DIY Safe-sync |
|
|
I am excessively poor at the moment, and would like to use my Powershot G6
in a studio with a PC Sync cable. I'm not sure just what goes into the Wein
Safe-Sync, but would I be at all likely to fry my camera if I just used a
1.5v battery with a solid-state relay on my hotshoe to trigger the strobe?
I'm pretty sure its voltage isn't too high anyway, but I think it might be
higher than 6v.
Does anyone know of this being done before, or which pin on the hotshoe is
+ve and which is -ve? Also, what is the safe current rating for a G6
hotshoe?
Thanks for any help

I have no idea actually; I was going to start looking for an approriate one.
You wouldn't happen to have any recommendations, would you?
I would just use the camera flash to trigger the strobes, but there are so
many situations (especially close-ups) where this could cause me trouble.

Perhaps I was mistaken, but it didn't sound like he had anything but the
onboard, which he probably can't switch out of TTL even if he wanted to.

No dude, it's a Canon Powershot G6, so I can put the flash in manual mode
and make it do what I want. I have been using it to trigger the strobes for
a long time, and am getting a bit sick of it :-)

The fact that one way or another it would affect the picture I was taking.
If I didn't deflect it, I *had* to have frontal fill (and I couldn't use
low
power either or it didn't trigger the strobes). if I did deflect it, I had
to mess about with bits of tinfoil continously, and it can still make it's
way into the shot sometimes.

That does sound like a pain in the rear end. I used some elinchrom
strobes a week ago, triggering them with my Sigma 500 DG Super - even
bounced off of the ceiling at 1/128th power, the elinchroms fired every
time. If I'd had to go through what you've been doing, I would have pulled
my hair out!

Interesting... about what I would have designed. Question though... where
would one obtain hardware for male/female hotshoe connectors? Seems silly
to buy a
cable only to cut it up.
|
I got the female connector from an old camera with a hotshoe that i got for
$1 in the Salvation Army Store. The male connector should be easy to make;
it's just a flat bit with contacts on. I could probably just make a PCB with
the right contacts on it.
Of course, we'll see how practical that is soon enough, but for a grand
outlay of $4, I don't think I'll be too upset if anything doesn't work out
:-)
