This week a reader sent me a story about a CVE in Notepad++, and something isn’t quite right. The story is a DLL hijack, a technique where a legitimate program’s Dynamic Link Library (D…

Finding, collecting, and restoring vintage tech is the rewarding pastime of many a Hackaday reader. Working with old-school gear can be tough, though, when documentation or supporting resources are…

Elliot Williams and Al Williams got together to share their favorite hacks of the week with you. If you listen in, you’ll hear exciting news about the upcoming SuperCon and the rare occurrenc…

If you need to create a high vacuum, there are basically two options: turbomolecular pumps and diffusion pumps. Turbomolecular pumps require rotors spinning at many thousands of rotations per minut…

The tides! Such a unique thing, because on Earth, we don’t just have oceans full of liquid water—we also have a big ol’ moon called Moon to pull them around. You might like to keep trac…

When taking pictures of the night sky, any noise picked up by the sensor can obscure the desired result. One major cause of noise in CMOS sensors is heat—even small amounts can degrade the final im…

We have seen many scam USB chargers appear over the years, with a number of them being enthusiastically ripped apart and analyzed by fairly tame electrical engineers. Often these are obvious scams …

Once upon a time, ham radio was all about CW and voice transmissions and little else. These days, the hobby is altogether richer, with a wide range of fancy digital data modes to play with. [KM6LYW…

The MOS Technologies 6581, or SID, is perhaps the integrated circuit whose sound is most sought-after in the chiptune world. Its three voices and mix of waveforms define so much of our collective m…

It’s a well-known conundrum that while most computers these days are digital in nature, almost nothing in nature is. Most things we encounter in the real world, whether it’s temperature…

It was one of those weeks last week at Hackaday’s home office. My mother-in-law handed me her favorite power bank and said “it’s not charging”. She had every expectation that I’ll open it up, desol…

Sometimes it’s nice when you can do everything you need to do with just one single port. In this vein, [Nicola Strappazzon] whipped up a circuit to combine serial and UPDI programming in a ve…

The modern era of virtual reality really kicked off in earnest just over a decade ago, when the Oculus Rift promised 3D worlds beyond your wildest dreams. Since then, nobody’s been able to co…

Industrial robots like robotic arms are basically everywhere, albeit usually out of the public’s eye in factories. This also means that they get replaced and scrapped all the time, making for…

These days, you can buy full graphical LCD or OLED displays for just a few dollars. However, if you’re so inclined, you can actually get your own segmented LCDs made to suit your own projects…

[Tim] noticed recently that a large number of projects recreating discrete logic tend to do so with technology around 70 years old like resistor-transistor logic (RTL) or diode-transistor logic (DT…

Recently [Anthony Francis-Jones] decided to take a closer look at the inhaler that his son got prescribed for some mild breathing issues, specifically to teardown the mechanical counter on it. Comm…

Skateboards were organically developed in the 1940s and 1950s; 30 years would then pass before the ollie was developed, unlocking new realms for skaters dedicated to the artform. The advent of powe…

We typically think of neon signs as big commercial advertisements, hanging inside windows and lofted on tall signposts outside highway-adjacent businesses. [James Akers] has gone the other route wi…

The idea of using the Apple II home computer for digital photography purposes may seem somewhat daft considering that this is not a purpose that they were ever designed for, yet this is the goal th…
