While plastics are very useful on their own, they can be much stronger when reinforced and mixed with a range of fibers. Not surprisingly, this includes the thermoplastic polymers which are commonly used with FDM 3D printing, such as polylactic acid (PLA) and polyamide (PA, also known as nylon). Although the most well-known fibers used […]
There was a time when building a telescope was a rite of passage for budding astronomers, much as building a radio was the coming age for electronics folks. These days, many things are cheaper to buy than build, even though we do enjoy building anything we can. Orion was a big name in telescopes for […]
The Bluetooth SIG recently released the core specification for version 6.0 of Bluetooth. Compared to 5.x, it contains a number of changes and some new features, the most interesting probably being Channel Sounding. This builds upon existing features found in Bluetooth 5.x to determine the angle to, and direction of another device using Angle of […]
[Thomas Roche] of NinjaLab is out with EUCLEAK, (pdf) a physical attack against Infineon security microcontrollers, and the security tokens that contain them. The name is a portmanteau of Euclidean and leak. And no surprise, it’s a data leak in some implementations of the Extended Euclidean Algorithm (EEA), a component of an Elliptical Curve Digital […]
As we slowly wean ourselves away from our centuries-long love affair with fossil fuels in an attempt to reduce CO2 emissions and combat global warming, there has been a rapid expansion across a broad range of clean energy technologies. Whether it’s a set of solar panels on your roof, a wind farm stretching across the […]
We finally have some answers about the Windows IPv6 vulnerability — and a Proof of Concept! The patch was a single change in the Windows TCP/IP driver’s Ipv6pProcessOptions(), now calling IppSendError() instead of IppSendErrorList(). That’s not very helpful on its own, which is why [Marcus Hutchins]’s analysis is so helpful here. And it’s not an […]
The Macintosh Plus is not exactly known as particularly relevant in the worlds of chiptune or electronic music more broadly. That’s not to say it can’t do anything that sounds cool, however. As [Action Retro] demonstrates, it’s got some really impressive tricks up its sleeve if you know what you’re doing. The video centers around “Music Mouse”, […]
The history of consumer technology is littered with things that came and went. For whatever reason, consumers never really adopted the tech, and it eventually dies. Some of those concepts seem to persistently hang on, however, such as augmented reality (AR). Most recently, Apple launched its Vision Pro ‘mixed reality’ headset at an absolutely astounding […]
There have been some hilarious issues on mobile devices over the years. The HTC Dream had a hidden shell that was discovered when a phone rebooted after sending a text containing just the word “reboot”. iOS has gotten in on the fun from time to time, and this time it’s ""::. Type the double quotes, […]
For decades, the magnetic stripe has been ubiquitous on everything from credit cards to tickets to ID badges. But the BBC reports — unsurprisingly — that the mag stripe’s days are numbered. Between smartphones, QR codes, and RFID, there’s just less demand for the venerable technology. IBM invented the stripe back in the early 1960s. […]
