Default Need a small mp3 playback device

Hello all!

First post here but I have dug through the forums to find my answer (which was none).

I'm looking for a small device that can playback a 60 second MP3 sound-clip. It has to be thin (1 inch or less), have a one-button play feature, and have an 3.5mm output to power a pair of powered NXT speakers.

Any ideas? Most of the stuff I found are full-blown MP3 players and I don't need that much. I know playback chips exist as my daughter's stuffed bear signs a song for a minute but but I can't find a source online.

Thanks for any and all help!

Keith

Have a look at this one: USB Host Audio Decoder ICs for USB/SD Audio Players | New product new technology | ROHM. It's new... I made a PCB for testing it (with a microcontroller) but haven't populated the board yet. I made it to only support USB. It has both stand-alone pushbutton operation as well as uC interface.
If you want to buy something "done" check out SparkFun Electronics - Breakout Board for VS1033D MP3 and SparkFun Electronics - Breakout Board for VS1011E-L MP3. I haven't used either of them (I know about them because I was looking at using the VS1033 at one point).

EDIT: This one is "finished"; ready to go... don't know if it fits your size constraints... http://www.sparkfun.com/commerce/pro...oducts_id=9715

Good luck.
Mike T.

Thanks for the quick reply Mike! The pricepoint is a little high and it looks like it still needs a 3.5mm jack added to it. I'll look into it but will keep my eyes open still.

Thanks!
