So what exactly would I be looking at on the screen if I opened up my ESM1
and instead of ruining it (just a comment on my soldering skills or lack
thereof), I miraculously was able to solder two wires to the right PIC pins
and to ground (I assume) and hook them up to a miniature (or is it submini?)
stereo jack. Would that output feed directly into the AUX input of a sound
card, hopefully one on a laptop?
