Hi Mike:
I've received an email asking about where to purchase a crystal activity
meter and although I have a hand held unit, see:
http://www.pacificsites.com/~brooke/Xam.html don't want to part with it.
This is an older unit that uses PNP transistors. I'm now thinking about
how to build one using a PIC and to that end would like to see what's in
the subject article. So if you would email a copy to
mailto:[EMAIL PROTECTED] that sure would help.
The final product should be a hand held battery powered easy to use device.
Have Fun,
Brooke Clarke
