Hi Terry,

I had been looking for a way to easily check my SRSG timing so I built your
LED strobe and it works great! Thanks for posting the schematic.

Hi,

You can't use just straight AC since the sine wave voltage will spear the
image.  You need very fast bright "short pulses" to freeze an object's
motion.  Here is a simple circuit for an LED strobe that works ok.
