What I want to do is turn my AM/FM/CD PLAYER Alarm clock radio into an iPod player.
So maybe have add a usb port to allow me to connect my iPod into radio flip a switch and have the internal speacker/AMP play out.
Maybe have it when the alarm goes off to play a song.
I need websites:
1) Pinouts
2) Schematics
3) Vidos on similar projects.
Any help would be appreciated. I have a couple of old alarm clocks.
This is what I have so far.
I coud not figure out how to use the ipod touch adaptor cable with thirty pins. So I'll keep playing and reading about it til I get it.
I did however get it to work with the headphone jack.
I found the IC responsible for the amp. connected the open wires from my headphone jack. Now when I plug in my Galaxy S3 Works like a charm.
When I plug my iPod touch it works too but has some static.
I plug the audio+ to pin9 and ground to 11

It's likely that the ipod has too much volume for the TDA1083 (it has 40dB gain).
Something like this should work, if you're happy adjusting the volume from the ipod rather than the radio:
I've tried selecting values that are a compromise that should approximately work for either the line output or the headphone output.
Note that you'll need to disable the radio audio, otherwise you'll hear it on top. In the datasheet it is a wire from pin 9 to the
variable resistor, but the actual radio may have implemented slightly differently. You could try to remove the capacitor labelled 10nF
in the datasheet (connected to the 120k resistor). If it is the wrong capacitor, put it back in again.
