The ps command is extremely useful when you want to get some quick information on active system processes (hence the name), especially followed by piping it into grep and kin for some filtering. One gotcha is of course that ps doesn’t run in the current shell process, but is forked off into its own process, […]
Last time, we talked about single-PCB-design panels, all the cool aspects of it, including some cost savings and handling convenience. Naturally, you might wonder, and many did – can you put multiple different PCBs on a single panel? The answer is “yes, without a doubt!” The tool we used last time, KiKit, will not be […]
We’ve talked about PXE booting the Raspberry Pi 3B+, and then looked at the Raspberry Pi 4 as a desktop replacement. But there’s more! The Pi 4 sports a very useful new feature, the flashable bootloader. Just recently a beta version of that bootloader was released that supports PXE — booting up over the network […]
Don’t write off your weird ideas — turn them into reality. For years, woodworkers have used pen bodies as a canvas for showing off beautiful wood. But what’s the fun in that? [JPayneWoodworking] made a pen out of Ramen noodles just to see if he could. The process is pretty straightforward, as he explains in […]
Woodworking is messy business, especially the sanding part. But even if you don’t care what happens to your shop floor, you don’t want dead tree particulate matter in your lungs. Wearing a mask or even a respirator is a good start, but a dust collection system is better. Someday, [XYZ Create] might have a shop-wide […]
For humans, life is in the eyes. Same deal with automatons. The more realistic the eyes, the more lifelike (and potentially disturbing) the automaton is. [lkkalebob] knows this. [lkkalebob] is so dedicated to ocular realism in his ultra-real eyeballs that he’s perfected a way to make the minuscule veins from a whisper of cotton thread. […]
The simple plasma ball – it graces science museums and classrooms all around the world. It shares a place with the Van de Graaf generator, with the convenient addition of spectacular plasma rays that grace it spherical surface. High voltage, aesthetically pleasing, mad science tropes – what would make a better DIY project? For some […]
There’s been a lot of Altoids tin hacks over the years, but a vacuum cleaner in a tin is something new. In [Toby Bateson]’s first project on Hackaday, he used simple household items to create a functioning vacuum cleaner to use for sucking crumbs out of your keyboard or paper punch holes off your desk. […]
It may not be a laundry-folding robot, but this robotic launders line build by [Radical Brad Graham] is pretty neat. He has a 75-foot hanging laundry line from his house to a woodshed, and decided to roboticize it using some bits that were lying around. The result is a simple build that adds push-button control […]
