[@AL_O0]

I had a very similar idea a created a few years ago, it was a much more unnecesarily complicated setup but it worked with a tree-like structure rather than a start topology like this, very cool nonetheless

[@Terger17]

I'm really very grateful that there are channels like this to help all of us who don't understand anything about redstone, you're too smart a person, I don't think I'll ever be able to do something like this but as long as a tutorial comes out I'll know how to do it

[@jazziiRed]

My goal is to spread the knowledge of redstone to a wider audience. Most redstone channels are showcase-only and hardly do any teaching. Glad it's helping out!

[@TheCreativeType]

I think I had an idea like this once, adding names items that hoppers could detect to filter the shipments. Never build it though, but it’s cool to see that sort of thing has been done.

[@Gendreau113]

A idea I had while watching, was possibly replacing the "delay" with a comparator that detects when a item passes through that final hopper, as then regardless of how many destinations you have, the system will always automatically adapt to the correct length and never release the Minecraft untill the "stamp" passes through that final hopper that puts it back in the Minecart! EDIT: while that's a good idea, you would need some sort of timer anyways, just encase you receive a minecart without a stamp in it. Otherwise your system will hault and never resume... But still you could use it and potentially figure out a way to make it work into the system! Then it can save time for those stamps that have a shorter travel distance as you don't need to assume the longest delay for the longest travel length of stamp! Just a idea, but love your design of the whole delivery system!

[@NotBigSurprise]

i had a similar idea long ago, but i didn't quite manage to make it work really glad to see it fulfilled!

[@hw2007]

I didnt use your design because I really like designing stuff for myself, but this was a great starting point for my own version, as well as a nice video to come to when I was stuck on something!

[@BaileyChap]

I like the concept, and have a few compliments to make before I get on with what I did to change it: The empty carts being rejected into a pit is hilarious, and I love it! The overall simplicity of the design makes it's function very easy to follow. Giving players an alternative for different rail alignments is good. I couldn't seriously impove upon the buffer system, it's so simple and compact there wasn't really anything I could do, and the only change I ended up making was to mirror it to fit into a more compact position. Although I ended up making a few changes with mine, to make it faster, use less resources, and be more compact. I think I understand why you didn't do this in the tutorial, as it makes it more complicated, which would've made it harder to give such an easy tutorial for. I replaced the red circuit with a comparator that detects when the item has entered the last hopper, waits a tick, then sends the minecart, with a comparator count-down clock to act as backup in-case such item doesn't arrive, sending the minecart to purgatory. I minimised the use of redstone blocks where possible. The purple circuit is condensed to run within the main footprint of the build. The repeaters between the blue circuit and the main RS-nor latches can and were removed entirely. The pink circuit was modified to use alternating redstone dust and repeaters to make the system switch tracks faster. Buffer circuit comparator clock replaced with repeaters, which slightly speed everything up. Cart storage increased, and circuit moved to move compacted location.

[@Xavier-op3us]

I wanted something to build, and this didn’t disappoint me!

[@eliasalvarez295]

I had this tought a time ago in a server with my friends Built a main minecart line across 8 chunks or so, then we added a plane's mod and my rail network proyect became obsolete I feel happy to see someone made my proyect more complete, because what i had in mind was a simpler system Before a minecart would pass a switch joint, a comparator reads the signal from it. The chest holds just one ítem (shulker with things you want to send) and a number of ítems aside that indicates the strength that the signal from the comparator Will have. Then add a gate with a different signal imput for every house, so that, if signal Is false, the minecart turns arround and goes on in a circuit to the next base, if the signal is true, then the minecart goes on and reaches what was set as destination

[@Puffster]

I designed a mail system that used shulkers as packages. I also used paper and filters but the paper was injected into the shulker that contained the addressing info. Between each station there would be nodes that would check the address info and send the shulker in the correct direction.

[@dafoxboi6729]

Omg I made this same thing before too (except way more convoluted looking lol), although I added a way to hold packages if one was already being processed, along with a manual sorting room, where if an address isn’t found within the system, then it can be sent down a separate line and processed manually by someone and sent to the correct address. I should make mine look more clean like this though idk how you do it so well, mine is so much messier 😭

[@llynxfyremusic]

I actually built a modular design like this a few weeks before a friend sent me this video. I've used some elements of this design to improve my own and i think i've actually improved on this concept quite a bit. I'll link the youtube video when i've finished it.

