This is one of the most entertaining and informative tutorials I've ever seen.

[@ThatDominykas]

Honestly, I can totally see why Mumbo encouraged to come and watch. It's a genuinely great video and I absolutely loved it. It's a very good take on a generic tutorial style video. The introduction is really fun to watch and explains well why your design is better than some others. The tutorial guides through why each circuit is needed without going into too much unnecessary detail (which can really screw up the tutorials pacing). And overall the design looks really cool at first glance. It would definitely take me some time to wrap my head around, but the circuit board feeling is unreal. (not to mention it works on both JE/Bedrock) Amazing video, great contraption. I'm truly impressed and I really hope your channel only grows from here on.

[@leothi2]

Bruh there really are people out there managing to use redstone length as a tool in their kit. I would still be thinking about how to isolate each button's input. Edit: spent some time retro-engineering it and finally understood how all of this works! So not only did I learn how to make a cool system, but I also improved my redstone skills by seeing new ideas and solutions, all thanks to you!

[@calvinpetri7391]

How does it work? I'm a newbie and my brain is melting.

[@grantsolomon3473]

@@calvinpetri7391 I would suggest doing the same thing this guy did and retro-engineering it. It would probably take a video twice as long as this one to explain it. If you are new though, I recommend familiarizing yourself with less complex principles first because this requires quite a bit of understanding of less complex concepts. If you know about locking repeaters, comparator subtract mode, comparator signal strengths, etc you might understand this. Otherwise go learn all that first. I hope this helped!

[@leothi2]

@@calvinpetri7391 so I don't really know what you mean by newbie, but you need to know about redstone strength, comparators and locked repeaters. If you don't know that you really should start by learning about this. First of all, the input (the white circuit and the first chest) is designed to be a redstone strength of the button pressed, plus one. The point is that you can compare this input with the number you want, that you put in each chest, to have a strength of only one when the correct number is pressed. Then, you have the blue circuit. The circuit is very simple in itself. You'll see that the point is to cut the output when the right number is entered, in fact. If I'm correct, the output is supposed to come back one tick before the first test, the green circuit that we'll see after. The point is to only have one tick on the return line, the yellow circuit, I guess to avoid to overflow it with a signal that is too long, and have more than one locked repeater powered at the same time on the return line. Tbh I'm not really sure, I even tried replacing it with a persistent redstone powering and the system still works *when I use it gently*. So, I'm guessing, a security. If somebody can explain this part to me in details it would be nice. However the pink circuit is the most important one in the system. The line of two powders is powered by the input minus the number in the chest, and thanks to the white circuit above, if the right number is entered, only one redstone dust will be active. This will nullify the output of the other comparator coming out of the chest by powering its side, and unlock the comparator on substract mode on the return line. If the input is below what's wanted, nne of the two redstone dusts will be powered, and if it is above what's wanted, the repeater will be locked in its powered state despite the comparator powering it being nullified, and the comparator on the return line will stay locked. At the same time, the redstone torch will be extinguished, releasing the memory of the repeater on the return line, that corresponds to the test of the number before. If the right number is pressed, the comparator will unlock just before the memory is lost, and will power the next module. At the end, the T-flip-flop is just used to control the output as you want. So, if I understood correctly, this system has the advantage of being almost impossible to break (I tried) because of the different parts not being very interdependent, but the problem is that the timings are tailored for stone buttons. Any other input's duration won't work. Also don't choose 4 times the same number as your code, because it will send a pulse each time and in the end, if you don't reset it with a wrong number, it will just open when you press the number you chose only once. For the same reason don't choose two alternating numbers like 2424 or 4949. But in the end it's a beautiful clockwork nonetheless.

[@builderbanana3620]

@@leothi2 So there is no way to trigger signal strength other than from stone buttons?

[@leothi2]

@@builderbanana3620 you can, but you have to have it activated for the duration of a stone button, 4 ticks if i remember correctly

[@eelmail2077]

2 notes for anyone building this: if you are in 1.14+ and want to place solid blocks above the chests, use barrels instead! If you can’t open the chests and give the comparators a block update, they will read the chest as being empty! Barrels solve this issue. Second if you are setting up an alternate way of inputting the combination, the less power the combination lock receives the lower the number. You can also increase the input range by removing the nonstackable items from the first chest, each 2 removed being a extra input. Just note that this also means that higher value inputs will need more items in their individual chests/barrels. Otherwise great tutorial!

