Wow!,projects to make for Pic micro,and AVR micro,the hard part is the Choice,which one?
Thank you Mustafa! these links an info will undoubtfully help many here at these Forums,an not just me. appreciate!

[Mustafa]

or this one?

Hi,
How about this one?
http://ironbark.bendigo.latrobe.edu.au/~rice/lc/index2.html
It is free and open source.

Hi Alexis,Yes thats the One ,Im looking for! Very good Infomation,Thank You! Rov

Hello ROV ,
the best lcr i have for the price and very very accurate is:
http://aade.com/lcmeter.htm
I have it for years and it is a very good LCR , i bougth it in Kit form
and at first probe it work , i check it with very accurate industrial coils and it gave me a very near lecture ...
Regards.
Alexis.

thank you for your response ta2ctp. I google up for LCR meter an many results,many from ebay? HongKong,an China sellers?
Want to make ,simple but accurate for winding home detector coils?an measure!for projects.Thanks!

LCR METER

Hi,
You want to LCR meter make me not one, but here,
google "LCMETER" If I make a call (for visual) will reach many diagrams and construction notes.
Best Regards.

Is the L.C.R.meter from Ian C Purdie(amateur Radio Fame ,VK2TIP) still available ??
the design by Neil Heckt of Almost all Digital Electronics.
This is very use-full for inductance/capacitance measurement with a micro! maybe for Coil design use?

Check out this link for a report on how this LC meter works. There is a link in that report that will take you to the web site where the comple schematic and assembly instructions are located. This meter measures 150 mH maximum. It uses high frequency to measure small inductances: 60KHz up to 10 mH and 20KHz up to 150 mH.

Hello BBSailor , Thank-You for posting . I checked the website link you posted and they are still in business and a lot of goodies at a reasonable price !! Good to see you again , and you also have a "Great New Year 2009" !!!...................Regards........Eugene52

Not too many "LCR Meter" schematics are floating around the internet . I found out that there is LCR meter information in a July 1998 issue of "Electronics Now" , photo is attached . I sure would like to see the article and the schematics , and also any other LCR projects . I guess they generate a frequency of 1 khz to calculate a unknown inductance or capacitance . Almost all circuits I have seen , use a PIC-Chip or similar controller. Anyone have a good LCR circuit schematic hidden somewhere ???................Regards..............Eugene
