This electronics video tutorial provides a simple way to create an oscillator circuit using a 6V battery, an inductor, a motor, a resistor and a multimeter to test it. By the way, the waveforms generated by small motors spinning fast tend to very spiked distorted waveforms. If you wish to generate a sine wave with this circuit, use a larger slow spinning motor with an additional capacitor connected in parallel with the resistor. I was able to generate a sine waveform using the large motor shown at a time stamp of 2:20 while using an inductor of 10 mH in place of the transformer and an additional 220 uF across a 1K resistor. The 220 uF resonated with the 10 mH inductor and the inductance of the motor creating a decent sine wave. It also served to filter out any high frequency spikes that may have been produced in this circuit.
