Producing hot water off-grid is a surprisingly energy-intensive activity, and although it looks simple on its surface it can get quite complicated especially when used in large scale for something like providing hot water for an entire home. When using combustion to heat the water there needs to be proper venting as well as control […]
You can get all kinds of fancy lenses for modern cameras, with all sorts of mechanical and electronic wizardly to make them shoot better images. But what if you paired a vintage lens with a modern camera? It would take some work, as [Mathieu] found out, but you’d also get some interesting results. The optic […]
Continuing his quest to put DOOM on literally everything that has a capable enough processor and a screen, [Aaron Christophel]’s most recent target is a Slate 7 Pro travel router. With a generous 2.8″ touch screen and a lot of onboard processing power to handle all the advertised networking and routing features via its WAN and […]
This week, Hackaday’s Elliot Williams and Kristina Panos met up over the international tubes to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so. Regarding Hackaday Europe, we announced the last round of speakers and opened up the workshop ticket […]
Phones can be distracting objects if you’re not an enlightened master of the mental arts. Even just reading an email or glancing at your calendar can get you caught up checking other apps and notifications and waste your time. [Paul Lagier] built a device to eliminate this problem by showing him critical information right on […]
Making headlines everywhere is the CopyFail Linux kernel vulnerability, which allows local privilege escalation (LPE) from any user to root privileges on most kernels and distributions. Local privileges escalations are never good, but typically are not “Internet-melters”: they are significantly less dangerous than remote vulnerabilities, but are often combined with a remote vulnerability to gain complete access to a […]
Since Sony’s PlayStation 5 console is quite literally an AMD-based gaming PC with a custom mainboard, the only thing that really keeps anyone from just installing another operating system on it is the hypervisor-based firmware. Since in older firmware for the original ‘phat’ PlayStation 5 there exists a hypervisor exploit, this logically means that you […]
Here at Hackaday we cover the world of retrocomputing, which means that we see all manner of older computers in our everyday work. We might even claim that we’ve seen them all, were it not that every now and then something comes along which surprises us. [Tynemouth Software] has done just that, with an unexpected […]
Before Linux, there was Unix. It was great, but it was and has been plagued by problems with licensing and proprietary competition. [Vintage Appartus] recalls, for example, the AT&T Unix PC from the 1980s. It was awesome, but you’ve probably never heard of it. For 1985, it was a nice setup. You got a 10 […]
Normally, when you design an electronic gadget, you worry about how hot it will get. Automotive-grade components, for example, often have higher allowable temperatures than commercial parts. However, extremely cold environments, such as deep space or the interiors of quantum computers, are also challenging. Researchers at King Abdullah University of Science and Technology believe gallium […]
