Made with standard size resistors and capacitors.

For the top-right potentiometer (output voltage): Slide left to create oscillations that will decrease in amplitude over time.  Slide right to create oscillations whose amplitude will saturate the op-amp over time.  Slide to 50% to create oscillations with a steady amplitude.

For the bottom-left potentiometer (frequency): Slide up to increase the frequency of the output voltage.  Slide down to decrease frequency.  A 10 kHz frequency means the slider is at 10 ohms (1% of slider).

For the output voltage potentiometer set at 500 ohms and frequency potentiometer set at 10 ohms: Please do not adjust the time scale greater than 200 microseconds, or else the frequency will change and the amplitude will go to zero.

Holding down the push button for different lengths of time will change the amplitude of the output voltage.
