[ad_1] If you’re instrumenting your machine tools, or if you’re just curious, you might want to get granular access to the output of a digital micrometer or the like. [Tommy] set his mind to figuring out the communications protocol of the ClockWise Tools dial indicator for this very purpose. And he succeeded! Work began by […]

[ad_1] Play rock-paper-scissors using a time-of-flight sensor and an Arduino UNO R4 Arduino Team — July 17th, 2024 Owing to its simplicity and fast-paced nature, rock-paper-scissors is a great game to play with friends, and when it comes to translating it into a digital format, many creative adaptations can be made. This version by madmcu forgoes the typical three-button […]

[ad_1] This week Jonathan Bennett and Jeff Massie chat with Sylvestre Ledru about the Rust Coreutils! Why would we want to re-implement 50 year old utilities, what’s the benefit of doing them in Rust, and what do the maintainers of the regular coreutils project think about it? Did you know you can watch the live […]

[ad_1] When you think of art, you might think of portraiture, landscapes, or other kinds of paintings. But mathematics can feel artistic at times, too. We’ve all seen gorgeous Mandelbrot fractals, and less gorgeous Julia fractals, but that’s not all that’s out there. As [Prof. Halim Boutayeb] demonstrates, Maxwell’s equations can show us some real […]

[ad_1] Despite the reputation of polymers used with FDM 3D printing like nylon, ABS, and PLA as being generally indestructible, they do come with a whole range of moisture-related issues that can affect both the printing process as well as the final result. While the concept of ‘baking’ such 3D printing filaments prior to printing […]

[ad_1] Ah, generic unbranded IP cameras. Safe, secure? Probably not. [Alex] has been hacking around with one of his very own, and he’s recently busted the thing wide open. Determining that the camera had a software update function built in, [Alex] saw an opening for hijinks. The first issue was that the camera only accepts […]

[ad_1] Compute Unified Device Architecture, or CUDA, is a software platform for doing big parallel calculation tasks on NVIDIA GPUs. It’s been a big part of the push to use GPUs for general purpose computing, and in some ways, competitor AMD has thusly been left out in the cold. However, with more demand for GPU […]

[ad_1] If you’re reading Hackaday, we’re willing to bet that if somebody asked you about a serial terminal, you’d immediately think about a piece of software — a tool you run on the computer to communicate with some hardware gadget over UART. You might even have a favorite one, perhaps minicom or tio. You’d be […]

[ad_1] You might think of the smartwatch era as beginning with Apple, relatively recently. Or, you might think back to those fancy Timex models with the datalink thing going on in the 1990s. Seiko can beat them all, though, with its UC-2000 smartwatch that debuted all the way back in 1984. The UC2200 was the […]

[ad_1] If you think of supercomputers, it is hard not to think of Seymour Cray. He built giant computers at Control Data Corporation and went on to build the famous Cray supercomputers. While those computers aren’t especially amazing today, for their time, they were modern marvels. [Asianometry] has a great history of Cray, starting with […]
