If you wanna build something high tech, truly scary, cheap, and relatively easy for Halloween, this Steampunk Tesla CD Turbine is it! It uses recycled CD's, Neodymium magnets and a Magnetic Coupling to power tools and implements.

From experience, I can tell you that it's scary enough to be running a high-speed turbine made from recycled CD's, supermagnets and glue
. But running it with a magnetically-coupledSkilsaw blade
, now that's TRULY scary! I would not advise anyone to try this. I only did it to prove a point or two, and they haven't quite made this alien technology safe yet.
This Tesla CD Turbine incorporates many subtle and amazing feaures, such as shaftless, bearingless, magnet-separated CD discs driving magnetically-coupled attachments to high speed.(huh?) More on that later.
The CD Turbine works on either compressed air
or water pressure
. It's cheap and easy to put together, lots of fun and makes cool sounds to boot.Pumpkin Cuttin' Ceremony with the CD Turbine.
However, the PumpkinCutter Skilsaw Blade Attachment has a big element of danger ...for both people and pumpkins! Don't use it!!...I only use the Saw to draw attention to the wonderful attributes and power of this little CD Turbine device, and things got a little out of hand. I promise to never, hardly ever, do it again. (There was an unrehearsed Pumpkin Cuttin' Ceremony
on Halloween, of course...hehe)
I have discovered that this is not a project to take lightly. (With humour, but not lightly.) Under water pressure the Tesla CD Turbine spins a couple of thousand rpm, but under air pressure it is a high-speed dangerous device
that must be treated with utmost respect.
Lets remember, folks, this thing is just a CD case, CD's, and magnets. And glue. Lots of glue. (...and keep telling yourself that when you see the magnetically-coupled PumpkinCutter Skilsaw Attachment smoothly wailing away at way-too-high rpm!!)
This device is built for working demonstration purposes; to prove ideas, not for longevity and everyday use. Hence the danger factor. (i.e. yes, things could self-destruct at any time...hehe)
I can really only recommend building one of these with the PumpkinCutter Attachment if you are a truly dedicated experimenter, and promise to wear your suit-of-armour and carry a shield, and cower behide a far-off wall.
We can, however, make a "point" to have some real fun with something a little less on the leading "edge", so to speak. So I suggest to perhaps substitute a Nerf disc for the sawblade! or use a Frisbee! maybe make a CD Turbine-powered Frisbee Impeller?Hi-Speed Testing of the Tesla CD Turbine
