Intro: How to Make a USB Fan

Hello everyone this instructable is fun to make.
I made it in about 2 minuts.
But there is not enough power from the USB port so the fan spins fast but not fast enough.
sorry about that but it produces enough thrust to move a piece of 4mmX4mm paper.
I used some images from the web because i couldn't take the right photos. 

Step 1: Get the Parts and Tools

you will need:
1 brushless fan
1 USB cord
soldering iron
sticky tape
2 paper clips

Step 2: Putting It Together

here you will be putting it together
1-connect the wires from the fan to the USB cord.solder or twist
2-wrap the tape around the connections to stop short circuts.
3-bend the paper clips to form legs and screw them in place.

Step 3: Testing

warning it might blow up your computer if not built propely.

just joking :-)

    5 volt fans are on sell online :)

    Here's my question - A 5 volt fan would draw enough power from a standard USB port. However, will the 5 volt fan be able to draw a similar amount of power from a USB hub? Probably yes, you would think, if the hub were running on AC power. So, would two 5 volt fans draw 5 volts each from a two port USB-powered USB hub?
