Led blinking from 230V

My friend and i was needing a led blinking from 230V. Withoutt transformer ,without pcb ,just a led and few components

And this exactly what we’ve made!!

The operation of this circuit is obvious. Capacitor charge through 47k and diode ,when it reach 30-32 V, (voltage that diac starts operate), then start discharge through 270 ohm and led.Capacitor must be at least 40V. So simple.

Playing with 47k and capacitor, we can achieve different blinking periods. With those values you can see to the video the period of the led

You can see and video to understand the period

  1. YOU ARE AN ABSOLUTE GURU.IS THERE ANY WAY YOU COULD HELP ME DESIGN A RANDON FIRE FLICKER GENERATOR THAT CAN ALSO ACT AS A MANUAL DIMMER CONTROL SIMILAR TO AMERICAN MAGIC GADGETS FIRE EFFECT CONTROLLER.I NEED IT TO RUN OFF 220V AC AND MUST FLICKER A FILM LIGHT SUCH AS A BLONDE WHICH IS 2KW.IT RANDOMLY FLICKERS THIS TO CREATE A FIRE FLICKER EFFECT SAY AGAINST A WHITE WALL.PLEASE EMAIL ME IF YOU CAN HELP.ICAN PAY VIA PAYPAL FOR THE DESIGN OF SUCH A UNIT.PS I AM IN SOUTH AFRICA.CAPE TOWN.
