Tuning LED a la Tivoli

[tubenut]

Hi all

I would like to put a nice blue LED on a "Eveready Power Blaster" FM battery radio for my little boy. There is plenty space in the case and they sound OK, not like my Tivoli but that cost 25x...

Anyway, I then wondered, how hard would it be to add the orange tuning LED like on a Tivoli radio?

I know my way around some amps and CD machines but RF/tuners hold lots of mistery.


Thanks

Hi,

I would assume its a case of the chip having a drive pin for the LED,
and if so what has been done with it. If the chip has no relevant pin
then there is nothing you can do to derive the drive.

Thanks sreten

Downloaded the data sheet, it is an Atmel "portable radio" on a chip. Has the LED driver, I will probably also acivate its soft mute and add an input for IPOD as there is a tape input pin to the audio pre amp and use the socket switch for input switching selection.

Thanks
