For the switch project I came up with multiple ideas. One of them was to get a domino set made out of metal that would work as a switch once they would fall down and connect to the L.E.D. I also thought about using a zipper that would conduct electricity once it is up, but alas, this idea has been used many times before. An other idea of mine was to use collision as a switch, by taking two conductive objects and making them collide, but, unfortunately, I found someone doing that exact same thing in the MAKE Blog (with miniature cars).
My last idea was the one I liked the most: I will create a switch that is powered by wind. It will be in the shape of a “girouette”, and part of it will be constructed with a conductive object, a key for example. If the wind is blowing in the correct direction, the conductive element and the wires will meet to make the L.E.D light up.
I like the idea of using wind to power my switch, and the “girouette” is a great way to harvest that energy. I remember how we used to make these when I was in grade school and how fun it was to run around with them. In that situation, I presume that the L.E.D will blink a lot because of the different directions you take while running. It also is interesting to let the “girouette” on it’s own and to let a natural element (the wind) choose whether the L.E.D will light or not.
