Topic: Convert composite to VGA

[Hiatus]

Hopefully there are some fellow electronics geeks out there somewhere...

Anyone know how to convert a composite video signal to VGA?

I know there are devices out there that can accomplish this, but does anyone know how to build one from scratch?

I don't like to spend money on stuff I can build myself, lol... I've been searching on the net but everything seems quite complicated...I'm not overly smart with electronics, but I do know quite a bit.

I might just have to give up and buy one eventually... then maybe open it up and see how it's done, .

I saw a wiring diagram recently for VGA to RGB Scart but I cant imagine that youd get composite to VGA as youd only have two wires connecting to a 15 pin plug or socket  :?

If you dont mind me asking, why do you want composite to VGA as composite is the lowest video standard and VGA is much higher  :?

The units are used so you can display composite on a TFT





Description

New Enhanced Model which uses 12v regulated supply so can fit into most CCTV installations. Auto turn on with power loss to default resolutions and refresh rate ideal for LCD Monitors. New Product Released September 2005


That's the only ones i know about

Have you seen one in action Cammy ?

I should imagine it would be a crappy picture wouldnt it  :?

Yes


They are not quite as good as CRT but ok for non critical situations  


Should depend on the video source and the monitor i'd think.

Is this something similar to what you were looking for?

I'm using my computer as my TV, so I don't actually have an actual television. So I just wanted to know if I could hook-up one of my old systems (N64, or SNES) to my monitor to act like a TV... I can't use the TV tuner because of the lag between the controls and the graphics.

So I was thinking that if I hooked up the system directly to the monitor it would solve everything...

I also saw a wiring diagram to convert to RGB... I even have the instructions:

splicing pins 1 and 6, 2 and 7 and 3 and 8 while shorting 4 and 5 as vsence (ground). Each of those pairs in that order are; RED, GREEN and Blue.

But then I need to get from there to composite... which I think involves quite a bit of electronic-type stuff, lol...

The closest I got to figuring this out was this: http://elm-chan.org/works/sc/report.html

But that's an s-video input.
