Llearn how to make a simple yet amazing fan at home, also known as “Dyson Fan” using a DC motor and waste cardboard (sunboard).
The most fascinating feature about this device is that it doesn’t have any visible propellers and yet gives wonderful and uniform air flow.There definitely are blades. It’ just that they’re hidden in the base.

It looks like it works pretty well. And while it doesn’t look as good as a Dyson fan, it has its own charm, sort of.
