| Hello everyone. i'm wanting to use my mobile phone, with an FM transmitter, to play music thru my car stereo. Now i have a 12v transformer plug that provides various voltages (7v i guess is the one i'd need?). I need to split this into 5v (890ma) to my Nokia phone, and 1.5v to the FM transmitter(usually uses 1 AAA battery). would anyone be able to advise me on this? thanks very much Jon. | |

| Do you need transformer? Doesn't you car produce DC? I think you can use voltage regulator; 7805 for 5 V and LM317 for 1.5 V. Are you going to plug you earphone jack from your phone to the input of the FM transmitter?
