This week, Oligo has announced the AirBorne series of vulnerabilities in the Apple Airdrop protocol and SDK. This is a particularly serious set of issues, and notably affects MacOS desktops and laptops, the iOS and iPadOS mobile devices, and many IoT devices that use the Apple SDK to provide AirPlay support. It’s a group of […]
Picasso and the Z80 microprocessor are not two things we often think about at the same time. One is a renowned artist born in the 19th century, the other, a popular CPU that helped launch the microcomputer movement. And yet, the latter has come to inspire a computer based on the former. Meet the RC2014 […]
[Sean Boyce] has been busy building board games. Specifically, an electronic strategy boardgame that is miraculously also compatible with Settlers of Catan. [Sean’s] game is called Calculus. It’s about mining asteroids and bartering. You’re playing as a corporation attempting to mine the asteroid against up to three others doing the same. Do a good job […]
The self-propelled zip fastener uses a worm gear to propel itself along the teeth. (Credit: YKK) At first glance the very idea of a zipper that unzips and zips up by itself seems somewhat ridiculous. After all, these contraptions are mostly used on pieces of clothing and gear where handling a zipper isn’t really sped […]
When it comes to open source signal analysis software for logic analyzers and many other sensors, Sigrok is pretty much the only game in town. Unfortunately after an issue with the server hosting, the website, wiki, and other documentation is down until a new hosting provider is found and the site migrated. This leaves just […]
Researchers at Aikido run the Aikido Intel system, an LLM security monitor that ingests the feeds from public package repositories, and looks for anything unusual. In this case, the unusual activity was five rapid-fire releases of the xrpl package on NPM. That package is the XRP Ledger SDK from Ripple, used to manage keys and […]
There’s just something about a satisfying “click” that our world of touchscreens misses out on; the only thing that might be better than a good solid “click” when you hit a button is if device could “click” back in confirmation. [Craig Shultz] and his crew of fine researchers at the Interactive Display Lab at the […]
Sometimes in fantasy fiction, you don’t want to explain something that seems inexplicable, so you throw your hands up and say, “A wizard did it.” Sometimes in astronomy, instead of a wizard, the answer is dark matter (DM). If you are interested in astronomy, you’ve probably heard that dark matter solves the problem of the […]
If you’ve ever fumbled through circuit simulation and ended up with a flatline instead of a sine wave, this video from [saisri] might just be the fix. In this walkthrough she demonstrates simulating a Colpitts oscillator using NI Multisim 14.3 – a deceptively simple analog circuit known for generating stable sine waves. Her video not […]
What’s sixty feet (18.29 meters for the rest of the world) across and superconducting? The International Thermonuclear Experimental Reactor (ITER), and probably not much else. The last parts of the central solenoid assembly have finally made their way to France from the United States, making both a milestone in the slow development of the world’s […]
