Manually make the fan internals

To manually make the fan internals, you will need the following materials:

1. Motor: Choose a small DC motor with a voltage rating suitable for your power supply. The motor will provide the rotational force for the fan.

2. Fan Blades: You can use various materials for the fan blades, such as plastic, cardboard, or metal. Cut out the blades in a shape that will efficiently move air when rotated.

3. Shaft: Find a metal or plastic rod that fits the motor's shaft size. This will serve as the central axis for the fan blades.

4. Mounting Base: Create a sturdy base to hold the motor and fan blades. It can be made of wood, plastic, or any other suitable material.

5. Wiring: Connect wires to the motor terminals for power supply. Use appropriate connectors or solder the wires to the motor terminals.

Now, follow these steps to assemble the fan internals:

1. Attach the motor to the mounting base using screws or adhesive. Ensure that the motor is securely fixed and aligned properly.

2. Connect the shaft to the motor's shaft by inserting it into the motor's central hole. Make sure it fits tightly and is centered.

3. Attach the fan blades to the shaft evenly spaced apart. You can use adhesive or screws to secure them in place. Ensure that the blades are balanced and aligned properly.

4. Connect the wiring to the motor terminals. If using connectors, match the positive and negative terminals correctly. If soldering, ensure a secure connection.

5. Test the fan by connecting the power supply to the motor. Make sure it rotates smoothly and the blades move air effectively.

6. If necessary, make adjustments to the blade angle, balance, or motor speed to optimize the fan's performance.

Remember to exercise caution when working with electrical components and ensure proper safety measures are followed.
