Bourno's MPJA MP3 player hack
Crack open the USB part.
I tore out the push buttons
I then made a couple holes.  One to get to the - Battery side
(I removed the battery first before drilling)

The cover slot was enlarged before snapping back together.
At this time (1-27-07), I have only tested this by doing jumper
tests from this solder point to the battery DC negative.  The
above wiring should work the same.
A big thanks to Otaku at for telling us about
this $5 MP3 player at

This is going to be my hack version to control it
via a Parallax controller board.
The best way to control the MP3 player is to have the Prop-1 control a relay and the MP3
control points connected to the Common and Normally Open contact points of the relay.
