[video] Build A Super Long TTL Cord Using Ethernet Cables
A while back we posted a guide that shows how to build a TTL cord extender using Cat 5e Ethernet cables and plugs.
YouTube member Matthewrichey made a short video describing the process which is worth checking out.
If you are more proficient with a credit card than a cable RJ45 plug crimper you can get a pretty long (10m) TTL cord for about $36 at your friendly online book store.
If any of you folks out there had a try, I would love to hear how long you got your cable before commands to the strobe stopped working.
Lastly, if you wondered why you would need a long TTL cord, check out Syl Areana's super smart way of using a Canon TTL master strobe inside a softbox to control other Canon strobes OR David Hobby's Strobe on a Rope self-assist way of off camera flashing.

I've got a 3' cable that I cut and put ethernet jacks on. I've run it w/ a 300' cat 6 cable in the middle and ETTL still works. Never had a need to go farther.

This is genious!
I could not find the cost, but I it is definitelly a good alternative to the old-never-working-when-you-need-it PC sync option.
Great idea!!
This is an awesome idea! One thing though, Cat5 connectors have a strain relief built into them. a common problem, and resulting failure point is not properly cutting the wires the correct length such that when crimped, the strain relief crimps on to the sheath.
Here is an example of what I am talking about from my article, how to make a cat5 cable
This is a correctly crimped cat5 cable. Notice that the strain relief is on top of the cable's sheath (yellow)
The image below is an incorrectly crimped cat5 cable:
Notice that the yellow sheath is not under the strain relief.
I did the same with
I did the same with USB-Cable. Works fine till 10 meters and above. See here: http://www.knueppixx.blogspot.com/2010/08/diy-ittl-verlangerung-via-usb.html
Benefit: The USB connectors disconnects automatically when you accidentally pull too hard which the ethernet connectors doesn't
Using a sb600 and d90 ended
Using a sb600 and d90 ended at about 10m as well. After that, the ready light would flash when triggered, but the flash itself wouldn't fire.
