I am working on a map and update when ever I can. I was working on this when 14w26b came out and something really interesting happened. (I am basing all of this off the pictures) When the lever is turned switched on, the repeater I am pointing at in the first image will start flashing on and off. I tried to recreate it in another world but it wouldn't work so i'm assuming it might have something to do with the direction it is facing.
