In the process of making a wind generator

To make generator blades, you need to cut 2 aluminum cans lengthwise. On the halves at the edges, you need to clean the metal for soldering. These places need to be sealed, and spokes from a bicycle wheel must be soldered to them.

Banks with spokes are glued to washers. As a result, light blades are obtained. A tube is placed between the washers, then everything is placed on the pin. Next, we tightly tighten the structure with nuts on both sides.

We take a piece of plywood and drill it under the bearing. The bearing is pressed into the hole and is additionally fixed with glue. We fasten the mounting corner on the side.

A small 12 V electric motor fixed to the corner with clamps. Then the axis with blades clamped with nuts on the bearing.

A plastic gear screwed onto the axis and fixed with nuts. It should come into contact with the gear on the motor shaft. Thus, when turning the blades, the engine must also rotate.

A step-up converter soldered to the wires from the engine. On its output we solder a USB connector on long wires. Then we close all of these covers to protect from precipitation. USB output from the case.

As a result, we get a small wind generator that can to charge the phone.

If the wind is gusty in your area, then it is better to connect a 10 V 2000 μF capacitor parallel to the engine. With him, the charge will be more stable.
