You can get all kinds of fancy lenses for modern cameras, with all sorts of mechanical and electronic wizardly to make them shoot better images. But what if you paired a vintage lens with a modern camera? It would take some work, as [Mathieu] found out, but you’d also get some interesting results.

The optic in question is a 100-year old lens—a Foth 50 mm f2.5 to be precise, originally used with a folding film camera. It was sourced from a market for just 3 euros. Notably, the lens was not designed for modern cameras, and so lacks an aperture and focusing mechanism. [Mathieu] thus had to fabricate something to fit the lens to a Sony FX3. A first attempt used an aperture adapter from Amazon and an elcoid adapter, but there were vignetting problems due to the lens placement in this case. Ultimately, [Mathieu] went with a special macro adapter that allowed him to control focus and tuck in an ND filter behind the lens, which made up for the lack of an aperture.

The vintage glass isn’t the sharpest lens out there, but that’s kind of what’s fantastic about it. The center of the frame is certainly focused, but it fades out softly towards the edges of the image, giving a cinematic, dreamlike effect. The bokeh in the background are particularly charming, too. As far as 3 euro lenses go, this one was a hit.

You can slap just about any lens on anything if you get creative with how you do it. Video after the break.

Continuing his quest to put DOOM on literally everything that has a capable enough processor and a screen, [Aaron Christophel]’s most recent target is a Slate 7 Pro travel router. With a generous 2.8″ touch screen and a lot of onboard processing power to handle all the advertised networking and routing features via its WAN and (W)LAN interfaces, it should be able to run the game really quite well. As usual the main question is how to get the game to run on it first.

The port of choice is fbdoom, with instructions on how to run it on this router provided on the GitHub project page. The reason for the touch screen is so that you can see the status of interfaces and interact with it without having to open the web interface. Boringly, this router has an SSH daemon ready to connect to, giving you full root access to the Linux-based firmware.

It’s just your typical AArch64 ARM-based system, with the gl_screen process running for the touch screen display. From there it was easy enough to deduce the settings to jot into fbdoom so that it too could use the same screen and touch inputs. After copying the compiled binary with SCP over to the router, it can then be started like any application. With touch inputs somewhat awkwardly mapped to certain areas of the touch screen, it’d be nice to see the USB 2.0 port used for USB HID inputs, but it does show how easy things can be when it runs something like Linux and you got full root access.

Incidentally this also heavily blurs the lines between something like a Valve Steamdeck and a router, with the latter just missing some gamepad controls on the side to do some on-the-go gaming when you’re not using it for routing network traffic.

Phones can be distracting objects if you’re not an enlightened master of the mental arts. Even just reading an email or glancing at your calendar can get you caught up checking other apps and notifications and waste your time. [Paul Lagier] built a device to eliminate this problem by showing him critical information right on his desk.

The device is based around an off-the-shelf Waveshare ESP32 board which packs in a small 8×8 RGB LED matrix on one side. It’s a neat way to get an LED project up and running quickly, but [Paul] noted that it didn’t look that great out of the box. He had to experiment with some different solutions for diffusing the light, eventually wrapping the board in a 3D printed housing with a black grid to separate the light output from each LED to make a clear pixelated display.

The ESP32’s wireless connectivity comes in handy, because it’s able to query web services for [Paul’s] calendar and other useful data. The user interface is minimal—you merely flip the housing into a different orientation to display different information, relying on the onboard QMI8658 6-axis sensor. The main display shows [Paul’s] calendar in 15 minute blocks so he can keep track of meetings without having to open his phone. Shaking the device in this mode will display the events as scrolling text. There’s also an ambient mode that looks pretty, and a pairing mode for setting up the wireless connectivity.

The great thing about modern electronic hardware is that it’s very easy to produce productivity aids like this to suit your own lifestyle.

One doesn’t generally associate cardboard with structural components like hinges, but [Itoshige Studio] assures us that you can absolutely create hinges out of this ubiquitous material. In total the video covers five different designs, ranging from the simple and straightforward to an interlocking tab design that approximates a typical steel hinge with paper rod to keep both sides of the hinge together.

