Minecraft released another 1.21 snapshot 23w43a introducing a brand new redstone component, the Copper Bulb. This video will be THE most extensive guide to use the copper bulb to its fullest potential. We got counters, we got new memory circuits, and... a new world record? Again? And I called it a stupid name just to spit Mumbo lol.

@@CraftyMasterman What about a certain 9 digit passcode that has 9 numbers to unlock your base with these blocks like your passcode will be 163585443 to unlock your base?
It's insane how we got two revolutionary items in this update, and possibly a third one (the new spawner). And the copper bulb and crafter are already getting used for making giant farm loot compressors, all item crafter, lock combinations, number counting systems, and a new and improved compacted xor gate. Such a revolutionary update

They really undersold this update at minecraft live. When I saw the stream I was thinking "well, this updates kinda mid"... but no, it's just that minecraft live was kinda mid lol
@@Fiz1zy When the minecraft update is so big that minecraft live became so mid
It’s the Industrial Revolution update.
@georgeofhamilton true they did they say it was a tinkering update honestly the thing I'm most excited for is how cool the copperbulbs are gonna look in redstone builds like there's finally a excuse to have flashing lights in restone builds.
Would you rate this more or less revolutionary than the comparator or hopper introductions?(Though maybe the hopper is an unfair comparison, since without it many things would just not work)
Personally, I would’ve name the gate like, Michael or something. It seems like a good name for it.
This a play on Turing's love interest when he was alive?

that's such a mumbo thing to do
wouldn't the copper bulbs drastically reduce the size of minecraft computers? Since the bulbs can store "data" I'd imagine someone could theoretically create much smaller RAM and CPUs
CPU size wouldnt be affected too much (aside from smaller xor gates would could improve the size of full adders) but I think it should make memory smaller. I've not had a chance to mess with it myself yet but I think it could drastically improve the system I've been using
for certain applications yes but also there are already other minecraftism ways to store vast amounts of data like using storage containers and named items
@@Zreknarf you cant generate those automatically with redstone though, thats the problem we're trying to solve
@amyshaw893 sure you can with droppers and water streams or hoppers and minecart chests but the delay would always be measured in seconds instead of redstone ticks
I imagine those giant calculators can be compressed way smaller now

One thing i've not seen people talk about with the copper bulbs is the INSANE value to computational redstone.
If you've ever seen those videos of people creating computers in Minecraft, one of the biggest pieces of that computer is usually the RAM or Registers (memory units) and that's because memory modules are *MASSIVE* just for a single bit, and making enough memory to store anything useful just explodes in size. These Bulbs are already making memory modules very very small, and writing/reading stored information in binary just became a LOT easier.
Now one bit is one copper bulb, plus the movability could make for an actual spinning disk hardrive
@@Vekkizunt is it possible now to run Crysis in minecraft?
@@Vekkizunt you just need a counter equal to the tape size then we increment the counter every time the tape is moved. That way we know exactly where we are in memory and we can go arbitrarily long with these.
Only problem is resetting the memory
@@cmdrghost365 Honestly, that shouldn't even be a problem. Just run a redstone line under/on top of the whole tape. It would be a bit more difficult to reset vertical tapes but they are less convenient to work with in the first place.
8:30 That aged poorly 😅
fr bro
This whole debacle makes me glad I only play modded. I can't understand on what planet it makes sense to do a thing, have people universally praising how you implemented it, and then decide you need to take it back.
I mean FFS, make a SEPARATE bulb if you think that there would be utility in having it be the way it is after the change. Maybe using Gold or Iron?
The ONLY way in which I can see it maybe even being arguably better to have them NOT operate on a 1 tic delay, would be something to do with lag? But there are SO many other lag issues to deal with before that becomes a real concern.

I'm not great with redstone but I think If you managed to stack those Turing machines on top of one another you could make a programmable sheet that could be used effectively like those music boxes that you can punch holes into a piece of paper to write whatever you want on them. Could even be used as a punch card type thing to operate machines differently depending on how you program it.
genius.

You should be able to do that with just one long Turing machine, you can just have it load in a few bits play the music, then load the next bits, though admittedly this would be a tad slower. You can also do this already but with other blocks like cauldrons.
