I love, love, love Saturn by [Rain2], which comes in two versions. The first, which is notably more complex, is shown here with its rings-of-Saturn thumb clusters.
Saturn has one built right in. The basic idea was to add a num pad while keeping the total number of keys to a minimum. Thanks to a mod key, this area can be many things, including but not limited to a num pad.
As far as the far-out shape goes, and I love that the curvature covers the thumb cluster and the index finger, [Rain2] wanted to get away from the traditional thumb cluster design. Be sure to check out the back of the boards in the image gallery.
Unfortunately, this version is too complicated to make, so v2 does not have the cool collision shapes going for it. But it is still an excellent keyboard, and perhaps will be open source someday.
Say hello to Phanny, a custom 52-key wireless split from [SfBattleBeagle]. This interestingly-named board has a custom splay that they designed from the ground up along with PCBWay, who sponsored the PCBs in the first place.
While Ergogen is all the rage, [SfBattleBeagle] still opts to use Fusion and KiCad, preferring the UI of the average CAD program. If you’re wondering about the lack of palm rests, the main reason is that [SfBattleBeagle] tends to bounce between screens, as well as moving between the split and the num pad. To that end, they are currently designing a pair of sliding wrist skates that I would love to hear more about.
Be sure to check out the GitHub repo for all the details and a nice build guide. [SfBattleBeagle] says this is a fun project and results in a very comfy board.

I must say, the Antikey Chop doesn’t have much to say about the Masspro typewriter, and for good reason.
But here’s what we know: the Masspro was invented by a George Francis Rose, who was the son of Frank S. Rose, inventor of the Standard Folding Typewriter. That machine was the predecessor to the Corona No. 3.
Frank died right as the Rose Typewriter Co. was starting to get somewhere. George took over, but then it needed financing pretty badly.
Angel investor and congressman Bill Conger took over the company, relocated, and renamed it the Standard Folding Typewriter Co. According to the Antikey Chop, “selling his father’s company was arguably George’s greatest contribution to typewriter history”.
George Rose was an engineer like his father, but he was not very original when it came to typewriters. The Masspro is familiar yet foreign, and resembles the Corona Four. Although the patent was issued in 1925, production didn’t begin until 1932, and likely ended within to years.
Why? It was the wrong machine at the wrong time. Plus, it was poorly built, and bore a double-shift keyboard which was outdated by this time. And, oh yeah, the company was started during the Depression.
But I like the Masspro. I think my favorite part, aside from the open keyboard, is the logo, which looks either like hieroglyphics or letters chiseled into a stone tablet.
I also like the textured firewall area where the logo is stamped. The Antikey Chop calls this a crinkle finish. Apparently, they came in black, blue, green, and red. The red isn’t candy apple, it’s more of an ox-blood red, and that’s just fine with me. I’d love to see the blue and green, though. Oh, here’s the green.
Okay, so Keychron’s new Nape Pro mouse is pretty darn cool, and this is the best picture I could find that actually shows how you’re supposed to implement this thing on your desk. Otherwise, it looks like some kind of presentation remote.
So the idea here is to never take your hands off the keyboard to mouse, although you can use it off to the side like a regular trackball if you want. I say the ability to leave your fingers on the home row is even better.
There are plenty of keyboards with trackpads and other mousing functions that let you do this. But maybe you’re not ready to go that far. This mouse is a nice, easy first step.
The ball is pretty small at 25 mm. For comparison, the M575 uses a 34 mm ball, which is pretty common for trackball mice. Under those six buttons are quiet Huano micro switches, which makes sense, but I personally think loud-ish mice are nice enough.
I’ve never given it much thought, but the switches on my Logitech M575 are nice and clicky. I wonder how these compare, but I don’t see a sound sample. If the Nape Pro switches sound anything like this, then wowsers, that is quiet.
The super-cool part here is the software and orientation system, which they call OctaShift. The thing knows how it’s positioned and can remap its functions to match. M1 and M2 are meant to be your primary mouse buttons, and they are reported to be comfortable to reach in any position.
Inside you’ll find a Realtek chip with a 1 kHz polling rate along with a PixArt PAW3222 sensor, which puts this mouse in the realm of decent wireless gaming mice. But the connectivity choice is yours between dongle, Bluetooth, and USB-C cable.
And check this out: the firmware is ZMK, and Keychron plans to release the case STLs. Finally, it seems the mouse world is catching up with the keyboard world a bit.
Got a hot tip that has like, anything to do with keyboards? Help me out by sending in a link or two. Don’t want all the Hackaday scribes to see it? Feel free to email me directly.

