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.

Signing UpStep 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.

but can u tell me step by step how you made that fan work without using the ps2....I took my fan out but I'm having a hard time getting it to work if you can msg me back I would appreciate it thanx....
So first off, you need to, useing extreme care, strip the red and black wires on the fan, then set them aside.
Next, snip one end of the usb cord off (i was using an old cord to an mp3 player, so i snipped off the mini end). Strip off like a 2 inch part of the outer layer of the usb, then snip all the wires except for the red and black ones off. As you could imagine, the next step is to strip the red and black wire of the usb.
Finally, you have to try and solder the wires together (red to red, black to black). This is pretty damn tough due to the fan wires being short and thin, so you might need an extra set of hands helping you out. Tape it up when you're all done (taping the wires separately to insulate them) and plug it in to a computer usb port.
If you need more help go ahead and ask, I could even sketch out some diagrams if you need me too no problem.
you can connect more then one fan to one USB port soo there we dont have to use resistors.
but can anyone explain we how must amount of energy is required to operate a FAN that you have used.
and then its equivalent resistance for 1 fan
thanks for the info
Thank You!
CYa! :)
