A little while back I purchased a imitation off shoe camera cord. It looks and functions identical to the Canon OC-E3, but was a third of the price and had a longer cable. Still, that cable wasn't any where near what I wanted it to be so I set out to modify it.
Using ethernet wall jacks attached to both ends of the cable I can insert a regular ethernet cable to extend the reach. I have tested it with a ~20' cable and didn't notice any problems. It took 4 tries but I finally got it working. At first I didn't think I needed the shielding, which i now believe is actually ground, to be passed over the ethernet, but I was wrong. Then I had a few issues with the punch down of the individual wires in to the ethernet jack. My multimeter was very handy to figure out where the problems were located.
After doing this first one, i could probably put one together in 15 minutes or so now. Was fun getting it working and now I can ETTL high speed sync many feet from the camera without an expensive wireless solution. Additionally, I can still have the 580 act as a master without being fixed to the camera hot shoe directly.
The above image is 1/4000 @ f/8. ISO 400.
