I don't even play minecraft anymore, haven't watched a minecraft-related video in a while and still devoured this vid this is high quality content, well done
Those demos must of taken so long. every cut has a beautiful build and a combination lock! 30 Seconds of footage probably weeks of work. you deserve SO much more subscribers!
Thanks so much! 🙏🏼 I did spend a ton of time on those demo builds. I'm glad it was appreciated! Still, it was much less than the time I spent iterating on the redstone. Also, I want to give a shout out to my family members who contributed to my demo home with the base 12 combo lock.
I would absolutely LOVE to see a tutorial for this lock. Just watching the video i already have so many neat ideas for interesting secret entrance builds using this beauty of a redstone masterpiece.
One idea I had for a combo lock functioned by using firework stars as a hashing algorithm, as you could use dyes to represent each digit and the crafter to input them into in the order they should be specified, and the output firework star would only be able to stack with the one in the checking mechanism if the combo was the same. The flaw, of course, is that it relies on a fuel source of gunpowder and at least as many unique dyes/firework start ingredients as you want to use for the system. At least all of that can be automatically farmed, but it’s still not very convenient just for a combo lock.
How to get 100s of subscribers 101 lol. It was definitely a fun watch, and very detailed, but not too much! Thank you for oyur content, and effort into the Minecraft Redstone community!
God tier redstone content. I was JUST thinking the other day about how to make redstone videos more entertaining, and this is 100% it. Astounding presentation and amazing storytelling without being overly energetic and draining the viewer before you actually got to the meat of the video. I don't usually watch such technical redstone, as I'm mostly a survival redstoner, but the discussion of the more technical aspects of the design were both informative and easy to digest to the point that I feel like I could work with them at a basic level now. I also want to put this design in my world, and it's almost inspired me to keep chipping at this problem. I'm really curious what sort of things we can do to retain the speed while reducing the footprint of the digits themselves, as some of my thinner-walled builds don't have enough space to implement this combination lock without going down like 50 blocks. Even if the total volume is increased, the linear dimensions prove more trouble to fit into the nooks of my builds
Thanks so much! 🙏🏼 As far as fitting this combo lock into your builds, the signal can be sent down as far as you want. The examples at 52:23 show 50 block drops and they could be extended even further if needed.
amazing video! I was not expecting to get mentioned, that was a nice surprise ^^ in a few parts of the video, you mention comparator priming by using two observers, one observing the other, both powering an output line. this isn't actually what is referred to as "priming", but rather just a pulse extender that extends the pulse from 2gt to 4gt, causing the comparator to output a 4gt pulse. to achieve "priming", you need two observers updated at the same time, powering the same line. this will cause the comparator to output a *2gt* pulse, and it also works with torches. MaizumaGames has a video on their channel covering it ^^
Thanks @SacredRedstone, I'm honored! 🙏🏼 Giving proper credit to people's contributions is super important to me. Thanks also for your point about the two observer configuration actually being a pulse extender. I had originally thought so too, but I've encountered some conflicting information about it. Some redstoners (e.g. vinesthemonkey and FEARLESS_Z_) have defined comparator priming as a situation in which a 2gt priming pulse is followed 2gt later by another pulse (of any length), resulting in that second pulse being processed by the comparator instantly, using that second pulse's signal strength. In MaizumaGames's video, he refers to the situation in which two observers are simultaneously powering the same line as "double powering." I'd like to use the proper term, so if you have some other references, please send them my way!
This was really fun to watch and I wonder if you could use the '10' and '12' in the 2 bookshelf design as 'reset' and 'submit' buttons respectively. The 11/reset wouldn't have to change because a wrong digit just resets the lock anyways. Having to submit the key seems like a cool feature if that is possible.
Thank you! I forgot to mention this point in my video, so I'm really glad you brought it up! As you said, if you limit yourself to digits 0-9, the '10' already serves as a 'reset' button. And you can always add a trailing '12' to your code to serve as the 'submit' button.
The book placing and removing sounds are so crunchy, it tickles my brain. I would purposely make a combination lock with 2000 digits just so I can listen to that sound for 8 hours.
