The ARRL used to have a requirement that any antenna advertised in their publications had to have real-world measurements accompanying it, to back up any claims of extravagant performance. I’m told that nowadays they will accept computer simulations instead, but it remains true that knowing what your antenna does rather than just thinking you know […]
Normal people binge-scroll social media. Hackaday writers tend to pore through online tech news and shopping sites incessantly. The problem with the shopping sites is that you wind up buying things, and then you have even more projects you don’t have time to do. That’s how I found the MAKE-roscope, an accessory aimed at kids […]
Image by [dynam1keNL] via reddit But sir! I can’t believe I missed [dynam1keNL]’s initial flat offering from about a year ago, the mikefive, which came about when he and some friends ordered switches directly from Kailh and Kailh were like, do you want to try these even lower-profile PG1316 laptop switches? It’s called the mikefive […]
Saw what you want about the wisdom of keeping a 50-year-old space mission going, but the dozen or so people still tasked with keeping the Voyager mission running are some major studs. That’s our conclusion anyway, after reading about the latest heroics that revived a set of thrusters on Voyager 1 that had been offline […]
For a while now part of my email signature has been a quote from a Hackaday commenter insinuating that an article I wrote was created by a “Dumb AI”. You have my sincerest promise that I am a humble meatbag scribe just like the rest of you, indeed one currently nursing a sore shoulder due […]
Join Hackaday Editors Elliot Williams and Tom Nardi as they take a whirlwind tour of the best and brightest hacks of the last week. This episode starts off with an update about that Soviet Venus lander that’s been buzzing the planet, then moves on to best practices for designing 3D printed parts, giving Chrome OS […]
Spectre lives. We’ve got two separate pieces of research, each finding new processor primitives that allow Spectre-style memory leaks. Before we dive into the details of the new techniques, let’s quickly remind ourselves what Spectre is. Modern CPUs use a variety of clever tricks to execute code faster, and one of the stumbling blocks is […]
Last time we talked about how the original PC has a limit of 640 kB for your programs and 1 MB in total. But of course those restrictions chafed. People demanded more memory, and there were workarounds to provide it. However, the workarounds were made to primarily work with the old 8088 CPU. Expanded memory […]
You often hear that Bill Gates once proclaimed, “640 kB is enough for anyone,” but, apparently, that’s a myth — he never said it. On the other hand, early PCs did have that limit, and, at first, that limit was mostly theoretical. After all, earlier computers often topped out at 64 kB or less, or […]
