[ad_1] The Raspberry Pi finds a use in a huge variety of applications, and in almost any location you could imagine. Sadly those who use those machines might not be in the same place as the machines themselves, and thus there’s the question of providing a remote connection between the two. This may not be […]

[ad_1] Ever heard of a Dutch company called Holborn (literally, born in Holland)? We hadn’t either, but [Bryan Lunduke] showed us these computers from the early 1980s, and we wondered if they might have appeared in some science fiction movies. They definitely look like something from a 1970s movie space station. The company started out […]

[ad_1] As much as we enjoy spinning up our own solutions, there are times when you’ve got to look at what’s on the market and realize you might be out of your league. For example, take Bluetooth game controllers. Sure, you could make your own with a microcontroller, some buttons, and a couple joysticks. But […]

[ad_1] Supercomputers are always an impressive sight to behold, but also completely unobtainable for the ordinary person. But what if that wasn’t the case? [bitluni] shows us how it’s done with his 256-core RISC-V megacluster. While the CH32V family of microcontrollers it’s based on aren’t nearly as powerful as what you’d traditionally find in a […]

[ad_1] Assess your aquarium’s health with an AI-enabled ultrasonic sensor Arduino Team — May 7th, 2024 Below the surface of any body of water, harmful amounts of toxic gases and contaminates can accumulate, which leads to a loss in fish and plant populations if not fixed quickly. But because most water testing, especially in aquariums, […]

[ad_1] Automation has been a part of the Internet since long before the appearance of the World Wide Web and the first web browsers, but it’s become a significantly larger part of total traffic the past decade. A recent report by cyber security services company Imperva pins the level of automated traffic (‘bots’) at roughly […]

[ad_1] Wait a second, read that title again. This isn’t a throwback 3D printing project at all. That’s “RepTrap” as in reptile trap, and it’s a pretty clever way to study our cold-blooded friends in their natural habitat. Now, game cameras — or trail cameras, if you’re less interested in eating what you see — […]

[ad_1] Cerro Chajnantor, site of TAO Although we have a gaggle of space telescopes floating around these days, there is still a lot of value in ground-based telescopes. These generally operate in the visible light spectrum, but infrared ground-based telescopes can also work on Earth, assuming that you put them somewhere high in an area […]

[ad_1] Old computers meant for big jobs often had an external unit to crunch data in specific ways. A computer doing weather prediction, for example, might have an SIMD (single instruction multiple data) vector unit that could multiply a bunch of numbers by a constant in one swoop. These days, there are many computers crunching […]

[ad_1] [Greg] has been working with the Tang Nano 9K FPGA board. He wanted to use the Gowin Analysis Oscilloscope (GAO) to build an internal monitor into the device for probing internal points. The problem is that the documentation is a bit lacking, so he made a video showing how to make it work to […]
