| Tapping off the power supply for a LCD |

Very cool, I do enjoy that build! Now I have something to think about. Thanks for you help guys. |

So let me ask you about the monitor that you used. Did it take a regular power cable that looks like one that you use for the PC or did it take a power brick? I re-read your build thread and although I cannot find it now, I thought you had an issue with AC DC power for some reason with the monitor. On a side not, man I love those buttons. |

I think I answered my own question here. I took a look at a few monitors that I have and the one with the power brick outputs 12Vdc --- 5A. That is what the power supply is going to be providing isn't it? I see that the positive is on the "inside" and the negative is on the "outside". That would mean that I would need to connect the +12v to the "inside" and the ground to the "outside", correct? If so this is totally doable. I will have to go to a 19" monitor if I don't want to spend money on it since I have one here but it's cool. Kind of excited that I learned this new technique! |

My monitor was actually part of an all-in-one gateway profile 5 pc so it was powered from the motherboard through an LVDS connection (i didn't know of such a thing until the hours of research I conducted to learn a work around...) I found a distributor from china that makes an lcd inverter board that matches almost any model of screen you have and is powered by a 4 or 5mm (can't remember) dc power connection that provides 12v to the board; it outputs a VGA connection. I had an old car charger that was the same size so i chopped the end off and soldered the leads from the RCA phone cable to this from the barrier strip. Bottom line, I think you're on the right track given the fact that yours has an external power supply so you just trace down your leads and patch into your ATX. Good luck! |

I just wanted to let you guys know what I ended up doing. I also hate searching and finding threads with no resolutions on them, lol. I was able to successfully hook up a 19" LCD that uses a power brick to the power supply. It expected 12v DC so I was able to hook it up like NS did in his build. There was a + and a - for the cord, so you just hooked it up accordingly to the power supply. This was just a test as I am planning on building a somewhat smaller project and wanted to used a smaller LCD. Next step, using a LCD from a notebook. After some searching on google I came across an eBay seller who sells a nice little kit that will let you send a VGA signal to a notebook LCD. I have a bunch of old notebooks that work but are not fast enough for what I was planning on doing. I ended up taking the LCD screen out of the notebook, decased it and disconnected everything from it. Cleaned it up a little bit and waited for the parts to come in. It takes 12v DC so using the same cable that I rigged up earlier, I hooked it up to the power on the kit and the VGA to the kit and viola, I have a nice 15" screen that is thin and very very light for my build. With the testing done, I can now start designing and getting the project from my mind to reality! I just wanted to thank everyone who responded for their ideas. It really did help a lot! |
