The principle of operation of the device, and what is required for its manufacture
So what is the secret of this device? How does it work? The invention of this design belongs to the American Jason Dyson, who used the aerodynamic properties of an airplane wing to create know-how. The device has a fan in its design, but it is hidden in the stand, and its task is to take air from the bottom and accelerate it along the ring, creating a low pressure area on one side, which sucks in air, forcing it to rush through ring. Now such rings are used in the most expensive climatic equipment.
In fact, the device is quite primitive, and you can literally repeat it from scrap materials, such as cardboard.
You can use a used one or buy a new one, it literally costs a penny. In addition to it, you will need thick cardboard for the case.

In the side parts, you need to make two holes for the output of the contact for the power supply and the switch.
