The ultimate VGA to SCART adapter

I have uploaded the model here - https://anonfiles.com/W3EaXel0z2/DB9_double_complete_tiny_v5_stl
The caps and the resistors are all 1206 SMD packages. The caps are 10nF and 100nF - and are optional, though recommended, i think. (The cap you linked to was not SMD/surface-mount and was 2.2nF)
Make SURE you have a device that can program the PIC first, like a PicKit 3 or something.

I see that you back in 07/28/2020 improved the resolution switching.
Is there any way to improve it even further?
Seeing as some games in Retroarch are struggling when switching from 240p to 480i.

Sorry, I have just read your post. Not sure what you mean. A resolution switch should just deactivate the output for a pair of frames.

I have decided to make a small batch of the passthrough protection dongles for sale. I'll put up a separate post with more info shortly.
Gambaman, i'd love to talk to you about compiling your code for myself - my last attempt at this went pear-shaped and it'd be nice to figure out what I'm doing wrong :)
EDIT: righto, my sale thread was moved to the correct place by Scott :)

The link is no longer working.
But would you be willing to add your dongle to Hackaday with instructions? :notworthy:

I have split the body and the lid, and added a version of the lid that has holes so you don't have to drill. You may still need to chase them with a drillbit.

And no, sorry, i am not keen to write up more details instructions - too busy with the kids. Everything you need is in this thread, and the little PCB is stencilled with part values. Passive SMDs are all 1206 sized, though 0805 will fit. I might be able to answer specific questions, if you need.
I will say again though, make sure you have the means to program the PIC before anything else :)
