The following guest post was made by Rolf Randby, a fellow DIY-er, who has two right hands (this is yet another manifestation of Darwin's Evolution - The survivor of the guys who make stuff instead of buying them). The problem which Rolf was facing, is how to build a hot shoe mount for a flash trigger he made. Instead of running to the nearest photo store, he came up with a pretty cheap nice solution, that involves taking a part an old camera. This is also a good solution if your flash does not have a pc-sync outlet, as many of the commercial radio triggers use a phone jack to send the signal to the flash.
So to start this project of you will need an old camera that has a hot-shoe mount. Those are available at a lot of junk stores for a dollar or so. This camera is going to be disassembled - faint of heart - beware!
The other parts you are going to need are:
The first step is to Cut the plastic surrounding the hot shoe to about 1 3/8" wide, 1 1/8" deep and 1/2" high. Be careful not to rip the wires going to the hot shoe! Cut to about 1" and strip. See the image below fr details
Carve a place for the female connector in one corner. Hot glue connector and nut in place. Solder wires, make sure center connector of hot shoe goes to the tip of phone plug. Use more hot glue to hold wires in place. The image below shows the jack, the nut and a bit of Epoxy putty (more of that soon)
Use epoxy putty to encase it all, trim before epoxy hardens! Paint black.
Total time about one hour. Total cost, less than $10.00.
See how the flash trigger connects to the flash via the mount in the next picture.

It looks like some mad
It looks like some mad scientist like Edison made this.
What do you mean "Solder
What do you mean "Solder wires". How? Where? To what?
Hot Shoe Wiring ..........
The two wires coming from the junk camera hot-shoe, do not cut these wires sort because they go to the new connector. You cant solder to the center pin because it is made of some metal that don't take solder and the plastic around it melts anyhow. Then the whole thing is ruined.
If the original wires are to short you will have to splice in enough to make it reach the new connector's soldering lugs.
Still didn't answer
The most important question is not answered.
what are the contacts that has to be shorted?
the rest -- is not important.
(I'm not going to ruin a camera but need to know which pins I have to short to have flash fired)
DIY Hot shoe adaptor
I have a Rebel XT , is there anyway to make a hotshoe adaptor with a PC port ?
