We love 3D printing here, but we also love clean air, which produces a certain tension. There’s no way around the fact that printing produces various volatile organic compounds (VOCs), and that we don’t want to breathe those any more than necessary. Which VOCs, and how much? Well, [Jere Saikkonen] has created a handy-dandy calculator […]
Everyone loves tiny microcontroller boards, and the ESP32-C3 Super Mini boards are no exception. Unfortunately if you just casually stroll over to your nearest online purveyor of such goods to purchase a bunch of them, you’re likely to be disappointed. The reason for this is, as explained in a video by [Hacker University] that these […]
[Distracted by Design] loves gear from the 1980s, though some of it isn’t as useful as it used to be. He happened across a cheap old FM radio with a great look, but wanted to repurpose it into something more modern. Thus, he set about turning this cheap piece of old electronics into a stylish […]
[It’s Triggy!] had a problem to solve. His grandma was having issues with hand tremors, which made the basic tasks of daily life difficult to perform. He decided to explore whether a high-tech solution could help best the tremors and make life easier. The video covers multiple ideas on how to stabilize a hand suffering […]
What do you look for in a travel keyboard? For me, it has to be split, though this condition most immediately demands a carrying solution of some kind. Wirelessness I can take or leave, so it’s nice to have both options available. And of course, bonus points if it looks so good that people interrupt […]
Can a long-obsolete Linux phone from 2009 be of use in 2025? [Yaky] has a Nokia N900, and is giving it a go. Back in the 2000s, Nokia owned the mobile phone space. They had a smartphone OS even if they didn’t understand app distribution, they had the best cameras, screens, antennas, the lot. They threw […]
To the surprise of almost nobody, the unprecedented build-out of datacenters and the equipping of them with servers for so-called ‘AI’ has led to a massive shortage of certain components. With random access memory (RAM) being so far the most heavily affected and with storage in the form of HDDs and SSDs not far behind, […]
In an excellent example of one of the most overused XKCD images, the libxml2 library has for a little while lost its only maintainer, with [Nick Wellnhofer] making good on his plan to step down by the end of the year. Modern-day infrastructure, as visualized by XKCD. (Credit: Randall Munroe) While this might not sound […]
[Alireza Alavi] wanted to use an e-ink tablet as a Linux monitor. Why? We don’t need to ask. You can see the result of connecting an Onyx BOOX Air 2 to an Arch Linux box in the video below. Like all good projects, this one had a false start. Deskreen sounds good, as it is […]
Recently, [Edward Schmitz] wrote in to let us know about his Hackaday.io project: SigCore UC: An Open-Source Universal I/O Controller With Relays, Analog I/O, and Modbus for the Raspberry Pi. In the video embedded below, [Edward] runs us through some of the features which he explains are a complete industrial control and data collection system. […]
