Ok, general electronics question here.
I want to build a mini mini wind turbine using a 6-9V motor as the turbine and a 9V rechargeable battery to store the electricity…this is purely as a demonstration of processes rather then a real application.
Now in my very limited experience, i guess i could get away with just using a diode if i wanted to go barebones and ignore the overcharging issue.
But thought it may be nice to include something like a led as a dump load?
Any chance of some help with what would make a good simple charge controller circuit for this tiny 9V set-up?
