Greetings,

I recently built an LC Meter, designed by a fellow called coreWeaver,
which he based on Neil Heckt's AADE LC Meter.

coreWeaver made the hardware Open Source.
His software is also Open Source, but is written in BASCOM BASIC, and
uses the AVR BASCOM compiler.

The LC Meter uses an Atmel ATmega328P-PU microcontroller, the one used
by the Arduino UNO.
However, instead of the crystal being 16 MHz, as is the MCU in the
UNO, coreWeaver uses an 8 MHz crystal.
Some of the components he uses were rather hard-to-find here in the USA.

More information about the coreWeaver LC Meter can be found here:

When I decided to try and build coreWeaver's LC Meter, I ordered the
PCBs from OSH Park:


They sent some very nice PCBs to me, and I sent one to Bruce W8BH.
Bruce built his and wrote a very nice document about his build:


However, the coolest thing that Bruce did was to write Arduino IDE
compatible code for the ATmega328P-PU.


I was able to compile and upload Bruce's LC Meter code to my LC Meter
and it works GREAT!

Neil Heckt, the designer of the AADE LC Meter passed away on August 19th, 2015.
The AADE LC Meter has been discontinued and is no longer available.

I think that the coreWeaver LC Meter with Bruce's LC Meter Arduino
sketch is a good replacement for the AADE LC Meter.
If you build your own radios, or any other electronics that require
hand-wound toroids, then you need a good LC Meter.
