thingiverse
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.
