That's the meter I bought and built last year. I works great.

Although it doesn't do the "R" part of LCR, one good, small cheap meter
for measuring very small L and C is the AADE L/C Meter IIB (www.aade.com).

If one is very careful, measuring to 0.1pf and 10 nH is perfectly
reasonable (lead precautions, etc.)  For small L and C it's measuring
frequency is in the 100's of KHz range.

It only goes up to several hundred mH and a couple uF (it doesn't do
electrolytics, but that's not a range where I'm likely to find or need
precision caps anyway...) but if properly calibrated (the one precision
component is trimmed) it has an accuracy better than 1% - at least when
I checked it against an assortment of precision L's and C's kicking
around.  In comparing it with my old General Radio 1650A, it agrees as
closely as one can read the dial.

Snipped...
