Xenon Strobe

This is a very simple strobe circuit which I have not seen anywhere else. My inspiration came from a strobe circuit that was in a school fire alarm buzzer – the kind that has a built-in strobe light on top.

Description:
It’s a pretty simple circuit which some of you may be able to figure out, but I’ll include this description for beginners and others of you who may not be as familiar with the characteristics of Xenon tubes.
As the power comes in, it passes through the large current limiting resistor which we will refer to as R1. This resistor’s purpose is to prevent the current input from the AC line from maintaining the arc in the Xenon tube. If this did occur, the high current would place excessive wear on the electrodes. Also, undesirable metal haze would be deposited on the inside of the tube which would reflect heat back and further shorten its life.
