So yesterday I was looking at door/gate houses that could open up using a switch, this I was going to add to my huge gate for the castle which I am building in the Factions portal area.
Sadly that video was out of date and due to the recent updates in minecraft that system no longer works. This I only found out after I have spent 4 house trying to fix it and get it to work... sad really.

Today I decided to give it one more try, but everything I found was helplessly way to big, until I found this. It is perfect, will need some adjustments to suit what I have in mind. This layout is crazy confusing though so many things can go wrong especially if someone goes and spams the switch.
