[sdiy] Being accurate

[Paul Schreiber]

Hey! Not a bad guess. Not exactly coreect, but 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).

Paul S.



  Amplitude 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.

  So what did you actually do?  +100C is pretty damned hot!  (Cool day in Texas, though.)

  Peace.
