Happy New Year everyone.

Dwayne, thank you for the detailed description, I am looking forward for
more details later.

From what you describe there seems to be a lot of hardware involved ...
I'll probably try it the nasty way:

A/D less PIC, sensor transistor mounted as common emitter amplifier and a
cap between C and gnd, and a R to a PIC IO pin. And a good quality voltage
regulator (a Seiko probably). Maybe I'll replace the PIC side resistor
with a JFET, and bridge it with a large R, this has worked well in the
past (with Up < 2V), to improve A/D linearity.

How much precision did you achieve ?

thanks,

Peter
