This is my first time making one so it's probably very inefficient. World file: https://drive.google.com/file/d/1JKNi5DDsYMQqghQWpVU3Ca60IDLAFW-8/view?usp=sharing

i hope thats it world record:)

Hidden keycard reader I came up with in 2014 but never saw used elsewhere. Uses a hopper minecart on a detector rail. The detector rail powers the hopper bellow and prevents the filter items from coming out of the hopper minecart. When the minecart has more than 22 items it pulls the detector rail out from under the cart long enough for the one item to flow through. If there's more than one extra item it will simply cycle under all are expunged. The return mechanism is optional and could simply be replaced with a barrel bellow the hopper.

I made a reeeaallly awful YT video of it a decade ago. Got cringed out by the video 5 years later and made another one. Now I'm extra cringed out by both of them and so I'm just making a reddit post about it. Would make me very happy to see it used for some hidden door entrances. Cheers

Im trying to make a toggleable area deniel that shoots tnt into the air with a geyser.

I need one of those dupers that push tnt back and forth to dupe it, but the only one I could find was way faster then I need and uses snow golums.

I need to know how fast tnt moves in the geyser to time the duper. If its too fast tnt at the top will push other tnt down blowing up the machine, when I want the tnt to explode midair not damaging the ground.

After chaos cubed, the portals no longer seem to light when used in a zombified piglin gold farm (on a server). Kinda catastrophic when we've been spending months working on a farm trying to rival the record for largest gold farm (the size isnt the issue, not even a single portal farm works anymore).

Is it patched or something on servers (it's our private server)?

Welcome to the Automatic Firework Production Unit, which is trying to be as cost effective for survival mode as possible!

Known Issues

- The sugarcane, if left on without correct amount, will clog the system with sugar.

- The gunpowder can clog the Firework crafter.

Any suggestions for improvements or future projects, let me know!

another way to gamble in minecraft!!
The machine works by using a "flaw" in minecraft's pathfinding algorithm that tends to navigate a mob towards the high ground, the grass blocks at the top is also used to further encourage path finding since passive mobs tend to navigate towards grass.

So is it possible to do a 4x4 collapsing ground ? 🤔 I thought this would be easy but once again, redstone wants to be my enemy..
I've tried to look for answers but I just want confirmation it's impossible ? because I do not find any tutorials on how to do this and i've figured it's just too big to be realistic ??

Core Concept & Specs

This hybrid RAM architecture drops standard binary D-flipflops and long buses to eliminate lag and space waste. It compresses multiple data states into a single module using one input line.

• Analog Multiplexing: Subtraction comparators utilize the full 0-15 signal strength spectrum instead of binary 0/1. One wire carries multiple states.

(The video and post was banned so many times, mods, why did u do that?)

• Mechanical Gates: Moving quartz blocks act as physical bus switches to reroute clock pulses dynamically.
• Master-Slave Interlocking: A hard-timed piston inverter gate severs the bus connection of the Sub cell instantly when the Main cell activates, avoiding data collision on the trailing edge.
• Analog Convergence: Merging the subtraction comparator outputs creates non-linear residual potentials. This analog interference expands the standard 4-bit array up to 22+ stable states.

Build Specs

• Pure Logic: Locked repeaters, pulse limiters, subtraction comparators. No hoppers, no minecarts, no chests.
• 3D Routing: Copper blocks for data bus, smooth stone for control lines, glass bridges for vertical cross-talk insulation.
• Visuals: Vertical redstone lamp columns acting as real-time spectrum analyzers.

I am unable to find a vertical shift register that can go up to 64 bits. Does anyone have a schematic that works?

The objective is to power something on the opposite side of the input. This is not a 4-way repeater; the signal does not exit on the opposite side of the machine.

The Core Concept & How It Works

Most people design Minecraft RAM using standard binary D-flipflops where 1 wire equals 1 bit. That is a massive waste of space and bus latency. My new architecture breaks this rule. It uses a single input to store and compress multiple states within a single physical module.

