decorative wind velocity indicator

Short Info:
This is the first prototype of a wind velocity indicator. So far it only is of decorative use. In further projects and other configurations, it will be modified in such a way, that it can produce small amounts of electricity.

Requirements:

- some wood screws to fasten the spoon like blades
- glue to put the "Rotorhalter" together with the "Lagerhalter"
- 1x ball bearing (eq. from old inline skaters, Skateboards or so)
- 1x piece of tubing with a fitting inner diameter to put the stand on.
