I made a Minecraft security computer in 1 block
Mumbo Jumbo
In this Mumbo Jumbo redstone video, Mumbo makes a Minecraft redstone security computer in 1 block using Non-Euclidian Minecraft and the Immersive portals mod. This compact redstone build involves button combination locks, redstone seven segment displays, and other Minecraft security features. How small can redstone builds get with Non-Euclidian Minecraft? Using Immersive Portals to shrink redstone builds, we're about to find out. 1 block redstone builds, It's really quite simple.

    *Mumbo:* creates a large, stylish redstone contraption in a single block and tries not to confuse his audience. *Also mumbo:* 356 days in a year.

      Thank you, I was hoping someone would bring it up XD I'm hoping he did that as a joke. Like where it's simple to remember cause it's close enough but still wouldn't be guessable unless you messed up you numbers of days XD

    quick fun fact about immersive portals: you can do interdimensional redstone with a dispenser and a target block, both on other sides of the portal, meaning you can recieve up to 6 seperate signals, send 6 signals, or any inbetween, or even send near instant signals across the world with the portal helpers. do with this what you will. Edit: i forgot, you can make different size portals, so a LOT of inputs and outputs.

      @Miguel Tovar Guerrero the only issue with that idea is it cant really have up or down, as that might trigger the wrong hopper if you have lines of them, you'd have to go really tall for that to work, with dispensers and target blocks, you just have 2 blocks with no real limitations as to how they have to be set up, just have the target block directly across from the dispenser.

    Hey Mumbo, if you like this sort of redstone, I think you’ll be interested in what you can do with Super Circuit Maker. It’s actual small circuits, which can be inside each other. Things are going to get _tiny_ layer by layer

  • PearlyOctober

    Minecraft years are apparently shorter than real-life years. You learn something new from Mumbo every time!

    • Crabbo

      @Artifact that means in a minecraft year there would be 5.069444 days

    Hey mumbo, your build really inspired me to try a creation of my own. I was thinking about trying to create something that involved numbers on redstone lamps, but I didn’t know how to do so. I had watched this video a few months back and thought that this would show me how. Even after rewatching this video I am still struggling. I believe the biggest problem lies where the purple blocks are but i’m not sure. Could you maybe do a quick tutorial just about how to make the numbers display how you did, or link another video? This would be very helpful as I believe I am close but can’t quite get it. I don’t need to know how to do the signal strength and what not but just how to display numbers controlled by levers. Thanks.

  • Icequake

    This is crazy impressive! I'm surprised mumbo has never made a number display (or at least it looks like he hasn't)

    Instead of a normal door, portal mod so the “iron door” opens like a 5x5 pistol door (just 2 “blocks” tall so a 10x10). You could make a hallway after the door for another portal “correct you” since you’d be going through and changing size.

    I've been thinking of building something like a huge screen where upon entering a message like "Welcome, please type in your name _" displays, and if you're a registered user your name will be a code allowing access to some useless other things. Though this probably requires command blocks, and not "survival redstone" only.

  • Turtledud3

    One of the first redstone projects I ever set my mind to doing many years back was creating a 7 Segment Counter. It just counts with each button press, or you can run it on a timed clock. Now let me tell you, figuring that out as somebody who had no idea what redstone or digital logic was at the time was quite a task. I tricked my childhood self into learning the fundamentals of being an electrician to complete that project. I used a piston feed tape to control which number was displayed that was all glass except for one conductive block. When you pushed the button, the feed tape cycled once and move the conductive block to display the next highest number. When it hit nine, the next push activated the piston feed tape twice to get back to zero as I had one too many blocks to fit the feed tape. Seeing you build a seven segment has brought back many old memories there. Your's is way cooler with the portal though.

  • ABorinGuy

    "... the number of days in a year: 356" Ah yes, I see, by making the code *incorrect* to the real number, you have made the code infinitely more secure!

    • 火村美喜

      @Egerit Honestly, I watch Impulse and he's... not redstone illiterate, the way many others are, and is able to follow along with builds by Gnembon for example, but doesn't go very far with his redstone abilities. Mostly he just builds farms, doing some automation here or there to make it work. In fact, he feels more jack of all trades, above average decent at everything, but not necessarily *great* when it comes to redstone. Etho has been doing modded, and Tango hasn't put out anything at all since S8 ended, and while they're both pretty good at redstone, point kind of still stands: permadeath in hardcore is easier than redstone.

    • Egerit

      @火村美喜 Mumbo's good but everyone on the Hermitcraft server is insanely good at something. Talking specifically about redstone, Impulse, Tango, Etho, and a few others have a pretty similar skill level in redstone as Mumbo

That being said he didn't cover the room with obsidian or a portal wall or anything really so you could just walk *around* the door to get to the valuable items but that's not the point of the video

    That moment when you realise this mod can be used to miniaturise all his other redstone builds. Imagine tiny tanks blasting away at your feet, little timed flying machines bringing you your items at the click of a button, super computers that you can type into and they send you the items needed to craft whatever you enter into the search engine with a display field showing what you typed, a machine that can send you any potion at the click of a button. This mod is so versatile that you have unlimited options. In fact, combine it with auto crafting and the possibilities truely become endless.

    Could you try making a self-building bridge using ice/packed ice for boat travel, maybe using an infinite water source with a heat source to stop the 2 infinite corners from getting turned into ice or something with observers which will retract the infinite water source and move the machine forward similar to your other self building bridges. I think it would be very cool and very useful to make highways along the overworld automatically for boat travel