Although there are a few hobbies that have low-cost entry points, amateur astronomy is not generally among them. A tabletop Dobsonian might cost a few hundred dollars, and that is just the entry point for an ever-increasing set of telescopes, mounts, trackers, lasers, and other pieces of equipment that it’s possible to build or buy. [Thomas] is deep into astronomy now, has a high-quality, remotely controllable telescope, and wanted to make it more accessible to his friends and others, so he built a system that lets the telescope stream on Twitch and lets his Twitch viewers control what it’s looking at.
The project began with overcoming the $4000 telescope’s practical limitations, most notably an annoyingly short Wi-Fi range and closed software. [Thomas] built a wireless bridge with a Raspberry Pi to extend connectivity, and then built a headless streaming system using OBS Studio inside a Proxmox container. This was a major hurdle as OBS doesn’t have particularly good support for headless operation.
The next step was reverse engineering the proprietary software the telescope uses for control. [Thomas] was able to probe network traffic on the Android app and uncovered undocumented REST and WebSocket APIs. From there, he gained full control over targeting, parking, initialization, and image capture. This allowed him to automate telescope behavior through Python scripts rather than relying on the official Android app.
To make the telescope interactive, he built a Twitch-integrated control system that enables viewers to vote on celestial targets, issue commands, and view live telemetry, including stacking progress, exposure data, and target coordinates. A custom HTML/CSS/JavaScript overlay displays real-time status, and there’s a custom loading screen when the telescope is moving to a new target. He also added ambient music and atmospheric effects, so the stream isn’t silent.
If [Thomas]’s stream is your first entry point into astronomy and you find that you need to explore it more on your own, there are plenty of paths to build your way into the hobby, especially with Dobsonian telescopes, which can be built by hand, including the mirrors.

Carbon fiber (CF) has attained somewhat of a near-mystical appeal in consumer marketing, with it being praised for being stronger than steel while simultaneously being extremely lightweight. This mostly refers to weaved fibers combined with resin into a composite material that is used for everything from car bodies to bike frames. This CF look is so sexy that the typical carbon-fiber composite weave pattern and coloring have been added to products as a purely cosmetic accent.
More recently, chopped carbon fiber (CCF) has been added to the thermoplastics we extrude from our 3D printers. Despite lacking clear evidence of this providing material improvements, the same kind of mysticism persists here as well. Even as evidence emerges of poor integration of these chopped fibers into the thermoplastic matrix, the marketing claims continue unabated.
As with most things, there’s a right way and a wrong way to do it. A recent paper by Sameh Dabees et al. in Composites for example covered the CF surface modifications required for thermoplastic integration with CF.
There are a number of ways to produce CF, often using polyacrylonitrile, rayon, or pitch as the feedstock. After spinning this precursor into a suitable filament, heating induces carbonization and produces the carbon fiber.
Following this process, the CF is typically in the form of a few micrometer-thick fiber that is essentially pure carbon. To create a structural interface between the CF and the polymer of a composite material, some kind of process has to take place that creates this interface.
The fundamental difference between thermoset and thermoplastic polymers is that thermoset polymers are reacting in the mold as it sets, providing an environment in which the epoxy precursor and hardener can interact with the normally not chemically very reactive CF to form covalent bonds.
In comparison, thermoplastic polymers are already finalized, with covalent bonds between thermoplastics and CF unlikely. This means that the focus with CF-reinforced thermoplastics is mostly on weaker, non-covalent interactions, such as Van der Waals forces, pi-interactions and hydrogen bonds. Each of these interactions is further dependent on whether the thermoplastic is compatible, such as the presence of aromatic rings for pi-interactions.
With those challenges in mind, how can thermoplastics be coaxed into forming a significant interface with CF? As noted in the earlier cited work by Sameh Dabees et al., there is no single surface treatment for CF that would work for every thermoplastic polymer, as a logical result of the limitations imposed by the available non-covalent interactions.
One way to prepare the CF is by apply a coating to the fiber, called a sizing. By applying a sizing to the fiber that is compatible with the target thermoplastic, the interface with the bulk material is expected to improve. In one cited study involving a polyamide-acid sizing for polyimide bulk material, this coating created an approximately 85 nm interface, with an interfacial shear strength increased by 32.3%. In another study targeting CF-PEEK, this had a polyimide-based, water-soluble sizing applied that also significantly improved the shear strength.
Of course, this sizing has to actually adhere to the CF, lest it simply vanishes into the bulk thermoplastic material. This is a problem that is easily observable in FDM-printed thermoplastic polymers as distinct voids around the CF where the bulk polymer pulled away during crystallization, and no interface formed. Obviously, these voids create a weak point instead of strengthening the material.
Although CF is often confused with carbon nanotubes, it does not have the rigidly ordered structure that they do. Instead it has a graphite structure, owing to the way that they are produced, meaning sheets of graphite placed together in a disordered fashion. Despite this, the external surface is still smooth, which is where the chemical inertness comes from. Combined with the lack of reactivity from the side of thermoplastics, this highlights the need for something to bridge the gap.
The review paper by Dabees et al. covers the most common types of surface treatments, with the above graphic providing a summary of the methods. Perhaps one of the most straightforward methods is the coating of the CF with an epoxy, thus shifting the interface from CF-thermoplastic to thermoset-thermoplastic. This kind of hybrid approach shows promising results, but is also cumbersome and not a universal fix.
Note that virtually all research here is focused on thermoplastic polymers like polycarbonate and PEEK, as these are most commonly used in industrial and medical settings. Yet even within that more limited scope the understanding of the exact effects of these modifications remains poorly investigated. Much of this is due to how hard it is to characterize the effects of one treatment when you take all other variables into account.
Perhaps most frustrating of all is how hard it is to research this topic considering the scale of the CF surface and the miniscule thickness of the CF-polymer interface. Relying on purely mechanical tests to quantify the impact is then tempting, but ultimately leaves us without a real understanding of why one method seems to work better than another.
The overall conclusion that we draw from this particular review paper is that although we know that composite materials can often provide improvements, in the case of thermoplastic-CF composites we realize that our understanding of the fundamentals is still rather lacking.
Outside of the less mainstream world of industrial and medical settings, CF is now widely being added to thermoplastic polymers, primarily in the form of filaments for FDM 3D printers. Without detailed information on whether the manufacturers of these filaments perform any kind of CF surface modification, it is very hard to even compare different CF-polymer filaments like this, even before taking into account individual FDM printer configurations and testing scenarios.
Considering that CF has for a few years now been identified as a potential carcinogen akin to asbestos, this raises the question of whether we really want to put CF and particularly the very small chopped carbon fibers into everything around us and thermoplastics in particular. When the empirical evidence available to us today shows that any mechanical improvements are not due to a solid CF-polymer interface, and any potential carcinogenic risks still years into the future of becoming clear, then the logical choice would be to hold back on CF-thermoplastics until we gain a better understanding of the benefits and risks.

