MPE3 + Solar + External Speaker.....

[Resus12]

Hi,

I would like to build the following:

- an MP3 Player
- powered by a solar panel
- external speakers which ( 22khz is needed )
- the whole device needs to be as small as possible.

Aim: I am using audio subliminal messages; they work really well. I need this MPE circuit in order to play these messages on a loop powerded by solar
and as tiny as possible in order to integrate the device somewhere I can forget it.
I is a kind of self-tricking

Has anyony any idea how to build my device?

Kind Regards

Some MP3 players that drive earbuds use low power and can be powered from a solar panel. But the solar panel must be pointed directly at the sun which is impossible at night. What about on a cloudy day? Then the solar panel must be HUGE.
