Super Secret Door in Minecraft!
DESCRIPTION
Are you always the one gathering materials? Are your valuables mysteriously disappearing while your friends are getting cool things, made of that same material? Worry no more! I made this project because I am very interested in redstone. Also when playing with friends I am kind of forced to make secret things for my valuables because we’re all lazy and steal each other's stuff.
4 repeaters, 8 redstone dust (or more depending on where your trigger is), 12 pistons, 1 redstone torch, 1 stack of blocks, redstone trigger
Build a 7x3x1 wall out of a block of choice
Dig out 4 blocks one block away from the edge, as shown
Place 4 pistons one block away from the hole as shown
Place 2 more pistons on the far side of the previous ones, and make them face the hole
Copy this design to the other side
Place 2 blocks on the end of each of the previous pistons These will usually be the same block the door is made of
Put blocks on top of all the pistons and also in the gap
Place redstone over the blocks over the gap, and on the edges of our platform
Place repeaters facing out connecting the redstone, the ones in the back on a 2-tick delay
Place 2 blocks out and one on top from the gap section
Place a redstone torch on the previous block you placed, IT IS VERY IMPORTANT THAT IT IS ON THE SIDE OF THE BLOCK
Place blocks going from the torch to the output, I’m putting it here for convenience's sake
Place all of your remaining redstone dust on the rest of the blocks
Place a lever on the block the redstone dust is powering
Pull the lever and voila!
