Ok- we all know redstone creation can be extremely difficult to master. There are somethings that no one still has any clue as to how to make out of redstone. Some of us are better at redstone than others- it's a fact. So, what's the hardest thing you know how to make out of redstone? I used to know how to make a semi-timer like thing. I forgot how to make it, but I still know how to build a working drawbridge where you fall into a deep hole in the middle. So, as I asked before, what's the hardest thing you know how to build with redstone?
