If someone would like to do it I will share the things I've reengineered.
Hi fK1G6HBzdnOY,
Well, right now I will not since my BS3 is working nicely so far. But I know it will eventually fail again someday and then, I hope I'll find you!
I guess it will not be as simple as just connecting three wires to the third input and it will need some electronics to select that input right?
But hey, it opens new doors! Thank you!
