If there’s anything more annoying to an amateur radio operator than noise, we’re not sure what it could be. We’re talking about radio frequency noise, of course, the random broadband emissions that threaten to make it almost impossible to work the bands and pick out weak signals. This man-made interference is known as “QRM” in […]
As it turns out, Sega’s long defunct Dreamcast console is still thinking. The company behind the machine cut support long ago due in part to the commercial pressures applied by Sony’s PlayStation 2 console, but that never stopped the most dedicated of Dreamcast fans from seeking out its true potential.

Family Solanum (nightshade) is generally associated with toxins, and for good reasons, as most of the plants in this family are poisonous. This includes some of everyone’s favorite staple vegetables: potatoes, tomatoes and eggplant, with especially potatoes responsible for many poisonings each year. In the case of harvested potatoes, the chemical responsible (steroidal glycoalkaloids, or […]
The moment everyone has been talking about for years has finally arrived, the European Union’s mandating of USB charging on all portable electronic devices is now in force. While it does not extend beyond Europe, it means that there is a de facto abandonment of proprietary chargers in other territories too. It applies to all […]
BEESAT-1 is a 1U cubesat launched in 2009 by the Technical University of Berlin. Like all good satellites, it has redundant computers onboard, so when the first one failed in 2011, it just switched over to the second.

There’s one which has entranced me over the past few years which I’d like to share with you; the Shitty […]
This is Crater75, an almost completely from-scratch row-staggered wireless split board that [United_Parfait_6383] has been working on for a few months. Everything but the keycaps and switches is DIY.

Over the years, dedicated gamers have created incredible recreations of real (and not so real) locations and structures within the confines of Minecraft. Thanks to their efforts, you can explore everything from New York city to Middle Earth and the U.S.S. Enterprise in 1:1: scale. But what if you wanted to recreate your own town, […]
We all take Ethernet and its ubiquitous RJ-45 connector for granted these days. But Ethernet didn’t start with twisted pair cable. [Mark] and [Ben] at The Serial Port YouTube channel are taking a deep dive into the twisted history of Ethernet on twisted pair wiring. The earliest forms of Ethernet used RG-8 style coaxial cable.

A lot of the projects we feature here on Hackaday engender the classic “build versus buy” argument. We’ve always been puzzled by that; if anyone can appreciate the sheer joy of making something rather than buying it, it should be our readers. But there’s something to be said for buying the stuff you can buy […]
