LC Meter using a PIC16F628A

Due to the number of coils I've been winding for crystal sets, I needed an inductance meter to measure them and make sure the theoretical values I was coming up with were within the rough area of reality.  I looked around at commercial meters and gave up - being a student at the moment means I didn't have the funds.

Then I stumbled across the LC meter built by Phil Rice:

First Play with a 16x2 LCD with HD44780 Controller and a PIC Micro

I've been playing with PIC microcontrollers for a while now - I started because I wanted an inductance meter to measure coils for the crystal sets I am making... and googling led me to this circuit, which seemed fairly simple... and from there I fell headlong into microcontrollers.
