[Ken] recently obtained an attitude indicator—sometimes called an artificial horizon—from an F-4 fighter jet. Unlike some indicators, the F-4’s can rotate to show pitch, roll, and yaw, so it moves …read more Continue reading Inside the F-4 Attitude Indicator
The truth is, our desktop computers today would have been classed as supercomputers only a few decades ago. There was a time when people who needed real desktop power looked …read more Continue reading The Last Sun Sparc Workstation
[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? …read more Continue reading Spectroscopy on the Cheap
[Ben] may be 15 years old, but he’s got the knack for 3D printing and artistic mechanical design. When you see his 3D-printed mechanical jellyfish lamp, we think you’ll agree. …read more Continue reading 3D Printed Jellyfish Lights Up
It is hard to imagine that a handful of decades ago, TV wasn’t a thing. We’ve talked a few times about the birth of television. After an admittedly slow slow …read more Continue reading Retro Gadgets: Things Your TV No Longer Needs
