>>>Well, all the camera will see is a nine volt battery feeding the gates of
Perfect. And very similar to what I did with a similar circuit a few
years ago. I had to parallel up to twelve 2400WS Speedotron flash
packs and they all had high-voltage, high-current sync circuits that
were frying the sync circuits of a couple of cameras. I ended up
using a 9V battery and a MOC3023 with a R/C network on the input that
pulsed the triac when the camera fired. The flash sync circuits
dropped to zero volts when fired so the sync stayed "ON" (shorted
through the triac) plenty long enough to work for just about any flash
unit out there, and turned off by itself when the sync voltage dropped
far enough. And I didn't need a 555 to create a pulse.

1/8" audio plugs sound great...darn inexpensive and the soldering
should go quickly.
