Portable Cooling Fan for in the Classroom (flashlight Mod)

Intro: Portable Cooling Fan for in the Classroom (flashlight Mod)

This is my first instrucable so please don't be harsh with comments.

This is a portable cooling fan to cool you down on a hot day when your teacher just refuses to turn on the air conditioner (or just doesn't have one). You dont have to add any switches or modify the battey compartment, and best of all, it works!

Step 1: Materials

You will need:
.small motor
.small fan
.old flashlight
.small amout of insulated wire
.wire srippers
.soldering iron
.hot glue gun and glue
.2x AA Batteries (rechargeable recommended as they can be re-used)

Step 2: Dismantle Flashlight

You must open up the flashlight and completely dismantle the bulb compartment. You will see where the bulb connects to the battery compartment (there are actually two metal points, look closer), this is where you will solder your wires to.

Step 3: Soldering Time

You must now solder wires to the two points of the buld compartmant and then to your motor (you should easily be able to find which is positive and which is negative).

Step 4: Put It Back Together

You now need to put your flashlight back together, but without the clear plastic cover for the bulb or else motor will not fit. If you find this difficult you may just need to push a little harder.

Step 5: Make Sure It Stays There

Use your hot glue gun to keep the motor in place inside the case. Now place a small amout of hot glue into the little hole in the fan (to make sure it stays on the motor) and QUICKLY (or may not work properly) place the fan onto the motor.

Step 6: The Portable Cooling Fan in Action!

Thats it! Now to test it.

    actually the hot glue works perfectly. you just have to wait until it drys before you use it.

    Ooh, it used to get SO HOT in my high school classroom. The worst was that I would go to two different schools during the day. One was air conditioned and one was not, so it was impossible to dress appropriately!

    Good work, Eddy. I have used these hand fans that are bought, and I also had to make for it a new propeller. One caveat: the hot glue has no sufficient grip to maintain long time the propeller in place, and if it goes flying, you can hurt someone in the eye. I suggest you use super glue or similar for it.
