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.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
