As the sun goes down on a glorious spring evening on the western edge of Europe, Elliot Williams is joined by Jenny List for a look at the week in all things Hackaday. First up: Hackaday Europe tickets are on sale! Bad luck folks, the early bird tickets disappeared in an instant, but regular ones […]
Sometimes you wanna test a piece of USB hardware, but you don’t just want to plug it into a random old phone charger. [KS-Elektronikdesign] has whipped up a useful tool for just that case, allowing one to easily power USB hardware from a common bench supply. It would have been simple enough to whip up […]
The ides of security March are upon us — Qualys reports the discovery by their threat research unit of vulnerabilities in the Linux AppArmor system used by SUSE, Debian, Ubuntu, and Kubernetes as an additional security mechanism and application firewall. AppArmor was added to Linux in 2010, and the vulnerabilities Qualys discovered have been present since […]
It’s no secret that Google really doesn’t like it that people are installing Android applications from any other source than the Play Store. Last year they proposed locking everyone into their official software repository by requiring all apps to be signed by verified developers, an identity which would be checked against a Google-maintained list. After […]
We’re not exactly worried about Armageddon here at Hackaday, but should we end up facing the end of the world as we know it, having something to pass the time would be nice. That’s why we were intrigued by [Janus Cycle]’s latest video where he both plays and powers a Game Boy by candlelight. You’ve […]
The Raspberry Pi line of single-board computers can be hooked up with a wide range of compatible cameras. There are a number of first party options, but you don’t have to stick with those—there are other sensors out there with interesting capabilities, too. [Collimated Beard] has been exploring the use of the IMX585 camera sensor, […]
The test setup for the Battle Born LFP cycling. (Credit: Will Prowse, YouTube) There has been quite a bit of news recently about the Battle Born LiFePO4 (LFP) batteries and how they are dying in droves if not outright melting their plastic enclosures. Although the subsequent autopsies show molten plastic spacers on the bus bars […]
Sometimes the right tool for the right job appears almost out of nowhere. That was certainly the case for [Jonathan] who came across an unusual but well-designed robot at a secondhand shop. The robot needed a bit of work to get back into a usable condition, but after that it was ready for use. For […]
Sometimes you really need to know what the weather is doing, but you don’t want to look at your phone. For times like those, this neat weather display from [Jordan] might come in handy with its throwback retro vibe. The build is based around the ESP32-2432S028—also known as the CYD, or Cheap Yellow Display, for the […]
You have a tiny twenty-year-old hard drive with a weird interface. How do you read it? If you’re [Will Whang], by reverse engineering, and building an interface board. In many of our portable, mobile, and desktop computers, we’re used to solid-state storage. It’s fast and low power, and current supply-chain price hikes notwithstanding, affordable in […]
