TheGeekGroup Quarter Shrinking Machine
You may have seen shrunk coins before but you may not have seen the technology that goes behind making them. Thanks to Aud1073cH for sending in the video above that The Geek Group made showing how they make the coins that they sell as a fund raiser item. If you are interested in purchasing other coins such as the Canadian Toonie (pictured below) have a look at this site here. “After many months of designing, engineering, prototype-building and planning, we are finally shrinking quarters with Project Stomper! The quarters are shrunk with impressive power behind them: 6,000 volts and 100,000 amperes. After the process- which happens in less than 1/100th of a second – the quarters are now about the width of a dime, although significantly thicker.”
            
High Voltage Fractal Patterns Burnt into Wood
Not that burning tracks into wood is anything new but this video shows the process and results very nicely. Makes me want to get a few MOTs connected to a large variac and have fun. I think this would be a great seller at a farmers market type setting where people can see the creative art being made in front of their eyes. Melanie Hoff is using a 15,000 power supply and uses nails and large clips to get the voltage to the wood. You can see that water was used to enhance the conductivity of the wood. You can see that when the path was completed a very controlled burn would occur along the path between the cables. Via: Laughing Squid
