[Azpaca] purchased a fun little toy car from Tamiya, only… there was a problem. The little off-roader wasn’t up to scratch—despite its four-wheel-drive, it couldn’t get over rough ground to …read more
Crystal oscillators are incredibly useful components, but they come with one little snag: their oscillation is temperature-dependent. For many applications the relatively small deviation is not a problem, but especially …read more
Layer adhesion is one of the weak points with FDM 3D printing, with annealing often recommended as a post-processing step. An interestingly creative method for this was published in Science Advances …read more
When you’re spitting out G-Code for a 3D print, you can pick all kinds of infill settings. You can choose the pattern, and the percentage… but the vast majority of …read more
When considering our favorite spy movies and kin that involve deep-sea diving, we’d generally expect to see some high-end watch that costs thousands of dollars and is specially engineered to …read more
Redbox was a company with a moderately interesting business model—it let you rent DVDs from automated kiosks. It’s an idea so simple it’s almost surprising it didn’t appear sooner. Only, …read more
A few months ago, Hackaday’s own Al Williams convinced me to buy a couple of untested, returned-to-manufacturer 3D printers. Or rather, he convinced me to buy one, and the incredible …read more
What do you do with a circa 1985 Casio FX-451 calculator with a bad keyboard? Well, if you are [Poking Technology], you transplant the inside of the calculator to a …read more
These days, turn-by-turn GPS navigation isn’t considered special anymore. It’s in every smartphone and most cheap rental cars, and thus everybody expects you to figure out where you’re going. If …read more
The Timex Sinclair 1000 was a sleek and compact machine, and the US counterpart to the more well-known Spectrum ZX-81. Timex may not have come to dominate the computer market, …read more
Although DIY PCB making has made great strides since the early days of chemical etching, there’s one fly in the ointment: vias. These connect individual layers of the board with …read more
Chalk is fun to draw with, and some people even get really good at using it to make art on the sidewalk. If you don’t like tediously developing such skills, …read more
Quadcopters are flying machines. Traditionally, that would mean you’d optimize the design for lightweight and minimum drag, and you’d do everything in a neat and tidy fashion. The thing is, …read more
Was your 3D printer working fine over the summer, and now it’s not? With colder temperatures comes an overall surge in print failure reports — particularly with resin-based printers that …read more
It was Dan and Elliot behind the microphones today for a transatlantic look at the week in hacks. There was a bucket of news about AI, kicked off by Deepseek …read more
Remember the ZEOS Pocket PC? Perhaps you knew it as the Tidalwave PS-1000. Either way, it was a small clamshell computing device that was first released all the way back …read more
DeepSeek has captured the world’s attention this week, with an unexpected release of the more-open AI model from China, for a reported mere $5 million training cost. While there’s lots …read more
If you compare a modern PCB with a typical 1980s PCB, you might notice — like [lcamtuf] did — that newer boards tend to have large areas of copper known …read more
For those times when you could really use a quick 3D model, this metric screw generator will do the trick for screws between M2 and M16 with matching nuts and …read more
