Diy Led underwater flash strobe

The pins on the hot shoe are simply shorted. Take care of the max. voltage for your camera's hotshoe, though.
I don't know what LED you're using, but you might try the IR led for remote controls. My Yongnuo flashes, for example, are easily triggered by TV remote, even from one meter or more...

Not much help unless you are a boffin but it seems that pins 2,3,4 & 5 are for digital serial communication with ETTL strobes rather than simple high/low status signals. They communicate stuff such as aperture, focal length, shutter speed. ISO etc. Top left is the data clock, top right & bottom left carry the data.
EDIT - Here you go :-
Hello, do you know where I could find iTTL specifications for Nikons?

Yes they are trigger like flashes (short duration pulse ) the caps are regulars nikonos protectors caps.
Thanks and happy dives
Any ideas to increase pulse width up to 20ms (1/50)? I can use a small macroprocessor for doing it.

Yes you can control the amount of light by adjusting the pulse duration
