Old IPad Keyboard Makes For A Modern Netbook

Netbooks were a class of tiny laptops which hit their peak over a decade ago, with the idea being that you could use the Internet and do your computing on the move with ease. Unfortunately manufacturers were scared of them eating their profits from bigger computers, and they were invariably built to a very disappointing spec. That doesn’t lessen the appeal of small form factor laptops though, and [bob-foss] is here with a simple hack to make one.

He’s taken a hinged keyboard case made for one of the previous generations of iPad Mini, and paired it with a high-end Lenovo gaming tablet by way of a 3D printed replacement for the original Apple-grabber. We said it was a simple hack and it is, but it’s no less elegant for that as the detail is what matters. This isn’t a mess-of-wires cyberdeck, instead it’s a machine you could pull out on a train and get some work done.

Meanwhile, if you’d like to take a wallow in what that netbook thing was all about, we took a look at the phenomenon back in 2020.

Ruined 1993 ThinkPad Tablet Brought Back From The Brink

Collecting retrocomputers is fun, especially when you find fully-functional examples that you can plug in, switch on, and start playing with. Meanwhile, others prefer to find the damaged examples and nurse them back to health. [polymatt] can count himself in that category, as evidenced by his heroic rescue of an 1993 IBM ThinkPad Tablet.

The tablet came to [polymatt] in truly awful condition. Having been dropped at least once, the LCD screen was cracked, the case battered, and all the plastics were very much the worse for wear. Many of us would consider it too far gone, especially considering that replacement parts for such an item are virtually unobtainable. And yet, [polymatt] took on the challenge nonetheless.

Despite its condition, there were some signs of life in the machine. The pen-based touch display seemed to respond to the pen itself, and the backlight sort of worked, too. Still, with the LCD so badly damaged, it had to be replaced. Boggling the mind, [polymatt] was actually able to find a 9.4″ dual-scan monochrome LCD that was close enough to sort-of fit, size-wise. To make it work, though, it needed a completely custom mount to fit with the original case and electromagnetic digitizes sheet. From there, there was plenty more to do—recapping, recabling, fixing the batteries, and repairing the enclosure including a fresh set of nice decals.

The fact is, 1993 IBM ThinkPad Tablets just don’t come along every day. These rare specimens are absolutely worth this sort of heroic restoration effort if you do happen to score one on the retro market. Video after the break.

Keebin’ With Kristina: The One With The Pickle Pi

The unstoppable [jefmer] wrote in to alert me to Pickle Pi, their latest Keebin’-friendly creation. Why “Pickle Pi”? Well, the Pi part should be obvious, but the rest comes from the Gherkin 30% ortholinear keyboard [jefmer] built with Gateron Yellows and, unfortunately, second-choice XDA keycaps, as the first batch were stolen off of the porch.

If you’re wondering where the rest of the keys are, they are accessible by holding various keys rather than tapping them. Shift is Shift when tapped held, but becomes Enter when tapped. [jefmer] wrote out their entire project description on the thing in order to break in the Gherkin.

The brains of this acrylic sandwich tablet is a Pi Zero 2, with a Pro Micro for the keyboard controller. Although programs like Ghostwriter and Thonny work fine, Chromium is “painfully slow” due to the RAM limitations of the Pi Zero 2. On the upside, battery life is 7-8 hours depending on usage. Even so, [jefmer] might replace it with a Pi 4 — the current battery pack won’t support a Pi 5.

Streaming Deck Removes Need For Dedicated Hardware

Streaming content online has never been more popular than it is now, from YouTube to Twitch there are all kinds of creators around with interesting streams across a wide spectrum of interests. With that gold rush comes plenty of people selling figurative shovels as well, with audio mixing gear, high-quality web cams, and dedicated devices for controlling all of this technology. Often these devices take the form of a tablet-like device, but [Lenochxd] thinks that any tablet ought to be able to perform this task without needing dedicated, often proprietary, hardware.

The solution offered here is called WebDeck, an application written in Flask that turns essentially any device with a broswer into a stream control device. Of course it helps to have a touch screen as well, but an abundance of tablets and smartphones in the world makes this a non-issue. With the software running on the host computer, the streamer can control various aspects of that computer remotely by scanning a QR code which opens a browser window with all of the controls accessible from within. It has support for VLC, OBS Studio, and Spotify as well which covers the bases for plenty of streaming needs.

Currently the host software only runs on Windows, but [Lenochxd] hopes to have MacOS and Linux versions available soon. We’re always in favor of any device that uses existing technology and also avoids proprietary hardware and software. Hopefully that’s a recipe to avoid planned obsolescence and unnecessary production. If you prefer a version with a little bit of tactile feedback, though, we’ve seen other decks which add physical buttons for quick control of the stream.

Build A Tablet Out Of Your Framework Motherboard

The Framework laptop project is known for quite a few hacker-friendly aspects. For example, they encourage you to reuse its motherboard as a single-board computer – making it into a viable option for your own x86-powered projects. They have published a set of CAD files for that, and people have been working on their own Framework motherboard-based creations ever since; our hacker, [whatthefilament], has already built a few projects around these motherboards. Today, he’s showing us the high-effort design that is the FrameTablet – a 15″ device packing an i5 processor, all in a fully 3D printed chassis. The cool part is – thanks to his instructions, you can build one yourself!

