PostSubject: The SNES multi AV RGB testy....thing!   Fri May 25, 2012 11:27 am

I build rgb systems as a hobby. But I don't own a rgb tv. It's always good to have a way to be sure that my rgb lines are wired to the correct pins of the multi av port. Since I've been hired to build a lot of these machines I decided to make something to make testing rgb easier....

I present....the Drakon SNES / AV famicom multi AV RGB test thingerrrrrrrrrrr mark 1!







It's just an external cxa2075 video encoding circuit. But it's an easy way to test that all my rgb connections are good. It's a cxa2075 ntsc application circuit I made out of spare parts and wired into a snes multi av rgb plug. It encodes the rgb into s-video so I can atleast be sure that all the rgb stuff is wired right. I'd build a case for it but twice encoding the image doesn't look as nice as the s-video internally generated.

Uhm, I'm using it to test that the rgb is wired up properly in the console.
