Unix and, by extension, Linux, has a mantra to make everything possible look like a file. Files, of course, look like files. But also devices, network sockets, and even system …read more Continue reading Linux Fu: Fusing Hackaday
One of the nice things about the Unix philosophy that Linux inherited is that the filesystem is very modular. That’s good, too, because a typical system might want a choice …read more Continue reading Linux Fu: User Space File Systems — Now for Windows, Too!
Founders JT Garwood and Jack Miller started Bttn after seeing the challenges medical organizations had during the global pandemic to not only find supplies, but also get fair prices for them. Continue reading Medical supply marketplace startup bttn. sews up additional $5M seed
Fuses are generally there to stop excessive electrical currents from damaging equipment or people’s soft, fleshy bodies when faults occur. However, some people like to blow them just for fun, …read more Continue reading Blowing a 5000 A Fuse Takes Some Doing
Storing data “in the cloud” — even if it is your own server — is all the rage. But many cloud solutions require you to access your files in a clumsy way using a web browser. One day, operating systems will incorporate generic cloud storage just like any other file …read more
There’s a problem with fuses. On the face of it, testing would seem to be a one-shot deal — exceed the rated current and see if it blows. But once you know the answer, the device is useless. If only there were a way to test fuses without damaging them. …read more
The world of DIY circuits for STEM and wearables has a few options for conductors. Wire with Dupont connectors is a standard, as is adhesive copper tape. There’s also conductive nylon/steel thread or ribbon. Which you choose depends on your application, of course, but as a general rule wire is …read more

[Practical Engineering] is ready to explain how power substations get electricity to you in his latest video, which you can see below. One of the things we always notice when talking to people either in our community or outside it is that most people have no idea how most of …read more
Have you heard it said that everything in Linux is a file? That is largely true, and that’s why the ability to manipulate files is crucial to mastering Linux Fu.
One thing that makes a Linux filesystem so versatile is the ability for a file to be many places at once. It boils down to keeping the file in one place but using it in another. This is handy to keep disk access snappy, to modify a running system, or merely to keep things organized in a way that suits your needs.
There are several key features that lend to …read more

Modern LED strips are magical things. The WS2812 has allowed the quick and easy creation of addressable RGB installations, revolutionizing the science of cool glowy things. However, this accessibility means that it’s easy to get in over your head and make some simple mistakes that could end catastrophically. [Thomas] is here to help, outlining a common mistake made when building with LED strips that is really rather dangerous.
The problem is the combination of hardware typically used to run these LED strings. They’re quite bright and draw significant amounts of power, each pixel drawing up to 60 mA at full-white. …read more
