Hi all
i'm new to the forum and need some help with my son's science fai
project that I thought was going to be a no brainer.
The project was a simple wind turbine to generate electricity to mayb
power a little led light or something. I read online we could use
little dc motor to do this...well yes it works but the blades do no
spin fast enough to make enough electricity to lite the lights righ
away.
So..i thought..why not run the motor to a set of rechargeable A
batteries then to a switch...and then to some little led lights. I
is the same idea as far as generating electricity..except it is bein
stored for later use.
But then i thought..if i wire the motor right to the batteries....wh
is to say the batteries wont keep powering the motor.
So basically...what i need help with is how to wire this...and wha
else do i need besides what i have which is
a 9-18v DC motor i think max is 18000 rp
2 AA batterie
some small 2 volt led light
a toggle switc
i know i'm going to need some sort of diode..but not sure what...thi
is where i need help...please!!!
