simple project that can be used to show the capabilities of wind energy
or just as a simple momentary flashlight.
Step 1: Materials
you will need a :
a small hobby motor
Step 2: Tools
you will need a:
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:
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
