S-Video balum for RJ45 Network cable

In a previous Instructable, http://www.instructables.com/id/S5YML6MFLFHVHAP/ I created a cable to send AV over a patch cable. I have been working on a few variations to the theme.

S Video is a higher quality signal than using phono connections and Scart is a very convenient connection as it combines all the connections in the one socket.

The Scart diagram included is the break out side to the TV. Scart input is wired differently and is really easy to search for in the usual ways.

I have decided to just go for the s-video connection at the moment but I include the pin outs for the Scart if you feel adventuress.

You will also notice that I show a jack but i actually used red and white phono with a phono/jack adaptor on the pc end

Step 1 Tools Used

The tools I have used will be found in most tool collections. Side cutters and a blade for cutting and stripping wires. A soldering iron and solder all joints will need to be soldered.

I have a very small vice that I use for holding items I could really do with another hand though he he. I also find that a good light source can be invaluable. in the second picture the glare has made the desk look blue. you can also see on the desk an old ADSL filter that I had not thought of using at the time but I will come to that later.

step 1:- Connect the wires to the RJ45 terminal. solder each terminal. I found it easier to work from the back row and move away from me that way the soldering iron didn't burn any of the connections I had already made.

This is a cool project. I did this once. I would like to point out that this, however, is not a balun. (yes, its spelled with an 'n'). Actually, now that I think of it, a balun would be a good idea here. For those that don't know a balun converts from BALanced signal to an UNbalanced signal or vice-versa. Balanced would be like XLR audio or network cabling. unbalanced would be a phono cable. Generally anything twisted lead is balanced, anything resembling coax is unbalanced. you can do it with a small 1:1 transformer that has center taps.
