The journalist’s art is now one of the computer keyboard and the internet connection, but there was a time when it involved sleepless nights over a manual typewriter followed by time spent re…

Ever seen a bit of graffiti in a strange location and wondered how the graffiti artist got up there? It might have been a drone rather than an athletic teen. Disney research has just published an i…

We are used to imagining radio telescopes as immense pieces of scientific apparatus, such as the Arecibo Observatory in Puerto Rico, or the Lovell telescope in the UK. It’s a surprise then th…

Asteroids is one of the classic games of the early arcade era. Launched in 1979 by Atari, it relied upon using an XY vector monitor to deliver crisp graphics for its space-based gameplay. One of th…

One of the great things about hacking together projects these days is how many powerful subsystems are readily available to reuse. [Sanjeet] took full advantage of a whole slate of reusable pieces …

The molar mass of carbon monoxide (CO) is 28.0, and the molar mass of air is 28.8, so CO will rise in an ambient atmosphere. It makes sense to detect it farther from the ground, but getting a tall …

We’ve all heard the range of sounds to be made electronically from mostly discrete components, but what [Kelly Heaton] has achieved with her many experiments is a whole other world, the world…

[Hunter Irving] has been busy with the Nintendo LABO’s piano for the Nintendo Switch. In particular he’s been very busy creating his own custom waveform cards, which greatly expands the…

Here’s something of interest of 3D printing enthusiasts. How do you print lightweight 3D objects? [Tom Stanton] does a lot of stuff with 3D printing and RC airplanes, so yeah, he’s prob…

If you don’t have hearing loss, it is easy to forget just how much you depend on your ears. Hearing aids are great if you can afford them, but they aren’t like glasses where they immedi…

It’s been a while since we’ve shown a DIY wire bending machine, and [How To Mechatronics] has come up with an elegant design with easy construction through the use of 3D-printed parts w…

You may think that cathode ray tube (CRT) TVs and monitors have gone the way of the dinosaur, but you’d be wrong. Many still have them for playing video games at home or in arcades, for vinta…

When it comes to logic technologies, we like to think we’ve seen them all here at Hackaday. But our community never ceases to surprise us with its variety and ingenuity, so it should be a sur…

When engineers are designing buildings, bridges, or other large construction projects, a lot of thought is given to the environment. Some of these considerations might seem obvious, like designing …

We’ve been seeing an influx of repurposed 3D printers recently. Thrifty hackers have been leveraging cheap 3D printers as a way to bootstrap their builds, on everything from laser engravers t…

Everyone’s heard of the “black box”. Officially known as the Flight Data Recorder (FDR), it’s a mandatory piece of equipment on commercial aircraft. The FDR is instrumental …

The last challenge of The Hackaday Prize has ended. Over the past few months, we’ve gotten a sneak peek at over a thousand amazing projects, from Open Hardware to Human Computer Interfaces. T…

There was a time, not so long ago, when hype for desktop 3D printing as so high that it seemed you could print anything. Just imagine it, and your handy dandy magical 3D printer could manifest it i…

[Project Malaikat] is a 3D printed hybrid bipedal walker and quadcopter robot, but there’s much more to it than just sticking some props and a flight controller to a biped and calling it a da…

Ham radio operators bouncing signals off the moon have become old hat. But a ham radio transmitter on the Chinese Longjiang-2 satellite is orbiting the moon and has sent back pictures of the Earth …
