Introduction: Not So Throwable L.E.D. Generator

About: interested in most all the things mentioned in this site, and willing to try most all the projects...

simple project that can be used to show the capabilities of wind energy
or just as a simple momentary flashlight.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

you will need a :
L.E.D.
a small hobby motor

Step 2: Tools

you will need a:
soldering iron
solder
snips / scissors

Step 3: The Easiest Step

solder the led to the motor, polarity does not matter since the polarity given off by the motor switches with a change in rotational direction.

Step 4: Tips

possible applications for this include:
momentary flashlight
placing on a small propeller to demonstrate the potential of wind energy
a tachometer, the brighter the led is the faster the shaft is spinning

    the polarity will matter if it is a DC motor...

    .if you spin it the opposite direction the charge reverses

    that would be great for (some) bipolar LEDs!!!! just reverse the polarity and its a different color!

    can some explain how this work. What i mean is where do you connect the leads of the led on to the motor. And for the led to light up all you have to do is spin the motor?

    Please trust in the fact that this will never ever work... I have tried many many combinations of everything you could think of ie.. air,water,solar... Nothing produces enough energy to power itself back. It just isnt possible with the technology we have right now.. You can however get minimal results with a combo of generator powered by solar turning another generator by belt to power a light. But as others have noted you lose alot of energy in heat which sucks.

    im confused.. in this design, we would need wind for 5secondes, then it would be auto-power-making system! i was kidding btw, dont even try this lol

    This would be true, but sadly you would need more energy to rotate the blade then you would get back due to physics, and two you lose energy in heat. Sucky isnt it.

    u can't make anything like that, because there is no(or at least I never heard of) device that produce it's own fuel(well the sun one though, but not man-made for sure) as for your design, wouldn't it be better to use one motor, a capacitor and something that would crosswire the motor and capacitor so it can still spin (otherwise, it would spin backwards with the power from the capacitor)

    solar power is free. except 4 the solar panels. lol.

    No device can produce "free" energy, except by splitting/fusing atoms
