Yes, that's it. Thanks.
Do you know offhand if it can link the Ultra's together and still use the 7" stock reflector on each unit with the above coupler in the middle, or does it need to be used sans reflector if they are coupled in a bank?
I did find a simple sequencer circuit here:
http://www.allaboutcircuits.com/vol_6/chpt_7/6.html Might fire up to 10 strobes in sequence if I can figure out the timing (Maybe astable vibrator frequency off the 555 at 0.003 seconds per cycle.). PC socket in place of the Trigger on the 555. Don't know about the hotshoe cable from the flash head to each LED out of the 4017 decade sequencer though.
Looks cheap to build though compared to the other link. Just a lot of flash heads, maybe 8 heads into two Vagabond mini's might get me a one second flash duration to keep from freezing the water as with one flash.
