neat little design, made one just for the fun of it and because the a/c in my house doesn't like to fully cool off my room so it helps!

also i don't like all the messy wires so i did abit of cable management and was able to get them all inside, and made a small hole in the handle of the coffee can for the usb to come through

also had a simple on/off switch laying around, hooked it up, works amazingly

only took about 10-15 minutes, fun little thing to do at almost 2am :P
Freeze Saltwater, get ice that is cool for a longer time.
think someone stole your idea xD

And then you fuck your USB controller because you've got no flyback diode in there.

Possibly some bypass capacitors to boot.
[QUOTE=Justin Case;36951666]I'm assuming the soldering goes like this
Fan -> USB
Blue -> Blue
Green -> Green
Yellow -> Yellow
Black -> Red

because this discussion is confusing me[/QUOTE]
The only wires you need are the black and red wires. The other wires control data. And unless you plan on making your own program to control the fan speed of a ghetto air conditioner, you don't need to wire them together.
Yes, a 120mm fan normally runs on 12v, so running one on 5v will make it run a bit slower. You could technically use a 12v battery pack, but the idea is to eliminate the need of batteries. Or, what you could do if you wanted to get more in-depth, use a relay to detect whether or not it's plugged into USB. If it is, it shuts off the battery pack, if the cable gets unplugged the relay will switch to the battery pack.

Honestly, this is a fairly basic idea. I can guarantee someone has done this before me. However, kipkay generally just looks around for ideas online then makes over-simplified videos about them. It does frustrate me how he makes it seem so simple for someone to do, most people want to make his projects with little to no previous electronics experience.
You should also add some insulation around the inside of the container to make the ice last longer.

That kind of defeats the whole point of this.

The idea is the ice melts and gives off cold air that is blown out. Try to keep up with us...
Actually he kind of has a point. You want the air moving through the unit and over the ice to be losing heat to the ice, but do you really want to cool the stationary air around the sides of the container? You might find your ice lasts a little longer with no noticable reduction in cooling if you follow his advice.

To simplify this, you want the air inside the container to be cooled, not the container itself or the air around the container. Any coldness that isn't in the air inside the container is wasted coldness.
On the rare occasion I actually mind the heat, I just set a little 24" desk fan in front of a tub of ice/icepacks v:v:v works fine for me...
Why do you people even need icepacks in the summer? I live in Texas and in the summer it gets up to 110 sometimes and all I need is a plain old fan, no ice. This is a nice little gadget but I just don't see what you guys need ice for.

Because dry heat is a LOT different than humidity.
