Hey, its the noob again =]
Well, I have a few garden light solar panels here. Each one has it's own NiCad battery (1.2V, 600MAh)
My cellphone charges @ 5V.
From what I understand, I would need at least 5 solar panels to get 5V+ to charge the phone.
BUT this puts me at 6V. So, I'd need a linear regulator. I've already assembled the panels and tested to voltage, and all is well. But I need to know where I put the regulator!
There is the +5V Fixed-Voltage Regulator 7805 at radioshack, but I guess they need a minimum input voltage of 7.5V to put out 5V. Is that correct?
And assuming I can get 7.4V, I still need to know if this will work with the regulator...
Sorry if I left out any essential info. I appreciate your help!
