This is a complete 555 timer circuit , it work just like a 555 timer. From the research i had done, I tryed to base it on the circuit off the tshirt from eevblog (youtube). I have tryed to make the circuit the same as the 555 timer ic. From my understanding of a 555 this work just like a 555 timer. The output opamp is working as a inverting schmit trigger to clean the wave form up.
