I tried to get the drivers to be developed as free use supported software Like linux and GNU software , but that did not seem to work too well , because not many people bothered to send any detais back how did they get the system to work for benefir the others.
I have other projects to work with. The main program is the software support for various PC graphics cards, which I am not planning to do lack of time, resources and resource. This project is no longer largely supported because supporting this will take too much time from me too many questions coming all the time. I don't send you any drives throug e-mail and comment will this work on graphics card X on system Y running operating system Z.
Read the documentation and see what it says. If your graphics card is not mentioned in the documentation then I can't help to detemine if it works with this circuit or not. If you get the system work nicely a feedback is wellcome. FAQ Legal Notice. The sync signal combiner has a system to adjust to different sync polarities so that it always makes correct composite sync signals. VGA card uses different sync signal polarities to tell the monitor which resolution is used.
This circuit adjusts to sync signal polarity changes in less than milliseconds, which is faster than setting time of a normal VGA monitor in the display mode change. Building the circuits VGA to TV converter is quite easy to build if you have some experience in building electronic circuits.
The electronics of the circuits can be easily built to a small piece of veroboard and no special circuit board is needed. I used this approach in my prototype. Remember to add powerfeed to the chip U1. It has not been marked to the schematic. The circuit takes less than mA current, so you don't need a large power supply. If your VGA card does not have power ooutput, then check my How to get power from PC to your circuits article for more ideas.
I have built most of adapters I have made to a small circuit board which is designed by me and Aki Suihkonen. You can see as small picture of the PCB in the picture below copper traces viewed from component side : If you want to make this simple one side circuit board then download either the copper sive view or component side view whichever suits your use better.
Component side view of the PCB is very useful if you hare making the circuit using photographic method turn the slide you just printed around and use it as the PC master film for exposure or if you use heat transfer method just print the file to a special meterial which allows transfer of toner to the copper on the PCB using presure and heat.
I have also provided you are zipped Postscript versio of the component side view of the circuit board. When displaying computer graphics on TV screen you will very easily see the limitations of the TV itself and the TV broadcast standards. Anybody who has tried to display computer graphics on a television knows that they look bad. Colors wash out, detail is lost, and the whole thing flickers. And that's the best scenarios. Sometimes the graphics really get distorted. While everyone knows that televisions do bad things to computer graphics, few people are sure exactly what is happening.
