Hi.
I really wants to make an USB Charger for old type nokia phone. Let say, 3660 or N-Gage for example.
I once tried to connect it directly (adding one diode) from PC's USB port to the phone's charger connector. But the phone won't charge and says 'not charging'. It probably the software of the phone refusing some voltage and/or current combination that the phone receives.
There is 2 type of charger that this phone can accept. One is nokia travel charger that provided 5,6 volts and the other one provides less than 5 volts (I'm not really sure about this one).
Does anyone can help me ?