This tablet sports a FullHD touchscreen IPS display and shows some well-thought-out component mounting, using heat-set inserts and screws, increasing such a build’s mechanical longevity. You lose one of the expansion card slots to the USB-C-connected display, but it’s a worthwhile tradeoff, and the touchscreen functionality works wonders in Windows. [whatthefilament] has also published a desk holder and a wall mount to accompany this design – if it’s a bit too large for you to hold in some situations, you can mount it in a more friendly, hands-free way. This is a solid and surprisingly practical tablet, and unlike the Raspberry Pi tablet builds we’ve seen, its x86 heart packs enough power to let you do things like CAD on the go.

With STLs and STEPs available, his build is a decent option for when you’ll want to replace your Framework’s motherboard with a new, upgraded one. You might’ve already noticed a few high-effort projects with these motherboards on our pages – perhaps, this transparent shell handheld with a mech keyboard and trackball, or this personal terminal with a futuristic-looking round display. This project is part of the “send 100 motherboards to hackers” initiative that Framework organized a few months ago, and we can’t say it hasn’t been working out for them!

PERSEUS-9, The Dual-6502 Portable Machine That Should Have Been

A question: does anyone who was around in the early days of the 8-bit computer revolution remember a dual-CPU 6502 portable machine like this one? Or just a dual-CPU machine? Or even just a reasonably portable computer? We don’t, but that begs a further question: if [Mitsuru Yamada] can build such a machine today with parts that were available in the era, why weren’t these a thing back then?

We’re not sure we have an answer to that question, but it just may be that nobody thought of it. Or, if they did, the idea of putting two expensive CPUs into a single machine was perhaps too exorbitant to take seriously. Regardless, the homemade mobile is another in a growing line of beautifully crafted machines in the PERSEUS line, all of which have a wonderfully similar look and feel.

For the PERSEUS-9, [Yamada-san] chose a weatherproof aluminum enclosure with just the right form-factor for a mobile computer, as well as a sturdy industrial look. Under the hood, there are two gorgeous wire-wrap boards, one of which is home to the 48-key keyboard and the 40×7 alphanumeric LED matrix display, while the other is a densely packed work of art holding the two 6502s and a host of other DIPs.

The machine is a combination of his PERSEUS-8 computer, his 6802 serial terminal, and the CI-2 floating point interpreter he built for the PERSEUS-8. A brief video of the assembly of this delightful machine is below. One of the many things about these builds that impress us is the precision with which the case is machined, apparently all by hand. How he managed to drill out all those holes for the keyboard without having one even slightly out of alignment without the aid of CNC is beyond us.

Hackaday Links: November 21, 2021

As the most spendiest time of the year rapidly approaches, it’s good to know that your hard-earned money doesn’t have to go towards gifts that are probably still sitting in the dank holds of container ships sitting at anchor off the coast of California. At least not if you shop the Tindie Cyber Sale that started yesterday and goes through December 5. There’s a lot of cool stuff on sale, so it shouldn’t be too hard to find something; to sweeten the deal, Jasmine tells us that there will be extra deals going live on Black Friday and Cyber Monday. But wait, there’s more — follow Tindie on Twitter for bonus discount codes.

Blue is the old black, which was the new blue? At least when it comes to “Screens of Death” it is, since Microsoft announced the Windows 11 BSOD will revert back from its recent black makeover to the more familiar blue theme. You’ll have to scroll down a bit, perhaps three-quarters of the way through the list of changes. Again, the change seems completely cosmetic and minor, but we’d still love to know what kind of research went into making a decision like this.

From the “One Man’s Trash” department, we have a request for help from reader Mike Drew who picked up a bunch — like, a thousand — old tablet computers. They originally ran Windows but they can run Linux Mint just fine, and while they lack batteries and the back cover, they’re otherwise complete and in usable condition, at least judging by the pictures he shared. These were destined for the landfill, but Mike is willing to send batches of 10 — no single units, please — to anyone who can cover the cost of packaging and shipping. Mike says he’ll be wiping the tablets and installing Mint, and will throw in a couple of battery cables and a simple instruction sheet to get you started. If you’re interested, Mike can be reached at michael.l.drew@gmail.com. Domestic shipping only, please. Here’s hoping you can help a fellow hacker reclaim a room in his house.

Answering the important questions: it turns out that Thanos couldn’t have snapped half of the universe out of existence after all. That conclusion comes from a scientific paper, appearing in the Journal of the Royal Society. While not setting out to answer if a nigh-invulnerable, giant purple supervillain could snap his fingers, it’s pretty intuitive that wearing any kind of gloves, let alone a jewel-encrusted metal gauntlet, makes it hard to snap one’s fingers. But the mechanics of snapping is actually pretty cool, and has implications beyond biomechanics. According to the paper, snapping is actually an example of latch-mediated spring actuation, with examples throughout the plant and animal kingdoms, including the vicious “one-inch punch” of the tiny mantis shrimp. It turns out that a properly executed human finger snap is pretty darn snappy — it takes about seven milliseconds to complete, compared to 150 milliseconds for an eye blink.

And finally, it seems like someone over at Id Software is a bit confused. The story began when a metal guitarist named Dustin Mitchell stumbled across the term “doomscroll” and decided that it would make a great name for a progressive thrash metal band. After diligently filing a trademark application with the US Patent and Trademark Office, he got an email from an attorney for Id saying they were going to challenge the trademark, apparently because they feel like it will cause confusion with their flagship DOOM franchise. It’s hard to see how anyone who lived through the doomscrolling years of 2020 and 2021 is going to be confused by a thrash metal band and a 30-year-old video game, but we suppose that’s not the point when you’re an attorney. Trademark trolls gonna troll, after all.
