Step 1: The Flash Light

This kind of flashlight work with the action of a dynamo by the movement of the wheel, but it was broken so I dissassamble the whole thing an add a pair of Leds.

Step 2: Power Up.

Anybody of us have in our stuffs old cell phone batteries, so i figure that this can be usefull to power up my Flash light.

Step 3: Wiring and soldering.

Put the Leds inside of the Lamp and solder to a thin wire, conect to the battery and that `s all...piece of cake isn´t....?

Step 4: "Im the NightRider..."

U know something ...i dont have a clue about electronics but still working ...I used battery of cellphones and two leds of 3 volts...that´s all.
I had been used this about a year and still lightning...I think is good luck. let me do the Math and I´ll give you a better method...BTW...thnks for the vote
