Redstone Comparator - Minecraft Block Guide | Properties, Recipe & Uses (2025)

What is Redstone Comparator in Minecraft?

A redstone comparator is an advanced redstone component that can be used to measure, compare, and maintain signal strength. It looks like a small stone block with three redstone torches on top. Its main purpose is to create more complex redstone circuits. It has two modes: comparison mode and subtraction mode. Players use redstone comparators to read the fullness of containers like chests and furnaces, to create precise clocks, and to build logic gates that are essential for any complex machine. It is a key block for any serious redstone engineer who wants to move beyond simple circuits and create truly smart contraptions.

How to get Redstone Comparator in Minecraft

You can only get a redstone comparator by crafting it. It does not generate naturally in the world. The crafting recipe requires materials from both the Overworld and the Nether. You will need three stone blocks, three redstone torches, and one Nether quartz. You can get stone by mining it with a pickaxe. You can craft redstone torches from one redstone dust and one stick. You can get Nether quartz by mining Nether quartz ore in the Nether. Once you have all your materials, open a crafting table. Place the three stone blocks in a horizontal row along the bottom. Place the Nether quartz in the center slot, and then place the three redstone torches around it in a U shape.

How to use Redstone Comparator in Minecraft

A redstone comparator has two main functions. In its default mode (the front torch is off), it compares signal strengths. It will only output a signal if the signal coming into its back is stronger than or equal to the signal coming into its side. If you right click the comparator, you switch it to subtraction mode (the front torch turns on). In this mode, it subtracts the side signal strength from the back signal strength. One of its most popular uses is to measure how full a container is. If you place a comparator facing away from a chest, it will output a redstone signal that gets stronger as you put more items in the chest. This is the key to building automatic sorting systems.

My Story

How This All Started

So basically, I was playing Minecraft one night after a long day doing deliveries, and I was trying to remember what drops what and how to craft certain things. Every website I went to was either dead slow, missing loads of stuff, or just looked terrible. I thought "bloody hell, surely I can do better than this?"

By the way, this My Story section is something new I've only just started adding things here! Most of the site was actually built before I ever wrote this part. Now that the website is live, I'm running into problems galore! So if things look a bit rough or unfinished, bear with me I'm updating and adding as I go.

That was probably a mistake.

A half finished story, oh well. I'll keep adding more as I go!

Learning the Hard Way

I knew absolutely nothing about making websites. Like, properly nothing. I didn't even know what PHP was. But I'm stubborn as anything, so I just started watching YouTube tutorials and reading random stuff online while I was on my breaks.

Turns out building a database is harder than it looks. Who knew? I've probably broken this thing more times than I've fixed it. My laptop has definitely been sworn at more than it deserves.

The worst part is when you spend hours trying to figure out why something doesn't work, and it turns out you missed a semicolon. Or when everything works fine on your computer but looks like complete rubbish on someone else's. Fun times.

The Reality of It

Look, I'm not gonna lie this has been a right pain sometimes. I work full time doing deliveries, so most of this gets done late at night when I should probably be sleeping. I've had way too many energy drinks and definitely not enough sleep.

The database has corrupted itself more times than I care to remember. I've had images that wouldn't load for no reason. CSS that worked yesterday but decided to have a tantrum today. The usual web development nightmare stuff.

But every time I get something working properly, it feels brilliant. Like when I finally got all the block images showing up correctly, or when the search actually started finding things. Small wins, but they keep me going.

What I Actually Want to Build

Here's the thing I want this to be your go to place for everything Minecraft. Not just blocks and items, but proper guides, build tutorials, maybe even schematics you can download. Server info, community stuff, the lot.

I know it doesn't look like much right now, and there's loads missing. But I'm working on it. It takes time when you're learning as you go and doing it around a full time job. But I'd rather take my time and do it properly than rush it and end up with something rubbish.

The plan is to make it the kind of site I actually want to use fast, easy to navigate, with everything you need in one place. No endless ads, no broken links, just useful stuff presented in a way that doesn't make you want to throw your computer out the window.

Why I Keep Going

Honestly? Because every time someone uses this site or gives me feedback, it reminds me why I started. I love Minecraft, I love building things (both in game and apparently websites), and I love the community.

Plus, I've learned loads doing this. Sure, I've wanted to give up more times than I can count, but seeing it slowly come together is pretty satisfying. And if it helps other people find what they're looking for without having to trawl through ten different outdated websites, then that's worth it.

So yeah, bear with me while I figure this all out. It's going to take a while, but it'll get there eventually. Thanks for checking it out, and if you spot anything broken or have suggestions, let me know. I'm still learning, but I'm determined to make this work.
