Same As It Ever Was

August 29, 2026 by 96 Comments

Whether you like it or not, the use of LLMs to write code is kind of a big deal at the moment. We’ve been asking ourselves what, if anything, this means for us here at Hackaday. Should we try to figure out what percentage of a project was done by an actual human and how much was done by a machine? Does it really matter? What is our AI policy anyway?

Clearly, Hackaday is pro-human. We’re in it for the hackers as much as for the hacks. Our community is, like Soylent Green, made of people. It’s your inspirations and innovations that keep us reading and writing every day. And we produce 100% of our content the old-fashioned way, with projects selected through the taste and judgement of our writers, and their own words telling the story.

What about the hacks? We’ve seen a lot of projects recently that were coded with the help of an LLM. Does that diminish the work? In the end, what rings truest to us is what has always been Hackaday’s editorial guiding star: Is there something special in the hack that makes it worth talking about? Then we write about it. Was it written using vim or emacs? Did the author consult friends or a chatbot while working on the project? That’s not really relevant.

But in the past few years, the BS-generation machines have found our hobby, and we’re finding a lot more projects that don’t have any spark to them. We’re seeing circuits that make no sense, and claims that defy physics. Of course, we always have. The LLM-nonsense project is today’s version of the perpetual motion machines of old. Just like we never trust a hardware project that is all renders, seeing only AI-generated images is a huge red flag. It’s our job to separate out the wheat from the chaff for you all, but it’s something that you must be doing everyday as well.

We’ve seen amazing hacks over Hackaday’s 22-year history. Hackaday is older than YouTube and older than Stack Overflow. We’ve seen technology come and go. We’ve seen C-beams glitter in the dark near the Tannhäuser gate. (OK, maybe not.) And in the end, our AI policy is our same-old policy: we write up hacks that inspire us in the hope that they inspire you.

So if you’re using Claude to help you with the UI bits, or if you’re hand-writing it all in assembly, or wiring up the logic in diodes, we just want to see your cool hacks. And we hope that our collective signal will be so loud that we drown out the noise, at least in our own little corner of the hacker universe.

Hackaday Podcast Episode 384: OCR MOD Records, Magical PCBs, And The Gravity Of Space Stations

August 28, 2026 by 1 Comment

What did Hackaday editors Elliot Williams and Al Williams read in Hackaday last week? Probably everything, but you can tune in and hear about their favorites on this week’s podcast. They heard from lots of listeners this week, and also saw DIY projects running from a 3D-printed Stirling engine, to clogs, to LEDs.

There are some over-the-top hacks like a refit for a decades-old watch to do tap-to-pay and a — for lack of a better word — a record player that optically reads MOD files. Want to emulate an iPod? Talk to Eliza? Print a hand-operated rail car? Hackaday is the place to read about it all.

The can’t miss articles included a talk from Hackaday Europe about making magical PCBs and a not-so-brief history of space stations starting in the 1800s.

Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments!

This Week In Security: Android Malware, VOIP Hijack, Signal Contact Discovery, And TeamPCP Arrests

August 28, 2026 by 4 Comments

On GitHub, [AyaanB] details buying a cheap Android TV streaming device, looking for, and finding, baked-in malware.

Multiple warnings have been issued by the FBI and CISA regarding malware on media box Android devices. Many devices have been caught participating in botnets providing residential proxies, ad-click fraud, and DDOS services. [AyaanB] sets out to discover if a $30 set-top streaming box is pre-infected with malware, and extracting it – without ever letting the device talk to the Internet or access other devices on the local network.

Picking a device named in the advisories, [AyaanB] discovered that it was, indeed, preloaded with multiple app stores and applications that wouldn’t typically make sense on a set-top TV box. After identifying the serial port test pads and obtaining a low-voltage serial adapter, they were able to gain access to the bootloader and from there dump the contents of the MMC over TFTP.

With the entire filesystem accessible out-of-body, proving it was infected with malware at the factory becomes simple: the malware is signed as a system application, baked onto the system partition of the MMC, granted SELinux exceptions to mark it as a system binary with shell privileges, and has multiple launch scripts to make sure it is executed even if partially removed. With the malware identified, [AyaanB] continues to dig through to uncover the capabilities.

