This is a simple circuit to connect your VGA graphics card to your TV. The advantage of using RGB over S-Video is superior contrast and clarity. The schematic of this circuit is taken from Tomi Engdahl’s site. The circuit basically XORs together your horizontal and vertical synchronization signals to create a composite sync output, and adjusts output for input polarity. By setting the resolution and timings on your VGA card correctly, it is possible to generate a signal that the TV will accept. This circuit works for both PAL and NTSC signals, just adjust the timings in software accordingly. To see which timings to use, this site has a list. If it doesn’t work, experiment a bit. The resolution should normally be 720×576 for a PAL tv. The refresh rate should be 50 Hz interlaced. Use Powerstrip to set the timings after you’ve set the resolution to 720×576.

I don’t entirely recommend using this option for a VGA cord, because the cable used by the author the CAT5 ethernet cable is not shielded and doesn’t have the same properties as a native VGA cable. But this solution works too, so if you’re in desperate need of a VGA cord and can run the store an get one, you could approach this instructable.

The WITNESSCAM is a self-recording surveillance camera that’s perfect for the home or office. The innovative, ATmega32-based system features a VGA CMOS color camera, a passive-infrared (PIR) movement sensor, and a 1-GB SD card. The aesthetically pleasing prototype looks like an ordinary alarm detector, but when it detects movement, it silently starts recording. You can control the camera an infrared remote. The interactive camera responds with voice prompts, and the circuit can recognize when the box is open.

Now this is a project i always wanted to build, but never had the chance, or the mood. Its kind of complicated, so beginners should approach this project. Thats probably the reason i did not build it myself because when it first came up to me this idea i was still a beginner and did not had enough experience, and even now when i can say i have some experience i still could get into trouble with this project. The authors of this projects explains the problems that he came across and how he solved them. You should expect some pixels looking distort, the project its a work in progress and even in the final form you cant get perfect results. Unfortunately the author fried its panel until the completion of the project by accidentally switching the +12V and +5V lines. So he says it will finish the work on project as soon as he gets a new LCD panel.
