So I was having the same problem as a lot of ppl that have commented on here. If more than one item entered my hopper at the same time, the elevator would lock up on the first two droppers. I did find a solution to the problem. Not sure it will work for everyone, but I figure it's worth a shot. All I did was run redstone from the torch under the bottom dropper to the side input of the comparator, and viola....problem solved. I'm guessing it has something to do with the difference in the signal strength from the torch and the signal strength coming directly off the dropper, but I'm just beginning to wrap my head around the more advanced mechanics. All I know is, once I hooked up the side input the comparator now updates for every item in the dropper until it has pushed everything along. I am using the single elevator and playing on PS4 if that makes a difference.
Matthew Adams Thanks for the solution, same problem (PC version). Couldn't wrap my head around it. Thanks again!
+PacificBoya sorry for the comment on an old comment, but I saw that several people used your fix to correct the issues with this awesome build. Could you show more completely what you mean?possibly a video or picture of what you are doing?
thanks dudde!
Xisuma used this tutorial in his latest episode of Hermitcraft. Good Job Draykke.
AngryKnine Thanks AngryKnine; long time no see :P
Draykke Devry
LOL Yeah. I'm still around here and there :P He butchered the pronunciation of your name, but linked to your video :P
Yeah I noticed that haha :D
That Design is the best I've ever found - silent, simple and resource-friendly to build, and not a single item gets stuck. I am playing on 1.8.6, PC version.
Best explained item elevator tutorial yet, thank you!
I don't comment much but this time I must! Outstanding contraption! It got hung up as others have described on my first stress-test but works great now. Def subbin!
Well done sir! Fantastic design, quiet, compact and yet truly expandable. Cheers
Hope it serves you well :) Be sure to check out the other content on my channel as well! :D
Awesome design, thank you so much!
today i tested your contraption and it worked better then i thought it would , very well made dude :D awesome work
Awesome tutorial bro, just starting playing minecraft a week or two ago and the time you guys take to do videos is very much appreciated. Thank you :)
Wow thanks a lot man :) I'm glad you liked it and welcome to Minecraft :)
Be sure to check out the other content on my channel as well (tons more tutorials and LOTS of Let's Play)!
Just used this design on my slime farm. I was trying to use a different design featured on Mumbo's channel, but it kept glitching out. This one is working perfectly so far. Thanks!
Thanks man, what an awesome design! Love it
Thanks so much man. Been looking for an elevator that worked and I finally found one.
Everyone seems to build these Dropper Item Elevators solely around using the Comparators as the sole input choice for the clock, which pulses the torch tower and turns on and off the Droppers. This is great, however it doesn't address the very real situation in-which; if there is more than a single item inside the "ignition" Dropper, which is the first Dropper, then the whole "clock" which is designed to get it's "ticks' through that first Comparator, will stay in the ON state. This stops the clock because the clock is no longer receiving its "pulse' inputs from the Comparator and in turn, breaks the system.
I have seen quite a few reputable Redstoners on youtube fall into making this simple mistake..
Quickfix: Create a clock system which isn't dependant on the Comparator's "pulsing" output and instead, dependant on its "ON" state. Since it's irrelevant whether the Comparator pulses or stays on, in regards to the clock, since the clock will only require an "ON" state, whether thats a quick pulse or not is irrelevant.
big thumbs up! perfect design, simple & it works very well! great job!
konstantine walters Thank you very much! :D
Hey Dude! After 6(!) Videos I saw about vertical item transportation... yours is the first one that really works! HALLELUHA! You saved my day! Thanks you! Pretty cool tutorial! :D
What an awesome design. Thanks so much for this.
This is a REALLY great system, thanks so much for posting this! Every other design that I've tried can only take items one at a time, which is really impractical for the farm that I'm using this with. Thanks Draykke, keep up the great work!
You're absolutely welcome! And yes that's all I found when double-checking this online (too make sure no one else built one similar) was single-dropper elevators that transport one-at-a-time; and of course you could use multiple of them but it would be so bulky so I developed this lil' guy :)
Great video. This is very simple and effective. I tested it using a bulk of items thrown into a chest to feed into it and everything made it to the top!
