Portable Airconditioner (USB or battery)

This simple instructable is designed to remove the HELL out of your desk, or bed, or whatever. if you have a PC ors mall power supply fan lying around and is used to take a cheapo slurp at 7/11, then this is for you! easy, simple to make, and you can also apply some salt to taste (REALLY?!?) for thermodynamics to cool air further but your poor ice cubes melt in a pool of cool, salty water.....

Step 1 Gather the materials

you will need the following things:

Ice
A place like hell
fan
cheapo slurpee cup
a power source ( your neighbor)
cutters or scissors

Why the salt? It makes the ice melt faster.

It also drops the freezing point, therefore it might melt, but it will get colder. That's why you use it in old ice cream makers.

From my experience: DO NOT let them kiddies stick them little fingers in there. Two things might happen, 1) Jam the dam fan period; 2) Get a tiny slice on your finger/s. I just stuck my little pinky in there and now theres a hideous patch of calloused skin on it..... oh wait it dropped off. Still, it hurts first time, everytime! so recommended: put a safety thing in there just in case.....

the fan has safety. the fan will stop when jammed and restarts after 3 seconds

don't you remember? mine didn't

[nutsandbolts_64]

hehehehe, I'm gonna make a, a, a... oh dam I forgot :( NOW I REMEMBER! okay, I'm gonna make a good fan which is driven by... A TAMIYA MOTOR!!!!! those motors are insanely fast and powerful for their size. besides, I'll try to make one of those sterling engines. I'll drive the engines instead of the engine driving something. It reverses the... nah I'll just use a peltier unit... nah... nvm

use the phone jak it is at like 50v and its free!

[beehard44]

 well, all you need for that is:
4 Diodes
12v regulator

Ask google on how to make a bridge rectifier.
Then wire your phone jack to the AC inputs. And your Regulator, check the datasheet online. Usually the center lead is negative. One of the other leads is input and the other is output.

Not a lot of current available though, hence the very thin wires.
