I feel like "extremely practical to use in survival" is a relative statement 😂

Major props for giving your platform to give full credit to another talented builder.

“But I highly doubt anyone would need 18,000 oxidized copper per hour” You’re right we need to build 2 of the full-sized ones for 36k

“But I highly doubt anyone would need 18,000 oxidized copper per hour” 'Need' has never even entered the vocabulary of your average SciCraft player...

_You know what, after all that, I think I'm just gonna place my copper down where I want it to go and wait for it to oxidize there._ Thank you tho!

"He then followed up with simulation result from a program he coded himself using python" Minecraft technical player are on par with science researcher now smh smh

I find it so funny whenever he says cubic metre. My sense of humor is awful

I absolutely love that you were able to take their suggestion like a true scientist. We don't always get it right, and it's important to entertain alternate solutions which might lead to a new, better solution. With that in mind, a nice QoL feature for this farm might also be to have a "purge" system to get all of the copper in the farm out. Having a storage with an easy to get block like cobblestone which you can place instead of copper for 5 minutes of running the farm would clear out any copper inside, then the output of the blast chamber could filter this item into a separate shulker loader for storage. That way if you only need a portion of what the farm can hold, you can easily fill with copper and purge when it's oxidized. This would add a few extra pieces to the build, but might make it nicer to use for people who don't need the entire farm's worth of copper blocks at once

God damn, I’ve so much more interest on knowing how to optimize oxidation of a copper pixel block than on my final Calculus project lmao POG

This is so cool! Ever since copper was introduced, everyone just settled for using 4-block spacing, but I always wondered if copper oxidation could be made more efficient in terms of yield per required space. I'm glad to see that this is being looked into.

Some maths: The star shape around one copper block (=4 block taxicab distance) has a=128 blocks without the center block. In this example setup we have b=39 fully oxidised copper blocks around each not fully oxidised copper block. This gives c²=9.61%. Multiply this with m=0.75 for pure copper or m=1 for any other stage and then with 64/1125 (acc to mc wiki) to get the probability to oxidise the center block when random ticked. In our example this would be 0.41% for pure copper and 0.547% for the other stages. As each block is random ticked on average each 68.27 seconds, the mean time to get a pure copper block to oxidise to exposed in the shown arrangement is 4.62 hours (16641 seconds), for the other stages 3.47 hours (12480.75 seconds). Compare this with c²=100% and either 1600seconds (26.7mins) or 1200seconds (20mins) mean oxidation time per copper block in the original setup. But even though we lost a factor of 10.4 in oxidation speed, we can now pack 83.3 blocks to oxidise into the space where only one copper block fit in the original design (cell of 5x5x5=125 blocks). So the new design is (about) 10.4 times slower, but 83.3 times smaller for the same output.

Gosh darn dude, you're quickly becoming my favorite, which is hard for me because you're an Aussie and I'm a kiwi but I can get over our generational banter because of the genius and well done videos. Thanks so much Cubic, I learn so much from you

The way this farm is explained makes it feel like a TAS for oxidized copper

Me watching this video the entire time: I like your funny words magic man

I clicked on this video just to say that I really liked the title. I think that you could make a low-effort popular series of showing off how other people improved your farms. Anyways, Awesome video :D

Man, I took physics courses and got hella confused when you showed the P = mc^2 equation on screen. I was like "What is P that it's equal to a product of the mass-energy conversion equation?"

The logic and math of the 2 videos are so cool.

Ooooooh this is the new design that you were talking about- This is honestly a revelation as all the other copper farms (that I know of) place copper blocks 4 blocks apart. Props to WorstPacifist!

I find oxidizing farms and leaving copper to oxidize in a grid just really funny. The whole point is you just put the copper in place on your build and simply forget about it and let it oxidize itself haha. Then if you want it less oxidized, simply scrape it away until correct and wax it. Yeah it will take longer but why does it matter? The process looks really cool especially since the colors of copper are complementary and will usually go nice with your build in all states of oxidization.

When I first saw the design I had already given up on understanding it. But the way you carefully explained it made me understand it bit by bit a lot better. Major props for that! Excellent video

I was about to build this in my world when you pull the video just in time. Thank you!

I loved seeing the graphs and data you provided, this was super well written, thank you!

I can't comment again on the level of process engineering you have gone through in this video. This video alone made me think on how to prep for some of my projects in the workplace. I've even taken notes :D

I came for the farm, but that push limit extender has my attention

Damn dude. +1 sub. Thank you so much for the amazing simulation results and technical explanation.

