I remember Doc giving that lesson in "Back to the Future" demonstrating "Voltage vs. Amperage" where his hair was standing on end. So I guess that really means that when you see those bold WARNING HIGH VOLTAGE signs on Cellular towers and other fenced-off electrical sub-stations, you can really just say, "Oh Voltage, Schmoltage -- I ain't scared" !!
The loudest SNAP I ever heard came about while I was cleaning out the sump pump during a thunderstorm, when I was young and foolish. As I approached the pipe with a screwdriver I saw a large arc jump across the pipe and into my hand with a loud SNAP! My arm flew across the room and the rest of my body chased after my arm, having grown quite found of it after all those years. It wasn't until then that the thunder sounded. The thunder was louder than the SNAP, but the SNAP had visual and sensory cues that the thunder lacked.
After that any problems with the pump were resolved after the rain stopped.
I find it interesting that the sound of the stun gun's pop can reveal the strength of its stun power. That actually fits how the human brain rates danger. The louder the sound, the more our nervous system reacts.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
