When you think of the Unix and C revolution that grew out of Bell Labs, there are a few famous names. Dennis Ritchie, Ken Thompson, and Brian Kernighan come to mind. After all, the K in both K&R C and in AWK stand for Kernighan. While Kernighan is no stranger to book authorship — he’s […]
When an earthquake strikes, it’s usually hard to miss. At least that’s the case with the big ones; the dozens or hundreds of little quakes that go largely unnoticed every day are interesting too, and make sense to track. That’s usually left to the professionals, with racks of sensitive equipment and a far-flung network of […]
Most of the time if you were to want to develop for an FPGA, you might turn to Verilog or VHDL. Both of these are quite capable, but they are also firmly rooted in languages that are old-fashioned by today’s standards. There have been quite a few attempts to treat those languages as an output […]
About a year back, [BogdanTheGeek] found himself in need of a new case for this TS100 soldering iron. Unfortunately, while the product is often billed as being open source friendly (at least in the firmware sense), he was surprised to discover that he couldn’t find the detailed dimensions required to 3D print his own replacement […]
There’s long been much handwringing around Halloween around the prospect of pins, needles and razor blades being hidden in candy and passed out to children. On the very rare occasion this does happen, the outcome is normally little more than some superficial cuts. However, for 2019, [MG] has developed an altogether different surreptitious payload to […]
[Dan Royer] is taking some inspiration from Prusa’s business and is trying to build the same sort of enterprise around open source 3D printable robot arms. His 6 axis robot arm is certainly a strong first step on that road. As many people have learned, DIY robot arms are pretty difficult. [Dan]’s arm has the […]
It’s often said that engineers aren’t born, they’re made. Or more accurately, taught, tested, and accredited by universities. If you’re in high school, you’re probably starting to think about potential career paths and may be considering an engineering degree. A lot of work goes into a good college application, and it might seem like the […]
Join us on Wednesday, October 30 at noon Pacific for the SatNOGS Update Hack Chat with Pierros Papadeas and the SatNOGS team! Ever since the early days of the Space Race, people have been fascinated with satellites. And rightly so; the artificial moons we’ve sent into orbit are engineering marvels, built to do a difficult […]
The earliest piston engines typically had only one cylinder, and at best, produced horsepower measured in single digits. But once you have a working engine, it’s a relatively short step to adding cylinders and increasing the power output. [Emiel] made a similar upgrade to one of his engines recently, upgrading it from one cylinder to […]
Your job might be tough, but spare a thought for any of the engineers involved in the Mars InSight lander mission when they learned that one of the flagship instruments aboard the lander, indeed the very instrument for which the entire mission was named, appeared to be a dud. That’s a bad day at work […]
