[Mark] starts a post from a bit ago with: “… maybe you have also heard that SystemVerilog is simply an extension of Verilog, focused on testing and verification.” This is both true and false, depending on how you look at it. [Mark] then explains what the differences are. It’s a good read if you are […]
[Extreme Kits] asks the question: “What the hell is a luminiferous theremin?” We have to admit, we know what a thermin is, but that’s as far as we got. You’ve surely seen and heard a theremin, the musical instrument developed by Leon Theremin that makes swoopy music often associated with science fiction movies. The luminiferous […]
One can only imagine the wonders held within the crypto labs of organizations like the CIA or NSA. Therein must be machines of such sophistication that no electronic device could resist their attempts to defeat whatever security is baked into their silicon. Machines such as these no doubt bear price tags that only a no-questions-asked […]
Anyone who has done an electronic engineering qualification will at some point have had to get to grips with transmission lines, and then if they are really lucky, waveguides. Perhaps there should be one of those immutable Laws stating that for each step in learning about these essential parts, the level of the maths you […]
It could happen to anyone of us: suddenly you got this inkling of an idea for a product that you think might just be pretty useful or even cool. Some of us then go on to develop a prototype and manage to get enough seed funding to begin the long and arduous journey to turn […]
Who among us hasn’t at some point thought of building a little vehicle, and better still, a little off-road vehicle for a few high-octane rough-terrain adventures. [Made in Poland] has, and there he is in a new video with a little off-road buggy. The video which we’ve paced below the break is quite long, and […]
Hackaday Editors Elliot Williams and Al Williams reflect on the fact that, as humans, we have–at most–two eyes and no warp drives. While hacking might not be the world’s most dangerous hobby, you do get to work with dangerous voltages, temperatures, and frickin’ lasers. Light features prominently, as the guys talk about LED data interfaces, […]
Few consumer-grade PCs are what you’d categorize as built to last. Most office-grade machines are as likely as not to give up the ghost after ingesting a few too many dust bunnies, and the average laptop can barely handle a few drops of latte and some muffin crumbs before croaking. Sticking a machine like that […]
You may have heard some scary news about RISC-V CPUs. There’s good news, and bad news, and the whole thing is a bit of a cautionary tale. GhostWrite is a devastating vulnerability in a pair of T-Head XuanTie RISC-V CPUs. There are also unexploitable crashes in another T-Head CPU and the QEMU soft core implementation. […]
Researchers demonstrate sustainable 3D printing by using poly(N-isopropylacrylamide) solutions (PNIPAM), which speedily and reliably turn solid by undergoing a rapid phase change when in a salt solution. This property has been used to 3D print objects by using a syringe tip as if it were a nozzle in a filament-based printer. As long as the […]
