Instructables
Since I read a book of electricity and magnetism I have been interested in the topic, and now I have the opportunity to share with you a super easy mini ecologic generator (MEG) I invented the name. You can use it to recharge a battery, power up a led and make a lantern, make a wind generator, attach it to a bicycle or to a car for illumination and many other utilities. All you need is DC motor (between bigger more voltage will give) some big capacitors, diode, and if you want a better mechanism you may add big gears.

One day Oersted saw that moving a compass in an electric cable the needle moves as soon the currents flows, Oersted concluded that an electric current produces a magnetic camp.
Oersted think that if inverting the process he could produce electricity, I mean moving an magnet between a cable or moving cables between an magnet produces a flow of electrons or electricity, this is the principle of the Mini Ecologic Generator (MEG).

Step 2: Diode

If we do not use the diode there will not be current for what we want, we attach the diode in the negative pole of the motor.

Step 3: A little battery

For this step we are going to use capacitors(we need big ones) this will make that save some current in the system, solder all the negative poles with negative poles and positive with positive.
 
Believe it or not we finished our MEG all you need to do to produce some electricity is spin the wheel. Now you can use it in any system that spins for example: attach it to the wheel of a remote control car or in a common car, you can make a wind generator with recycle materials (you can use cardboard for the blades, I made this with big motor and you can illuminate your house).

what kind of diode do i use ?

Ger de la Mora (author)  latios217 months ago

A common zener diode

thank you! I can't see clearly in the photo if its a zener or rectrifier
