Ah well, if thats the way you feel, I shall move on to pastures new.

Agreed the high voltage is applied to the triac, but the popular American version that requires no external voltage is connected to this high voltage by a resistor and 5 volt zener diode. if this diode went open the full high voltage would be applied to the camera switch. :thumbsdown:Not really. The high voltage is at the flash end, not the camera end. The only bit which will connect to the flash will be (I assume) an opto triac.
The connection at the camera end will be a low voltage input stage pulled up by a large value resistor (I'm assuming again). Not much chance of causing any harm.

You probably can, but then if it takes as long to get answered as my front door does...!You can make one from a cheap wireless door bell
Do not dismiss this idea out of hand, all the bits are there.LMAO

please read my write up again. The R+ line goes to the hotshoe switch via a resistor with a zener diode to ground.But only to the receiver. There is no connection between the flash and the camera.

and surely the sync speed on a doorbell would be too slow?
but its a wireless trigger?

Please look up the circuit on 'Sam`s Strobes" and you will see you are talking pooh:bang:Yes. The hotshoe of the flash, not the camera. It's the flash which has a high voltage from which you can derive a low voltage supply using a resistor and a zener.
Steve.
really steve, that I didn't know
I was working on only attaching the Tx to the camera and the Rx to the flash

Enter don`s, light lamp and strobe siteCan you give me a link so I can have a look? (I tried a search but can't find it).
