This one below is the smallest I could make it (on a piece of boaard) to fit into a scart socket plug for a converter I was making. I joined up all the ground pins, connected Red, Green, Blue, Left, Right, 8 and 16 for AV and RGB switching etc from the relevant pins on the scart socket at the other end of the cable. Here you can see one I managed to squeeze into a scart plug, using scart pin 8 to supply the power. ![]() ![]() ![]() The one I made below is obviously on too big a piece of board, I was originally going to mount it in a project box along with some other bits and pieces, but ended up not using it in the end, and making a much smaller one to put into a scart plug, I squashed the components by putting the leg from the capacitor and the chip through the same hole etc. You can make it small enough so that it fits in a scart plug. Here’s how to build a Sync Stripper from the popular LM1881, some TVs or Signal Converters (VGA to RGB scalers etc) work better if the Composite Video signal is cleaned up, the video signal is ripped out, leaving the clean Composite Sync signal.Īnd here is a diagram of the board I made, along with a few photo’s.