More you keep showing off these cool things and banter with Mumbo the more I want to see you in HermitCraft

7:02 with such a modular system, you could create the ultimate password machine. Where you do not just input the password to unlock something, you have to input a bunch of correct passwords to unlock it, simply by just taking a signal from each of those output lamps.
YOOOOOO it's like a double verification system
you can do that way easier and safer with actual 2fa just put an itemreader in next to the password pad and have the redstone lines connect with and logic to force you to know the password and have the correct item
you can make the filter even smaller by removing the two solid blocks next to the observer and the bulb and moving the observer and bulb in that place. you still need 41 items in the first slot so its overflow proof.
I really wish pots we allowed to take input from items placed on top of its opening. Then you could reduce the need for the overflow.
But also it'd be cool to have a more decorative storage solution that can also accept items via the environment instead of right clicking.
He could also put the observer right next to the first comparator, and have it facing into a solid block with the bulb below, making it not use Redstone dust and saving the entire layer it is on. Or to get even more compact put the observer reading facing the first restone dust, and move the second comparator directly next to the hopper, and the copper bulb below the observer, making it a tileable 4x3 and making overflow needs far less than 42 as it only has to be on one of the changing points, though theoretically in order to not accidentally lock itself it should be on the last changing point, but funnily enough it will do that on its own if it's needed
To explain the 4x3 one better from left to right you have left top as Redstone, left middle as observer reading the Redstone, left bottom as copper bulb, middle top as comparator reading hopper, middle middle as anything a comparator can be on, and middle bottom as comparator reading the bulb, which is why it's 4x3 because comparators don't float, right top as a hopper pointing towards the comparator or away from it, right middle is hopper pointing right, this is the output, and left bottom as any solid block. You need 44 items so that it can't break itself and you need to start with the lamp on while the 44 items are in the top hopper
Another realization I've made is that the same sorter as described above would have worked with 2 droppers in the left column facing each other and another comparator instead of redstone dust on top the observer
Wait if I understand you right you're making it so a signal strength of 3 will bleed over into the adjacent slices.
The multi save will be game changing for computing redstone!! I’m way too excited for this update 😊
It could already be done smaller with repeater locks
Really compact XOR gate but the fact that it's only useful as long as it's impossible for both inputs to change in the same tick makes it inconvenient
true, that is a problem
I think there's a really easy solution to this. Just add an extra observer to one input.
@@nikkiofthevalley what if one of the inputs changes a tick off from the other one
@@Catman_321add a copper bulb to phase the input signal with 1 tick offset. Then just make sure that the input signal does not do the anti phase 1 tick offset.
Makes it useless unless you're optimizing for size and not for speed
I wonder if you could make a 1 bit memory with the inputs of "value" and "hold that bit" with locked repeaters.
Just a funky little idea
Could you make a system with Similar inputs as that but with the copper bulb?
The entire idea is:
V = value
H = "hold that bit"
V H Q
1 0 1
0 0 0
x 1 Q (Q is set when H is 0)
Are you talking about a D latch?
This is called a D latch. The input is called D for data and the "hold" is called E for enable (or sometimes '
@@partywumpus5267 ahhh okay I knew it had a name and completely forgot it
I love the copper flopper and the crafty crafter counter!
The sorting toggle system could actually be stupidly useful for deciding what items you want to actually collect with a mob farm and just have the rest of the items put somewhere else. Or you could have a system to determine whether or not you want to autocraft with a specific drop. Many new possibilities!
You can make a completely automated dispenser farm in theory.
-witch farm for redstone
-mob farm for string
-bamboo farm for sticks
-cobblestone farm for cobblestone
All of those are completely automatic in theory
This really makes industrial “districts” super rewarding since you can combine 20 small farms to make whatever you want
what I love about this; I am not good with redstone, as a kid I even struggled with a piston door where you can open it with buttons on both sides. with this its so easy
same
It's crazy how many things this blocks makes possible/better
12:06 The subscribe button does have a rainbow sliding effect when the youtuber asks you to subscribe. It did that in some ARK video I watched yesterday, it were pretty cool, don't know if it's something you gotta do with the video before uploading or smthn.
I feel like some of this tech is going to be EXTREMELY useful for densifying memory for redstone computers. I haven't built any computers in years, I might have to get back into it though to try some of this tech.
