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 […]
Once upon a time, machine learning was an arcane field, the preserve of a precious few researchers holed up in grand academic institutions. Progress was slow, and hard won. Today, however, just about anyone with a computer can dive into these topics and develop their own machine learning systems. Shawn Hymel has been doing just […]
Once the nerve center of Windows operating systems, the Control Panel and its multitude of applets has its roots in the earliest versions of Windows. From here users could use these configuration applets to control and adjust just about anything in a friendly graphical environment. Despite the lack of any significant criticism from users and […]
With as cheap and versatile as RTL-SDR devices are, it’s a good idea to have a couple of them on hand for some rainy day hacking. In fact, depending on what signals you’re trying to sniff out of the air, you may need multiple interfaces anyway. Once you’ve amassed this arsenal of software defined radios, […]
Have you ever looked out the window at traffic and seen a giant crane driving alone the road? Have you ever wanted a little 3D printed version you could drive for yourself without the risk of demolishing your neighbors house? Well, [ProfessorBoots] has just the build for you. The build, inspired by the Liebherr LTM […]
