Hi:

I got a Honeywell Q313 series "750 millivolt Powerpile Generator" and 
have measured it's output when in one finger of a gas stove flame.
It puts out about half a volt at 100 ma with a 5 Ohm load (50 mw) and 
probably would produce more power with a lower resistance load.
See: http://www.pacificsites.com/~brooke/batt.shtml#Heat

Is there a circuit that would transform this into say 3.3 volts at 10 ma 
that would be suitable to power a PIC?

Have Fun,

Brooke Clarke, N6GCE
