Hackaday Europe 2026: Open Source Hardware Goes Underground, Literally

August 17, 2026 by Tom Nardi No comments

These days open source is everywhere, and frankly, we couldn’t be happier about it. But even with as prevalent as open software and hardware has become, we still occasionally hear about a project that takes the concept somewhere unexpected. Which is precisely why we were so eager to hear more about the fascinating work [Phil Underwood] has been doing.

In his talk Open Source Caving: 20 Years of Making Cave Mapping Tools at Hackaday Europe 2026, [Phil] takes us through a series of progressively more advanced open hardware devices that he’s designed to increase the speed and accuracy of underground mapping efforts. Along the way, he’s learned a number of valuable lessons about designing hardware that’s robust enough to handle the uniquely challenging environment underground while still being accessible enough for a hobbyist to build and use.

We’re no strangers to unusual hardware failures around these parts, but even so, a swarm of jellyfish clogging up the works is a new one to us. That’s exactly what happened to the cooling system at the Gravelines nuclear power plant in France earlier this week, resulting in three reactors having to be shut down. This isn’t even an isolated incident, as POLITICO points out that the same thing actually happened last year around this same time.

So why are jellyfish staging an annual protest against nuclear power? A warming of the North Sea has extended breeding seasons and produced larger populations of the plankton that the jellyfish feed on. This is great for the gelatinous sea creatures, but not exactly ideal if you’re trying to pump the water they live in through a complex cooling system. The French installed filter screens and monitoring systems after this happened in 2025, but clearly they’re going to need to keep working on the problem.

From a new problem to a very old one, a BBC investigation has revealed that the UK’s National Health Service (NHS) Blood and Transplant department was inadvertently leaking private patient data by sending it in the clear over the pager network. Sniffing pager messages was fairly trivial decades ago, and is even easier these days thanks to the proliferation of cheap software-defined radios and open source decoding software. Given the fragility of the underlying communication network they use, the NHS announced they were going to stop using pagers by 2021, but clearly not everyone got the memo.

Bad news for anyone who was hoping for some relief from the memory shortage — Digitimes is reporting that the production capacity of major players such as Samsung, Micron, and SK Hynix has already been booked for 2027 due to record demand. Their industry sources indicate that what we’re experiencing currently is just a prelude to when things get really ugly, which is why customers are paying a premium to lock in their orders so far out.

Although there’s been no official word from either side of the transaction, the Digitimes article further points out that these sort of agreements are usually 3 to 5 year contracts. If that’s the case, and nothing changes in supply and demand equation, we could be in for a very rough ride. There’s a potential opportunity here for other manufacturers to step in and start producing DRAM, possibly even focusing on lower-performance offerings intended for the consumer market, but setting up those production lines isn’t going to happen overnight. It’s always possible the AI bubble could pop in the next couple of years, but we’re not sure we’d put money on it.

There’s a developing story this weekend about the breach of customer data over at Framework. The maker of modular and repairable computers has recently sent an email out to all customers that their names, email addresses, phone numbers, and physical addresses were leaked due to an upstream zero-day attack against database provider Metabase.

Metabase disclosed the breach on August 3rd, but we were mildly surprised to see that Framework doesn’t seem to have made any public acknowledgement of the event so far. As far as we can tell, the only reason there are copies of the email from them circulating online is because several customers posted it to social media. In their statements to sources such as TechCrunch, Framework reps were also hesitant to give hard details such as how many customers were impacted. While we’re fans of what Framework is trying to do in terms of hardware customization and repairability, we have to admit that being cagey about this sort of thing isn’t a good look.

Phantomdrive Keeps Your Secrets Out Of Sight

August 6, 2026 by Tom Nardi 15 Comments

It’s a complex world out there, and more than ever folks may find themselves in a situation where they want to keep particular bits of information away from prying eyes. At the same time, overly complex methods of file security can make it difficult to share said information with the intended recipients impractical. So what’s the solution?

One proposal from [Ryan Walker] AKA [machinehum] is the Phantomdrive — a fully open source USB flash drive that features a secret secondary filesystem. Not only is the existence of this data hidden from the operating system under normal circumstances, but it’s encrypted with AES-256. Rather than relying on software running on the computer to handle the decryption, the CH569 chip that powers the drive does it internally.

