First cut the planks to the desired size and size, and then you can build a base in sequence.

After the base is completed, connect the solar cell to the motor. Remember to connect the black wire to the black wire and the red wire to the red wire.

After the connection is made, the solar cell is attached to the pre-made seat, and then the fan blade is inserted into the motor.

Then illuminate the solar cell with light, let it absorb the energy, and the fan blade will rotate.
