Hackaday Podcast Episode 364: Clocks, Cameras, And Free Will

This week, Hackaday’s Elliot Williams and Kristina Panos met up over assorted beverages to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so.

In the news, there’s quite a bit to talk about. Regarding Hackaday Europe, you can rest assured that the talks will be announced soon. The Green-Powered Challenge is still underway, and we need your entry to truly make it a contest. You have until April 24th to enter, so show us what you can do with power you scrounge up from the environment!

As usual, we published a handful of April Fool’s posts, which you may or may not find amusing. And finally — no fooling — our own Tom Nardi wrote up the Artemis moon launch, and is going to update the post every day until the mission ends.

On What’s That Sound, we can score one for Kristina, which brings her record to approximately three wins and sixty-eight losses. She knew without a doubt that the dialogue was from the Day the Earth Stood Still (1951). Oh, what? There was a remake in 2008? Kristina should get bonus points, then.

After that, it’s on to the hacks, beginning with the basics of making clean enclosures that are decidedly not 3D-printed, a couple of sweet lo-fi cameras, and a nice way to tame the tape when it comes to SMT parts. We also discuss a clock that marks time in a mathematical way, watch an electro-permanent magnet in action, and improving soda by turning it into mead. Finally, we discuss the solar balconies taking Europe by storm, and Copilot’s terrifying terms of service.

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

This Week In Security: The Supply Chain Has Problems

The biggest story of the week is a new massive supply chain breach, which appears to be unrelated to the previous massive supply chain breaches, this time of the Axios HTTP project.

Axios was created as a more developer-friendly Javascript HTTP interface for node.js, giving a promise-based API instead of the basic callback API. (Promise-based programming allows for simpler coding workflows, where a program can wait for a promise to be fulfilled, instead of the developer having to manage the state of every request manually.) Javascript has since provided a modern Fetch API that provides similar functionality, but Axios remains one of the most popular packages on the node.js NPM repository, with 100 million weekly downloads.

The lead developer of Axios believes he was compromised by a collaboration request – a common tactic for phishing specific targets: a project for an IDE like VS Code can include code that executes on the developers system when the project is run. Even outside a traditional IDE, common development tools like configure scripts and makefiles can easily run commands.

Socket.dev breaks down the attack in detail. Once the attackers had credentials to publish to the Axios NPM, they inserted malware as a new dependency to Axios, instead of modifying Axios itself. This likely helped the attack bypass other security checkers. The dependency – plain-crypto-js – is itself simply a copy of a popular encryption utility library, but one which executes additional code during the post-installation process available to all NPM packages.

Sega Meganet: Online Gaming In 1990

It’s easy to think of online console gaming as an invention of the 2000s. Microsoft made waves when Xbox Live dropped in 2002, with Nintendo and Sony scrambling to catch up with their own offerings that were neither as sleek or well-integrated.

However, if you were around a decade earlier, you might have experienced online console gaming much closer to the dawn of the Internet era. As far back as 1990, you could jump online with your Sega Mega Drive. But what did an online console feel like in the dial-up era?

Ask Hackaday: Using CoPilot? Are You Entertained?

There’s a great debate these days about what the current crop of AI chatbots should and shouldn’t do for you. We aren’t wise enough to know the answer, but we were interested in hearing what is, apparently, Microsoft’s take on it. Looking at their terms of service for Copilot, we read in the original bold:

Copilot is for entertainment purposes only. It can make mistakes, and it may not work as intended. Don’t rely on Copilot for important advice. Use Copilot at your own risk.

While that’s good advice, we are pretty sure we’ve seen people use LLMs, including Copilot, for decidedly non-entertaining tasks. But, at least for now, if you are using Copilot for non-entertainment purposes, you are violating the terms of service.

Solar Balconies Take Europe By Storm

Solar power has been around for a long time now. Once upon a time, it was mostly the preserve of research projects and large-scale municipal installations. Eventually, as the technology grew ever cheaper, rooftop solar came along, and cashed-up homeowners rushed to throw panels on their homes to slash their power bills and even make money in some cases.

Those in apartments or rented accommodations had largely been left out of the solar revolution. That was, until the advent of balcony solar. Popular in Germany, but little known in the rest of the world, the concept has brought home power generation to a larger market than ever.

Medieval Alhambra’s Pulser Pump And Other Aquatic Marvels

Recently the Practical Engineering YouTube channel featured a functional recreation of a pump design that is presumed by some to have been used to pump water up to the medieval Alhambra palace and its fortress, located in what is today Spain. This so-called pulser pump design is notable for not featuring any moving parts, but the water pump was just one of many fascinating engineering achievements that made the Alhambra a truly unique place before the ravages of time had their way with it.

Although the engineering works were said to still have been functional in the 18th century, this pumping system and many other elements that existed at the peak of its existence had already vanished by the 19th century for a number of reasons. During this century a Spanish engineering professor, Cáceres, tried to reconstruct the mechanism as best as he could based on the left-over descriptions, but sadly we’ll likely never know for certain that it is what existed there.

Similarly, the speculated time-based fountain in the Court of the Lions and other elements are now forever lost to time, but we have plenty of theories on how all of this worked in a pre-industrial era.

Hackaday Links: March 29, 2026

Whether it’s a new couch or a rare piece of hardware picked up on eBay, we all know what it feels like to eagerly await a delivery truck. But the CERN researchers involved in a delivery earlier this week weren’t transporting anyone’s Amazon Prime packages, they were hauling antimatter.

Moving antimatter, specifically antiprotons, via trucks might seem a bit ridiculous. But ultimately CERN wants to transfer samples between various European laboratories, and that means they need a practical and reliable way of getting the temperamental stuff from point A to B. To demonstrate this capability, the researchers loaded a truck with 92 antiprotons and drove it around for 30 minutes. Of course, you can’t just put antiprotons in a cardboard box, the experiment utilized a cryogenically cooled magnetic containment unit that they hope will eventually be able to keep antimatter from rudely annihilating itself on trips lasting as long as 8 hours.

Speaking of deliveries, anyone building a new computer should be careful when ordering components. Shady companies are looking to capitalize on the currently sky high prices of solid-state drives by counterfeiting popular models, and according to the Japanese site AKIBA PC Hotline, there are some examples in the wild that would fool  all but the most advanced users. They examine a bootleg drive that’s a nearly identical replica of the Samsung 990 PRO —  the unit and its packaging are basically a mirror image of the real deal, the stated capacity appears valid, and it even exhibits similar performance when put through a basic benchmark test.