So there are people making difficult graphics and analytics about a imaginary block in an PC game.....how much of a nerd can you be? And that is an compliment! Love the dedication ❤

That's what I thought. I was playing a game early on when copper came out and I wanted to make a copper roof. I noticed that it took forever to start the process, but once my roof blocks had changed, the new ones I added over time, because it was a slow build, they change much more quickly. To the point when the roof was mostly finished, it seem like any new block added changed in the blink of an eye. Yet, amongst the community there was this idea that spread that keeping blocks together slowed things down. I tried telling lots of people that putting fully changed blocks around new ones speed up the process. I seem to even remember hearing early on that the dev's said this was they way they worked, as the oxidization would spread from more oxidized blocks to less oxidized blocks more quickly. Everyone just ignored me and kept leaving all their blocks spaced way out. Thanks for proving I wasn't crazy. I guess I could have done work to prove it too, but, I don't have the patience for all the work you obviously had to put into this. Great job.

Speechless. Your content is VERY inspiring. Great work !

The 3rd Industrial Revolution will be inside Minecraft.

The excitement you have building these mega machines makes me excited! Cheers to both of you and your intelligence 🍻

Aww yeah, two m3 copper oxidization videos for the price of one! 😁 Very nice improvement, even though the powdered-snow-blockstream concept still is such a cool idea to me.

I'm just totally speechless about the work that went into this analysis...and I'm a math major. So well done. Bravo.

Amazing work you two 👍 Good video!

new cubicmetre in under a week? Hell yeah

too underated dude. Keep up the good stuff!

THIS FACTORY IS GENIUS!, you my fine sir have taught me more about redstone then 1000 mumbo jumbo videos AND I LOVE MUMBO VIDS

This is fascinating, thank you for sharing this.

Another amazing video! As always!

I have never seen your videos before. But I'd recognise that chest hair anywhere. Nice.

I suppose you could also set up a system to “recycle” the copper and eventually it would all become oxidised

Love how mans isn’t even salty he just did the math and accepted it.

rip the guy who built the old one in survival

I'm absolutely stumped , that someone outsmart in your field of Redstone ! Lol

3:57 The look on Albert's face in the second pic, after being let down gently by cubicmetre

5:34 reminds me of the electro-chemical potential in sacrificial anodes used on large ships to prevent their shit from rusting.

This feels like something that belongs on the SciCraft server. very technical and optimized, very cool.

I personally knew about the oxidized copper helped oxidize pure copper faster and the spacing helped out too, so I had been having copper oxidize on top of oxidized copper to have quite nice rates. I wasnt aware that more oxidized copper would mean an even quicker conversion.

your bot being called Ilmumbo and being half ilmango and half mumbo is just awesome

For the copper oxidation issue on the smaller farm, it could be possible to set so that if filters out oxidized copper into the shulker while the other variants just get sent back to the start

“Yeah that seems about right” - Sniper, Tf2

This is so precise high level engineering, I can't even imagine how long it took from 1st prototype all the way down to the last model

Click on the title, stayed for the maths, and build but confused on why or how I would ever build this in either creative or survival. First video of yours I've ever seen.

The conveyors of copper slowing down from 4GT to 4224GT and then speed up to 16GT is the most satisfying thing I ever saw in minecraft

Always making good videos

hearing cubicmetre say cubic metre is so funny for me for no reason

I don’t understand a word you’re saying but the background music is nice. Good job man thumbs up👍👍👍👍👍👍👍👍👍

Can I suggest that in the shulker box unloader, the hopper feeding into the bottom dropper is replaced by a dropper so that the hopper isn't locked by the observer, effectively extending the dropper line one block

if nothing else the "Block Conveyor Extender" design will be really handy for some builds

Extremely interesting video!

Dude, ive been saying this for the past year in Hermitcrafts comments section, lay out ur copper blocks, spaced out like normal, once it oxidizes completely just add copper blocks directly on top of the oxidized copper blocks instead of replacing them and boom, quicker oxidized copper blocks 🙂so yeah, this made immediate sense to me since iv'e been using this method for the past year in my MC world 😀

According to minecraft wiki you swapped the definitions of m. It should be 0.75 for pure copper, 1 for weathered and exposed.

im so glad that i can actually understand what he is saying

Damn, this blows my mind. I didn't expect people to make scientific and mathematics researches for optimizing minecraft factories. But now that I write this comment and now that I see this video, this absolutely makes sense xD But wow tho, really impressive work and great explainations ! I'm math teacher at math college in france and I would love to teach my pupils probabilties with minecraft applications. That would be awesome. Thank you for this video !