The most simple hinge is unsurprisingly just a strip of craft paper, which is also demonstrated as the hinge for a wooden box in lieu of the typical metal hinge. This same principle is then demonstrated for a fancy cardboard box.

From here the hinge designs increasingly get more involved, with first a seamless hinge variation, and then a kamichoban hinge design that’s inspired by traditional Japanese room dividers and furniture, using panels that are interconnected with overlapping sections to create a fascinatingly flexible hinge that can fully fold either way.

The flush hinge design is somewhat like the craft paper hinge, but significantly fancier and probably sturdier, while also looking pretty good on something like a cabinet. Finally the interlocking tab hinge is effectively a cardboard version of the hinge design that’s found on every room’s door, with a similar level of flexibility. This is obviously the trickiest one to assemble and get right, but it has its own charm.

Considering that all of these examples use regular corrugated cardboard that we get shipped to our homes by the truckload, the cost to try these examples is your time plus some basic tools and glue. The author also sells a book that contains templates – in addition to digital versions – for these hinges and other designs, if you’d like to enjoy the 100% paper experience.

The Osmo Pocket 4 is a handheld gimballed camera that’s perfect for shooting running content on the go. However, it’s got a weird sort of form factor and is limited when it comes to things like fitting filters or recording quality sound. To that end, [Byron Seven] whipped up an upgrade kit that turns the Pocket 4 into more of a “real” camera.

The idea is simple enough—the Osmo Pocket 4 is packaged in a 3D printed shell that expands its capabilities. It’s tucked into the structure with a USB power bank that greatly increases how long you can shoot before the batteries run out. In front of the gimbal head, there’s a fitting that allows attaching standard camera filters for visual effect. Topside there’s a handle for better physical control of the camera, along with a rail mount for a DJI wireless mic and a phone to act as a monitor. Down below, there’s a quick-connect fitting so the camera can be slammed on and off a tripod with ease. What’s great is that you can slot a Pocket 4 into this rig when you need, and pull it back out and use it as normal when you’re done.

If you’ve enjoyed the Osmo Pocket 4 but wished you could throw a polarizer on it or chuck it around more, this is a great build to explore. We’ve seen some fun stuff done with non-traditional cameras before, too.

We’re used to seeing technologies move with the times, and it’s likely among Hackaday readers are the group who spend the most time doing that and are most aware of it. There’s one which we’ll all be aware of which has quietly slipped away for most of us almost without a word, I speak of course of 32-bit computing. For most of us that means 32-bit computing on x86 machines, and since the 64-bit x86 instruction set we all now use has been around for nearly a quarter century, its 32-bit ancestor is now ancient history.

In the world of software that means we’re now in an era of operating systems and browsers dropping 32-bit support, so increasingly keeping a 32-bit machine up to date will become a challenge. That sounds like something just painful and difficult enough to subject to a Daily Drivers piece, so just how practical is it to use a 32-bit machine for my daily work in 2026?

2005 Just Gave Me A Computer

On my desk I have a Dell Latitude D610. It was made in about 2005 in the days when Dells were solidly made, and with its 1.6GHz Pentium M and 2Gb of memory it represents roughly the final throw of the dice for a 32-bit Intel laptop. Just over a year later it would have been replaced by one of the Intel Core series with the 64-bit instructions grudgingly adopted from AMD, but at the time it was a respectably useful machine.

It came into my possession about eight years ago when I used it to test the Revbank bar tab software for my hackerspace, and for the past six years it’s languished unloved in my box there. It’s got an ancient Ubuntu distro on it, so my first task is to pick a 32-bit replacement from 2026. That’s now a dwindling selection, so it’s time to start digging though some minimalist distros. With the supply of those based on mainstream distros drying up as they drop 32-bit support, it’s time to look into more esoteric offerings. This fits well with the ethos of this series, we’re all about the unusual here.

Cutting out the mainstream based distros certainly narrows the field, and out of the promising contenders in the minimalist field, I went for SliTaz. It uses Busybox and the Openbox desktop, that runs from RAM. I was looking for good application support in the repos, and this distro has the things I need. Download it, stick it on a USB stick, and let’s see what it can do. I know one thing, I wouldn’t have been able to download that ISO in five seconds with the internet connection I had in 2005.

