Before anything else, please see the video below in order to get a better idea of the product which I am selling. And please check the feedback on this item--everyone loves it! And by the way, this is a NO RESERVE (NR) auction. Thanks for stopping by and happy bidding.

This is a WindLab Junior Experimental Wind Generator Science Kit. I am an independent inventor doing research in windmills and up until I came across this product, I was forced to build my own little windmills for testing and experiments. Having the WindLab Junior has been a huge benefit to me, which is why I decided to make these available to everyone else. (They are available by others right now, but only if you order directly from Hong Kong--but many people have strong reservations (with good reason) against ordering from out of the country.

What's interesting about the whole windmill science kit market is that there are really only two others available on the market--and they are both well over $150 each. One is made by Edmund Scientific, and the other is available through Pitsco (for $295!)--now I'm sure that they are quality products, I'm just not convinced that they are a couple hundred dollars worth of quality.

I've tried to be as detailed as possible about the kit, which is why I put together the video and included the following information from my website. Though I believe that I have included everything about the kit that I know, you can alway check my website for more information at:

The Generator

The WindLab Junior is designed for children to learn more about this particular form of reneable energy. In order to allow for ease of experimentaion, the WindLab Junior has been designed to operate off of minimal wind speeds which can be generated either naturally or through a normal box fan. A Music Box/ Flash LED/Torch LED Module is included as output loads for the various experiemts that can be run on the device. Just connect the RED and BLACK wire of the module to the RED and BLACK terminals respectively on the DC electrical output connector.

Blade and Vane

The WindLab Junior comes with a set of 3 blades and 1 vane. They are cut from flexible plastics (Poly-Propylene) sheets. The design concept is to let you design your own blades and vanes with easily available plastic or paper card sheets. Scissors and Punch are the standard stationery needed to work with your imagination to create your own blades and vanes. You can modify the number, size and shape of the blades to see what happens to the output of the DC electricity at the output connector. You may also modify the size, shape and color of the vanes to make fun with it.

Modes

The WindLab Junior operates on a small 3-phase AC electrical generator. The AC electricity is rectified to DC electricity and is sent to the output connector in two modes, namely â€œNormalâ€ and â€œDirectâ€.

In â€œNormalâ€ mode, the generated electricity is to be stored in the Gold Capacitor. The â€œ0/1â€ or â€œON / OFFâ€ switch switches the stored electricity to the output connector.

â€œDirectâ€ mode occurs when the 0/1-Switch is slided to the 0-position. In this mode the generated electricity is connected to the output connector which can be used to drive any external device immediately upon roation of the blades. If the 0/1-Switch is slided to the 1-position, the output connector is connected to the gold-colored capacitor.