[@eelmail2077]

If interested I made my input device a NES controller and the input sequence the Konami Code, so that’s why I had to figure out the alternate input.

[@orionoth5547]

Genuinely bigbrain. I'm going to spend some time figuring out how it all works, and then seeing if I can vertically compact it any.

[@andrewmadilecy5704]

Due to the chess being exposed on both the top and bottom you can even make a automatically shifting password. It's not easy, but it's possible. Which is dope for things like prison doors that shift passwords every hour.

[@SergeantXray]

Yeah, with hoppers above and below the chests, locking and unlocking them, you can customize the passwords from elsewhere as well!

[@josephyhu]

Great tutorial! It was easy to follow along even though I'm clueless about redstone, and I've successfully built a 9 digit lock with an iron door and a reset lever inside and a pressure plate to open the door from the inside. Edit: Changed the reset lever to a reset button.

Finally found someone who actually understand how combination locks work worked on one myself a couple of years ago and managed to make one with droppers and locking repeaters and stuff to get the sequence right then i started searching to see what other people solutions were and i found no one that knows how to make locks with sequences other than you I even commented on the bowtieman video but i didnt manage to show my design anyway hats off for you for doing this glad to see people who are really good with logical redstone Edit: one of my problems were that the old good combination locks were really old and huge and my design was like 6 or 7 blocks wide first try and i didn't even try to compact it but i am sure if someone could get people back into the redstone hype train we will get back to the golden days of redstone

I tried my hand once a few years back at a ‘true’ combination lock on bedrock. It worked, but was too big and complicated to ever be practical. (It was a lever lock that used ‘bridges’ to carry signals and block the system if an incorrect input was used.) Really glad to have found this thanks to mumbo.

[@guillaumeroyer8071]

On a 1.20 Java server, I had a problem with bedrocked repeaters that wouldn't lock. There's probably a difference between the tickrates of the servers and the solo. I solved the problem by increasing the ticks of the repeaters with bedrock to 4 for those who that can help ^^. And thanks for the amazing redstone !

[@anthonydeluca9832]

Took me a minute or 2 to figure out how exactly it works but I'm thinking it has to do with the fact that the output to blue line must be off in order for the signal to go through, so you turn off the output of the comparator if it's right. You dont if it's wrong. And if it's too high you lock the signal of the comparator before it completely turns off... right? X -> R Y -> C X on if too high If correct Y on Neither on if too low

I tried the four digits button padlock, it works fine except that for some reason the bottom row buttons open it regardless of the combination. I'm on Java 1.18. I really don't know what I did wrong Also, what does the T flip-flop do?? It seems the button doesn't do anything (edit): nevermind I fixed that, I had messed up the t flip flop connection, but now it seems like none of it works. (edit 2): I messed up the chest where you had to put 8 stackable items. It works now! (edit 3): it broke again. (edit 4): fixed it, I somehow managed to get a piston door to push a block into the padlock circuit. I'm gonna keep updating this comment as both a vent and a showcase of my redstone incompetence (edit 5): it broke again. I'm gonna go insane. (edit 6): it appears that in my incompetence I've created a sentient lock. Sometimes when you put in the correct combination, it opens. Sometimes it doesn't. Sometimes you have to put in the combination again, because it needed time to ponder. Sometimes the lock is having a shit day and refuses to cooperate. We've all been there after all. I think I'm gonna name him Jimmy.

[@vikovitch]

depending on how you may implement the input method, (i am using item frame) it may be possible to just spam the button on any setting and it will eventually somehow work. i found this is easily fixed by changing each module so that the repeater that goes into the repeater that is powered by the comparator going out of the chest (the repeater right next to the blue part, but not facing into the blue part) is set to 2 ticks instead of 1. this makes it so that if the signal is on and pulses off for a short bit, the repeater wont get locked in the off state.
