While some byproducts recall an idyllic piece of Americana, others remind us that the past is not always so bright and cheerful. Trinitite, created unintentionally during the development of the first atomic bomb, is arguably one of these byproducts. A Trinitite pendant.

Last time I tried to convince you that, if you haven’t already, you should try running your 3D printer with Klipper. There are several ways to actually make it work. The first thing you need is something to run the Klipper host. Most people use a Raspberry Pi and if you already have one that […]
While it’s the ideal choice for mass production, injection molding is simply no good for prototyping. The molds are expensive and time-consuming make, so unless you’ve got the funding to burn tens of thousands of dollars on producing new ones each time you make a tweak to your design, they’re the kind of thing you […]
If you’ve been reading Hackaday for awhile, you’ll know we’re big fans of OpenSCAD around these parts. There’s a number of reasons it’s a tool we often reach for, but certainly one of the most important ones is its parametric nature. Since you’re already describing the object you want to generate with code and variables, […]
While classroom learning isn’t for everyone, one awesome benefit of the Internet is that you have a variety of college classes available to you, even if they aren’t for credit. You can virtually audit classes from institutions around the world on just about any topic you can think of. Of course, the topic we think […]
Core memory, magnetized memory using tiny magnetic rings suspended on a grid of wires, is now more than five decades obsolete, yet it exerts a fascination for hardware hackers still. Not least [Andy Geppert], who’s made a nibble, four bits of it, complete with interactive LED illumination to show state. Best of all, it’s on […]
So there’s this commercial electronic game out there called Catch Phrase, which, as the game’s own catch phrase explains, is the game that’s played one word at a time. See, a word comes up on the screen, and you have to get the other person or team to guess what it is using gestures and […]
Although Android technically runs on top of Linux, generally most Android devices abstract away the underlying Linux-ness of these machines. In theory this is a good thing; we wouldn’t necessarily want to live in a world where we have to log in to a command-line interface just to make a phone call. But too much […]
Cutting grass with lasers works great in a test setup. (Credit: Allen Pan, YouTube) Wouldn’t it be cool if you could cut the grass with lasers? Everyone knows that lasers are basically magic, and if you strap a diode laser or two to a lawn mower, it should slice through those pesky blades of grass […]
