Donald,As you know, a stroboscope is a special kind of light that
flashes in a very regular way. Each flash of the strobe light is the
result of an electrical discharge (sort of like a spark) traveling
through the special gas contained in the strobe "flash bulb". The way
this works is very similar to the way neon lights work...the electrical
current flowing through the gas causes it to emit light. The main
difference is that in a flash bulb the discharge happens very quickly,
lasting only a tiny fraction of a second.The main parts of a
stroboscope are the actual flash bulb filled with the proper gas (Xenon
or Krypton), and the electronics to send a high voltage pulse to the
bulb at regular intervals. Several hundred volts is required, and this
is usually obtained with a ting oscillator circuit. (If you have an
older electronic flash for your camera you can often hear it whining as
it gets ready to flash...this is the sound of the oscillator used to
charge a capacitor to a high enough voltage to cause the bulb to
flash).I'm not sure of how much detail you want...
I found a pretty good web-site that you should check out:http://www.hut.fi/Misc/Electronics/circuits/strobo.html
