OK ...Here we Go again...man... I Love Contests. Some Day I found an Old style Bike lamp Powered by a Kind of Dinamo but it was broken, anyway I Buy It, and become to think what the heck to do with this stuff.
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..."
This Lamp is so usefull because the battery support about three days that constanting Light.
I like to ride with some folks in the deep of the night and its so cool when my bike hit the streets.
