How to Create the Most Compact 2x2 Hidden Piston Door in Under 50 Seconds!

Every once in a while, Minecrafters want to create a simple hidden piston door to secretly hide all their valuable items. Now, it's possible with only 18 redstone, 2 repeaters, 12 sticky pistons, and ONLY 20 blocks of any kind!

My personal record for building this is 35 seconds! Think you can beat that?

Well, we had better find out how to build it first. :)

Place Down 12 Sticky Pistons

Make sure to lay them out as shown in the picture below, 2 blocks apart.

Place 2 Blocks Inside Each of the Pistons

Put them inside the pistons so you can't see any green spots from the sticky pistons.

Place 12 Blocks Over the Top

Only make ONE layer of blocks to cover everything.

Place 2 Blocks (4 Total) on the Side of the Pistons

Do not place the blocks on the lower pistons; we will be using something different for that space.

Place 1 Block Closest to the Entrance

Make sure to put it where it is in the picture. Do the exact same on the other side.

Lay the Redstone

Put redstone where you placed the last block and also the 2 blocks on the side of the piston. And put redstone on the ground, as shown in the picture. I apologize if the picture is too dark.

Set Repeaters

Set the repeaters facing outward 2 blocks from each other with a 0.3 second delay. You have to make sure that their closer to the entrance than the exit. Refer to the picture for help. The repeaters will help make the pistons push towards the center, then make all the blocks go 1 more forward to be invisible!

You can set the repeaters to a 0.4 second delay if the bottom two pistons don't go back.

Connect the Redstone to Repeaters

Connect the redstone to both of the repeaters and put 4 redstone in the middle, like in the picture.

Your almost done! Now, just connect the redstone to both of the repeaters on both sides, and set 4 more redstone pieces in the middle to make a 2x2 shape.

Now Just Add a Lever! (But in the Right Spot)

Make sure to put the lever somehow connecting to one of the 4 redstone in the middle.

Previous SlideNext Slide

And as you can see, it will not work correct if the lever is connected to something other then one of the four redstone in the middle.

Now Just Make It Look Better!

See, you can't even see it! Guess where the lever is?

Pretty small, right?

Hope You Enjoyed!
