Title: Custom A/V cable?
Post by: MNKyDeth on July 03, 2015, 07:12:32 PM

I am making my own cables for the Component and RGB chips from Turbokon.

I am however am unaware (just not sure) of some things.

The regular 5 pin connector on the Duo has video, two audio, +5v and a ground pin. I am unaware if I need to run the +5v and ground over the connector (8 pin mini-din) to the 8pin mini-din to component cable I am making.

I bought a premade component cable that has audio and video connectors. I cut off one end of the cable and soldered the ends into connectors I can unplug from a little wire harness.
Meh pics...

I included a ground on the audio cable part of the cable. But did not hook up the ground to the wire mesh on the video part of the cable. But I am still a bit unaware of where the +5 volt would go on these cables. I don't want to power up my Duo yet in case I have something wrong. I only have the component piece pretty much done and if it works I will finish up the RGB mod and cable.

Well, I guess while I am at it... I am posting another pic of the two mod chips. I used some hot glue to kind of put them together. Instead of using double sided tape I plan on using velcro on the underside of the chips so I can remove them whenever if needed. The way I have the boards wired up I believe will be ok. The only real question I have on this is will I be getting interference from either chip? Should I wire all the wires into a switch to change between the chips?

I am only asking to double check my setup and to make sure I am not going to mess something up.

the 5 volt isn't needed unless you are using RGB. if you're using component you can just ignore it and not hook it up to anything.

Ok, cool, thanks for the reassurance. So I do need the 5v on the RGB cable though as that will be 8pin mini din to scart to a framemeister.

I will have the component part of the system done in a couple of hours from now. The RGB part I need a few more connectors for the cable I see and then I just need to buy the framemeister and then I believe I am officially done.

Then I can start putting my money toward being a collectard.
