power RGB via HDMI cable

[SushiWarrior Ron]

Hi friends 

not sure if this is the correct place for this. put im looking for a way to carry 18 wires in one cable

23w
24v

and im wondering if i would do that with a HDMI ?

Anyone?

extend the 6 x 3 wires of 3 rgb systems in one cable

Should be possible with something like that.  I'm not sure how long you could go.

How many volts/amps are you going to push through that?  

HDMI isn't designed as a power carrying cable, so the pins / cables aren't designed to carry much.  (The power wire on the cable generally carries 5v 50mA, which ain't much.)

something like this

24v - R - G - B - W - C (24w)

24v - R - G - B - W - C (24w)

24v - R - G - B - W - C (24w)

 

i got a cable that says   with ethernet

So, you're talking about up to 24v 1A per channel.

 

IDK if HDMI will safely push that, you'd have to do some research on the connectors to see if they're rated for that.  If they're not (the pins are very very close together) you could arc across pins and fry stuff.

im going to snipp off the connectors and attach 3x pice 6pins

you never said that you were just using the wires inside.  That makes a big difference:

 

What is the gauge of the wire in your HDMI?

 

You could just use this:

Sorry; I dont know about gauge but here is a picture of the wire inside

the gauge is how thick the copper wire is, not counting the plastic sheath.  

 

That's important to know.

oh ok then I dont know. So if i use 6 pin Pcie connectors the only problem can be that the 3x +24v wires can get hot?

electrical  comes in the from of heat when not being 100% used so thicker wire reduces the heat but also reduce the power by a bit. at some point the wire can heat too much and melt and short out. each gauge wire has a safe limit it can handle. the connector on the wire also has a serten amount that can handle as well so you have to take that in to account too.

 

too thick of wire it reduces the power.