By installing hooks into the low-level Android process spawning system, the malware installs hooks into every application as it is launched: even if an application isn’t trojaned already, by the time it finishes executing, it’s definitely been subverted. The functions patched and the methods used match the Vo1d botnet, which is used for account takeovers, residential proxies, free “VPN” services, and other unfriendly behavior.

Further digging into the system showed hooks for ad-click fraud, where hidden browser windows are allowed to run unthrottled and display overlays are configured to obscure ads below where the user may click. Other included tools bid in real-time ad auctions, claiming to directly publish ads to the user which may or may not be visible. To cap it all off, a root level backdoor allows botnet operators to access the systems directly and install additional tools.

Be sure to check out [AyaanB]’s writeup for more details on exfiltration methods and other malware found on the devices. Continue reading “This Week In Security: Android Malware, VOIP Hijack, Signal Contact Discovery, And TeamPCP Arrests” →

AI Book Scanning: Just What Is A Rare Book?

August 25, 2026 by 112 Comments

One of the stories of the last few weeks has been that AI companies have been scanning books in very large numbers in order to train their models with content guaranteed to have been written before 2002, and thus AI free. It’s caused some outrage, because of the size of the operation, and because the scanning process is destructive. In particular the phrase being bandied around is that these are rare books, and it’s this phraseology I find problematic. I think it’s time to unpack why that is the case.

It’s Not Book Burning, Folks

Before I worked for Hackaday I had a long career in and around the publishing industry, mostly on the electronic side, but from time to time crossing paths with my colleagues in the world of paper-based publishing. I understand the appeal of a good book, I’ve spend a lot of my life among bibliophiles, and let’s just say I own a few books myself. In particular I understand the symbolism of destroying books, bringing to mind as it does the actions of repressive regimes. I have stood in Bebelplatz in Berlin where the photo of Nazi student organisation members burning the library of Magnus Hirschfeld’s institute was taken in 1933, and if you know me, you’ll have an idea why that’s close to home. But for all that, what the AI companies are doing is not the same thing.

In this case they’re destroying the books for two reasons. Firstly, as I remember from a previous employer in the publishing world, it’s much easier to digitise a stack of papers than it is a bound book. Thus I’m pretty sure that’s one reason they remove the binding before digitising the pages. Then secondly, as I understand it it’s a copyright issue. If they buy a book, digitise it, and destroy the physical copy, they can legitimately claim that only one copy of it exists, and they hope, sidestep copyright claims from publishers.

Tech In Plain Sight: Vacuum Blood Collection

August 24, 2026 by 36 Comments

If you’re blessed enough that you haven’t had blood drawn in a while, you might not have thought much about the process. You might imagine that a needle goes in, a syringe is drawn back, and the venous blood is thusly collected. Indeed, it can be done that way.

However, there is an altogether niftier and more efficient method of fast blood collection for pathology testing. It’s all about using vacuum and smart design to ease the work of phlebotomists, while maintaining a sterile and safe environment.

Hackaday Links: August 23, 2026

August 23, 2026 by 1 Comment

We’ll start this week off with some disappointing, though not entirely unexpected, news — the ambitious commercial mission to save NASA’s Neil Gehrels Swift Observatory is officially a bust. The space agency provided an update earlier this week explaining that the attitude control issues with the LINK spacecraft that started a few weeks after it launched will prevent it from being able to safely dock with the Swift Observatory and boost its altitude. As such, the space telescope is now expected to reenter the Earth’s atmosphere and burn up before the end of the year.

Although LINK won’t be able to live up to its name, NASA did say operator Katalyst Space has been given permission to continue with the rendezvous attempt. The two craft won’t actually make contact with each other, but teams on both sides feel there’s lessons to be learned and data to be collected by seeing the orbital dance of these two vehicles play out for as long as possible.

Speaking of hardware that couldn’t quite hit its design goals, TechCrunch is reporting that a class action lawsuit has been filed against Oura by customers that say the company made misleading claims about the sleep-tracking accuracy of their smart rings. Namely, that the rings could somehow detect which stage of sleep the wearer was in with only the pulse and temperature sensors it has onboard.
