Miniature battery-operated fans are convenient for transportation.
During the summer months, it can be of great benefit to have a mini fan at your disposal to keep you cool, especially on the warmer days. Mini fans are usually battery powered which can be useful for being outdoors in areas that have no electrical outlets or sources of electricity. The fans are easily transportable and convenient because they have no wires and are compact in size. You can build your own battery-powered miniature fan that you can transport to various places during the summer to help you battle the heat.
Instructions
Fan Blades
1. Place a CD on a flat surface with the shiny side of the CD facing upwards. Cut eight lines into the CD to make eight sections. Ensure the cuts do not cut through the clear plastic ring in the center of the CD.
2. Light a candle with a lighter. Place the center of the CD approximately 1 to 2 inches over the candle's flame to warm up the CD. This will make bending the CD sections less difficult.
3. Bend each section or blade to approximately a 30-degree angle. Move the CD away from the flame periodically to avoid melting the CD itself.
4. Insert the cork into the center of the CD. Apply a small amount of glue to the cork and CD to secure the cork to the CD.
5. Insert a needle in the center of the cork. The needle should be approximately the same diameter as the motor's armature.
Building the Fan
6. Place one of the 2-by-4 boards on a flat surface. Glue the second board perpendicular in the center of the first board with wood glue. This will form the stand for the fan.
7. Secure the motor to the front of the upright 2-by-4 with electrical tape.
8. Apply a small amount of glue to the free end of the needle. Insert the needle into the motor's armature to secure the blades to the motor.
9. Cut two electrical wires to 1-foot lengths. Strip approximately half an inch of insulation off the ends of the two wires.
10. Attach one end of the first wire to the positive terminal on the motor. Connect one end of the second wire to the motor's negative terminal.
11. Connect the free end of the first wire to the positive terminal on the battery and secure the connection with a small piece of electrical tape. Join the remaining end of the second wire to the negative terminal on the battery and secure with electrical tape.