Especially with that turing memory strip, you can now program a redstone computer on the fly with just that strip!
Sadly copper bulbs got removed the 1 tick CD :(
Mojang “fixed” functionality of Copper bulbs, there’s nothing we can do…
Now they're just redstone lamps that can be dimmed :(
@@micahscott3895 not really, it does hold data by staying powered when moved, but other than that it pretty much is
Well, those memory builds are going to be a nice addition to storage system and auto-crafters. I can already think of 3 uses. Displaying the current state of your inventory, selecting items to retrieve and selecting which items to auto-craft.
10:22 I'm sure it has a great personality
( ͡° ͜ʖ ͡°)
What I thought of was using the copper lamp or whatever the name is for either RAM or general use binary in computer, since you could store them side by side, double the bits in the same space (8 bit computer, with remade systems could be 16bit)
11:20 you made a turring machine???!!! This means that Minecraft could simulate itself within itself!
Turing-complete computers have actually been being made for quite a while, and a simplified clone of minecraft's also already been run on one of those too
Just yesterday I made a huge music box using a piston feed tape of 539 copper bulbs as the memory (the original idea was to emulate magnetic tape, but the hertz is way too slow for anything other than audio)
You have cursed me with inspiration. When I hear turing machine I think of Brainfuck, and I know how to make an interpreter for that, and now I have many many ideas on how to make that work, and now my plans for the next week are going out the window.
Now that we have the copper block for the tape, the main obstacle to making a functioning Turing machine would be getting the states to work. Though some sort of decoder like the one you showed might be a pretty good way to do that.
You can use the machine at 2:30 to store the state. A two-dimensional array to store which state is next is probably easier than an extra decoder.
And then Mojang tooketh away.
tbf i've seen this done already a few hours ago, but it's still cool how it's being picked up.
iirc when two inputs change together it does break, though.
I like the multi-combination saver because you could make some really cool stuff where you have different codes that do different things. Doors that open in multiple directions / doors to a secret base where you choose which door opens by its code, controllers for multiple related systems, etc
The thing with making stuff so small and simplistic is that other people also probably came up with the same idea (e.g. mousetraps irl)
However, the crafty craftet counter is a cool name.
Doesn't your 2d combination lock recognise any combination with the correct amount of on pixels in each column as fully correct? It seems like the whole wall thing at the end just "counts" each column and can't distinguish between a pixel being higher or lower.
I really like the coper bulb sorting system i was actually thinking about its just before i watch your video its also make that we can only lock one hopper so by putting another hopper below there is no more 1 item left in the hopper
For a fully functional Turing Machine you‘d still need states, so eg. in state two, when reading 1, write 0, push left, change to state 3. I‘m not great at redstone, so not 100% certain how you‘d accomplish this in as little space as possible, but I‘m definitely looking forward to the first universal turing machine in minecraft :D
0:49 HANG ON you're in contact with mumbo?
I doubt it

@@CraftyMasterman 👀👀👀👀👀
“So I broke craftymasterman's heart by not subbing 2 his channel” (that should be the new title)
what'd be really cool is the piston feedtape becomes a combination lock. Not only does the correct pattern need to be on the tape, but it needs to be on the correct position as well. So you're just working on putting in the combination, then you get to the last bulb, it's in the right position but the wrong setting, so you toggle it, a trapdoor drops you into your secret chamber, and the automatic increment that moves the tap automatically turns off the circuit again and the trapdoor closes behind you.
If the person after you knows it has to be the right combination, then you have a long head-start as they need to cycle through the entire tape again. If they don't know the combination, then you're basically safe forever
Oh good - someone else is commenting on the possibility for a turing machine - that's fantastic, I'm real excited to see what comes from this
i wonder who will be the next person to name something from a snapshot. will it be mumbo? crafty? mumbo? crafty? who knows
Mumbo and Crafty will do the fusion dance THEN name something.
with the memory tape we can finally make morse code finally make the first long range communications system in minecraft bro (edit this is probably going to get burried)
The memory storage would be cool in industrial districts. Imagine going to the panel and clicking certain number and the specific farm turns on. No levers for each one. Just one
Or bubble elevators
11:55 That machine gives me an idea for a combination lock. It's fully invisible until you place and press a pressure plate, then the tape brings the bulbs over in a full row, then you place a bunch of buttons or a lever or something to toggle them, then use the pressure plate and they go back into the wall to be checked, leaving the mechanism entirely hidden. Break the buttons and the pressure plate to hide it, go inside the door, and a button inside resets the lock, closing the door. The same button also opens the door from the inside.
