PIC based mAh meter/current draw sensor

[skimask]

You need current flow, so from the 0 point input to your regulator put the shunt resistor with an op-amp and then the ADC. Even better, Analog has such current sensors already made with op-amps and the rest in one chip (AD8210).

You don't have to mess with the regulation loop of the regulator and sense lines. Work on the input directly after your rectifier/capacitor.

I don't think it's complicated, but that's just me...and I want to get to experience with this type thing anyways. I know Analog and National and a bunch of other have chips, just plug and go and you're done...again, I want to play a bit.
And I pulling power out of a battery pack, no rectifier
Basically, I guess I'm looking for confirmation that I'm on the right track.
