I am looking to make a system to keep people from coming to my house without permission from mffs so i am using warded stone in the entry room and theres 1 2 by 1 place for people to enter my house. I have a projector creating a force field blocking the 2 by 1 space and a inactive defence station that will kill anyone that does not have permission in a 10 by 10 radius. I want to be able to push a button and be able to activate the mfs defence station 2 see if i have perms and if i don't die 10 seconds later (or however amount of time you see fit) the force field blocking the 2 by 1 place will shut off then i need the system to shut off i'm stumped i tried using mfr rednet but i get lost with all the programs. Any ideas?
