RC oscillator?  Shake your phone to start. 
freq is 1/(2π✖️50000✖️0.000003)=1.06/s
That light bulb is getting brighter and brighter. 
The RC self-oscillator circuit requires noise, and the noise that shakes the phone only has a single frequency. So not every RC combination can take advantage of this noise.
