The capacitors on this circuit determine the frequency that this circuit can detect. We can adapt it to work as an interesting shield detector for logic signals.
This 1992 circuit has a diode normally replacing the diac that is used in this type of...
This oscillator was found in the January 1996 issue of Electronics Now magazine. The frequency is given by...
This circuit divides the voltage of a source by 2, allowing its use as a symmetrical source. In...