SliTaz, A Tiny Distro That’s Really Useful

With a few of the type of quirks you’ll always encounter with a new distro, the SliTaz instllation process was pretty painless. It required me to use Gparted to partition the spinning rust on the Dell, but otherwise the installation was mostly a case of filling in standard responses you’d find on any distro. Then it’s into the Openbox desktop environment. This thing is fast!

Graphical system administration is done through the Tazpanel application that as far as I can see uses the web browser, which soon had me connected to the internet and downloading GIMP so I could do my Hackaday work. The package library is comprehensive, which is pleasing to see. The default web browser is called Tazweb, which is modern enough to render most the sites I normally use, but which for some reason didn’t like Hackaday’s WYSIWYG editor so I was left writing in HTML source. It is quick though on this older hardware, something brought home to me when I downloaded Pale Moon. That browser is usable, but noticeably slow.

This was the first time using SliTaz for me, and I have to say I’m impressed. It’s small and fast compared to other full-fat distros I’ve used on machines of this age, and quirks aside, it’s easy to use and seems well supported. I’ve written most of this piece on it, and unlike some of the previous operating systems in this series, that has not been a painful experience. It has made the Dell into a useful machine again, one which while it’s no powerhouse, is at least no longer a piece of e-waste. There’s also a 64-bit version, making it a good choice for newer old hardware too. (The Raspberry Pi 1 port looks particularly interesting.)

Should You Though, Really?

So what have I proved here? A 21 year old 32 bit machine is a bit slow but still usable here in 2026 with the right software, which is to my mind a testament to the skill and dedication of open source developers and maintainers for keeping this ancient architecture alive. Researching this piece though it’s very obvious that much of the software necessary for modern computing is slipping out of 32 bit support, so I have to question how much longer they can keep it up. Considering that this machine has about the same intrinsic monetary value as a Core2-based machine made a little over a year later which supports 64 bit code I have to concede that what I’ve just done is a fairly pointless exercise. It’s necessary to keep old hardware usable as long as possible, but when it’s lasted over two decades as this one has them maybe we should concede that it’s time to move on. Find a 64-bit laptop from 2007, by all means install 64-bit SliTaz if you want a quick and small distro, and move forward with many more years of software support.

In a way the real star of this piece is the Dell itself. It was a corporate laptop, then as far as I know it was used by the Men In Sheds that shares the building with MK Makerspace, and when they tossed it I nabbed it to play with RevBank. Saved by a piece of Dutch open source software it’s sat unloved for years, and yet it’s still reliable, its battery still holds almost useful charge, its keyboard is robust if a little worn, and its joints are still tight. It’s a shame the architecture is sliding out of relevance, this is almost a useful laptop!

Odd things sometimes pop up in the feed of a Hackaday scribe, not hacks as such, but stories with a meaning in our community. One such that’s come our way from a variety of sources over the last week features Ursa Ag, a small machinery manufacturer based in Alberta, Canada. The reason they’re in the news is because they have gained bulging order books by taking on the likes of John Deere with a tractor more like the one their customers’ parents bought back in the ’80s or ’90s. It’s a basic machine without much in the way of electronics, and certainly without all the DRM lockdown that has made those big manufacturers so unpopular.

It’s clear that Hackaday isn’t in the business of shilling Canadian tractors, but it should be of interest to readers because it represents an alternative route to challenge the DRM lockdowns than the legal and consumer routes we’ve previously reported on. The Ursa Ag tractor may be as niche Albertan as a Corb Lund CD, but it’s not the tractor itself but the idea which matters. We doubt much sweat will be shed by John Deere execs over a tiny company out on the prairies making a basic spec tractor, but given that Ursa Ag customers are reported as buying them because they have no DRM, the prospect of larger upstart competitors taking note and offering machines without it may cause them some sleep loss. The free market is held up to outsiders as perhaps the most American of ideals, and for it to eventually prove to be the means by which something intended to limit it might be defeated, is sweet justice indeed.

We’ve reported extensively on the Deere tractor saga over the years, but perhaps the best illustration of the self-inflicted damage the brand has suffered through DRM comes in their older products being worth considerably more than their newer ones.