Who else is exited to use the Crafty Copper xor Corridor
Anyone else got no clue what he is saying but your still watching the video anyways
Yep
I just realized, since you can move them and they’ll still store their on off value, you could theoretically read/write them like a tape and convert that into an image or something
If you did an 8*x it would be x bites of memory of you had it store all the possible combinations it would be ram, if it was just a ticker tape it would be rom... You could also store different images in the display version of the lock as well and use an input to choose which preserved output is displayed. Love it all of this has been buzzing through my head since I heard how the cop flop worked.
As soon as you said the copper bulb is pushable my mind went straight to a turing machine. So happy to see you had the same idea! Does this mean redstone is now turing complete?
It was Turing complete before already. People have built small CPUs.
It's always been Turing complete
First
No.
the revolutuionizes computer memory in mc as you can store a bit in 1 block you can just move it around thats so nice
we already had a similarly compact "xor gate" using pistons and observers. I discovered the 4 block design within about an hour of the snapshot dropping but the synced inputs breaking it reminded me it's just the nature of t flip flops to act as pseudo-xor gates. it would be super cool if mojang added a way to detect how many sides are being powered each tick so an even number of faces being powered did not change its state. then we would truly have a 4 block xor gate
I hope they make the redstone output scale with oxidation, so that you can make even cooler things with feedtapes
I'm really curious whether Mojang is aware of the big redstone applications when they make block like this one or the target.
Like did they just thought "it would be cool to a have toggled lamp for interior decoration" or were they aware that it would be used for memory storage?
I think the most important thing you can do with those blocks is that you can transfer memory with pistons now. If you want you can make a recording tape out of that, record it with commands and send to another room for processing. Or maybe you would want a flying machine that has it's settings memorized with those.
6:20 seams like a nice way to have a ROM you can look into.
You can give some key, and it gives back that value from ROM.
There are probably better ways to do it, but this is a cool way to do it.
The sorter is neat because it can replace the existing hopper-pointing-down-into-dropper version that's one block less tall than the impulseSV version so sometimes fits better, but without an unlocked hopper! Has the downside of lighting updates when activating/deactivating but that shouldn't be too bad when using the oxidized ones I think.
the storing combinations thing is actually awesome, you could make one machine that stores the combinations to do a tonnn of different things, all from one panel!
CraftyMasterman: Oh look, the copper bulb has a really interesting delay. I will make a record breaking contraption.
Minecraft: Nuh uh
The feed tape + music disk encoder. have a counter system keep track of how many bits have been written, and at every X bits, you read what has been written, and select an appropriate music disk/boat
5:50 This is a real genius invention. I can see this being used as a control panel to toggle many different contraptions. Say you have many farms all in one spot, now you can toggle specific ones on without going to them specifically. Say you have a structure rigged with redstone booby-traps, now you can control them all from one spot.
I am so excited to see new versions of compact Minecraft computers utilising this block
I love how in the update where mojang added the AUTOMATIC CRAFTING TABLE the AUTOMATIC CRAFTING TABLE isn't even the most groundreaking game changing update.
These are all real cool applications but i was pretty shocked when I realized you made a Turing machine demo, like add a few more things and you’ve got basically the smallest computer and storage setup in the game so far
9:42 that's essentially survival friendly vanilla mc picross/nonogram puzzles. I could imagine this to be a fun feature for server activities
I actually have a design for a 5-button programmable combination lock I made years ago, but it’s way bigger since there was no copper bulb back then. I’ll definitely have to revisit more stuff I’ve made to see how the copper bulb can improve things
yeah it doesn't add like necessarily any new possibilities though by making things compact it does make more things possible or viable in survival or in builds in general if your button selector panel is bigger than your base its a bit over the top but if its just a small part more people will use it
i knew you would releasing some kind of thing quickly after this new cool and absolutely compact feature
The first thing I thought when I saw the Turing machine is that now building Conway's game of life (and other cellular automata) in minecraft should be easier and more compact
If the comparator doesn’t have to be counted, a 3 block XOR gate is possible using two observers on either side of a copper bulb, pointing at it.
