Instructables
The DC motor is a ready made generator that will generate electricity. All that you have to do is turn the Axle of the generator using a mechanical outside source of energy .

To show that I dismantled a damaged HP printer and take  the  DC motor that responsible for paper out shown in pictures and connect it  to LED array ,  4 LED connected in a specific polarity and the other four LED connected in reverse polarity ,so when the shaft rotate on clockwise ,4 LED will be on due to  forward bias and the other  off due to reverse bias  and vise versa  in case of anti- clockwise rotation.

Mr. EE, I was just a Tech here, there, and yonder. Thanks for your efforts and full speed ahead on some more ibles. I try to always minimize the negative and Focus on the positive. Every ible has some positive about it. Critics please pay attention, May my words always be tender and soft, that makes them easier to swallow.Gyro.
