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!!

I guess you told us! :)

How do you go from "I'm not a tech guy" to "I have some unique design philosophies"?

I meant no disrespect but your original post lead me to believe you were a novice DIYer

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!)

I also build my own cables but my eyesight and hands aren't as steady as yours because I wouldn't attempt those cables. Best of luck with the project.

Thanks Gents!

'Goners are the BEST! Hey, you all may be right and it might be useless to DIY this, but why not try? And if it kicks ass, I'll share the design.

No, I'm not a techie guy. No EE knowledge, no nothing. Just what I can pick up from you folks who are the real experts. I do know audio insofar as reducing distortions through sound engineering (vibration absorption, shielding, etc. No rocket science, I can assure you!) are concerned. But video? I'm lost, plain and simple. Completely ignorant. Dumber than a box of rocks, as they say. But I can learn, and I want to.

Thanks Ronnjay! I will definitely check that out. Looks great.

I could be wrong about differences between DVI and HDMI, but all that extra wire and signal for audio just makes me think there is a better way. I'll try and use only high grade wires, connectors, and shield the snot out of these puppies, grounding same and spacing the foil shield at least a half an inch away from the conductors using cotton batting to roll up the wires in for the spacing. That's it. Nothing brilliant. Just great parts and excellent shielding, all with room for the signals to breathe. That's all. Nothing magic or Einsteinian about it. No secret plans for world video cableing domination. Honest.

So yes, I really am a video novice, just trying to apply what I learned in audio. Maybe they don't correspond well. I hope I can come up with a better mousetrap, but we'll see. I might just fail miserably and end up buying what you 'Goners say is the best HDMI cable for the money. That would be fine, too. But I just want to give this a try and see if it works. That's all.

Thanks for all your posts, guys. They really are appreciated!

HAPPY LISTENING!