As it should good sir! I hope it serves you well :)
Great work man. It's way better than my elevator that I used.
You've got yourself a new sub.
Awesome :) Welcome aboard and prepare for the mind of a mad man LOL. Make sure you check out my Let's Plays (WARNING IN ADVANCE: Tons of mature content.) :D!
Nice video. You are good at tutorials. You speak clearly and you are easy to understand! You just earned a like!
Buster Pie Thank you very much :)
Buster Pie Yeah but talking too much
Buster Pie Yeah but talking too much
Thanks for this. Works great!
Thanks! Very helpful, first one I've got working on my smp server.
You're welcome :) Be sure to check out the other content on my channel. I have tons of other tutorials, my Redstone for Hire series, and my Let's Play series' (WARNING: Lots of mature content). :D
Thanks for the tutorial. I was wondering why hoppers couldn't just be used, thanks to you, I have the right way to go about this.
well i did see on youtube many itemelevators , but this is mindblown recourcelight and awesome . well done , i was looking for such an elevatordesign for a really long time . You saved my day :D therefore i subscribed and i hit that likebutton :D
Thanks a lot man, your sub/like means a lot to me :) Make sure you check out my other content too, maybe you'd really like my Let's Play (WARNING: Lots of Mature Content)! :D
ok now i have a task for you >:D could you build a drawbridge which has a width of 5 blocks? full out of redstone and as compact as possible? that would help me out a lot and additional there should be a portcullis also in that construction . for medieval castles and so , if you know what i want to have :D
peter radinovic Oh boy, that's a tough one :) I'll mess around with the idea for a bit sometime and let you know if I come up with anything. Unfortunately now is a really bad time for a Redstone For Hire request because my schedule is REALLY packed.
that would be very nice :D
Really nice design! was fiddling around with a double barreled elevator but couldn't figure it out, was getting to used to redstone with command block. + 1 like
Really helpful. It works perfectly with the item storage silo I use that requires the items to be dropped in from the top and I didn't want to have to go up an entire level just to put items in. Without it I would have to walk up a staircase or climb a ladder every time I wanted to put an item into storage.
Worth mentioning that normal large chests cannot be placed side by side like that, *however* trapped large chests and normal large chests can. The only downside is that the trapped half of a three or more tower tends to interfere with transmission if you're too trigger happy with opening and closing the input chest.
Specifically, I noticed that trapped models will not feed the input as well as not accept feed on the output if it's open on either of their respective ends. Undoubtedly the constant signal given off by an open trapped chest is to blame. And material seems to build up in the center of the tower if either ends are interrupted.
After working some more numbers, it's a poor storage solution considering blocks stored per cubic meter. In a double tower model, it's only holds about 40-45% of the material compared to stacking regular chests on top of each other. But it was meant as a transport instead of a storage solution, and even still a double tower about 15 blocks high still stores 300+ stacks in it's system. A double going from diamond level to sea level would be able to store over 1k+ stacks in it's system easily.
I was curious and tried using Ender chests, but they don't take in or output material from droppers and hoppers. If they did, it could potentially infinitely loop material in a system, providing a constant stream of material to any further placed Ender chests. That would eradicate the need to bring along building material to any new locations; take a single Ender Chest with you and have access to dozens of stacks of material whilst taking up only one inventory slot. Sadly, it doesn't work.
Lastly, a modification to the design can be made to clear out debris in a double without inputting more material. A clock can be attached to two repeaters leading into the side of the bottommost redstone torches of the tower, then the clock can be toggled by a signal controlled by a lever.
Aside from that, this is a great multipurpose design. I recommend a double tower installation for moderate mining operations/strip mining alongside a service chute for maintenance in survival. The 3+ models seem a little excessive for most mining operations.