[@stephensterling1874]

I had the idea for this exact thing a little over a year ago and my friends told me that it was impossible. The main problem was the unloaded chunks. I guess I'll try it out now.

[@zwatotem]

There is so many cool projects with minecarts, redstone and other things that you could do in Minecart, but the fact that active redstone or moving minecarts don't load chunks makes a lot of them obsolete. I wish they had a gamerule to allow for this, so that public servers can prevent abuse and severe lag, while small private servers can enjoy the utility of projects like this one. A need to build a weird portal contraption everywhere is a sign of a flaw in the game design in my opinion.

[@rebornreaper194]

This is really clever. However, one request (tip) -- before doing a block-by-block tutorial, I would recommend going over the major components in your design. For example, saying "I used an item sorter here to do X, chained to an RS nor latch array component to do Y, etc etc." With the reasoning. At least for me, that would help me a lot in getting an idea of your design & design process. :) Cool stuff! Thanks for sharing

[@jazziiRed]

Ok, I'll keep this in mind for the future. Thanks for the feedback!

This looks like a Switch yard. A good one

[@AnimilesYT]

8:27 To elaborate: The hopper doesn't necessarily need to point into the comparator. It can also point to the back. The thing that's important is that it does NOT point into any other hopper or any container. If it's difficult for you to aim at the small edge of the comparator then you can put composters on top of the first hopper line you built and then aim the hoppers into the composters. It is theoretically possible to get a working filter with those hoppers pointing into each other, but this is diffiicult to get right. It also requires unique filter items (or uniquely named items) for the filters to work. This is because the hoppers want to put the stuff that's inside of them into the thing it points into. So it can point into any container, as long as the container does not have any free spots left. But this is a bit too complicated and detailed for in the video, so pointing it into the comparator is always safe :)

dude what the heck?! this is awesome btw!.. but yo, i wanted to create this same thing but as a train station to go around my world. have u built one? i had the idea of using serial data lines and registers, each build in the world would have an id, and u select that location from home station and the cart takes you there. i love your switching mechanism! so cool, all of it!

[@Oscar_Garrido]

Great videos man, im planning to combine your telegraph with the postal service so I dont have to include a key

[@jazziiRed]

Sounds like a great idea!

[@henrycgs]

it should be relatively easy to make multiple districts, right? it's just a matter of having one post office per district and two sets of stamps (one for people, one for dsitricts). every district would know only the stamps of the players living in there and of the other districts. so, if you are in District1 and want to send a stamp to Player10 in District2 you just add a District2 stamp along with the Player10 stamp. the minecart would go to the District1 post office, get sent to District2, and that district's post office would send it to Player10. you could even have multiple layers of this (one stamp per layer) and eventually have "international" logistics. probably the railway between larger stations should be more robust, with multiple channels, to avoid collisions. this actually sounds so cool. and I really wish I could do that in the game... but I don't have enough friends for that to be practical, lol.

[@_MrStick]

Tips: build cactuses beside the stop points and hoppers underneith so you dont need to break it if you want

[@ivoknoob_2909]

I made a few months ago automated mail machine wich uses shulkers and needed money to work (1 Diamond). Also uses hopers or water strams to deliver the things. Maybe your design is more usefull, but i will make tutorial for mine machine

[@demp11]

16:50 you can also just break the other rail, place the curved one and than place it back

[@mr_pigman1013]

cool

[@nihel3144]

22:15 wouldnt it be more reliable to make the last hopper activate the rail? it could help prevent any possible issues with desynch that could arise from the server lag and make the whole process slightly faster, especially for a larger scale system.

[@charliedoesgaming4701]

I have spent a couple hours now figuring out why the dispensers won’t put the items back into the bottom dispenser. Is it because I’m on bedrock?

[@jazziiRed]

Yes. If you are on Bedrock, I believe you would have to replace the slabs with full blocks.

