Introduction: Super Easy Battery Powerd Computer Fan
This is a really easy thing to make out of a bunch of recycled stuff. I had a bunch of extra computer fans so i decided to get some use out of them. Take a look. Sorry if this is not original.
Step 1: Materials
A computer fan (the bigger it is the more air it pushes)
A 9v battery
A 9v battery clip (thanks to the instructable on how to recycle 9vs i made my own)
Step 2: The Wiring
If you look at the fan there should be three wires. Some other fans have more.
First strip the wires so they dont have the computer connect thingy
The red and the black wires are the ones you need.
If you dont have red and black wires i guess your going to have to figure out which ones are negative and positive.
Wire the positive (red) to the red of the battery clip and wire the negative (black) to the black of the 9v clip
Step 3: Switch Design
Next i decided to find a place to put the switch.
It fits nicely where the screw holes were so i decided to put it there.
For this step you will need a dremel to cut the plastic so the switch will fit.
You will also need a drill to make the switch fit in the hole.
You will want to drill a small hole somewhere to put a wire tie in
The picture should show were i cut.
Step 4: Wiring the Switch
Next you will want to wire the switch between the positive wire.
Cut the positive wire and solder both ends to the switch.
Step 5: Your Finished
Ok now all you have to do is put a wire tie on there to keep the wires organized and your done!
I wanted to put in blue leds but i didnt have any.
Thanks for looking please comment

Hey, How long does a standard 9V battery last with this setup?
