his one in the space. He soon became exasperated as members learned that “Alexa, add butt plug to my wish list” would do just that. But it was in that joke we could see the problem with the whole idea of Alexa as an interface for commerce. He had locked down all purchasing options, but as it turns out, many people in San Diego hadn’t done the same thing. As the stories rolled in of kids spending hundreds of their parents’ hard-earned on toys, it would be a foolhardy owner who would leave left purchasing enabled. Worse still, while the public remained largely in ignorance the potential of the device for data gathering and unauthorized access hadn’t evaded researchers. It’s fair to say that our community has loved the idea of a device like the Echo, but many of us wouldn’t let one into our own homes under any circumstances.
So Alexa hasn’t been a success, but conversely it’s been a huge sales success in itself. The devices have sold like hot cakes, but since they’ve been sold at close to cost, they haven’t been the commercial bonanza they might have hoped for. But what can be learned from this, other than that the world isn’t ready for a voice activated shopping trolley?
Sadly for most Alexa users it seems that a device piping your actions back to a large company’s data centres is not enough of a concern for them. It’s an easy prediction that Alexa and other services like it will continue to evolve, with inevitable AI pixie dust sprinked on them. A bet could be on the killer app being not a personal assistant but a virtual friend with some connections across a group of people, perhaps a family or a group of friends. In due course we’ll also see locally hosted and open source equivalents appearing on yet-to-be-released hardware that will condense what takes a data centre of today’s GPUs into a single board computer. It’s not often that our community rejoices in being late to a technological party, but I for one want an Alexa equivalent that I control rather than one that invades my privacy for a third party.