To complete this platform-agnostic approach, [machinehum] had to come up with a way for the user to unlock the secure storage that didn’t require running any code on the client machine. A hardware solution such as a keypad is the obvious answer, but in this case, was out of the question as it would immediately tip off an observer about the drive’s true nature. A covert storage device needs a similarly inconspicuous method of authentication.

That’s why the firmware on the Phantomdrive keeps an eye on all the write operations to the unsecured section of the drive looking for the string password:. Once it sees that, it treats whatever follows as the decryption key. If it’s correct, the previously inaccessible data will appear to the operating system as a new drive.

[machinehum] cautions that none of this has been professionally audited from a security standpoint, and that you should treat this whole concept as an experiment. In other words, it’s probably more than sufficient for the average person, but no guarantees on how long it would last should a three letter agency gets too interested in what you’re up to.

If this seems a bit familiar, it’s because the Phantomdrive follows up [machinehum]’s self-destructing USB flash drive from a few years back. The concept is essentially the same, except this time there’s no Magic Smoke getting released.

About a month ago, we brought you word that the commercial rescue mission designed by Katalyst Space to save NASA’s Swift gamma-ray observatory had reached orbit and early indicators were looking good. Unfortunately, it didn’t take long for things to start going sideways, and up until very recently, the situation seemed pretty dire. But according to an interview with Katalyst’s CEO published yesterday by Ars Technica, the company has made some impressive progress on getting things back under control.

For reasons unknown, the robotic vehicle started tumbling out of control last week. Shortly after that, mission controllers lost contact with Swift. After 24 hours without contact from the ground, the spacecraft automatically performed a sort of “hard reset” in an attempt to regain communications. That got it talking again, but somewhere along the way the craft overheated, which in turn cooked the control circuitry for the reaction wheels, which would usually be used to control its orientation. Not great, not terrible.

As of yesterday’s update, we now know that engineers have figured out a way to gimbal the thrust from the craft’s xenon-fueled electric thrusters — which were originally intended for orbit-raising — to counteract its spinning. It’s slow going as these thrusters don’t have a lot of kick, but it seems to be working. We’ll keep an eye on this one and let you know when we know more.

Thingino Teaches Cheap IP Cameras New Tricks

July 29, 2026 by Tom Nardi 22 Comments

I recently found myself in the market for a few IP cameras to keep an eye on my Prusa 3D printers, and quickly found that the options on the market weren’t exactly ideal. Prusa does offer up an official camera, but the price for a pair of them was a bit more than I wanted to spend on the project. Conversely, there’s no shortage of cheap network-connected cameras available online, but they come with expenses of a different sort, namely proprietary software and cloud services I didn’t want or need.

Somewhere in the deep and dark recesses of this particular rabbit hole, I came across a Reddit post mentioning how a camera running the community-developed Thingino firmware could be plugged into Prusa’s remote printer monitoring scheme. It wasn’t a project I’d heard of previously, and sure enough, a search of the Hackaday back catalog showed we’d never come across it before.

My interest was already piqued, but the discovery that I already owned a supported camera sealed the deal. It was time to explore a new entry in one of my absolute favorite project categories: an open source replacement firmware that turns a cheap consumer device into something more than the sum of its parts.

At a time when so-called “artificial intelligence” seems inescapable, we were encouraged to see news that Amazon will be cracking down on third-party sellers that use AI-generated images for their product listings. They won’t be prevented from using the images, but they will need to clearly indicate that they don’t represent reality and were produced via artificial means. This comes in response to a recently enacted New York law that requires the disclosure of AI in advertisements.

Will this be the end of the cat sleeping bag?

But it’s not quite a clear cut as it might seem on the surface, as the New York law is actually about AI-generated people rather than products. Specifically, it’s designed to make it clear when a “synthetic performer” has been used in place of a human actor. As such, it would appear that the easiest way for Amazon sellers to dodge the new rule is to simply not include any humans in their AI slop images and videos. In other words, they can continue to post fake pictures of products without having to inform the consumer so long as they don’t show a fake person holding it.

Under normal circumstances we’d leave something like this next one for our weekly security column, but the utter lack of security in the Pope’s official “Click To Pray” mobile application revealed by researcher BobDaHacker on Friday is just too good a story to pass up. For one thing, who knew that there was an “official” prayer app? We don’t dabble in theology around these parts, but we’re fairly sure the good book didn’t mention anything about requiring a smartphone to give praise.