If you are counting the observer in the volume, it’s the same cubic volume.
That was some great contraptions, its really cool what you can make from the copper bulbs!
Btw, I personally think you should’ve called the xcop; “The crafty copper cop”
2:21 I can totally see this getting integrated into a storage system where each panel allows for selecting a specific item type via hopper minecarts or other modes of item transport.
pretty sure you can already do this without the new block
@@kokomaniia yeah but this would be significantly more compact / easier to set up without as much redstone knowledge.
there's a flaw with the xor gate as if both lines were powered at once, it will only fip once, turning it into an xand gate
12:06 fun fact, the subscribe actually does kinda do that, it shimmers sometimes when it hears the word subscribe
Sounds like a neat thing to use the xcop gate, i wonder if trapdoors and bulbs along with building and redstone could make the reach be farther.
This can be used to make waaayyy better storage for redstone computers.Also beside this when pipelining it’s even faster
if you smash together animation banner and 2D bulb lock you possibly could run an animation savend on bulbBits
2:40 TIP: if you place the droppers facing in to each other and fill them up with something cheap like wooden shovels, you can get rid of the clicking noise
with the 4 part memory thing you can make it open 4 different vaults or doors to rooms in a secret base or even make it so you need all 4 passwords to open a door
i love that xor tho it would turn itself into an xnor if you flip both levers at the same time
to the memory system, add now a function that you have to put in specific codes in specific order and you have youre voult "sequence master lock" xD
2 revolutionary items get added to minecraft, everyone likes them
mojang: something aint right here
I think this was intentional on mojang’s part to make one of the most necessary redstone circuits a lot simpler for beginners. Probably to be in theme with “tinkering” in this update.
Copper before: almost useless.
Copper now: NECESSARY
BRO. I just realized, with the copper bulbs and crafters it's technically possible to create a sorting system that sorts items by like categories. Well from what I'm thinking of it would be limited to sorting based on the specific type of material you want to use as the "category" like if it's made from specific types of metals and such. I think you could even tweak the material requirements for those categories so things that might use that material but aren't mostly made of that material wouldn't be labeled in those categories. This way you could create sorting systems that use less end point storage containers. Like instead of a massive warehouse built in to a mountain, you could end up with like a small garage. Right now the idea is in a rough draft phase and I haven't experimented with categorization yet, but it is totally doable.
If you combine the Turing machine with the combination reader (with multiple outputs), you can make some really cool things
Would you make a tutorial on how to compact your redstone builds?
I've seen a lot of basic tutorials, but not a single one is on compactness.
I like to think of myself as mid-advanded redstoner (I mostly know what to build and can build most project on my own) but it seems like every build I make is quite large.
As soon as I saw this my mind said "TURING MACHINE". You actually did it. Now all we gotta do it find a way to read it and do something with it
The sculk sensor needed many changes for it to be even considerable in redstone circuitry, but this is just already perfect. And Purplers has also made a video pointing out other great things about it, specifically its single-tick delay. Now that Mojang's created the perfect redstone block they just need to not ruin it.
rip...
Redstone computers will definitely become easier to build, smaller logic gates, easy binary incrementation and smaller memory will definitely help.
Now the only problems are speed and wire space.
I wonder if someone can make a fully realistic combo lock now: 0-9 buttons, enter and cancel button, and the ability to change the combination when you have the correct combination
Bonus if you can make it compact and look like an actual keypad
3:53 I just made a 10 bit customizable combination lock with a master key pad and an entry key pad. AND YOURE TELLING ME IT DOESNT HAVE TO BE THE SIZE OF A SPACESHIP?!
Deactivate the bulb in an activated craftor gate to get something else (xnor or "nxor" depending on the lever setup when you deactivate it).
The Turing machine idea is pretty cool, and I'm curious how one would go about implementing the state logic. I might have to try it out.
The system shown off at 7:00 could easily be used as a simple CPU OpCode system and I'm absolutely here for it
Make sure to use the crafty crafter to make a sword when an xcop uses a copfloper.
Can you please make a full tutorial on how to build all of these and keep up the great work.
