Triangular wawe generator

Give it some noise and it starts working (or wait a few seconds and it starts working by itself). 
This circuit generates a triangular wave at his output. This is a generator there is no input.
If you change the values of the resistors the frequency changes.

The output wave has a period of:

T = 2RC * ( (Vs1 - Vs2) / Voh)

R is the value of the upper resistor

C is the value of the capacitor

Vs1 and Vs2 are the threshold voltages (in this case 4.71V and -4.56V)

Voh is the maximum output voltage of the op amp (in this case 15V)
