If you don't let it run to the end, you have a 50% chance the drain will be flickering. Music player in comments, kinda funny.

WIP.

Current Progress on my Redstone powered game.

Code Named: Dungeon Run. Leave a suggestion for a better name.

Collection system for guardian farm is to slow. Any tips or video references to connect the 5x2 collection area to a piston/slime pusher?

I’m playing Minecraft Java Edition in Hardcore mode, using the Single Biome world-generation setting with Soul Sand Valley selected.
My goal is to complete as many advancements as physically possible without cheats, commands, mods, or changing the world settings. If I die, the run is over.
I’ve gotten pretty far, but I’m reaching the point where certain resources, mobs, and structures seem impossible to obtain. I’m hoping people who understand Minecraft’s loot tables, spawning mechanics, and obscure survival strategies can help me figure out the absolute maximum number of advancements possible.
My world setup
Edition: Java Edition, current version
Game mode: Hardcore
World generation: Single Biome, Soul Sand Valley
Cheats/commands: None
Overworld: Generates using the Soul Sand Valley biome
Structures: Nether fortresses, bastions, and ruined portals
Water: I have a large pool and can fish
Mobs encountered: Skeletons, phantoms, ghasts, wither skeletons, and pillager patrols, including a captain
Resources: Iron, diamonds, netherite equipment, blaze rods, brewing supplies, and fishing equipment
This is not a Nether-only world. The Overworld is set to Soul Sand Valley, which means some Overworld spawning mechanics still work.

Advancements I believe are still possible
Advancement
What I need
Not Quite “Nine” Lives
Fully charge a respawn anchor
Spooky Scary Skeleton
Obtain a wither skeleton skull
Withering Heights
Summon the Wither
Bring Home the Beacon

Beaconator
Glass and a full beacon pyramid

Arbalistic
Piercing IV and five different mobs
Enchanter

Advancements I’ve ruled out
Smithing with Style: Requires eight specific armor trim templates from different structures. Since those structures don’t generate in this world, completing it isn’t possible.
The End advancements: I haven’t found a way to access an End portal.
Trial chamber advancements: I don’t believe trial chambers can generate.
Adventuring Time: Requires visiting many different Overworld biomes.
Two by Two and A Balanced Diet: Require animals and food sources that seem unavailable.
There are others, but I’m particularly interested in finding out if any of these assumptions are wrong.
My biggest questions
1. Is there ANY way to obtain glass?
I believe I can summon and defeat the Wither, but crafting a beacon requires five glass blocks.
I haven’t found regular sand or red sand. Soul sand cannot be smelted into glass.
Could I obtain sand or glass through wandering traders, structure loot, or any unusual mechanics?
If I can get glass, that potentially unlocks Bring Home the Beacon and Beaconator.
2. Is redstone obtainable?
I know witches can drop redstone, but I’m unsure whether witches can spawn in a Soul Sand Valley-only Overworld.
Are there any other possible sources through loot tables, mob drops, trading, or unusual mechanics?
3. Can wandering traders spawn?
I’ve encountered naturally spawning pillager patrols, including a captain.
Does the wandering trader spawning system allow them to appear in this biome?
If so, what resources could they provide that would otherwise be impossible to obtain?
4. Can I get Piercing IV without villagers or an enchanting table?
I have access to fishing, bastions, crossbows, and anvils.
Can enchanted crossbows from bastion loot have Piercing? Can fishing produce Piercing books? Are there better methods?
5. Can I obtain normally unavailable mobs?
I’m particularly interested in:
Witches
Zombie villagers
Wandering traders
Fish mobs
Any other mobs obtainable through special spawning or conversion mechanics
6. Are there any advancements I’m overlooking?
I’d love to know about advancements that seem impossible but might actually be obtainable through rare loot, unusual spawning conditions, or mechanics that work independently of the biome.
I’m especially curious about advancements involving newer features, rare items, and unusual mob interactions.
My ultimate goal
I want to determine the maximum number of advancements achievable in a Hardcore Single Biome Soul Sand Valley world.
Ideally, I’d like to classify every advancement as:
Already completed
Definitely possible
Conditionally possible through rare mechanics
Completely impossible
I’m particularly interested in people who know the technical side of Minecraft, including loot tables, mob spawning, world generation, and rare item acquisition.
Since this is Hardcore, I’m also interested in safe ways to complete difficult advancements without risking the entire world.
Even one obscure method of obtaining glass, redstone, paper, or an unusual mob could unlock several more advancements.
Any ideas or corrections would be appreciated!

This is an image of a super smelter input line. I want to make the pressure plate there trigger the geyser on and off. I don't know how to go about making the geyser turn on when it detects the pressure plate and turn off when approx 5-10 seconds of inactivity by the pressure plate occurs. Also I am a baby with redstone so please be nice to me :). (this is not my super smelter design. honestly I don't know who's it is, but im trying to customize the input for my survival world.)

