U.S.B. Mini Fan

This is my my first instructable so please be nice, also I have already built it so I had to make the pictures on word.  

For this project you will need 
- Any old U.S.B. cord
-An old computer fan
-Wire cutters/strippers
-multimetre
-Computer to try it out on

 

Get out your U.S.B. cord and find the end with the plug that would go into to device. (no the computer)  

Cut off the plug that goes into the device and if there is a tube thing cut that off too.

Strip 2cm off the outer coating.

You might need to dig through some foil and uncover wire but you should find a few multi-colored wires.  Use your multimeter to find the positive and negative wires. 

Tape down the wires that are not needed.

Connect the fan to the cord.

You can build a base out of Popsicle sticks, thick wire or any thing that can support the fan!

Now when you are on instructables and scorching hot you can plug in your mini fan and cool off!
