Cheapy Capacitance Meter? Recommendations? ...Jim Thompson Go with a cheapy multimeter. I assume that if you cared what characteristics of the cap interested you or if you cared whether it had enough resolution for small caps or enough range for power supply caps, or ...or... you'd have said so. Many cap meters and dmms with cap functions don't range high enough or low enough for MY general use. YMMV. |

Sometimes I even put it in the food. Build one yourself using a PIC, for instance: http://sites.google.com/site/vk3bhr/ http://www.marc.org.au/ Which seem to be derived from the http://www.aade.com/ mentioned by Bill Sloman already. If your analog mind cannot digest this digital stuff, dig up some 555s and use an analog meter for the display: http://freecircuitdiagram.com/2008/0...55-oscillator/ http://www.electronicecircuits.com/e...citance-meter/ The latter is an old one I ever build myself. Even seem to have a PCB design somewhere. A real cheap one is described he http://talkingelectronics.com/html/CapMeter.html said to be a poptronics design. petrus bitbyter |

Hey, this is Thompson. Very, very cheap. A 555 coupled via Cx to a diode pump & moving coil meter. Actually, an oscilloscope and a function generator will measure capacitance. Or just an oscilloscope. John |

I did not pay for shipping because the total invoice qualified for free shipping. http://www.seeedstudio.com/depot/cap...#productReview Actually I bought 2 in error. I intend to make the second one into an AVR development board. I may need a new chip ($1.60) If this one is code protected... It is a very quick build. |
