you are getting the general idea (it was a 200Khz signal, and each reading took
8 seconds to calculate using a 68HC05 uP running at
1Mhz).</FONT></FONT></DIV>

stabilized oscillator driving capacitance under test, then convert AC current
passed, to capacitance? Would probably need 100 KHz oscillator and some
fancy footwork to make that $25 price tag. Don't know if that would do
it but am fresh out of guesses.<BR><BR>So what did you actually do?
+100C is pretty damned hot! (Cool day in Texas,