Over the past years, the author of the cURL project, [Daniel Stenberg], has repeatedly complained about the increasingly poor quality of bug reports filed due to LLM chatbot-induced confabulations, also known as ‘AI slop’. This has now led the project to suspend its bug bounty program starting February 1, 2026.
Examples of such slop are provided by [Daniel] in a GitHub gist, which covers a wide range of very intimidating-looking vulnerabilities and seemingly clear exploits. Except that none of them are vulnerabilities when actually examined by a knowledgeable developer. Each is a lengthy word salad that an LLM churned out in seconds, yet which takes a human significantly longer to parse before dealing with the typical diatribe from the submitter.
Although there are undoubtedly still valid reports coming in, the truth of the matter is that the ease with which bogus reports can be generated by anyone who has access to an LLM chatbot and some spare time has completely flooded the bug bounty system and is overwhelming the very human developers who have to dig through the proverbial midden to find that one diamond ring.
We have mentioned before how troubled bounty programs are for open source, and how projects like Mesa have already had to fight off AI slop incidents from people with zero understanding of software development.

If you’re reading this, you probably have some fondness for human-crafted language. After all, you’ve taken the time to navigate to Hackaday and read this, rather than ask your favoured LLM to trawl the web and summarize what it finds for you. Perhaps you have no such pro-biological bias, and you just don’t know how to set up the stochastic parrot feed. If that’s the case, buckle up, because [Rafael Ben-Ari] has an article on how you can replace us with a suite of LLM agents.
He actually has two: a tech news feed, focused on the AI industry, and a retrocomputing paper based on SimCity 2000’s internal newspaper. Everything in both those papers is AI-generated; specifically, he’s using opencode to manage a whole dogpen of AI agents that serve as both reporters and editors, each in their own little sandbox.
Using opencode like this lets him vary the model by agent, potentially handing some tasks to small, locally-run models to save tokens for the more computationally-intensive tasks. It also allows each task to be assigned to a different model if so desired. With the right prompting, you could produce a niche publication with exactly the topics that interest you, and none of the ones that don’t. In theory, you could take this toolkit — the implementation of which [Rafael] has shared on GitHub — to replace your daily dose of Hackaday, but we really hope you don’t. We’d miss you.
That’s news covered, and we’ve already seen the weather reported by “AI”— now we just need an agenetic sports section and some AI-generated funny papers. That’d be the whole newspaper. If only you could trust it.

[Bhaskar Das] has been tinkering with one of Nintendo’s more obscure handhelds, the DSi. The old-school console has been given a new job as part of an augmented reality app called AetherShell.
The concept is straightforward enough. The Nintendo DSi runs a small homebrew app which lets you use the stylus to make simple line drawings on the lower touchscreen. These drawings are then trucked out wirelessly as raw touch data via UDP packets, and fed into a Gemini tool which transforms them into animation frames. These are then sent to an iPhone app, which uses ARKit APIs and the phone’s camera to display the animations embedded into the surrounding environment via augmented reality.
One might question the utility of this project, given that the iPhone itself has a touch screen you can draw on, too. It’s a fair question, and one without a real answer, beyond the fact that sometimes it’s really fun to play with an old console and do weird things with it. Plus, there just isn’t enough DSi homebrew out in the world. We love to see more.
