There are often days when the weather is hot and the power is out. Thankfully, with a few pieces of wire and a couple of components you might already have lying around, you can create a neat little air conditioner that can keep you much cooler.

Materials needed:
> 4 plastic boxes
> Some wire
> Some tape
> A computer fan (it has both a fan and a motor in it) OR electric motor + a fan/turbine connected (make sure the motor goes not above 6 volts). For this project, I didn't have a computer fan, although that would have made things much simpler. I had an RF 310T 11400 motor available here and a small turbine sort of thing
> An old USB cable (any sort of USB cable; you'll be stripping the wire and will only keep the male end)
> An icepack/small container which you will freeze water in
> A laptop/USB compatible power brick

Tools needed:
> Some scissors/ a Swiss Army Knife

Step 1: Make holes in the first box

Take your first plastic box and make a number of holes on all four sides. This will cause warm air to enter the box (and because of the fan which we will place on top later, it will be pulled up). After you're done with the holes, cut a rectangle on its bottom side as shown in the pictures. 

Using a motor or anything higher that 5v won't bother the usb drive. It just won't get the power it wants so it won't perform to its fullest. It will have absolutely no adverse or dangerous affects.
Very helpful. Thank you.
any ice packs or frozen water bottles go in the second box. If you examine the pictures, you'll notice there is a circular label on the very bottom(Upside down lid) of the first box. Also, the warm air might pass to far to the side of any ice packs in the bottom box, while the fan pulls it from the side holes. Hence the need to place them directly over the air flow passage. :D Hope that helps
I'm confused by a couple of the pictures. Can you please explain what is in the bottom box, and the middle box? Is the ice pack in the bottom box and a small bottle of water in the middle box?
Nice work. Although it should probably be mentioned that a USB port will only supply 100mA at 5V DC to a device without communication - a process a called enumeration is required to source more current from a USB host. That should be taken into consideration when picking out a motor or fan for this project. USB hubs were never designed to be DC power outlets, so using them as such requires a bit of finesse.
