Howdy partners welcome to another CMB minecraft tutorial today I’m going to be showing you how to modify our combination lock into a nine digit version instead of four I had probably about 20 questions or so on this I thought I’d cover it as I think it’s worthwhile I used in building the Batcave and it’s just a little bit cooler I think to have nine digits rather than four so I’ll be showing you how to wire that in fairly neatly it’s quite a difficult task to get it compact but I think three by nine by whatever it Is 1 2 3 4 5 3 by 9 by 5 isn’t too bad considering it has to always be 9 long anyway a little bit disappointed about this bit here but it’s not a lot you can do really so I’ll take you through that and then I’ll show you how to add these Note blocks so that you get a bit of noise like this when you’re entering your code which I’ll do now so 9 8 we’ve got our little activation noise so I’ll be showing you that and then I’ll just quickly do a brief bit on how you’d extend the four-digit combination lock Up to 9 it’s pretty self-explanatory but I’ll show you that anyway so yeah stay tuned okay so the first thing we’ve got to do is our keypad bit which is three by three buttons on like that and then obviously come out the back and just Going to put a torch on each block like that so it’s not brain science so once you’ve done that you’re obviously now isolated each torch to a button and then you’ve got isolate that further and run it into the decoder so we’ll start with the bottom line here and we’ll start in The middle so we’re going to dig down 5 like that 5 long redstone dust repeater the start there and then appear like that so this repeaters here just to stop it cross talking with that torch so now if we press 8 we’ve got our line completely independent and these don’t affect it at All as you can see so that’s that and then these two at the bottom here seven and nine are just out like that so super simple for that so now our bottom line is completely independent and it’s going to run into the decoder that’s going to be in here so that’s That and now this middle torch it’s going to have a block there with a repeater on it and then that repeat is going to power a block with a bit of redstone below it like that and then these torches also in the middle row they’re just going to have two blocks With repeater there so this repeater is picking up this torches power redstone dust there and then just two repeaters out like that again into this row here and then you just do that on the other sides so two blocks off from this torch repeater there redstone dust and two repeaters out like that So that’s your middle line done so now if you press six we get this one press five we get that course of register in the middle and if we press four we get this one so they’re all independent and then our top line goes like this so if You want to do three got a block there above that redstone with a bit of redstone dust on top and a block here registering comes down and a repeater there like that so now your three is independent and then one is exactly the same on this side Two blocks like that redstone dust and then a repeater there so you’ve got all eight apart from this one in the middle which is the one I’m disappointed about but what you’ve got to do is run three out one down like that so you bring it All there and you put your peer at the end connect up with redstone dust actually that needs to be a repeater facing that way just said it doesn’t crosstalk with the torture number three and that is it that’s it done basically so now reline is independently controlled by These buttons and they’re going to run in to your decoder which is this here so if you guys have no idea what I’m talking about obviously I’ll put the annotation links and all that stuff in the description for the full tutorial on how to build the four-digit combination Lock which is exactly the same system as this all we’re doing with the nine buttons is obviously adding in this which people asked me about and also extending the length of the decoder here so normally in the four digit decoder it’s only like that with four torches on Top obviously we’ve just extended out five here so that we can then run it into the RS nor latch array so let me just explain a little bit about the note blocks and how we do extend it alright so if you want the note blocks in there Which i think is quite a nice little touch to have sound every time you press the button you’re just going to run these blocks along here and then note blocks on top with the torches that now obviously means every time you press a button it’s just going to turn off Whichever line it is here and allow this torch to turn on and play the note block so doesn’t matter which one you press still have notebooks like that and then you don’t do any kind of decoding from this you just run repeaters here like you normally would and then you have Your second line or rather you’re actually your first line of your decoder here and then choose whichever gap you want to be your code now that’s that with the note blocks but if you wanted to just have a decoder straight up without those you’d have to change it Slightly and I’ll explain why because there’s this redstone cross here when we go into our decoder which is a pink block there with the torch and then the red reset line above obviously you’ve got to be able to power the Redstone below here which then runs off into the RS nor latch array as you go no but because it’s just redstone dust obviously this isn’t getting power whereas if it was the repeater that was going into it as you can see it’s now getting power so all you have to do is extend out the line of repeaters by one Like that and then you can just run your decoder properly like that now and obviously set your code so that’s just a heads up about this cross of redstone here you do need to extend out one if you’re not going to use those note blocks but if you do use the note blocks You don’t have to do because you’ve got the block there like that and then you’ve got repeat on the other side which does pick up that signal then it goes into a normal decoder so that’s just a heads up on that one and yeah I mean as far as expanding it from the Four digit combo goes I’m sure you guys are pretty much worked it out you’ve normally got four like that and you’ve just added in this extra five lot of lines like that and it just yeah it works on exactly the same principle so yeah that’s it dangerous watching you Video Information

Dingdong! In this video I take a look at how to build and install a nine digit keypad to the combination lock circuit I previously showed (links below!) Thanks to everyone that asked for this tutorial and I hope it helps!
