The 24 Hours of Le Mans races is an extremely prestigious endurance motorsport event which attracts the best cars and drivers from around the world. It’s one of the longest-running races too, taking place once a year since 1923 (with a few obvious understandable gaps). But, like most motorsports, it’s financially out of reach for […]
Long ago, in the aftermath of the UNIX wars, three kernels emerged from the rubble: BSD, Linux, and Hurd. BSD, being UNIX, was held back by legal wrangling in the aftermath of the wars, and that allowed Linux to pull ahead to a pole position it still enjoys to this day. BSD has its following, […]
All the cool new 3D printers have tool-changing heads. Instead of multiplexing filament through one hot end, you simply park one hot end and pick up another. Or pick up a different tool, depending on what you need. There are many advantages to a system like that, but one disadvantage: cost. [Ultimate Tool Changer] has […]
It seems like everybody takes their turn doing an ESP32-based weather display, and why not? They’re cheap, they’re easy, and you need to start somewhere. With the Cheap Yellow Display (CYD) and modules like it, you don’t even need to touch hardware! [likeablob] had the CYD, and he’s showing weather on it, but the Cydintosh […]
Cognitive processes are not something that we generally pay much attention to until something goes wrong, but they cover the entire scope of us ingesting sensory information, the processing and recalling thereof, as well as any resulting decisions made based on such internal deliberation. Within that context there has also long been a struggle between […]
Moon missions are hot again for the first bit since the space race. While the previous period had us land on the big lunar rock, the missions of tomorrow have us living on it. The initial problem of landing in one piece has been solved, but there are many more puzzles to solve. One major […]
A crew lives on a station in a hostile environment. Leaving that environment requires oxygen tanks and specialized gear to deal with pressure differentials. A space station? Nah. A base built on the ocean floor. The US Navy was interested in such a base in the 1960s, and bases like this are a staple of […]
After some water intrusion apparently killed one of [electronupdate]’s Amazon Blink Gen 3 cameras he took this opportunity to do a full teardown and analysis of all the major components. Spread across its three PCBs there are no fewer than two wireless ICs and a custom ASIC for all the major processing. There’s also a […]
Of all the remote-control vehicles one can build, a submarine is possibly the hardest: if something goes wrong with almost any other vehicle, it’s easy to recover and repair, but a submarine is a very different affair. This nearly lost [James] of [ProjectAir] his latest project, a 2.7-meter long RC submarine, but it survived to […]
Friends, there will likely come a time in your life when you have trouble sleeping. When this happens, it may behoove you to do some writing, any kind of writing. But consider that a physical journal will force you to turn past pages you’ve already filled, which may leave you deflated if you happen to […]
