Here's my 2 cents. Use an op-amp integrator to integrate instead
of the capacitor.  Have a photocell as the input voltage to be integrated.
This way, at the end of the day all you gotto do is read the voltmeter at
the integrator's output, and hit a reset button. The only thing I haven't
I haven't figured out is calibration.
