LC Meter : June 2019 Practical Electronics / June 2018 Silicon Chip

Hi
Practical Electronics and Silicon Chip have published a LC meter featuring wide range and self compensation for drift.

Has anyone built one of these?  Are they as good as the glossy magazine says?

Looks like a quick and easy build.

Bought the files  but never made it,   its arduino based and the code need only 3 libraries,  can't go wrong for a mere 3$ purchase

<EEPROM.h>
<Wire.h>
<LiquidCrystal_PCF8574.h>

just need to find 1% precision resistors

It works by putting the L or C in an oscillator, the freq is dependant on the DUT.
So by just measuring the freq, you can accurately determine the value.

That's a nice one,  but only for smaller (HF) L and C parts.