Is the answer to the riddle Helios, ancient greek Titan who chariots the sun across the sky, and famously sees all? If you encoded it on an old phone numpad, that would be 435467
I believe the code is: 3121. Explanation: Hades' dark minion: Cerberus, the three-headed dog guarding the underworld. He who witnessed from the sky: Zeus, the king of the gods, who could see everything from Mount Olympus. The flight of Daedalus & Icarus - his son: This points to the famous myth of Daedalus and Icarus, where they used wings made of feathers and wax to escape from Crete. Icarus flew too close to the sun, melting the wax and causing him to fall to his death. Elytra's first test, so sad he must die: Elytra is a term for the hardened forewings of insects, and it seems to be a metaphor for the wings Daedalus made. The "first test" could be the initial flight, and the "sad he must die" refers to Icarus' fate. So Cerberus: Three-headed, so 3. Zeus: Zeus is the 1st of the Olympian gods. Daedalus & Icarus: Two figures, so 2. Elytra's first test: The first flight, so 1. Also based on the fact that the riddle contains 4 sections, im assuming the code only has 4 digits. Or it might be just 121, since it was shown that the code is of only 3 digits. Or maybe 311, depending on how you see it.
Analysis of the riddle: “And invoke He who witnessed from the sky” So it’s not a mortal, owing to the fact that none of us(probably) can fly “The flight of Daedalus” yadda yadda yadda. The last few lines don’t matter much, since they all reference that time the inventor and his son escaped and the Icarus promptly falling into the sea. I thought it was Helios for a second but apparently from another comment it’s not him? So I’m out of ideas.
I'm also thinking the code may be based on "APOLLO", except rather than mapping to phone keypads like the other comment, I think it might be a 1337/SHELLOIL (71077345) code. Possibly 077064. (The main problem with this theory being that "P" doesn't really fit 4, 6, or 9) _Could_ be HELIOS with this logic (501734)
[SPOILER] 501734 is correct! Great job!! For those who still don't see it, enter that into a seven segment display like a calculator and then turn it upside down and it reads, "hELIOS"
25:26 Is there some library of music for youtubers to use? I'm pretty sure I've heard this song in an ActionLab video and now that I think about it probably more than that too
Yes, there are many music libraries out there. I use Epidemic Sound (paid) as well as free sources such as the RUclips Audio Library. That particular song is Particle Emission by Silver Maple, which I found on Epidemic Sound.
I feel like Redstone showcases have gotten quite stale. Mumbo did try to create new formats such as the whole different mobs doing redstone. I feel like that format has seen a lot of life in the command block/datapack space. (Maybe the format originated there? Not sure) This is quite a fresh take, with the effort into building a set around the redstone. while there has been a steady rise in explaining your though process, e.g. Squibble and his impractical redstone
I have found a very slight flaw in the design, in that if you type in the first digit of the code _then_ the full code the code isn't accepted. Which is understandable, but still interesting.

Yeah, you're right. This is the explanation of those two cases: 3 => wrong 1st digit, so lock resets 2 => wrong 1st digit, so lock resets 1 => correct 1st digit, so expect next digit to be 2 1 => wrong 2nd digit, so lock resets 2 => wrong 1st digit, so lock resets 3 => wrong 1st digit, so lock resets 3 => wrong 1st digit, so lock resets 2 => wrong 1st digit, so lock resets 1 => correct 1st digit, so expect next digit to be 2 2 => correct 2nd digit 3 => correct 3rd digit and code is complete I think there should be a way to guard against extra leading digits in all cases. I'll need to give it some thought. However, if your code is sufficiently long to be secure anyway, I don't think you need to worry about it? For example, if your code is 7 digits long using digits 0-9, there are 10M possible codes. Still, good to know this is the case. Thanks for pointing that out!
I've actually worked out a pretty simple solution: at the end of the combo lock (next to the 1st digit in the code) add a 2 rt repeater leading into a comparator pulse extender that leads back to the return redstone line. When a leading digit is entered within 3s of the correct code, the pulse extender prevents the first digit module from working. Without any leading digit, the first digit module is able to lock in the OFF signal before the pulse extender takes effect.

At 15gt inputs and below, not only does it not work, but it actually breaks, with minecarts rolling away.