It reminds me of investing, you have to have oxidized copper sitting in place to get oxidized copper coming out

cool! also, this is an actual use for math. wish school had problems like this video

This is one of the best Minecraft videosi have ever seen 🏆 Instant sub

This man throws the word "extremely practical to build in survival" way too casually I love this type of videos but i can barely make a piston door, i wish one day I'm able to recreate this survival

i KNEW it!!! the single block modules with observer to auto farm would actually be better, if the area around that block is seeded with oxidized, now that ive heard the actual mechanics. BUT I CALLED IT, on a hermits video, i think Grains, where he had a sheet. i said he should seed it.

This is probably the only reason why my class mates learn math. To become the next cubicmetre and Mumbo Jumbo. I love Minecraft science. You just earned a new subscriber.

Mom: are you studying for your Math exam tomorrow? Me: wellllllllll

Very inspiring! Some thoughts that came to me about the original design: If you want to oxidize a "small" amount of blocks faster, the old design would be faster than the new one. My understanding is that the new one is faster if you fill above a % of the farm with new copper. Although I'm not trying to say that you would get higher rates, just that you could get your results faster, with less waiting. Unless I missed something? Then, if the copper checks around a diamond(octahedron) shaped area, it should be possible to get a denser layout by separating the blocks diagonaly from each other. Although the increased complexity might not be worth it.

i think a super dense pre buffer could solve the problem if you combine it with a long timer that locks out the imput while the buffer is full could make the small farm more practical takeing it from come back every hour to every 5 or so hours

The big difference is that your build can be built and be at full efficiency right from the start. The more efficient one needs exposed copper to already work

Man is too underatted wtf cmon at least give him a hundred k

I just build, I don't do redstone, but dang, can I ever respect the effort, skills and knowledge needed to make these kinds of things

@11:44 Ilmumbo? This episode is like a cross over between ilmango and Mumbo Jumbo! :-)

man i know il never be bothered to build anything like this in creative let alone survival, still awsome to see the full extent of people genius, wonder if termite farms wil lever be a thing once the wild update comes?

Meters? Seconds? Feet? Mile? NOPE! Everything shall be measured in G A M E T I C K

11:43 Ilmango + Mumbo Jumbo == Ilmumbo???

Great farm! Random idea: Would it be more efficient if you leave blocks next to fully oxidized blocks for a while, then blow them up to get the item form, then sort them by their oxidization state and then place them again next to blocks of the same stage?

Turns out the real oxidized copper was the friends we made along the way!

I like your funny words magic man

Great video

cliff notes for this vid: "you need oxidized copper to oxidize copper faster" XD

This reminds me so much of Infinifactory

This is like making a tilled grass farm (if you could pick up those blocks) but way slower

While I didn't care about the copper farm. I like the infinite extension of the piston feed tape. I tried to come up with it my self (for a vertical tape) for a long time. But I never really got into a lot of complicated red stone in the last 5 years so, So my design was slow and clunky. I really want to build an infinite long paternoster elevator for a very long time and now I can

For some reason the copper oxidization being sort of uniform reminds me of how ice melts. It won't get any warmer until all the ice is melted, in the same way steam won't get hotter until all water is transformed to steam. Unrelated, but interesting.

I wish I cared this much about my classes

i had a feeling it's better to mix in fully oxidized copper

Superb

wow ilmumbo in the house lol

What is nice is we can run a sb of copper blocks through the system, then just go afk at your copper farm for a bit, and repeat the process

Oh yeah, that makes sense.

Considering that the progress of oxidisation is random, I was thinking if it would be more efficient to make a farm that has a lower proportion of fully oxidised copper leaving and just recycling the blocks that fail to oxidise completely.

Ok, that is a very useful insight. More oxidized blocks nearby doesn't speed up the oxidization per se, but they offset the massive slowdown from blocks of the same level. If you only have a lot of blocks of the same level nearby, the chance to oxidize will be a very small number. If about half of the nearby blocks are more oxidized, the chance to oxidize will be about a half. Doing alternating sheets like this will about halve the oxidization rate compared to completely spread out blocks, but the density of copper blocks will go from 1/125 to 1/2. Sounds extremely worth it 👍 edit: Well, the fact that it doesn't oxidize at all if there are any less oxidized blocks nearby slows the process down further. Now almost all blocks must progress to the second stage before they can start heading to the third stage. Completely spread out blocks can keep going instantly. Still worth it though. edit2: Half the nearby copper being more oxidized doesn't halve the rate. It of course quarters it, because c^2 :]

Love the name Ilmumbo lmao

Talk about taking Minecraft to a whole new level.

meanwhile a sneaky minecraft update made copper waxing factory obsolete
