On the heels of our post on retro-Soviet transistor teardowns and die-shots, [nikitas] wrote in to tell us about a huge thread on rare vacuum devices of all varieties: oddball cathode-ray tubes, obscu...

As robot projects go, [creative ideas km]'s isn't going to impress many Hacakday readers. Still, as an art project or something to do with the kids, it might be fun. But the reason it caught our inter...

Most of our beloved tools, such as Slic3r, Cura or KISSlicer, offer scripting interfaces that help a great deal if your existing 3D printing toolchain has yet to learn how to produce decent results…

For all their joking about "reinventing the wheel", the team behind Ourobot made a very cool robot (German, automatic translation here). The team, at the University of Applied Sciences in "Bielefeld, ...

This weekend, Hackaday will be rolling into New York for the Eleventh HOPE. This biyearly conference draws hackers from all around the globe. There’s a ton going on at HOPE: talks, hardware h…

It seems hard to imagine, but in the early part of the 20th century, there weren’t a lot of great options for creating copies of documents. The most common method was to use carbon paper to c…

Finally the workings of the official BB-8 that you’ve seen rolling around at various events have been revealed. Its makers [Matt Denton] and [Josh Lee] participated in an hour-long presentati…

[3DTOPO] does a lot of metal casting (video link, embedded below). That’s obvious by the full and appropriate set of safety gear, a rarity on YouTube. They had all the equipment to do it the …

For their entry into the Citizen Scientist portion of the Hackaday Prize, the folks at Arch Reactor, the St. Louis hackerspace, are building a microscope. Not just any microscope - this one is low-cos...

You'd think that we've posted every possible clock here at Hackaday. It turns out that we haven't. But we have seen enough that we've started to categorize clock builds in our minds. There are the acc...

Watching robots doing sports is pretty impressive from a technical viewpoint, although we secretly smile when we compare these robots’ humble attempts to our own motoric skills. Now, a new ro…

Scripting languages are for large computers, right? “Real” embedded device work is a hellish, never-ending cycle of code, compile, and re-flash. Well, I used to think so too, but with t…

Sure, you’re a hardcore superuser, but that doesn’t mean you don’t enjoy the finer things in life — like shiny squircles and getting every new app first. But, what’s a…
