The problem is the materials. They are starting to diminish. Maybe I should go to a car recycling and scrapping center and look for different aluminum materials.

My latest build is again a desk fan. I had a wooden propeller from an R / C plane and a 12 volt electric motor. I spread out all the materials I had on the table and started drawing and testing to match these heterogeneous materials. There were also two small car radio pulleys and a rubber band about 20 cm in diameter. Last month I had changed the motor bearings from the 3 r / c helicopters I have so I used them for the new build.

As I said, my materials are used or useless.
Slowly the design started to take some shape and I thought that this too should make it look like it is swinging with the help of the 3.2 mm steel wire I had. As a base I would use a piece of wood painted in brown to contrast with the color of aluminum.

I made 3 holes in each pulley for a better image, attached them to the bearings and then placed them in a piece of plexiglass. I put the propeller ball bearing on a wiper from the printer head. Along with some aluminum tubes and 2 pieces of an old car dynamo all the materials were connected together. I placed the electric motor inside the housing from an electric petrol pump and at the rear I mounted a car turbine part as a counterweight so that the entire structure would be in balance since it should be hanging in the air.

The prop bracket is adjustable so that I can stretch the hose and the base with the 2 pulleys is adjustable as well. The power cord for the electric motor is hidden inside the pipes and then plugged in to the 2 steel wires. So when I power the wires, then the motor works. I also added a small aluminum hand-made propeller in front of the motor for a better look.

You insure your pieces of art have a fan base I suppose.
