A Very Nice Steam Engine Powered Carousel Project That Uses The Joule Thief

A Very Nice Steam Engine Powered Carousel Project That Uses The Joule Thief

Jerry built this great little home made steam engine and the carousel that is powered from the steam engine.  He posted a video of it in operation on you tube. He runs the Carousel and a little generator from the steam engine, the generator is putting out ~900mV that is then boosted using a Mad Scientist Hut Joule Thief board that lights some LEDs that are around the Carousel.

Jerry repairs old vacuum tube radios. If you are in need of getting an old vacuum tube radio back in functioning condition just send me an e-mail at madscientist@madscientisthut.com I will be sure to forward your request to Jerry.

Here are some of the still shots of the carousel in development: ( To see a large format picture, click the picture on this page then on the next page click the image there and the next page will open a full size picture)

We had some high permeability toroid cores shipped in. The permeability is so high that it can achieve somewhere between 3-5uH per each winding. This allows for us to make a High Power Joule Thief with just one winding on each side of the transformer.

The new one winding Joule Thief is very stable, starts up at below 600mV, and runs very bright at 1.5VDC leaving spots in your vision if you happen to glance at the LED while it is on. These units are assembled, tested, and can be purchased here.
