The Samsung phone debacle. From corporate level, this has been a disaster. Samsung has lost significant portions of it’s market value and smart phone market share. Yet no one would normally assume that a battery would be the issue.
Karl Denninger posted about fake ball bearings recently. The thing is that while he writing in very hyperbolic language, he’s not exaggerating very much.
ThunderF00t has posted some videos about the “Waterseer,” a device that purports to provide drinking water in arid regions. Actually it’s just more of the typical “Green Tech” Hokum where the goal is to separate fools from their money and waste time and energy on fundamentally flawed ideas.
George Westinghouse was one of the most important people in the US. His birthday passed recently without much notice. Most people don’t even know who he is anymore. Which is a true shame because his achievements still affect us every day. It’s well known that Westinghouse developed the air brake for railroads and had that been his only achievement he would still be one of the greatest engineers of all time. But his work and the work of his companies went far beyond just the airbrake.
For long time, one of the best catalogs for inspiration to me was the catalog from Small Parts Inc. This was a great small catalog of the kind of stuff that you might need for making. The catalog had small bearings, gears, heat shrink tube, wire and small tubing, along with a ton of the little things that you might need for a project.
When the space program was started back in the beginning of the 1960’s how to guide the spacecraft in space was a complete unknown. The problem of calculating burns and orbital insertions was a nontrivial one. At the time all flight control had been analog and in 1960, the computers filled up buildings. When the call came to go to the moon, one thing was clear though. A computer small enough to fit on the spacecraft was going to be essential. That computer would be the Apollo Guidance Computer(AGC).
When people first started to fly, an important question emerged. The question was “which way was up?” That seems like and easy question to answer, but when you are flying around in an airplane in a fog, it becomes more complicated. Here’s what aircraft in the early days of flight looked like.
