Pin Schematic For DIY HDMI Cables?

Hey 'Goners!

Let your video genius and knowledge shine through! I would like to DIY an HDMI cable, but one that serves ONLY for video signal transfer (audio is processed separately using the 'audio out' jacks from the player to my sound system.) What are the best connectors and wire for this VIDEO-ONLY application, and most importantly, where can I get a schematic showing the HDMI cable connector pin pattern, specifically the functions of each pin connector and MOST ESPECIALLY which pins are needed for video transfer? I do NOT want audio or other non-video related signal pins hooked up, I just want to make a video cable that will ONLY send the necessary video information from my player to my TV via the HDMI interface. ALL of the other pin connectors which provide functions extraneous to video reproduction will be eliminated from the design. My guess is that such a cable should yield good visual benefits. I'll report back with results once a functional HDMI connector is made. It will be compared to some cheap and a few more expensive HDMI designs, as many as my friends and I can manage. Should be fun!

Of course, any other advice you "Goner video experts would offer is also appreciated. Thank you all!

Also, I'm not a tech-guy, so "KISS!" (Keep It Simple, Stupid!) The level of a budding neophyte videophile should do (i.e., the level of a clever twelve year old! That way, if I get confused I can have my 'clever' twelve year old son figure it out for me!)

Thus, I ask you 'Goners for help. Thanks for all of your anticipated assistance and advice.

HAPPY LISTENING!!

That is pretty much just a DVI cable with adaptor.

Chadnliz said it. It already exists as a DVI cable and HDMI adapters.

If you are talking about fabricating your own cables I would recommend against it. The wire and connection surface in modern computer/video cables is tiny and would be extremely difficult to construct. Just by a quality cable.

HDMI cables are not just DVI cables with a different connector. The construction, geometry and number of wires is different, to my understanding.

Further, the wire gauge used in commercially available HDMI models is around 23 or 25 gauge or so, which poses no problems for anyone with a fine tip soldering iron and steady hands. Leave the worrying to me about that, Timrhu. I make my own cables all the time. I was just hoping someone would pass along the connector pin diagram with explanatory notes. I am SURE that once I get the proper info, I'll make a cable that will likely outperform most conventional designs. There are certain things cable makers don't do (or don't do well, more specifically) because of cost and production constraints. Further, I have some unique design philosophies not represented by the mainstream manufacturers, which should provide a fine comparison to these more conventional designs. Yes, DIYs can be time consuming and laborious, but I am retired, so I have the time to waste.

Thanks for the posts, but I will not be dissuaded so easily on my quest. I look forward to an informed, like-minded individual sharing their experience and knowledge with me, and they can rest assured I will likewise share my findings with them once the cable is made and compared to commercially available stuff. Maybe the commercially available stuff will blow away my efforts. Hasn't happened yet on the audio side when I DIY cables; I see no reason not to try on the video side of things, as well. And if I come up with something good, well, share and share alike is what I say!
