Challenge: Can You Beat This Scary Turbine PumpkinCutter Halloween Project ?
This Halloween project is so scary that the inventor (myself) felt shock and awe at it. I was genuinely scared at the running of this machine...and rightly so! So I figured I would spread the scariness to all who see this machine, to set the mood for a DIY Halloween... The machine in question is what I have named the Tesla CD Turbine. The CD Turbine is magnetically-coupled to a Skilsaw blade. (What I teasingly call the PumpkinCutter Attachment). The Tesla CD Turbine uses recycled CD's and neodymium magnets for rotating parts...nothing else. It can rev up to thousands of rpm. It has no bearings or seals and is magnetically coupled to implements. It runs on either compressed air or water pressure. But hey, put on a magnetically-coupled Skilsaw blade, run it at thousands of rpm, and you have a very dangerous PumpkinCutter! (Instructable is ready...if you dare!) Beat that for a wild, scary, hi-tech, cheap and recycled Halloween project!!
