You cannot use IC LM7805 because his operating voltage is 7 to 20 volt. If you add a silicon diode(example 1N4007) the voltage will fall 0.7 volt. Nice project !!!

That's very easy , thanks for photos too,.. but i think you should put IC 7805 (voltage regulator) to regulate voltage because for many phones' battery 5.5 volts may be high !!

its really nice project but i think u should add 5v regulator in it.:)

WOW! Thats definitly nothing you should connect your phone to!
5.7V is too much for many charging logics and it might ruin your cellphone.

In addition, many phones require a minimum current supplied, which can not be guaranteed when using direct sunpower.

Its far better to use a regulated voltage to charge a cellphone, also you should buffer the energy to stabilize the voltage and prevent a permanent on/off when clouds hide the sun.

This is what i did: Article
Its a charging controller with LiPo packs, charging over USB or Solar Panel and giving the energy to any USB-Device plugged in when its needed, not only when there is sunlight.

Although the CD-Case-Panel looks nice, its not recommended to use.

I think you meant solar panel not battery. It's a neat idea

Right, sorry for that ;]

Sounds nice and simple! Where do you get a solar battery? Is it hard to hook the USB to the solar battery?

Polish version of e-bay :
It's not hard ;)

Mobile phones are picky when it comes to the charging voltage. Also, the charging current is definitely bigger than your solar cells. I wouldn't use it on my Iphone. Hint: use them without that plastic lid on. The charging will be shorter.
