If you’ve ever seen a gigantic air dancer on the side of the road and thought you might want one of your own, Davide Marin shows how to create a desktop version here. The flailing figure is constructed out of trash bags that are cut and melted into shape, and designed to stand and dance via a centrifugal blower assembly.

An Arduino Nano board is used to control the waving inflatable’s fan, along with a MOSFET to turn it on and off. A servo can optionally be implemented to direct air output back and forth to make things even crazier. 

It looks like a lot of fun, as seen in the videos below!
