The ultimate VGA to SCART adapter
buttersoft:
I don't think any TV or PVM from about 1990 onwards would be damaged, they way they capture sync means they'll just fail to sync to anything outside their range. But i'm sure it's best to be safe. Some old Arcade monitors and older computer monitors certainly will be damaged, as they're circuitry was only meant to see 15kHz, and they will still work to capture whatever signal is input and damage themselves. They may not fail instantly, but in some cases the damage can be cumulative.
Those wouldn't have SCART sockets of course, but i'm not using SCART and I'm building a couple of your adapters :) I was just trying to find out what they can handle and what uses they might be put to.

I am happy to say I have found two stores selling implementations of this adapter.
One is https://www.arcadexpress.com/es/arcadevga/457-cable-arcade-vga-scart-usb-5v-12v-con-audio.html
This implementation looks almost identical to the original, except the position of the LEDs.
Another one is http://vga-scart-converter-f-15.mozello.es/catalog/params/category/0/item/1443803/
The appearance of the latter is quite different. The switches are more accessible so that the power supply or the aspect ratio of the screen can be changed without having to open the adapter. Another notable difference is that it has a female VGA input and two SCART outputs, one male and one female. The adapter can be connected directly to the TV with the male SCART connector. Alternatively, it can be connected via the female connector using a SCART cable.

Hi gambaman, just wanted to say I got the pickit 3 and a few pics have have been giving this vs a whirl! It all works very nicely. I did modify your original design, I have one version that has RGBS and the LEDs and it fits into a db15hd backshell - same as a regular db9 backshell. It uses an soic version of the pic chip.
I thought it might be nice to make some 15khz detector dongles, sort of thing. But it's not too hard to add a cable or cables in there as well.
I'll upload the modded design in a couple of days when I get back from holidays :)

I'm happy to hear that. Please, upload photos.

Please let me know if the project doesn't share properly, i haven't had to do this before!

can be ordered cheapest from OshPark, but you can also download the gerbers from there and upload to another fab:

I built the only SOIC PIC i have right now into one adapter, but the 3d models of the boards look like this:
It solders directly to the back of a DB15HD male solder plug, and should fit inside any backshell, with room to connect a cable too.
