[Niklas Roy] built a windmill-powered music box for his backyard, and it was so awesome all the neighbors wanted to take a picture of it. Someone even liked it so much that he stole [Niklas]’s windmill in the middle of the night. (We kind of don’t blame them, it’s a gorgeously clean build.)
In the past few weeks [Niklas] has been mass-producing 20 windmills for the KIKK Festival 2017 to be held in November in Namur, Belgium. The windmills will operate in a cluster, and all play “Für Elise” when the wind blows. However, each one is driven independently and so the music is asynchronous. Since he was building a bunch anyway, he built a replacement windmill for his backyard, and documented how to do it.
