This L-C meter project can be found in http://electronics-diy.com/lc_meter.php
is one of the most accurate and simplest LC inductance / capacitance
Meters that one can find, yet one that you can easily build yourself.
This LC Meter allows to measure incredibly small inductances starting
from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from
0.1pF up to 900nF. LC Meter's circuit uses an auto ranging system so
that way you do not need to spend time selecting ranges manually.
Another neat function is reset switch that will reset the initial
inductance / capacitance, making sure that the final readings of the LC
Meter are as accurate as possible.
