If you need a demonstration of just how far technology has come in the last 40 years, just take a look at this teardown of a 1987 laser particle counter. …read more

Hackaday Europe 2024 is on!  We’re all here in Berlin, and the talks are about to begin. If you’re not, you can join us in spirit on our livestream!  And if …read more

Here at Hackaday we’re suckers for old abandoned technologies, the more obscure the better. The history of the telephone has plenty to capture our attention, and it’s from that arena …read more

If you need to make round things, you probably need a lathe. Can you build one as nice as one you can buy? Probably not. But can you build one …read more

What better way to learn to use Git than a gamified interface that visualizes every change? That’s the idea behind Oh My Git! which aims to teach players all about …read more

Workholding is generally not a problem on a big CNC plasma cutter.; gravity does a pretty good job of keeping heavy sheet steel in place on the bed. But what …read more

Sometime last year, [Jon Petter Skagmo] bought a Dell U3421WE monitor. It’s really quite cool, with a KVM switch and picture-by-picture support for two inputs at the same time. The …read more

The prolific [Peter Waldraff] is at back it with another gorgeous micro train layout. This time, there are no plugs and no batteries. And although it’s crank-powered, it can run …read more

Before Elliot Williams jumps on a train for Hackaday Europe, there was just enough time to meet up virtually with Tom Nardi to discuss their favorite hacks and stories from …read more

The central selling point of qubit-based quantum processors is that they can supposedly solve certain types of tasks much faster than a classical computer. This comes however with the major …read more

So first up, we have BatBadBut, a pun based on the vulnerability being “about batch files and bad, but not the worst.” It’s a weird interaction between how Windows uses …read more

While the average Hackaday reader is arguably less likely than most to install a megacorp’s listening device in their home, we know there’s at least some of you out there …read more

Call us crazy, but music was a whole lot more fun when it was on physical media. Or perhaps just easier to use, especially in the car. Whether your particular …read more

Some projects we cover are simple, while some descend into the sort of obsessive, rabbit-hole-digging-into-wonderland madness that hackers everywhere will recognize. That’s precisely where [Excessive Overload] has gone with the …read more

We’re still in the early days of modern EV infrastructure, so minor issues can lead to a full high voltage pack replacement given the lack of high voltage-trained mechanics. [Ed’s …read more

When the only tool you’ve got is a hammer, every problem starts to look like a nail. Similarly, while a 3D printer is a fantastic tool to have, it can …read more

Home automation projects have been popular as long as microcontrollers have been available to the general public. Building computers to handle minutiae so we don’t have to is one of …read more

Using technologies like electron microscopy (EM) it is possible to capture molecular mechanisms in great detail, but not when these mechanisms are currently moving. The field of cryomicroscopy circumvents this …read more

When a fuse is fitted in a power rail, it gives the peace of mind that the circuit is protected. But in the case of some cheap unbranded fuses of …read more

I will confess. I started writing this post about some stupid systemd tricks. However, I wanted to explain a little about systemd first, and that wound up being longer than …read more
