Clearer schematic and block diagram added

A project log for Dual TLC555 Capacitance Meter 0.1pF Resolution

Two 555 timers turn capacitance into an analog voltage readable on a DMM. With a modern 600.00mV scale, that is readable to 10e-11F.

I have redrawn the schematic so it is more clear. I also drew up a block diagram with waveforms and explanation of circuit operation.

I welcome questions and comments.
