Hi, im attempting to create a device that charges a mobile phone through wind whilst attached to a bicycle.
I have quite a basic understanding
on electronics which is why i need help so here goes...
I have 4 motors/generators that can produce 0-12v each but on average whilst tested produce approximatly 2v each whilst cycling at normal speed.
I have managed to power any 5v phone with 4 aa rechargable batteries hooked up to an x in car usb phone charger that i have taken apart, but i cant figure out how to charge the batteries from the potential 8v i can produce from the small motors/generators.
I cant seem to figure out how to get the combind voltage from 4 motors, does anyone have any ideas? What ive got so far is hooking them up in series with diodes so they dont power eachother but the two ive put together so far only produce the voltage from one which is about 2v. Basically, if i have a hairdryer blowing a small fan connected to a motor/generator and that generator is producing a steady 2v, i want to then have another generator hooked up to that if i twist it for example and it produces 1v, the overall reading will be 3v. If that makes sense?
Im very frustrated and stuck so if anyone has any help i would be extremely eternally gratful!
