This circuit is a simple circuit using only capacitor C1.Resistors R1 frequency generator to Q1.Which acts like a switch.then used Q2 to be the current increase.
Operation of this circuit from capacitor C1 through R2 and LED1. Until the voltage drop at C1 increases,Q1 to the value that work.
As a result, the current Q1. The current through pin E and C stand to cooperate with the Q2 Q2 B’s conduct as a result, a current flows through LED1.While C1 is discharged through R1 to a period of time.When C1 discharge out there would be no pressure to bias the leg B of Q1. The Q1 to stop working, Q2 will stop working.LED1 will turn off and capacitor C1 will start again.The Q1, Q2 LED1 light work, where work is of such and so on.
