New Slime Farm Selfsubstainig
Idk i just wanted to put it out there since this is a new concept(i think)
it is really simple and shoud be scalable (it is really laggy) I alrady buid it on the donut smp so that isnt a problem.
The Slie generate new Silverfish wich die and generate new slime. This scales expodential

Minecraft 1.21 - Self-Reactiving Chunk Loader (No Manual Reset After Reloading the World)
I noticed in my 1.21 world that when I left, all my chunk loaders stopped. I had to restart them each time.
So I created a chunk loader that activates automatically with an armor stand equipped with Frost Walker boots. When the player enters their world, the armor stand generates and freezes the surrounding water. The observer then sends a signal and reactivates the chunk loader.(I accidentally deleted my post, so I'm reposting it.)
Latch with Timeout
I came up with an interesting solution for a niche need I had and thought I'd share.
This is a dropper latch that will timeout if not flipped back and thus flip iteself. When the piston (regular) with the RS block is pulsed, it flips the latch and turns the lamp off, this also starts the countdown via the hopper clock. If the other piston (regular) does not receive a pulse to reset the latch externally by the time the hopper runs dry, it will flip itself via the observer looking at the rails powered by the comparator reading the hopper.
Usecase:
I'm using this as box detection and as part of a system recycler circuit in my redstone factory. When a request is made to restock a crafter with items this latch is flipped. When the output is off 4 pistons retract that control various different components in the system. When the requesting slice receives a box the latch is flipped back and the next request is processed. Should a box never be sent do to no stock or some error, the hopper clock is timed for the longest it should take to restock the furthest crafter. When it runs out the latch flips and an alert is turned on that a request failed, but the next request is still processed so that the system doesn't come to a halt do to 1 item being out of stock.
SANDBRIDGE: Make floating sand/water bridges in vanilla minecraft
Playing with sticky pistons to make falling blocks float, and a flying machine that will help speed up building bridges made out of these blocks that really shouldn't be floating that way
PSA: ALWAYS surround your carpet bots with blocks
Not even a joke. Had a world eater running with 4 carpet bots loading the area. The 4 carpet bots were on 3x3 platforms above the world eater. Desert biome (meaning no rain or thunderstorms at all). Our server has phantoms turned off. Meaning there is literally nothing that can kill or move the bot and the platforms are also way too high for endermen to randomly teleport there.
I was busy at the storage system when I get a notification: "Player loader3 was blown up" (or something like that).
I immediately rush over to the perimeter and behold... it broke. Going to the platform where the bot was, I saw a skeleton horse standing there instead of my bot. And the skeleton horse was not in the trap state anymore since nothing happened when I got closer.
The only theory I have is the biomes being 3D since 1.18, a part of the platform where the bot was, was a river. I did check on the ground level and I remember the platform would have been over a river biome, but I moved it to the side a few blocks (checking that the 3x3 area is desert), but since the platform was at something like y200, I assume the river biome was maybe on one or 2 of the platform blocks, allowing lightning to hit there and the getting unlucky and it spawning a skeleton horse.
After a lot of head shakes and laughing and being angry-confused, I decided to just surround all the bots in blocks and respawn the bot. Fixed the world eater and have not had any issues since then.
Also this is fabric 1.21.11 with standard tech mods and xaero maps.
So TLDR: Always surround your bots in blocks. No matter what or where.
Made my first raid farm...
Java, 26.2, long time casual (very casual, no automatic farms) bedrock player. The redstone in java is much better so i wanted to give it a try while also getting into the core mechanics of minecraft. Saw This Wattles Video tha looked promising, ended up being terrible. Actually, every farm I've made from youtube so far has needed major tweeks for it to be effiecient, but anyway, this raid farm is killing me.
After Placing 18,000 buttons then realizing raid mobs still spawn on buttons, I decided to redo some of the farm. My platform is at y+63. At Y=54 I have one villager with a job block bed, and a bell that rings every second to get the attention of the raiders.
This was a big improvement, but mobs are still spawning farther away, not on my platform, which makes sense because I did not spawn proof properly. What I don't understand is why they keep spawning but not heading towards the center of the "village." If it is too far, then why even spawn them there in the firs place? I have exited and reloaded, hit them indivisually, ran away, exited, reloaded, nothing seems to work. The only thing that could aggro them is if I hit them, leave the game, and join back. This works, but as soon as I run away again it;s like they're AI just turns back off. This is the second time it has happened at this location, but it happens at other spaws aswell. The only thing to ever attack me when I get close are vindicators unfortunatley.
I undersatnd I could make a new, better farm, and I probaly will, but I want to know why this happens and how to fix it. I originally thought itg was entity culling but it seems to be the actual A.I. Itself
Last picture is my perfectly sqaured farm layout. As said early, it is sitting at y= 63, raiders fall in a whole leaving them wityh 1/2 heart, then I finish them off.
Recreating components that requires quartz
Assuming you dont and never will have access to the quartz, what is the limit of technical structures that you can make?
Can you create a component that mimics the observer or a comparator, with redstone or any other material rather than quartz? Is it technically possible?

