Hi All.

I want to make a Wireless based DSLR Camera Flash Trigger system. Some ques please:

-1. I want to trigger the flash using existing Wireless receiver in the market. For this Wireless communication is there any standard or protocol which all Of-Camera Wireless (RF) Flash receiver manufacturer maintains? So I can develop only the transmitter and use the same protocol to send Wireless commands to trigger flash?

-2. In case I need to design both transmitter and receiver then I need to use Hot-Shoe signal. Can anyone advice detail document how Hot-Show pin and its signal works? I did googled already but did not find much design in terms of helpful for electronics design.

-3. Is there any standard connector PCB Mount for Canon/Nikon/Sony Hot-Shoe male and female?

Thanks in advance.

Regards.

Just ran across this.  Is there a specific need for you to create your own?  I mean, there are some decent "budget" triggers that work quite well that are as cheap as $15 per trigger (such as the Yongnuo RF605 series, except they are manual and do not support TTL).  As mentioned in another reply, there really isn't a standard, as each mfr uses their own proprietary communications signals, unless you started working with perhaps some of the OEM stuff, like Nikon or Canon, and you can get your hands on some of the tools/info for developers third parties, but that is generally far more work that it's worth.

I'd say if you're just looking for cheap triggers, look at the Yongnuo brand.