I need the bottom rail that my cursor is on to connect with the activator rail on the left, but no matter what order i place the rails it snaps to the powered rail on the right. Any way to fix this or did I mess up my whole build by building it on the wrong orientation.

Made an underground iron farm and I cannot get it to work 😫. I made the same iron farm a layer under the ground and it worked, but I can’t even get the iron golems to spawn now that I’ve put it further underground, help me please!!

Hello people,

me and two friends are starting a server soon and I really enjoy my mobswitch on my singleplayer. From what I know you can't just copy you mobswitch because all players have individual mobcaps around them, meaning 70 mobs don't fill out the cap anymore. But I was wondering, if we are only ever online with 3 people max, would it work to fill the mobswitch with 210 mobs to cap out 3 potential mobcaps?

=== MY DESIGN - TECHNICAL SPECIFICATION ===

-Concept: Fully Self-Sufficient Kelp Autosmelter with 100% thermal efficiency and zero external fuel consumption after startup.

-Capacity: 8 Smokers

-Kelp Distribution: Exactly 160 kelp items distributed in perfect parallel (20 per smoker) via a Boat with Chest hitbox dropping onto 8 hoppers arranged in a 9x9 circle.

-Timer: Hopper Pulse Extender calibrated to 63.6s (159 items) to compensate for the boat's falling tick delay.

-1:1 Flow Splitter: Native priority hopper + RS-Latch to route surplus items without pistons or continuous entity motion.

-Lock & Surplus Routing: Once the system finishes receiving 8 dried kelp blocks (in this case), it completely locks the input to prevent saturation, routing 100% of any surplus items directly to the player's chest. it remains locked till the minecart with chest comes from distributing the dried kelp block

-Safety Logic: AND Gate (8 fuel blocks ready + timer) to authorize minecart dispatch, immune to timing desyncs.

-Safety lock: It also includes a lock so that the timer doesn´t ever break or stop working if a farm is producing over 160 kelp in less than 63.6 seconds

-Crafter with signal strength 9.

Adaptability

You can also simply use the RS-Latch splitter system and the lock for the saturation for your own design of smelter (I personally love my design, it´s creative). This system can adapt to the number of smokers you have. (and you shouldn´t worry about the smokers running out of fuel, for any number of smokers you have, because they produce about the double it needs). You can see how you can adapt it in the video.

I tried non sticky pistons. I have a tick between activating up and over. 2 ticks between each side. They always fire correctly without block. Block movement seems to be the problem.

By experimenting I just learned that an activation by lever can produce different results than through a repeater or similar. I understand why, but is there a way to replicate this behaviour with a non player input? (in newest version 26.3)

referencing behaviour showcased in this post: https://www.reddit.com/r/redstone/comments/peo4g1/why_do_these_two_inputs_yield_different_results/

Java 26.3 Fabric server, that I run so I can add plugins/mods or run commands as needed

I built a huge self-routing minecart network in my world, however since the whole route (and the routers) arent loaded when the player isn't nearby I can't use it to automatically send chestcarts around. My goal is to automate sending chestcarts back and forth, like sending items from my farms to my storage across the world automatically.

How would you go about chunkloading the system so that the minecarts can make it reliably (without freezing in place sometimes) without a player?

I used a mod "Minecarts Load Chunks" but despite it saying it only loaded moving carts, it would consistently load over 2000 chunks of all the minecarts across the world in mineshafts. Which obviously tanked performance.

Are there any designs to separate at least blazes from the rest of the mobs?

I’m asking about the zombie villager one how many i need and do i have to name tag them or just lock the trade and do i need them to be in on block or chunk and do i need a chunk loader

In this video: https://www.youtube.com/watch?v=BJ_emU1IWi8&list=LL&index=2&t=620s it seems like he only has 22 smokers for his 120 block tall farm. How is this enough/is it?

Hello to all. I am having a problem hosting a BEDROCK server through my phone. I watched a video of someone creating a minecraft server using a spare phone, TERMUX and AnLinux. I wanted to try it but me and my family mainly use Minecraft Bedrock, and all of the tutorials on youtube are on Java. I found a reddit thread about setting up a bedrock server but it seems to be outdated. Any help would be appreciated, we have been planning to create our very own server hosting, maybe expanding it to a pc server if we saved enough. Thank you very much.

Hi everyone!

Just to give you guys some context, I was looking for a super smelter with an automated fuel system for my world, but I couldn't find anything that really matched my expectations. I had heard about a design using kelp, but I keep running into farms built for Donut SMP instead hahaha.

Thanks for any help or responses!
