You may or may not know, but printf is a Turing-complete language, once you exploit all the strange and wonderful format characters in it (especially %n). But who has time to write code as printf modifiers? Now, thanks to [sebsite], you can at least write in a slightly higher level assembly language and compile to […]
Many people who use water cooling in their computer systems like to go full-bore with ‘aquarium’ aesthetic, which includes adding a window to their cooling blocks so that they see the water flowing through the window from behind the case’s window. Traditionally PMMA acrylic is used for these windows, as it’s quite durable and easy […]
We’ll start things off this week with some breaking news from NASA: just days after the space agency announced the Artemis II crew was preparing to blast off towards the Moon as soon as March 6th, a new problem with the Space Launch System rocket has pushed the launch back indefinitely. According to NASA Administrator […]
Meshtastic has been experiencing a bit of a renaissance lately, as the off-grid, long-range radio text messaging protocol gains a ton of new users. It’s been used to create mesh networks in cities, during disasters and protests, in small groups while hiking or camping, and for search and rescue operations. Although it’s connected plenty of […]
You might not have noticed, but we here at Hackaday are pretty big fans of Open Source — software, hardware, you name it. We’ve also spilled our fair share of electronic ink on things people are doing with AI. So naturally when [Jeff Greerling] declares on his blog (and in a video embedded below) that […]
Mega Man is a popular video game character who is perhaps most notable for having a sort of lasery-type blaster for an arm. A real hand cannon, if you will. It’s officially called the Mega Buster, and [Arnov Sharma] recently recreated it for cosplay purposes. Key to any good cosplay build is getting the visuals right, and […]
Recently [ElecrArc240] got his paws on an Intel-branded 3 kW power supply that apparently had been designed as a reference PSU for servers. At 3 kW in such a compact package air cooling would be rather challenging, so it has a big water block sandwiched between the two beefy PCBs. In the full teardown and […]
As far as punctuation goes, the exclamation mark is perhaps the most eye-catching of the bunch. That’s why [Conrad Farnsworth] thought this form would be perfect for his Home Assistant notifier build. The key to this build is the large bi-color printed housing in the shape of an exclamation mark. It makes for an attractive […]
Theoretically a belt drive makes for a great upgrade to a bicycle, as it replaces the heavier, noisy and relatively maintenance-heavy roller chain with a zero-maintenance, whisper-quiet and extremely reliable belt that’s rated at an amazing 20-30,000 km before needing a replacement. Of course, that’s the glossy marketing brochure version of reality, which differed significantly […]
[Hans Rosenberg] has a new video talking about a nasty side effect of using resistors: noise. If you watch the video below, you’ll learn that there are two sources of resistor noise: Johnson noise, which doesn’t depend on the construction of the resistor, and 1/f noise, which does vary depending on the material and construction […]
