Step 4: Final thoughts...
I have a slow motor from a ps2 controller and lets say it doesn't work too well...
Also just to tell you all, this only works under water. so make a long cord attaching to the battery, and don't leave it in the water too long or it will rust and not work anymore..
Questions you may ask.
Q. It doesn't work!
A. is the motor working? impeller stuck?
Q. It doesn't go as high as i thought.
A. are you under powering it? try 6v or 9v..
Q. why would i need this?
A. you can use it to pump water for computer water cooling or anything you want.
