It is almost summer and soon you will feel the heat. If you don’t have an air-conditioner on your room or office, you probably need this geeky tip to cool your head off.
Wanting to do a simple science project using cheap materials? We will teach you how to make a small fan out of an old CD. First you need the following materials:
- An old CD
- USB Data Cable
- 3 V DC Motor (Can be found on old Walkman)
- Transparent fiber glass
- Electric Tape
- Thick Copper Wire
- Molding Clay
Watch the instructional video below by Navin Khambhala # crazyNK to guide you.
- Using a ruler and marker, divide the CD into 8 eight equal parts from the center.
- Cut the lines using scissors, but remember to stop cutting once you reach the inner circle – the transparent part of the CD.
- Alternately remove four parts of the CD using a cutter leaving four parts behind.
- Slightly bend the remaining parts of the CD to make a propeller; use a lighted candle while doing this.
- Get a transparent fiber glass and cut it on the same size of the center of the CD.
- Then, hammer it with a nail to create a hole that will fit the 3 V DC Motor.
- Glue the motor and fiber glass together before sticking it to the CD propeller
- Once the motor and the CD as joined, cut the end of the USB data cable until you will see for cables colored red and black.
- Connect the red and black wires to the motor.
- In order to make the fan stand and flexible, the think copper wire will serve as a backbone. Attach it on the USB port using a molding clay and on the other end, put another molding clay to the motor.
- Before warping the copper wire to the cable together, glue it first to have a sturdy foundation.
- Bend the cable fan at your own liking and enjoy! 😀
Your improvised USB fan can run on your laptop, computer, power-bank, and even through your smartphone (given that a USB cable receiver is available.
