By adding a power source to the end of the Redstone Wire in Diagram 2 (or on a block
above it, as we will do in the next step), we create what is called a NOT Gate. A NOT Gate
is a type of construction known as a logic gate, which manipulates a Redstone signal and is
something we will learn in the future chapter on Gates.
7. Cover the last block
of the pit (farthest from the wall) with the same type of block that
makes up the rest of the floor. Put a Lever on top of this block. Now cover the second block
of the pit with the same type of block, but with no Lever.
8. Flip the Lever
and the Sticky Piston should pull back and uncover the hole in front of
the Door.
9. Go back through the Door
to the pit in front of it, and dig the pit deeper. Here you have
a few options: place Lava or Cactus at the bottom of the pit to kill intruders with damage,
make a long drop that will kill the intruder (at least 24 blocks down for a TKO), or build an
area at the bottom for the intruders to fall into and just, y'know, hang out. Until you come
to slice them up with your Sword, of course.
10. Go back up
and cover up the Sticky Piston by placing 2 Slabs of any kind on top of
the two blocks it takes up. Don't put one over the spot in front of the door, of course.
11. Wait for a Creeper
to come stand outside your door, flip the Lever, profit.
