Ruby Redstone

I think it would be cool if this new type of ore will be able to be turned into armor and gear. It would be called Ruby, or Ruby Redstone, because it would emit a redstone signal. Example: If you are wearing a Ruby Chestplate, and you go near an iron door, it will open the door when within range. Also, If you were near a lever and if you had a ruby sword, the lever would activate itself. You could also make Ruby keys, where you pair the key with the iron door, trapdoor, chest, or even a secret room, to make it that when you come very close with that key it will activate the redstone.
