Would anyone know where I could find a photographic strobe schematic. I have done much searching, but can only find visual effect strobes, no photographic. I have found several sources for xenon tubes.

They use a larger capacitor and manual, not automatic, triggering. Otherwise it's the same circuit.
You'll need to go back about 20 or 30 years to find magazines or books with such circuits.
The schematic is pretty much the same, except for component values. Essentially, just a bigger storage cap, and a manual trigger instead of the oscillator.
Good Luck! Rich
Try here. It is a circuit from Tomi Engdahl from Finland. It has a manual input for single or multiple flashes depending on your control circuit.
I have an older copy at

You might be able to convert a disposable camera for that purpose. You can get them either real cheap or for nothing at places that offer film development service. Beware of the circuit inside when you open it up. There's a capacitor in there that holds a hefty charge - you need to discharge it before messing with the circuit.

Photographic strobe? do you mean a flash?

Here: Kodak disposable camera:
Safety reminder: Don't forget about the main capacitor. It packs a wallop. Short/discharge that rascal before handling the circuit.
You can sometimes purchase flash circuits like those from a disposable camera at surplus electronics sales online for under two dollars.
This company might still be selling them:

Or you might just go to any camera shop that processes the film from the disposible cameras. They generally take the film out of the throw away cameras then ship them back to a recycling company. They will gladly give them to you to save the shipping costs. The best ones are the Kodak units with the yellow labels. I recently went to a Ritz camera shop and they were more than happy to give me 20 of them. I slipped the guy five bucks for his trouble and we were both happy.
I have heard photographers use the word "strobe" to refer to a photoflash device.

A flash is powered by a low voltage that is multplied into a capacitor until the volage is high enough to power a xenon tube, & can't be flashed again until a new charge has built up. A strobe has a power supply big enough to flash the tube as often as the user wishes (but within the limits due to heating of the tube.)
