My first o amp circuit

There was a guy who built a circuit with no power source, it was powered by noise injection, (the circuit is called, shake your phone for light) lol , I was amazed tried to replicate the circuit many of time, which is not but but getting it without shaking your phone was,this is what I ended out with. There is still room for improvement.  Give it a little  jolt and see what happens.

Power in this circuit comes from the Opamp, the min/max voltage simulates the vcc+/- rails. Introduce a tiny amount of voltage disturbance anywhere and the Opamp will amplify it, and oscillation will begin. this is how it works in a real circuit too.

How to introduce voltage disturbance in real circuit?

If you are doing it on a circuit like this, try sound wave