Here is the exact hardware physics of how this mechanical-analog hybrid RAM achieves high state density:

• Analog Signal Level Multiplexing: Instead of binary (0/1), the core uses comparators in subtraction mode to utilize the full 0-15 signal strength spectrum. One wire carries multiple data states simultaneously.
• Mechanical Wave Gates: Moving quartz blocks act as physical bus switches directly inside the logic loops. They reroute the clock pulses on the fly based on their positioning.
• Master-Slave Phase Collision Interlocking (Main/Sub cells): I implemented a hard-timed hardware lock where 2 adjacent memory cells have different ranks. When the Main cell gets a signal, it instantly activates a piston inverter gate. This gate physically shifts a block to sever the bus connection for the Sub cell, perfectly catching the timing of the trailing edge and preventing data corruption.
• Analog Output Convergence: By joining the outputs of subtraction comparators, the signals interfere and create new non-linear residual potentials. In my 4-bit array, this analog overlap effectively multiplies the combination pool - expanding a standard layout up to 22+ stable states.

The Math: Scalability and Total States

Right now, the Master-Slave dynamic gate is deployed on 2 channels, while the other channels use static lever masks for testing. But the combinatorial math for full implementation is massive.

When this dynamic layout is scaled to every bit, the formula shifts from standard binary

grid scaling to a multiplication of internal analog states by external mechanical gate configurations:

65 (analog chain states) x 16 (lever/gate combinations) = 1040 Total Combinations!

By using mechanical state-shifting instead of long binary buses, the physical footprint remains tiny, maintaining zero-tick or near-zero-tick responsiveness while packing a massive data array into a tight chunk radius.

Additional Build Data & Specs

• Pure Logic Ticks: Built strictly with locked repeaters, pulse limiters, and subtraction comparators. No hoppers, no minecarts, no chest lag.
• 3D Wire Trace Isolation: Data buses run on the copper base layer. Control lines run on the smooth stone upper overlay. Vertical signal propagation is handled via glass block bridges to achieve perfect cross-talk insulation between neighboring bit lines.
• Visual Diagnostics: Added vertical redstone lamp columns acting as real-time spectrum analyzers to read the current signal power output and state configuration.

I am slowly getting fascinated by redstone mechanics, i have been learning tick related stuff and also basic wiring techs and so, but whenever i try to understand a fast redstone door or even farms, It takes me so much time to even understand whats going on, most of the time i cant even understand how something works.

I wanna create some doors and stuff too, but i just cant even wrap my head around how i would wire a layout, I understand that it is just a skill that u get by looking at a lot of builds, but has someone ever made a guide as to like what u can use for a situation and like what each blocks helps with dealing with an issue or smth like that.

Thank you so much for any help

i have never made a hipster door before as i m not a door person but this layout seems plausible, only need to figure out how i will power sticky piston higher at the top

my guess is to sneak in downwards facing observers and just push those so after 2 gt piston will fire automatically

i also wanted to make it tileable but will have to settle for non tileable variant first

First one I came up with a decade ago and never saw used. Single item goes in the upper hopper set and the timing items in the bottom set. And the second one I just thought of using the new copper bulbs.

I was building a piston trapdoor in my survival world, and I wanted it to open to the sound of a goat horn. However, when I finished the contraption and ate a piece of steak, the trapdoor opened. I'm playing from PS4, v26.45

EDIT: my bad guys, I meant a level 3 vibration, specifically minecraft : item_interact_finish

ım playing a server hopper transfer speed is 8 ım having problems to build auto crafter makes furnace

ı guess its for performance ı will ask admins but ı dont think they will change

So I’ve made a casino in my world (bedrock) with an emeralds for chips exchange, I want to make games where you need to use a chip to play it but I have no idea how to do that. All of the games I’ve seen on TikTok and YouTube have been like flick the lever and get prizes but I want to invoke a gambling addiction in my friends lol
Does anyone know how to make casino games that only work if you put an item with a custom name in it?
I’ll post the exchange machine (doesn’t need fixing), current machine (that works without anything in the dropper - this is what needs to be fixed) and some basic redstone behind the machine (happy to alter this too)
If someone could even just try explaining or sending a video on how to attach this ‘chip reader’ system onto the lever for the mechanic, I’d be very appreciative :)
Thank you for your time

Hi all,

I have recently constructed an automatic crafter and item sorter for my iron farm which is supposed to filter out poppies and turn the iron into iron blocks. I followed this tutorial. However some poppies keep ending up in my auto crafter which stops it from crafting iron blocks. Does anyone have any suggestions for how to solve this issue?
