I made a Minecraft security computer in 1 block

This one’s for all the nerds out there i’ve been playing around with the immersive portals mod once again because let’s face it it’s the best modification in the world and i’ve come up with something that i’ve always wanted to be able to do in minecraft so i’ve created

A one by one portal right here which is scaling down this 16 by 16 portal so this this is actually a portal this is this is a portal you can see look i i’ve i’m right there it’s a functional portal that would have been painful i think but

The really cool thing about these portals is i can actually use the things on the other side of the portal i’m clicking on these tiny little buttons so what i wanted to do is turn this little one by one area into a pin code so we enter our pin number into

This little button display panel here the numbers will pop up on the screen and when the numbers are correct this little door will open and to be frankly honest i still have absolutely no idea how i’m going to do this so this should be interesting first things first the

Number displays i need to make it so that we can have various different numbers being displayed onto these things right here and yeah i think i have a good idea and now that i’m placing in the wiring i’m starting to realize that this could be this could be a little bit more

Complicated than i was expecting so what we’re essentially creating here is a seven segment display so you’ve got one segment here one segment there one segment there that’s three segments and then you’ve got the four segments in these areas here and using a combination of these segments we can

Create any number that we want using this display if you imagine any form of digital display or calculator they tend to have seven segment displays to display their numbers so at the back here i’ve created seven redstone lines that correspond to the seven different segments and all we have to do to

Display the numbers is power the correct segments 30 minutes of head scratching later i’ve realized that this this method here is completely impossible but something like this has much higher likelihood of working because now i can actually power the three inner lines as well as the four outer lines as well

Independently making use of redstone torches with the original setup that wasn’t going to work now the next problem that i’m going to run into is these systems are going to be directly next to one another there’s not going to be any space in between them so i need

To make sure that i build them so that they don’t connect to one another ruining each other i did warn you this video was for nerds so when we have these things next to each other thanks to these blocks these two lines won’t connect and thanks to these blocks

These two lines won’t connect so that should be everything all sorted now i just need to connect the redstone lines up into the seven segment display which shouldn’t be too difficult and now i just need to code in all of the numbers and this is done by blanking out parts

Of the redstone which will shut off the line which gives us our number so for example to create a six all i have to do is blank out that redstone line right there and there is our six and to create a seven i just have to blank out the

Bottom ones the two right ones and then the middle one and that should do it and each column corresponds to a different number i have no clue if i’m explaining this at all but to the seven people who are still left watching i hope you’re enjoying yourselves

Because i know i certainly am i mean come on now how cool does this look how cool does this look i absolutely love redstone contraptions that look like they have no space inside of them so at the minute we are displaying number three seven five but if i pop

Down to the bottom here and start flicking these levers we can go to three seven one i can change the seven you can change that to something else let’s chuck that to what’s that three five one all of them are working independently of one another all of them

Can receive inputs this is already a pretty cool redstone contraption but now we need to hook these things up into this little button panel down at the bottom here and i have now realized this is the least secure pin number in the world because the pin number is

Displayed to anyone who is in the room with you but still you know it’s cool oh yeah it got so caught up in the building of the redstone contraption i forgot that i’d be able to see it on this little panel this is the best thing ever

This is the best thing ever right button panel how on earth are we going to do a button panel so i think the obvious choice here and it might not be so obvious to build is to make a red coder so that means that each one of these buttons right

Here will have a different redstone signal strength attached to it that we can then run it into a decoder which now that i’m looking at it is going to be really oh we really don’t have much space here this is this is going to be tight i

Don’t actually know if we’re going to be able to do this you know a decent amount of head scratching later i decided i wouldn’t do a regular button panel because that would be complicated so instead i’m doing this type of button panel which is still going to be

Complicated but not quite as complicated and now i’m going to try my best to explain it which is going to make it sound really complicated so this is our button selector panel it goes from one through to nine and then zero zero is at the end right here currently i have

Number one powered which means that these should be outputting a signal strength of one number one corresponds to a signal strength of one so when we have a signal strength of one being outputted because number one is selected on the button selector panel then that will power number one

On our little number displays which as you can see is working perfectly if we would select number four on the button selector panel then we will get a signal strength of four being outputted which would then select the fourth module of our seven segment display which would

Then display a four on the screen now all this green circuitry is doing is making sure that all of these signal strengths match up correctly because if these weren’t here then they would all have different signal strengths and different numbers on the selector panels would correspond to different numbers on

The displays i think that made sense it probably didn’t but i feel like it did so let’s move on the next piece of the puzzle is to create a red coder because when you’re dealing with signal strength obviously up to the point where it’s not powered all of the other outputs are

Powered and that isn’t particularly useful we want to get a singular output so we’re going to go from this to this that is a lot more useful and i think we can all agree that now that we have all of them in place it looks incredibly

Cool i mean look at this thing as a redstone contraption it looks like a little computer so next up as i begin to make my way through the redstone dictionary we’re going to be building an rs nor latch array that is going to be converting the pulses from the button presses into

