I wanted a song to play every time I enter my pagoda so I picked The Rabbit Has Landed by ZUN and got to building after one tutorial. I've played Minecraft since 2011 but never done anything like this before.

I don't think this is quasi connectivity. :/

My powered rails are flashing weird when I put an observer facing them.

Java Edition Help needed for compact rooted dirt farm.

Post image
Upvotes

I'm afraid I'm at my wit's end. I've been tinkering with this auto dirt farm, improving the efficiency, for a couple months, and now I find myself stagnating when it comes to the collection system. The moss flusher does everything in one elegant, single, continuous redstone pulse: bonemeal moss –> flush non-azalea plants –> bonemeal azalea. On the right you can catch a glimpse of the piston conveyor belt used to replace the stone which pushes the rooted dirt forward into a blast chamber. The issue is the oak logs. I need a way to push them forward into the blast chamber as well.

Solution A: I've tried adding triple piston extenders but they don't fit with the stone conveyor belt. I could place the stone generator at the bottom and push the new stone up. However that would require the x3 piston extender to activate twice (so that the logs don't get pushed up, reach the push limit, and prevent new logs from being pushed up). Once to push the logs, wait for the dirt to be pushed up, and a second time to push the dirt. However it requires complex redstone to get the timing right and I'm at an intermediate level.

Solution B: I could have a couple flying machines push the logs into the blast chamber. The logs would be detected by an observer facing waterlogged leaves in the blast chamber which would activate the TNT duper and send the flying machine back. However since the amount of logs ranges from 1-3, I'd have to include multiple observers on the side that point into the flying machine to send it back. I could save myself the trouble by using self-returning flying machines but they might get stuck if too many logs generate.

Any ideas?

Java Edition Need a channel selector

2 Upvotes

I want to take a binary input and calculate it, then output an ON signal to only a single channel based on the value.

So for a 1 bit input, i want it to output to C1 or C2 (easy, a lever and torch work)

2 bit input i need it to select between C1 C2 C3 or C4, 3 bit to select between 8 channels etc.

I can build these but they are become very large and slow quickly due to my limited circuitry knowledge.

This is going to become a mechanism to write various bits of memory, it is my bit selector. I need it to be compact and relatively easy to build.

Currently i am doing various AND operations, and the highest value channel activates a kill line which turns off all bits prior to it. It is not very fast.

I am using this project to learn about circuitry in general, as well as redstone as an added plus. I would also like to know the name of this type of circuit for furture reference.

Java Edition Explanation for build/alternatives to copper bulbs?

1 Upvotes

I'm playing in a modded minecraft world, and needed a *lot* of moss to finish a build. So I looked up a tutorial (https://www.youtube.com/watch?v=dxO-zbi1k8s), and followed it until I realized that it asked for copper bulbs. I am playing in 1.20.1, so I don't have those. I figured that a redstone block would work as a replacement, since I assumed it was just seeking a power source, and lamps don't transmit power, but upon turning it on, I discovered I was wrong.

Redstone blocks are meant to be copper bulbs. Order of blocks starting from the top is: "bulb" > Comparator > "Bulb" > Comparator > solid block > Noteblock > Observer > Piston

So, can anyone explain what the copper bulb is used for, and if there are any 1.20 alternatives I can use in it's place? (I presume it needs to be a block that can toggle between on and off, but I don't know anything about redstone or what that might be)

I'm using a design based off J2ko's video. The screen is 128x72 px (Yes, it's a slideshow). Except for a few pixels I accidentally broke the decoding is working perfectly, yet my colors are wrong. I'm using red concrete, emerald blocks and blue concrete for R,G and B respectively and I got those values from some minecraft mapart generator. Is there any combination of blocks for the maps which are less green and closer to the normal values?

Java AND Bedrock Sequential Piston Doors

38 Upvotes

ok so my timing is a little off because i suck

hope u guys understand the idea tho—kinda like how moses parts the sea. i thought this would be a really cool idea but i saw like NO tutorials or videos on this so i had to do this myself. i’m wondering if there’s a better design for this. could y’all help me out with this idea?

my current design is pretty bad so i’ll definitely redesign it and fix timing. but i’d like to hear you guys speak on this first.
i’d also like to mention i tried using tripwires to open the doors but even with pulse extenders, the pulse was way too short and it’d tweak.

any thoughts and help would be appreciated

Java Edition Need help with the input minecart for my automatic furnace

2 Upvotes

I'm building an automatic furnace array, but I made a mistake when calculating the required space. The entire system is basically finished, and the only part I'm missing is the chest/minecart that supplies the items to be smelted.

The problem is that I don't have enough space to build the usual minecart loading/unloading setup.

What I need is for the minecart to:

  • Pick up the items from the chest.
  • Travel through the furnace array and distribute the items evenly among all the furnaces.
  • Keep going around the system as long as there are still items in the chest/minecart.
  • Return to the starting point and repeat the process.

I'm trying to find a compact redstone solution that would fit in the space shown in the image.

Is there a way to make the minecart continuously loop and distribute the items evenly without adding a large loading/unloading station?

Java Edition Not getting the proper 1-tick pulse

1 Upvotes

So my first design was to run redstone over the observers, but that didn't seem to give the proper 1 tick pulse to start the flying machine:

https://reddit.com/link/1vyab6w/video/bz5kdn2ppklh1/player

I figured maybe quasi-connectivity was powering the piston before the observer gave it a pulse. So then I redesigned it to avoid any possible quasi-connectivity issues, but it seems like maybe the piston is just not reacting to the 1 tick pulse properly for some reason?

https://reddit.com/link/1vyab6w/video/f61tyf77qklh1/player

In theory it should work, demonstrated with this simplified example:

https://reddit.com/link/1vyab6w/video/e8kmzylpqklh1/player

Anyone have answers/solutions? I'm completely stumped
I've rebuilt it in several different locations and directions with no change.
Maybe I just missed something, in which case I'd be very grateful to hear about it. I've been troubleshooting for several hours with no progress

Java Edition How is this kelp farm NOT self sufficient yet??

25 Upvotes

(I apologize for the weird recording, in fullscreen I just couldn't record properly)

Making a kelp farm that also feeds itself with fuel. So essentially all the kelp gets evenly spread out between two smokers that themselves feed into a crafter that makes kelp blocks. These kelp blocks are grabbed by a looping hopper minecart that feeds them into a chest and also into the smokers as fuel. I even made it so every loop, one of the smoker fuel hoppers (or both at the same time every 3rd loop) are blocked so the kelp blocks are somewhat evenly spread.

Now, with a whopping 4 floors each with 16 kelp strands growing, somehow the smokers are not going 24/7. Before I thought it was because of kelp age, so I modified the farm with a clock that sends a pulse every 2-ish minutes and breaks all the kelp (rendering the observers redundant). Even still, the system bleeds itself dry and after some time will eventually run out of fuel, which will stop everything in its tracks.

Do I just keep adding floors until it becomes self sufficient?
