A camera obscura is a very simple device. Consisting of a dark chamber, with only a pinhole to let light in, it focuses an image on its inside surface. If you want to take a permanent copy, it&#821…

The field of soft robotics sure seems a lot less mature than your standard servo motor and metal framed robot arms. Maybe that’s because building a robot to flex is harder, and maybe it&#8217…

[randomprojectlab] is building a synthesizer around the pentatonic scale for the Hackaday Prize. It’s the Pentasynth, and it’s basically just a keyboard with five notes per scale. There…

The command line. You either love it or hate it, but if you do anything with a Unix-like system you are going to have to use it eventually. You might find marker — a system billed as a &#8220…

You’ve no doubt heard about the “hardware implants” which were supposedly found on some server motherboards, which has led to all sorts of hand-wringing online. There’s no e…

When you think about singer-songwriters, the name Bob Dylan might come to your mind. You might think about Jeff Buckley, you might think about Hank Williams, Springsteen, David Bowie, or Prince. Yo…

If you’ve ever been to Amsterdam, you know there are plenty of canals and, therefore, plenty of bridges. Next year, a unique pedestrian bridge in the old city center will go into service. The…

Digital video is cool and all, but it can’t compete with analog in terms of smooth, creamy glitches and distortion. [gieskes] has developed an analog audio-visual synthesizer that is a great …

The first photograph was taken sometime in the early 1800s, and through almost two centuries of development we’ve advanced through black-and-white, the video camera, and even high-speed camer…

Sometimes you need to hack on the go. [Supertechguy] has put together an interesting system for hacking on the hoof called the Pineapple Pi. This combines a Raspberry Pi 3 with a seven-inch touchsc…

“Everything is a spring”. You’ve probably heard that expression before. How deep do you think your appreciation of that particular turn of phrase really is? You know who truly, viscerally groks thi…

If you’ve never heard a hurdy-gurdy before, you’re in for a treat. Not many people have, since they’re instruments which are uncommon outside of some eastern European communities.…

Hackaday Superconference is just a week away (precious few tickets remain), a celebration of all things Hackaday, which naturally includes creative projects making the most of their hardware. Every…

Imagine you’re a general, camped outside a fortified city with your army. Your army isn’t strong enough to take the city without help. But you do have help: camped on other hills outsid…

The GePS is a musical project that shows how important integration work is when it comes to gesture controls. Creators [Cedric Spindler] and [Frederic Robinson] demonstrate how the output of a hand…

Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners t…

We’ve always had a fascination with things that fly. Sure, drones are the latest incarnation of that, but there have been RC planes, kites, and all sorts of flying toys and gizmos even before…

The inside of classic radios holds wonders that the sterile chips and SMD components of today’s circuits can’t hold a candle to. Chunky resistors and capacitors, vacuum tubes with catho…

We’ve probably all got at least one old cell phone lurking somewhere around our bench. In most cases they’ll still work, but their  batteries may be exhausted and their OS could be an a…

A pushcar is a great toy for a young child. They’re great excercise, and kids love anything on wheels. However, the bigger kids might want something with a little more grunt. [Master Milo] ha…