Consistent signals what are they called solid signals signals that stick around forever persistent let’s go with persistent now an rs array really does sound complicated but in reality it’s really quite simple if you’ve ever built a button selected a panel before where you only want one output at any given

Time you will have constructed one and if you’ve never built something like that then you definitely should give it a while because it’s a really fun redstone project to work on oh my goodness i am the luckiest person on planet earth this has all come together absolutely perfectly it fits in

Perfectly this first one should actually be working now let’s see does it actually function i’m kind of nervous that definitely wasn’t an eight was it i made a noise it made a noise as if it should be working but it’s not working and that is simply because i’ve changed the side

Where i’m running the input from so i just need to flip all of these repeaters around which should now be done and we should be getting something through the display it’s still eight was the last one that i pressed in eight no this is flipped it’s just a different

Way around or i expected we need to have we need to have all of the redstone torches on apart from the one that we want selected and that is going to be really difficult to do with the amount of space that we have no no i will not be defeated here i might

Be defeated here this is ridiculous i’m going invisible i’m fading out of the video after enormous physical pain i came up with this solution and it didn’t work but after significantly more pain and frustration and gradually fading out of existence i came up with this system right here making use of observers and

Just all sorts of weirdness but it works this thing actually works and now we are finally getting numbers being displayed on the board that correspond to button presses i mean how cool is this that’s not good thankfully there was just too many items in the hopper it’s absolutely fine panic

Over because i can promise you there was panic this might just be the most satisfying thing i’ve ever made just look i’m i’m changing things on a tiny panel i’ve got a tiny panel in minecraft right let’s quickly connect up all the other numbers oh yeah

Oh yeah that’s the good stuff that right there that is a stunner but you see there is a slight problem with it which is when we hit any number on the number pad it changes all of the numbers in our pin code and that is not very secure that’s

Pretty pants to be honest with you so we need to create a system that will stagger them now i’m really hoping that something like this should do the trick i mean it will be ridiculously simple if it does work okay it will be so impressively simple

But we could be on to a winner here yeah of course it didn’t work of course it’s not that simple right back to the drawing board a little bit pain frustration you know the drone by now but i’m hoping my days of pain should be over thanks to this piston feed tape

Okay so that has just picked up that one and activated that one over there oh and now it’s broken i did not expect to struggle with this bit i must admit i think my brain’s a bit frazzled from constructing this monstrosity but actually it wasn’t you see the first

Idea that i came up with you know the one that i said was ridiculously simple turns out was actually the correct idea i just executed it slightly incorrectly but now that i have rewired it and done it properly it’s working perfectly and it is ridiculously simple i’m sorry i

Doubted your brain so with that circuit now in place we should be able to independently change the numbers so for example we press this one just that one changes then it should be the second one oh my goodness this is exciting this is very very exciting indeed and then it should

Loop back to the beginning again it works it works this is cool i keep doing it on the big one when really i should be doing it on the tiny one i mean how cool is this ah warmth in my chest feeling warmth in my chest right now oh yeah the finishing

Touches are going in now and it just keeps getting cooler and cooler by the minute but you may be wondering what this little bar of blocks is well that is going to be the correct code indicator not only do i want our door to open but i also want something to be

Signified on the actual number panel itself and i think i have just about enough space to make something work here just about enough space so currently our lever is powered which means that the red blocks are up but if i flick this lever everything drops down and that bar goes to green

I mean it doesn’t have to be much more complicated than that does it there’s just one final thing we have to do arguably the most important thing that we have to do and that is program in the correct combination now i was going to do something stupid like do it as one

Two three but i’m sure all of you would have called me an idiot for it so instead i’m going to do something equally as memorable but not as predictable which is the number of days in a year which everyone knows is 356. and with that it’s now ready to go so

Here we have our little screen next to our incredibly secure door and if i start smashing numbers into this thing you can see that we need to get the correct number to actually get inside if i put in say for example 467 everything stays red and our door stays

Completely closed however if i type in the correct combination which is 356 so there is the three there is our five and then here is our six you can see that the green bar slides across we get a nice little sound and our door opens up giving us access to

All of our valuable items now once we’re done with this place i’ve actually added a really handy little feature into our secure system which allows us to reset the code so that nobody can see what it actually is we don’t have to worry about scrambling it ourselves everything is

Just wiped out it’s cleared off and obviously our door closes back up i mean is this not one of the coolest things in the world but this is this is seriously awesome it’s like the least vanilla minecraft thing in the world but i still really want it in vanilla

Minecraft i i could play with this thing all day long and i’m gonna be totally honest with you i really am quite proud of myself when it comes to the redstone behind this thing i mean it is just it is a pure redstone logic mess but like a beautiful mess

I mean that in a nice way this thing is awesome so we have it ladies and gents that is my little one by one security system pin code whatever you want to call it i’m chuffed to bits with this thing i hope you chuffed to

Bits with it as well and i’ll catch you in the next video see