Help with my iron farm
Can someone help me my farm is only spawning iron golems in one side of the villagers room it's working but way slower than it should be. There are no golems outside.

Items skipping hoppers
I'm having issues with items continuously skipping hoppers in my sorting system. In this clip I was testing the skip rate for the last column of chests in the system. I have them properly aligned with honey blocks at each corner, so I'm guessing it has something to do with the random momentum given to each item by the bubble elevator throwing the timing off? If there's any quick fix I could add to the top of the bubble elevator that'd be great since I'd like to keep it
I've done a couple of tests to figure out the skip rate. With 10 stacks of mixed blocks there's about a 0.8% skip rate over any given hopper, and with 10 stacks of a single item it goes up to 3.4%
Here's a link to images of the clock I'm using and the corners of the water stream: https://imgur.com/a/KgdmsvF
Why Can Spiders Still Spawn Here?
This seems to be a pretty common question, but I haven't been able to find a solution on other similar posts. Why can spiders still spawn in this farm? I've tried a few different layouts of slabs/trapdoors to block off any 3*3 spaces, but spiders keep clogging up the farm no matter what I do. Am I missing something obvious?
is there a difference between the books that librarians trade at different levels?
I noticed that librarians have a chance to trade enchanted books at 3 different levels of experience - are these trades all the same, or do the books get better as they level?
Is it possible to automatically feed a composter?
I have so many veggie farms so I put stacks into the composter, but it can take a while right-clicking it. Is it possible to automate this process?
[Bedrock] Why was my production so low after 7 hours? See desc. for details
I have an iron golem farm setup with 20 villagers and I always occasionally see two golems spawning when I pass by the farm as I’m playing so id assume it’s set up properly. I also have 5 tamed cats by the villagers. I went afk overnight for ~7 hours and this is all it produced. However I set my simulation distance to 8 chunks so I could afk my gold farm at the same time. I didn’t necessarily look at the chunk distance but I know I was exactly 100 blocks away from the center point of the iron farm the whole time. My gold farm is silentwisperers 4 portal one that produces a lot of piglins so maybe that’s why? Idk any insight would be appreciated.
Do iron farms work in forceloaded chunks?
I have a server (godlike) and I’m wondering if iron farms work in forceloaded chunks? Since the removal of spawn chunks I figured this was the next best choice. If so, do zombies have to be bobbing instead of stationary?
Did an update break simple iron golem farms?
I have been building an iron golem farm for around two weeks at this point and it doesn’t seem to be working. After around 1 day I went into a creative world to start over there and I’ve made it a few times. I have checked that there’s no caves, no villages nearby, and exactly 20 fletchers with beds, but nothings spawning. The design I’m using was made by ModStop and it’s pretty simple overall with people in the video’s comments saying that it worked at least 9 days ago. If anyone understands why this may not be working or has another farm that they’ve seen work in the newest patch for bedrock, I’d love the help because I’ve run out of ideas as to why it’s not working.
Why automatic farms stopped using the trident killer with the new 1.26 update?
I have noticed that since the 1.26, some farms that automatically kill mobs dont use the trident killer anymore and instead use this system of a mob with spear in a minecart like the one in the picture (Which is a screenshot of a video tutorial for a creeper farm).
What is the reason behind this change? What are its advantages?
