The latest Gadget Freak from design news is up! –
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. â€œThe changing magnetic field causes an electric current in the coin, called an eddy current, which produces an opposite magnetic field,â€ 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 â€œcan be painful.â€ He also says he should have been â€œmore careful drilling holes in fragile plastic.â€ Lastly, he found out he didnâ€™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.
