Another non-electronic post. It is an interesting design using cams, levers and microswitches. It’s sort 1960s, in a Rube Goldberg’ish way but it works and that is what counts. Well, the mechanism works well but the fan is noisy and doesn’t move much air. Still, impressive mechanical engineering with a touch of electrical engineering.
This post is basically just a video of what is inside the Tamarack Attic fan. Enjoy:
