MINECRAFT CHALLENGE: Redstone WITH NO REPEATERS!

I was thinking just the other day it has been absolutely ages since i’ve taken on any forms of redstone challenges lately so i was doing some thinking and i was also rooting through some of your suggestions and i saw this one popping up the challenge of not being able to

Place one of these guys the repeater oh boy i mean i rely on these things pretty heavily i mean just look around this place how many of these redstone contraptions do you think don’t have any repeaters in them i’m imagining it’s probably in the single digits i can’t

Think of the last time i built a redstone contraption without a repeater and just to make my life a tiny bit more difficult i’m also not allowed to use comparators and observers as repeaters so i can use them for their normal functions but i can’t use them as a

Replacement for repeaters because that would be really boring wouldn’t it so let’s jump right out of the gate here with a fairly tricky one which is the triple piston extender normally i start off with the double but triple triple feels like the way to go so i’m thinking

If i put redstone torches next to all of these things and then have redstone there and there okay so we’re kind of gonna have to alternate between these things so that we can actually power all of these pistons yeah yeah okay and then we can run the redstone up and off like this

For these ones and down and across like this for the ones on the bottom okay my original idea was a total fail but i think okay so there is the triple pizza extension and then they all extend in totally the wrong order so then we need to create some form of pulse extender

To actually make it so that these things stay extended for long enough so we need to take i’m guessing so if we run this out from here and then we’re going to need to run this through a serious quantity of of torches i mean we could we could kind of use a hopper

System maybe that actually might be a good idea yeah so inside this hopper right here i’ve got 16 items when i flick this lever you can see that those 16 items gradually make their way into this hopper now we probably don’t actually need 16 items in fact we probably need something along

The lines of maybe five or six but then when we flick this lever okay that’s like a mega pulse extender that’s super useful yes i think i might be onto something finally i’ve managed to kind of get the hang of this thing as

You can see we’ve got a bit of a mess of circuit so far but when we flip this lever down on the bottom we get the full triple extension and then we get this retraction pattern which means now all we have to do is retract this block so if we put a block

Out the front of this thing all we have to do is do the first block retraction so this retraction then we need to retract this piston back to here and then we need to retract this piston once again once it’s back in this location so it’s a simple

Double piston extender and hopefully i should be able to do that using observers and sticky pistons to create monostables now i’m just gonna go out there and say it this is probably one of the fastest last block retractions i’ve ever created and it’s done entirely with redstone torches so with that final

Piece of the puzzle that should be our full triple piston extender working properly so there we go and there is the retraction there is the extension and there is the retraction maybe not the fastest but that last bit is just rapid that’s so so quick okay that’s thing number one done

Now this one should be a fairly simple one but i just wanted to see if i could actually do it so let’s just fix up any things that have gone wrong right here and i think we should be good to go so if i power this thing i’m very

Curious to see what happens here a mess a mess is what happens but that mess has actually fixed itself which is even more peculiar and this thing actually functions there we go there is a flush with the wall piston door built without any repeaters okay i’m getting the hang of this okay

Okay those ones are relatively easy what about a working color combination lock that you can have multiple modules off oh that’s gonna be tough okay you won’t believe this one but i think i might have done it and i’ve done it in a fairly smart fashion look at that three blocks wide

No repeaters that definitely looks like it would work so for our combination to be correct we need both of these windows to be showing the fuchsia color that color back there so let’s just go on through okay so there’s green okay there it is and then when we hit

This button right here we should see redstone lamp turns on nice so these things actually function pretty nicely and pretty fast as well i mean did you see that and to top it all off with this behind me you get 64 possible combinations which isn’t exactly groundbreaking but if you were

To build another one then you’d get 64 times eight which would be around about 480 that’s a very rough approximation and then if you were to add another module then your times 480 by eight so that would be what around about four thousand maybe yes i think potentially you know my my

Quickfire maths isn’t particularly good but you get the idea these combinations add up quickly anyway that’s enough of that maths nonsense now it’s time to get our hands on a real challenge and it is gonna be a bit of a tough one three by three piston door i feel like

We can do it if we just have this and then this setup here i mean double extension i know single extension retraction move out the way double extension retraction and then on the opposite end extension extension extension how hard can it be he says confidently

Okay the good news is is that i’ve just come up with this little gem of a redstone circuit which is our double piston extender so that’s all good and then if we wanted to do just a single extension can we do something along the lines of this hmm

I suppose you can just power it from the other side so that shouldn’t be a problem i don’t mean to blow my own trumpet but things are going pretty well so far i mean my normal 3×3 piston doors don’t tend to work this quickly [Laughter] well to say i’m chuffed is an

Understatement please tell me this works if this works the entire system will be so so fast so we’ve got okay so that’s just retracted the blocks and then no would you look at that there’s no messing around going on there that has gone horribly successfully

Brilliant okay so now we just have to do all of the blocks going around the outside which for anyone that’s built a three by three piston door will know is the easiest part of the process and that will be this thing all completed i can’t believe that not only have we built a

3×3 piston door that actually works but we’ve built a 3×3 piston door that is actually in sync which is i mean for those of you who have watched any of my previous challenge videos that’s very impressive generally speaking if we build a piston door in one of the challenge videos it

It is just disgusting to watch you get blocks retracting in weird orders for example it will go like and it will all be very very slow this one is real fast and actually quite nice looking if it wasn’t so big i’d probably consider building it in my base but i’m

Sure i’m sure at least some of you will be able to compact it down why not why not let’s go for it 4×4 piston door let’s do this as i’m getting the hang of this life is getting a lot easier so here is the double piston extender circuit we just need

This redstone torch here and that will do the trick so this should function now if we hit this button there we go and then on this side we have got another circuit which is just going to be our single retraction so that will allow us to do the double block retraction i actually

Think that we could breeze through this obviously that was quite optimistic i don’t want to stay words like that because 4×4 doors are difficult or the best of times let alone when you can’t use repeaters but i think okay there’s a chance that we’re coming close

So if we have okay we need to place an item inside this dropper right here so on the opposite edge of this we should get something interesting happen so we should see these blocks retract and then these pistons retract those blocks out of the way

Yes and then all we have to do is we have to run the output from this which kind of cycles around here into the input of the double piston extender which we can probably do a little bit like that now this is going to be a tiny bit rough around the edges

But i think that should maybe do the trick oh that’s the input to the double piston extender okay let’s not do that uh so that runs out round there and out round here so we need to run redstone torch out from the side of this thing

And then we need to run it across like this and into the side of this block and that should as i say just about do it so if we place in these blocks that should connect all of those up and then if we flick our lever we should see a full retraction so

That’s going to extend those blocks whoa yes oh my word because i really enjoy this sort of thing i’m trying my best to keep the circuitry as compact as possible so you can see that we are working within what a six block space yeah six blocks

And i’m trying to stay up against this edge right here but i don’t know if it’s working okay so there is all of the opening circuitry closing right all we have to do is fire those pistons in between those two piston pulses and it could be as simple as just

Wiring that in let’s see that was actually too fast was it yeah it was too fast um okay that’s not the problem that i expected what can we do about that maybe maybe add in oh this is gonna be difficult how how do i fix that i think finally we

Might have actually got there after a lot of redevelopments and a ton of wiring changes let’s give this a go so if we place the blocks in this door here you can see there is the opening all very nice and then yes there it is okay so that is one half

Obviously i’ll copy and paste the other half over and we’ll have ourselves a fully functioning 4×4 piston door with no repeaters and i gotta say in its full and finished form this thing looks pretty monstrous doesn’t it what a machine one absolute machine but i think that just about wraps everything

Up for today no repeaters redstone episode i hope that you’ve enjoyed it if you have please share that like button and if you really loved it then make sure to subscribe but thanks for watching guys this has been mumbo and i’m out i’ll see you later
