Joe Groele of Allegany, N.Y., took a flash camera, added a few electronic components and turned it into a coin-tossing gadget. He converted the flash into a strobe, then he ran the electricity through a coil to create a magnetic field. “The changing magnetic field causes an electric current in the coin, called an eddy current, which produces an opposite magnetic field,” says Groele. The nifty current makes the coin repel off the coil and into the air, thus tossing the coin.
The process of turning a camera into a coin flipper came with a few blips. Groele ran a few bumpy tests before a slight nudging of the coin turned into a full toss. Most notably, he discovered that working with high voltages “can be painful.” He also says he should have been “more careful drilling holes in fragile plastic.” Lastly, he found out he didn’t have to destroy nearly as many cameras as he expected. But after numerous trials, he hit pay dirt: a contraption that routinely flips a coin.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
