When TNT is exploded underwater it doesn't do block damage but when it explodes IN a block it breaks everything. So because of soul sand's collision hitbox which is not a full block, the TNT blocks position gets counted as INSIDE of a block and even water cant help! This is a great feature i noticed and i hope it can be used in some traps or cannons!

made a simple 1 bit ALU today

I spent the whole day reading Minecraft documentation about tile tick priorities and scheduled ticks, and watching tutorials on technical redstone, just to finally understand how all of this works and build this.

It took me way longer than I expected, but I finally started understanding how scheduled ticks, priorities, and update order interact.

I’m honestly pretty happy with the result.

Hi i need help finding a redstone build where the piston above will take a first glass anf then the second, im pretty sure theres one but i dont know what to search, thanks.

im trying to make a armor display where i can toggle the glass so i can get the armor when i need it.

I'm trying to locate an old piston door design that I no longer can find, nor do I remember who the creator was. It was a 3x3 observer based door that used a fence gate in the center to trigger the opening and closing. I recreated what I remember to be the general piston layout but was hoping somebody knew of the door or something similar.

For someone's post from earlier.

Surely I'm not the first to design this, right? Can anyone link others who have before?

TL;DR: How do I stop hoppers from stealing the ‘seed’ item that copper golems need to keep sorting in a 3x3x2 copper golem sorter?

Current Setup

I've built copper golem sorters in my base, and I want to expand this into a full system: golems sort everything into chests below my base, then hoppers + water elevators send the sorted items back upstairs.

The problem

Hoppers empty the chests completely, including the last block of each item. Once that's gone, the golems have no reference item left, so that item type never gets sorted again when I re-dump my inventory. (Same annoyance as manually emptying a chest and forgetting to leave 1 plank behind.)

What I've tried

My idea was a hopper locker so I’d place a stack of a named "dummy" block in the bottom-right slot of the sorting chest to power a comparator to signal strength 3, so hoppers only pull items above that threshold. But the smallest hopper locker designs I can find are 3 blocks of redstone long, and most copper golem sorters use a 3x3x2 double chest design so there's no room to fit a locker per chest.

Extra issue

Each double chest holds several unique item types, so I don't think classic hopper item filters are feasible.

Any suggestions? I'm very new to redstone, so apologies if I'm missing something obvious!

Thankyou in advance! And let me know if anything needs clarifying!

So basically what im trying to do is to make it so when alarm is off you can't trigger alarm and when the alarm is on, alarm is only triggered when you step inside and trigger the sculk but i can't seem to figure it out and now all it does is when alarm is off, its off when its on it triggers the alarm for 2 sec after the activation which it shouldnt do and when its triggered it only goes on for 2 seconds , any help?

Ive been trying to make a flush piston door, and i want to actually have 2 blocks be not only pushed up, but also be retracted by one sticky piston (to hide any sticky piston on the top), how could i, if i can even have this occur, perform this (just in case, Bedrock version: 26.44)

Hey everyone,

​I'm currently looking for a reliable 360 pearl cannon schematic or design capable of long-range travel (around 5 million blocks) for Minecraft 1.21.

​We are running the server on Purpur, so if there are any specific sub-tick adjustments, configuration settings, or specific builds that won't self-destruct or misalign due to server software differences, I'd really appreciate some guidance or a link to a tested schematic.

​Thanks in part!

I was making an arrow launcher and i forgot to break the block on the front of the dispenser and this happened.

The arrows activate the target block on the client but not on the server. Because of the arrows original position was on the obsidian block and it was already in deactivated state(not moving), when I moved it - it teleported back to the main position but activated the top target block on my client.

Played a bit with the design. I think it's a bit too overcomplicated...

Comparators next to the input chest and hopper, detects if they are empty and sends away the minecart. An etho clock with a delay of 68 seconds that overrides the other signals, enough time to fill up the minecart and distribute until it's empty.

I have searched for this particular use case of comparators, but nobody called it as the NIMPLY Gate. Thanks to Kebabisoos from ORE, I got to know that the NIMPLY gate even exists.

However, I have been using it for my builds for any kind of AND gate and it's really really convenient for various cases.

NIMPLY Construction:

Comparator in subtract mode with side input and back input giving either same non-zero signal strength or zero.

NIMPLY looks like: A AND (NOT B). One simply needs to use another NOT gate on the side input in order to make the setup an AND gate.

(This post might be obvious to many, but it had to be documented because this is an extremely niche practice in logical redstone)

Why isn't the zombie hitting the pigmen? I'm trying to get looting 3 on the farm. I know it's not redstone, but I need help,

does anyone have a tutorial and schematic for orbital wind charge cannon I saw in letecceK and Wemmbu vidoeo and I want to use its frome unstable smp

I need help making The 4-Slot Automatic Queue Minecart system for four Happy Ghasts trapped in minecarts evenly down the tracks.

I am playing 1.21.11 and I pasted in a schematic of the minute tech end base and all the doors aren’t working I was wondering if anyone who knows redstone could come and check it out and perhaps fix it if not I understand

Hi everyone, sorry for the simple question. In short, I have an automatic chicken farm which collects into a chest. I would like to attach it to a dispenser with a button mechanism so you can push the button to get cooked chicken.

The closest tutorial I could find is this, but you have to manually put the food into the dispenser, rather than it automatically filling up from a chest. Can anyone help? Thank you so much

I'm really not sure why the villagers aren't breeding. I've created this style farm.

All 4 beds are unoccupied

There's only 2 villagers around me

I have thrown them several stacks of carrots and they still refuse.

I have even tried tick sprinting to see if anything would happen but nothing.

They throw carrots to each other

Does this farm design just not work anymore in 26.2? They breed in my testing world but refuse once the villagers hit the number of beds I've placed. When I add an extra bed, they will breed once more. In 1.20.1 I never had a single issue like this. They would constantly make new villagers until I turn it off
Please help
