Two LED Flasher by Gate of IC 4011

IF you want the small circuit two LED Flasher, I show this circuit.
The important part of the circuit is IC 4011 again, I used gate of IC 4011 (see image).
IC wired as an astable multivibrator generating a 50% duty-cycle square wave at about 1Hz frequency.
Two LEDs are flasher to alternate.
To change value C1 and C2 for other flasher ratio.
Detail more, Please read in this image circuit.
