Leds but where to plug-in RCA???
 
Hey, I was reading this mod in ModGod.com and they show how to make your own plug-in-able leds that use a RCA plug.
Custom Leds
But Where is there some RCA plugs inside a computer?
I have never seen any on a motherboard... mayber there is an adapter...
I know some sound cards come with RCA, but that is for audio...

Yeah, RCA jacks are in real short supply inside a computer.....dunno what he was planning on hooking it to, but he must've had a reason....

I figure he probably used the RCA connections for power distribution. IE, somewhere there's a board with a bunch of RCA sockets on it and a molex connector at the end for powering LEDs.

I did some searching and couldn't find anything yet. He must make the board himself.
Do you think there is something else that would work instead of and RCA jack.
Like one of those 3-pin connectors that fans have?

He has to be powering them from his own board.
1 molex will have the ability to power about 200 LED's, they only need about 200mA and about 1.5V each. For that I would probably use DC power sockets, not with the nylon outside, instead of RCA's.

I wouldn't present a typical LED with 200mA, as it's rather more than many LEDs are rated to handle. Some of the smaller LEDs get unhappy with anything over 50mA.

Different LEDs need different voltages. For example, red LEDs will often work around the 1.8V mark. Blue and white LEDs usually require more - sometimes as high as 3V.

Luxeons are the special case, as they tend to want ~4V, and several hundred mA to over an amp, depending on the model.
