Cheapy Capacitance Meter?

Recommendations?

...Jim Thompson
Do you want to only measure the low frequency capacitance? At what
frequency(s)?

Do you want to also measure the ESR?

What accuracy do you want?

How cheap is cheap?

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.
