This won't let you put in other mechanisms such as locks though but for simple doors with a single switch this is the easiest and it's easy to hide too.
But theres not switch ._.
This one has a button on the outside and a lever on the inside, it's there and labeled, what do you mean there's no switch?

Is it possible for you to build the flipflop and clock elsewhere and just wire it over to your airlock system? Or is there just no feasible place to hide it away at?
Trying to design standardized systems for when I build fortifications and castles and the like. Having a giant JK and and 4 clock as part of that design is just to much....
I was trying to wire up my standard airlock system to a small airlock but was having trouble doing so with the switches being so close together. I broke down and decided to just build my toggle. I could have fit all the wiring on one floor under my outpost but the clock is easier to integrate when it is underneath. The failure rate is acceptable, and almost un-noticeable... at least until notch adds a redstone toggle, oh I hope he adds a toggle.
Thanks to nekizalb, Baezon, and Photon. Used a post by Photon to get the general idea (I've never worked with circuits before) but the 5 clock needed to be attached using nekizalbs method, and working with Baezons 4 clock inspired me to keep trying.

I think I will build a cellular automaton (put my money where my mouth is, so to speak).
I think a Conway sim would be very cool, but 2D automata pose their own problems in Minecraft: How do you view them? If I were on a tall tower or glass floor overlooking a very large field, it might work, but designing 2D cells constrains two dimensions, and if you dig a pit for proper viewing distance, it may even be cramped in the third dimension. Considering the added complexity of 2D automata (as compared to 1D), that would turn out to be a formidable project indeed.
EDIT: Although I have heard concerns about clocks stopping, etc. beyond 300 blocks away, I have not heard anyone discuss the (even worse) possibility of machines reaching invalid states because parts of the machine are unloaded and hence frozen, while others are running normally. Particularly with my synced clock setup, this phenomenon would be disastrous (or would at least produce undefined behavior). Have any tests been done concerning loaded chunk/unloaded chunk boundaries?
Good luck with that. Are you going to build Rule 110?
Wervyn had plans (efficient mergesort NOR array, D-flop, and few logic gates) for compact cells (10x10 I believe) for Conway's Game of Life, but it was ruined by Notch's redstone update. Well, at least, the compactness. Given synced clocks (possibly synchronized by a global clock toggle), it would really work. I think a giant glass platform will be good enough of a viewing platform.
This could be somewhat prevented by turning the whole machine off (turn off the clock) if one were to leave the area. Another solution is to keep each module in 16*16 chunks, so parts wouldn't get cut off. I'm not sure how it would affect the state of the machine, though.
My cellular automaton is at last presentable! Each cell is 4 blocks wide, 11 deep (6 above, 5 below), and 40-ish long. (In hindsight, I probably should have built higher and not so long.) During the day:
At night, in operation:
The most salient feature is the display, which is sort of a "scrolling history" of the cell values. Due to lag in mysterious places, the update is not perfectly simultaneous, but does complete in time for the next clock cycle. Each cell is represented by two columns. I was going to take a picture of the circuit, but we all know that actual MC pics are too hard to read to actually get a picture from. I might post a MCRedstoneSim picture if anyone is actually interested to see the interior.
Here's the save file. Note that in my attempt to keep file size down, I have removed many chunks which Minecraft would prefer kept, so you may experience a lag spike when you start it up as these chunks are regenerated.
I discovered a very nice way of synchronizing the clocks while messing around. It turns out that a single long unbroken stretch of wire, connecting equivalent sections on each clock, will automatically synchronize them, even if the long wire is longer than 15 blocks, since each clock will sync with adjacent clocks. Look at it in the save to see what I mean. There's a passage to the underground wire 12 blocks from the front.

Quote from Urchin »
I made this thing in the previewer. one of you people who know what the hell you're doing tell me if this could be used for anything.
Although the wiring to fit it into an enclosed space might be complicated (it always is), it might work as a 3-entry airlock. The top buttons open the door (RS latch) they are attached to, and the bottom ones work as an override, closing all doors (I would wire all three buttons together into one). The curious part is that each door will only open if the last door opened was on its right. Useful? You tell me.
I made a working (tested in-game) alarm system, i just thought i'd share it, and also ask for ways to improve it.
Blue = trigger
if blue is triggered, the doors will repeatedly open/close, making a large racket that should alert you if you're anywhere close to the actual alarm. the alarm is turned off with the other button, and if the other button is replaced with a lever, you can set the alarm to not trigger. the blue should obviously be a pressure plate when making this in-game.
EDIT: I know these things i'm posting aren't really big fancy logic gates like those flip-flop things or whatever, but i need somewhere to put them.

Yeah giant clocks and display boards and computers are great but the average minecraft player could better use small, simple, practical contraptions for their everyday minecrafting lives. It's just a creative vs survival argument.

I'm pretty bad at this, and the solution may be simple, but if someone could help that would be awesome.
Basically what I'm trying to set up is for there to be a switch inside a building. When this switch is on, a button outside the building can be pressed to open the door to the building. When the switch inside is off, the button outside does nothing.
I've tried a lot of things but most of the time the door is left open when I don't want it to be.
This was about the closest I could get. It does the opposite: the door is open when idle instead of closed.

The more Swiss cheese you have, the more holes you have.
The more holes you have, the less Swiss cheese you have.
Therefore, the more Swiss cheese you have the less Swiss cheese you have.
if you wanted to change that, just remove the NOT gate at the end of it, or add another one.
Or you can position the door so its closed when its recieving power(in the simulator, press the middle mouse button/scroll wheel on the door to rotate it), then when you cut power to it by pressing the button, itll open
Edit: oh wait, then when the switch is off the door will stay open... *tries stuff*

Since I went to the effort(not much but still...), even though Sven beat me to it:
Left is NAND, right is AND, both are suitable for what you want, just note the rotation of the door for the NAND, by making it closed while the door has power, instead of open, you cant just place a torch down to open it from the outside....but yeah it probably will never make any difference

The main reason is because in the first one the powder is not pointing at the door, it follows its current direction only.
Also, since I am into practical usage, I did up a multi-level version of the AND lock, which hides the redstone powder below the ground level(Layer 3 is the ground level, which ive filled with the yellow blocks to show this)
This one has a button on the outside and a lever on the inside, it's there and labeled, what do you mean there's no switch?

You would just have to wire it up suit your structure.

binary number display has been done...however, the door system you use is damn clever, I love it!
You also will not be able to lock a wooden door because all you need to do is walk up to it and hit it to open it.
