How to make a cheap fan from parts bought at the dollar store. This fan can be made for about $2 (plus tax), unless you can buy a double ended USB wire, then you can make 2 USB fans for $3 (plus tax). That definately beats the $15 or $20 stores tend to charge for these types of devices.
This is my first instructable so I wouldn't mind if people posted their opinion.
NOTE: Pictures will be added at a later date when I make the second fan, the first one (which I am writting this instructable from) was simply a test to see if it would infact work.
Step 1: Preparing the USB Cable
Cut the USB cable to the length you require (long if you need to attach fan to a USB port in the back of your computer). Becareful not to cut the inner wires, use a wire stripper (if you have one) or simply a pair of scissors (be careful not to cut yourself).
Once the protective jacket has been removed, remove some of the shielding such that the 4 wires which make up the USB cable are exposed.
Cut the white and green wires short (to the protective jacket) as they will not be needed for powering the device.
