If you’ve been following the hubbub about 3I/ATLAS, you’re probably either in the camp that thinks it’s just a comet from ridiculously far away that’s managed to find its way into our solar system,…

The advent of the mobile phone camera has caused a revolution in film making over the last couple of decades, lowering the barrier to entry significantly, and as the cameras have improved, deliveri…

The Raspberry Pi Pico is a very capable board, but it’s still a surprise to see bit-banged 100 MBit/s Fast Ethernet implemented on one. [Steve]’s Pico-100BASE-TX library allows an RP204…

There are some times when a picture, or better yet a video, really is worth a thousand words, and [heinz]’s dual-disk polar 3D printer is one of those projects. Perhaps the best way to describe it …

[Tito] entered a Self-Charging LED Flasher into the Component Abuse Challenge. It’s a simple re-build of a design by the unstoppable [Burkhard Kainka], and while [Tito] doesn’t explain …

From 1945 to 1955, a British aeronautical company called Napier & Son produced not just one but two versions of an intricate hybrid piston engine, which they named the Napier Nomad. The post-Wo…

In the past week, a few forum and Reddit threads have popped up, with people stating that JLCPCB has emailed them with a notice, saying their accounts are set up for terminations after an assessmen…

Usually, a story about hacking a coded message will have some computer element or, at least, a machine like an Enigma. But [Ruth Selman] recently posted a challenge asking if anyone could decrypt a…

[Brian Haidet] published on his AlphaPhoenix channel a laser beam recorded at 2 billion frames per second. Well, sort of. The catch? It’s only a one pixel by one pixel video, but he repeats i…

Carnivorous plants are a fascinating part of the natural world, especially species like the Venus flytrap (Dionaea muscipula) that rely on what is effectively a spring-loaded trap to ensnare unsusp…

Everything is a fuse if you run enough current through it. Or at least [JohnsonFarms.us] seems to think so, which has led him to design 3D-printed fuses made from conductive PLA filament. In theory…

After a quiet week in the news cycle, surveillance concern Flock jumped right back in with both feet, announcing a strategic partnership with Amazon’s Ring to integrate that company’s n…

Indycar Racing 2 was a good game, back in 1995; in some ways, it was the Crysis of the Clinton years, in that most mortals could not run it to its full potential when it was new. Still, that potent…

We don’t know about you, but one of the biggest hassles of having a 3D printer at home or in the ‘shop is the space it takes up. Wouldn’t it be useful if you could fold it down? W…

We aren’t sure if [Looking Glass Universe] didn’t trust the accepted number for Planck’s constant, or just wanted the experience of measuring it herself. Either way, she took some…

Few people know LLMs (Large Language Models) as thoroughly as [Andrej Karpathy], and luckily for us all he expresses that in useful open-source projects. His latest is nanochat, which he bills as a…

Friends, I’ve gotten myself into a pickle and I need some help. A few years back, I decided to get into solar power by building a complete PV system inside a mobile trailer. The rationale for…

Beehives are impressive structures, an example of the epic building feats that are achievable by nature’s smaller creatures. [Full Stack Woodworking] was recently building a new work desk, an…

If you want to print, say, a book, you probably will type it into a word processor. Someone else will take your file and produce pages on a printer. Your words will directly turn on a laser beam or…

Making nylon plastic from raw chemicals used to be a very common demo; depending where and when you grew up, you may well have done it in high school or even earlier. What’s not common is tak…
