Well, I made this generator, a year ago in the science fair at my school, although this was not the first place was pretty well the project,
And now I want to share with you, I hope you enjoy it.

These are the materials you need:

• LED (light emitting diode)
• Engine 9 to 12 volts
• Engine propeller
• Pedestal to hold the engine.
• Multimeter
• Copper wire / tin
• Terminal strip
• Connectors N / N
• Hair dryer or compressor


1. You must have ordered the workspace.


2. Drill some holes in the pedestal, to put the wire, which will help to sustain the dynamo to stand straight.


3. Carefully, you must solder the tin to the motor terminals, which serve for the passage of energy.


4. Attach the propeller to the generator through a plastic tube (test whether the propeller to rotate easily once attached).


5. Attach the cables to the support column with electrical tape.


6. Connect the wires to the connector terminals and adjust all cables to make good contact.


7. Once the generator is ready and assembly, proceed to do the first tests.


8. Turn on the dryer, which will move the propeller causing the flow of energy that will allow us to turn the LEDs.


9. Finally we can do a test to measure the voltage which is applicable to generator, using the multimeter.
