If you’re working with a CGA, EGA, or RGB gaming system this inexpensive board does a great job of converting the signal to VGA so that you can play using a modern display. But what if you have a SCART connector as an output? That’s the situation in which [EverestX] found himself so he hacked in SCART support.
The first step is to source a female SCART connector. He grabbed a coupler off of eBay and cracked it open, yielding two connectors. Now comes the wiring and you may have already noticed that there’s a lot more going on here than the color channels, sync signal, and ground. Technically that’s all you really need to make this happen, but the results will not be good. First off, the sync signal for SCART tends to be rather awful. That’s where the blue breakout board comes into play. [EverestX] used an LM1881 to grab the composite sync (yes, composite sync, not component sync) signal as a feed for the VGA converter. He also added in an audio jack for the sound that is coming through the connector.
