There was a time when building your own satellite and having it placed into orbit would have been a wild dream. Now it is extremely possible, but still not trivial. A CubeSat is a very small satellite that can hitch a ride with a bigger satellite or get tossed out of a friendly space station. […]
Imagine if you will that you are enthroned upon the porcelain, minding your own business while doing your business. You’re catching up on Hackaday on your phone – c’mon, admit it – when a whir and a buzz comes from behind you. You sit up in alarm, whereupon your lower back suddenly feels as if […]
Whether it is motivated by a dream of superhuman strength courtesy of a mech suit or of mobility for those with impaired muscle function, the powered exoskeleton exerts a curious fascination among engineers. The idea of a machine-augmented human body achieving great things is thwarted though by the difficulty of the task, actuators and power […]
If I were to ask you what is the oldest man-made orbiting satellite still in use, I’d expect to hear a variety of answers. Space geeks might mention the passive radar calibration spheres, or possibly one of the early weather satellites. But what about the oldest communication satellite still in use? The answer is a […]
[Thomas] does a lot of interesting experiments with 3D printing and lately, he’s been using the free version of Fusion 360 to do topology optimization. He started with a blocky bookshelf bracket and let the software analyze the loads so it can remove pieces that don’t contribute a lot to the bracket’s strength. This uses […]
This has been an interesting week. First off, security researchers at Armis discovered a set of serious vulnerabilities in the vxWorks Real Time Operating System (RTOS). Released under a name that sounds like the title of a western or caper movie, Urgent/11. Not familiar with vxWorks? It’s a toss-up as to whether vxWorks or Linux […]
You’ve got to hand it to marketers – they really know how to make you want something. All it takes is a little parental guilt, a bit of technical magic, and bam, you’re locked into a product you never knew you needed. This prototype flight tracking nightlight for kids is a great example. Currently under […]
When shopping online, there’s plenty of great deals out there on modern graphics hardware. Of course, if you’re like [Dawid] and bought a GTX1050 Ti for $48 from Wish, you probably suspect it’s too good to be true. Of course, you’d be correct. [Dawid] notes from the outset that the packaging the card ships in […]
It always sounded a bit crunchy, but crunchy in a good way. SEGA’s 16-bit console, whether you call it the Genesis or Mega Drive, always had a unique sound thanks to it’s Yamaha YM2612 sound chip. The chip’s ability to reproduce shredding guitars and blasting bass drums was a joy to hear when placed in […]
