Default Composite-to-VGA

Does anyone know where I can find a schematic for a Composite-To-VGA convertor? I'm wondering if I can build something cheaper than I could buy something like the TV-3000.

Default question to blu_line

This is a off-topic question (sorry), but I don 't want to start a new topic for this.

I have a question for blu_line:
I saw your from holland also just like me and I 'm wondering if you bought your lcd-panel in holland. If so, where did you bought it?

I 'm searching for a second-hand shop where I can buy a Nview panel. (can order one in USA butt shipping cost are way too high $150)

May I ask where you bought it, cause I looked at www.invsol-inc.com (inventory solutions) and they gave me a quote where the shipping-cost where $150. So where did you bought it?

Best regards...Amnesia

blu_line: that site you posted I have seen before, that is for converting VGA into RGB+sync. I want to convert VGA into a single RCA composite video in kinda thing.

I am getting confused now do you want to go from composite to vga or from vgta to composite?

If you want to go from composite to vga Why not look at the TV-1000 This sells for less than $200 US.

You have to first digitalize the composite. Then output it to VGA.

A computer can do this nicely with winTV from Haupauge, but I can see if you don't want to turn your computer on to watch a TV show on a computer monitor.

You have two options buy a composite to VGA that is used for game consoles or make your own.

Go to ePanorama.net for examples on serveral thousands (should I say millions) of circuits.

thanx for the link electro. I'm gonna start sifting through all that info and see what I can find.

and yes haldor, I got it mixed up in my last post. I want to take a composite from say a DVD player and output it to a VGA port. I know I can get a device that will do what I need for around $100, I'm just trying to see if I might be able to build something on my own for cheaper.

Hi JahklaR,

The TVOne VD-660 Cheese box lists for $69. This supports 640 x 480 VGA resolution max, and is about the lowest cost solution I know of.

The model I meant to recommend in my previous post is the AVT-3340. This supports 1024 x 768 XGA resolution (and lower) and lists for $99.

All of these models have both composite and s-video inputs. Here is a good source for info and pricing on up converters: http://www.avtoolbox.com/video-to-vga.htm

Take a good look at what doing the up-conversion is going to take. The PCB design is very crucial and the single quantity price for the up-converter chip is pretty high. I seriously doubt if you can DIY something like this for less than $100.

Phil