[@turnerdeedo4633]

LOL. I invented nearly exactly the same thing two years ago. It works almost exactly the same way but it's even simpler. Minecarts come in, the stamp (i called it a card) gets removed, and the cart gets sent on the correct track. Mine was simpler, faster, and more expandable however. All carts enter on one line (like yours) then get run across a bunch of modules. Each module is the same. It contains an item filter, and simple redstone mechanism the flips a switch. The switch is timed so it changes just as the cart moves over it. If a cart somehow bypasses all of the modules (could be caused by a malfunction) it gets recycled back through. Carts that switch off the main line get routed to the correct outbound track. The cards get kept by the system so that you can have players pay for the service. Due to how it's built, the cart never stops moving and it is infinitely expandable. I'm not saying your design is bad. I'm just giving you advice on how to improve it.

[@jazziiRed]

Oh, that's a pretty nice implementation! The beauty of redstone is that there are many different ways of achieving the same end result, and unfortunately not everything I design will be fully optimized. Thanks for the comment tho

[@turnerdeedo4633]

[@megaing1322]

As an alternative to the long delay mentioned around 22:00, wouldn't a simple falling edge detector on a comparator for the hopper facing the minecart be possible? I guess a very small delay there would also be useable instead of a edge detector. This has the benefit that it means that no minecart has to wait longer than needed, and it without changes scales to any size.

[@jazziiRed]

Yes, that could definitely have been done instead

If the memory bits (Pink circut) won't reset, Place a row of blocks above the other row turning it on. then, place a line of redstone on it. Power this redstone line to reset it.

Only issue is that you’d have to restock your own Minecart chests

[@Umbraminf]

you could make a way to "recicle" them by sending back an empty Minecart chest with only a stamp when you receive one, and actually using one of the bases (G for example) as the post itself, so you can address the post. The letter cemetery cold also store the items in the chest and then somehow put it back on the dispencer? Or create a "waiting line" of minecart chests Edit: But you still have to retrieve the stamps by foot, I'm no good with redstone, so I don't know how

[@Ganpan14O]

I had an idea for a similar system (that I'll probably still make) that would basically be a decentralized version of this system that uses a big 2 lane rail loop

[@Ganpan14O]

I also had an idea for an automated store using this system, which I'll make regardless of if I make the other system, just expanding your system if I don't make my idea

[@An_Average_Cuber]

THIS is only an issue if a minecart is sent while the pulse extender is on! I could not get the buffer to work, then I realized that the dropper that does not have the comparator coming out of it shouldn't get powered when the pulse extender is still on. Added a little circuit and now it works.

[@marckiezeender]

I wonder if this can be modified to make automatic railways. I.e., to transport a player to a predetermined location via a piston bolt. I imagine it would require 2 minecarts in succession, one to carry the stamp(s) and one to carry the player.

[@yousofhariri]

Hello! if i want to do this across a large distance but low destination server, where would I have to place the chunk loaders?

[@jazziiRed]

Yes. Video on this coming soon ;)

[@henryk2380]

personally, I dont think sending the stamps to the receiver makes sense. I would send stamps from the smaller offices to a the central one (assuming there are multiple), then collect them in a chest so server members can occasionally pick up stamps they sent away/need. someone mentioned there is no way to prevent collisions because of silmultaneous sending and receiving, this could be solved with another buffer of some sort

[@jazziiRed]

I can see that, yeah. I mostly saw it as a way of confirming you got the correct parcel. You can also rename the paper to send it back if you want. But yes, I understand what you mean

[@kylegillman3572]

Very amazing design but I am having a slight issue with the buffer system. When far away the minecart gets stuck in the buffer system above the fence gate, even with a chunk loader. This could be a server issue as its on Aternos with some friends but Im not sure how to fix it.

Also I play singleplayer so who am i even sending to (yes i know i can use this to transport items in bulk to different areas of my base, should my base grow too big in size. Which would actually probably be helpful in my mines, I don't use shulker boxes so it might be cool having systems like these rigged up).

[@jackstrawn8133]

I am curious, does the gate being pulsed open in the way that it is allow for only one minecart to fall through, even if multiple minecarts are sitting on top of it? Seems like a potential flaw, but I'm not an expert by any means lol

[@jazziiRed]

Yes, only one cart falls through at a time

[@tristanvanvalckenborgh4817]

In this design are 2 big problems. What if for example person a sends a minecart to person b. And person b sends a minecart to person a? Then the minecarts will collide and no minecart will reach its destination but just bounce off eachother and return from where they came. And if there is only 1 central post office it will deffenetly jam and malfunction when multiple minecarts get send into it.
