Minecraft 1.7.2 Hidden Piston Doors and XOR Gates

EDIT: XOR Gate tutorial up here http://www.youtube.com/watch?v=jRJrWLEYfbE

This video shows the redstone wiring for a hidden piston door as of Minecraft version 1.7.2. It also shows how to make a XOR gate to activate/deactivate a door from both inside and outside with switches, and briefly explains how they work, and what they do.

Hidden Piston Doors:
The basic concept with a hidden piston door is that two sets of pistons, with a short time delay between them, will push blocks into place to form a facade, and when deactivated will retract to form a smooth entry way.

I show two doors. First, an example 2x2 piston door, using six sticky pistons, six or so redstone repeaters and a reasonably small amount of redstone wiring. It's not perfectly hidden because I was working in a cramped space, but it shows all necessary wiring, and I discuss the timing of the signals you need in order to properly retract the door.
The second door is a 2x1 side door in the side of my fortress. The wiring is mostly on the two floors above it, and it includes a XOR Gate so that it can be opened and closed from both inside and outside. The wiring is fully hidden from view unless you go into the maintenance room I set up, and is comprehensively explained.

XOR Gates:
XOR Gates are a logical gate structure you can easily build with redstone. They take two input redstone wires and conform them to a single output. What's important is that an XOR Gate is an "Exclusive-Or Gate". As such, it ONLY outputs an on output signal if the two input wires have different signals. This allows you to toggle either state (on or off) of a circuit from multiple switches! In theory, you can build XOR Gates connecting to XOR Gates such that you can control a single door from an infinite number of switches with perfect accuracy and no bugs. I explain them in some detail later in the video, and provide an easy to understand example. My main use of them is to be able to close iron or piston doors after I've passed through them, without the use of buttons (timed doors are annoying, especially with lag).

I hope that this is useful to anyone making hidden piston doors or multiple switch doors. Enjoy!

I have a problem, i got the piston door workin. the only problem i been having is, once i click the switch outside, the door close up. Then i enter in another way to click on the switch on the other side. I click the switch on the other side in order to open up but nothing happen. Is there any way to make it work? I been lookin for a way to do so and I found one way by myself but itz still a mile stone step. any tips?

@acelancer Check out my video on XOR Gates. You use them to make two switches control one door. The current one is a bit dark, so I might make a new version. It should help, though!

I need help, Im trying to make a hidden entrance and I need to know how you can pull a lever outside to open and inside to close? Please help

[LewinArador]

@Cotif11 The wires that the levers activate have to meet up in an XOR Gate, which then conforms them to a single output. I've already got an XOR Gate tutorial up, although it is too dark.

good tutorial

but can you, make a tutorial in how to build it with the XOR gate plz?

i´m a total noob at redstone and i didint understand what should i do to make the XOR gate

[LewinArador]

@Gover14 Sure, I'll do a tutorial tomorrow some time. I'll try to get the colour working properly next time too.

Dude UR PRO!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!

This dude sounds like Fenris from Dragon Age 2!

you showed it out for us,now is not a secret anymore.

@acelancer What I usually do is where one of the redstone wire between the outside switch and where the redstone actually controls it. and so at one of those wires i dig a hole down, place the redstone and put a sticky piston with stone (or whatever block) that will push down and stop the connection. If you cant understand with this, you can message me. It is very compact and doesn't take a whole lot of knowledge of redstone.

@LewinArador  Thanks, it did solve my problem in a whole another way.

@LewinArador oh ok, thank you

but..... will it blend?
