The 260 ohm resistor represents a high impedance phone speaker.This could be used as a conductance tester. If you wanna check a cable's integrity or something. Just replace the switch with the two leads for the tester. P.S. Dont try changing anything on the circuit while simulating. Its quite unstable and migg cause EC to crash

Btw you have to turn the speed down to about 10uS/S to get it consistent. EC won't get the oscillation right otherwise (the frequency increases as you decrease sim speed down to that point).

Shouldnt 100Hz be the correct frequency of the RC circuit (tau=R.C). So 100ms should be the correct timeframe.
