It’s probably fair to say that anyone reading these words understands conceptually how physically connected devices communicate with each other. In the most basic configuration, one wire esta…

When a hacker owns an oscilloscope, it’s more than a possession. Weary nights are spent staring at the display, frantically twiddling the dials to coax out vital information. Over time, a bon…

When it comes to choice of metals that can be melted in the home foundry, it’s a little like [Henry Ford]’s famous quip: you can melt any metal you want, as long as it’s aluminum.…

[Scott Harden] wrote in to tell us of some success he’s having using the FT232 chip to speak SPI directly from his laptop to a AD98850 digital signal generator. At least that was his destinat…

We like to think that all these new voice-controlled gadgets like our cell phones, Google Home, Amazon Echo, and all that is the pinnacle of new technology. Enabled by the latest deep learning algo…

There was a time when most 3D printers used ABS plastic. It stinks, is probably bad for you, and tends to warp unless printed in a heated enclosure. So most people have gone to something else, most…

The most computationally intense part of an Apollo mission was the moon landing itself, requiring both real-time control and navigation of the Lunar Module (LM) through a sequence of programs known…

The Hackaday Prize is all about empowering you with the tools you need to create the next great hardware device. To that end, we’ve set up seed funding for your projects, we’ve given yo…

As reported by the BBC, the United States is set to impose a 25% tariff on over 800 categories of Chinese goods. The tariffs are due to come into effect in three weeks, on July 6th. Thousands of di…

If you work for a large company, you probably have test equipment that is routinely calibrated. Some companies have their own metrology labs and others send out to an external lab. In a garage lab,…

When you saw the picture for this article, did you think of a peacock’s feather? These fibers are not harvested from birds, and in fact, the colors come from transparent rubber. As with peaco…

A surprising use of 3D printing has been in creating life-like models of human body parts using MRI or CT scans. Surgeons and other medical professionals can use models to plan procedures or assist…

[Charlie Morris] has been busy building a portable ham radio rig and documenting his progress in a series of videos. You can see the first one below. There’s four parts (more if you count thi…

Manual transmissions! Those blessed things that car enthusiasts swear by and everyone else pretends no longer exists. They’re usually shifted by using the gearstick, mounted in the centre con…

Anyone who has ever wound a coil by hand has probably idly wondered “How do they do this with a machine?” at some point in the tedious process. That’s about when your attention wa…

[Peter] is at it again. Not content with being one of the best RC confabulators on YouTube, and certainly not content with the first airplane he built in his basement, [Peter Sripol] is building an…

Somehow, walking robots at our level never really seem to deliver on the promise that should be delivered by all those legs. Articulation using hobby servos is simple enough to achieve, but cumbers…

While 3D printing has been a great thing all by itself, it has also made electromechanical hardware a commodity item. Instead of raiding an old printer for motors and rods of unknown provenance, yo…

“Wait, was that 423 or 424?” When you’re stuck winding a transformer or coil that has more than a few hundred turns, you’re going to want to spend some time on a winding jig…