Amazing, thanks Draykke! Since each block up in the torch tower adds 1 tick delay, this can go from bedrock to build height! Oh and because it's SILENT, I used one in my hidden, silent cooked chicken farm! (I credit you in my tutorial)
FYI if yours stops and fills the bottom dropper, you MUST have only 1 hopper pointed sideways into the dropper and that hopper cant have another hopper above it pointing down. This causes items to go in too fast and the comparator jams the timer. If you change the timer from Draykke's design, it gets bigger and may stop being silent.
If you're having problems at the top, try making sure your tower uses an odd number of droppers (the top of the torch tower will have a torch facing the top dropper) If you have to, you can point the last dropper sideways, or feed a double chest and hopper off it.
works awesome! this makes bring items up from the mine sooo much faster! thanks for making this video!! :)
Absolutely :) Thanks for the sub! Be sure to check out the rest of the content on my channel too! :D
Great elevator! It's really cool, that it's silent. But it's a little bit slow. But i doesn't matter. Good job!
Excellent design Draykke, I have a single row elevator handling eight of Nim's iron farms without a problem :D
Great job, works nice!
I like it, but will add glowstone blocks to the front for visual effect:). Loved the original build, but this is definitely a step up. Keep it up Draykke! Liked/already subbed.
Finally it is working for me. As long as I use droppers instead the dispensers. I was wrong at the begining. Great Job!!. Thumbs up!!. Greetings from Spain.
Thx helped a lot for my op prison shop i am making :) since we only have 1 layer of dirt then there is bedrock so i had to find a way to bring items up :) THX
I love how Jumbo made one of these the same way and before this guy lmao XD
Im not a red stone guy but this may come in handy for my sorting system that im "attempting" for factions, i actually found you through looking at factions videos :)
Haha that's awesome :) Most people find me through my tutorials so my Let's Plays don't get as much love as I'd like them too :/
Hi, the problem on those designs are, that if the upper chest is full the elevator could be stuck. I've found a design which is still compact (5x2) but nearly always reliable:
for 2 layers you need:
- 2 dropper
- 2 hopper
- 2 comparator
- 3 redstone torch
- 6 blocks
odd/bottom layer (seen from "above")
dropper->comparator->block->redstone-torch->hopper(facing other hopper)
airslab(to avoid somethings falling into the hopper clock)
redstone-torch
Wow thanks mate, new subscriber :)
Absolutely :) Welcome aboard good sir!
Draykke Devry Haha you're welcome and no thank you :3
I like that it's compact, but I have issues with overflow. If the top container fills up and it carries down the line then the entire thing will stop working completely if the feeding dropper receives 2 items in it. Is there a work around for that issue?
Hey @Draykke, any improvements on this to make it work on multiplayer?
This is by far the best and most efficient elevator out there on CZcams that was amazing and the fact that it's expandable vertically(not very useful for me) is a lot to imagine you've got a new sub and you should have more! However i do recommend getting a recording system like fraps which doesn't have a watermark but other than that you're a perfect commentator and your content is useful and well edited. Thanks a lot! :)
Glad to have you on board, and yes the watermark has been LONG gone (Still use Bandicam because it's amazing), also upgraded to Adobe Premiere Pro for editing.
wicked :) better than most i found and still working in 1.8 thanks Draykke devry
Absolutely good sir :) Toss the word around! :D
can't get this to work. hangs on first dropper. 1.9
Late but I have a solution :D. Just put redstone next to the torch under the dropper and the block with the comparator
This is really cool!
Glad you like it :) Be sure to check out the other content on my channel as well (WARNING: Let's Plays have mature content) :P
is there something I'm doing wrong when building this? this is quiet a simple concept but anything I'm dropping in it is only reaching the second or third dropper they don't really get all the way up unless I try and fill it with items
I tried using this to send items into a sorting system, but found that I couldn't get it to feed into hoppers. The blocks or rs torches activate, and lock, the hopper I have my dropper tower pointed into. Unfortunately, I'm limited in space vertically, so I can't add an extra double chest on top of the droppers to then feed into my sorter.
Any ideas?
couldn't get the top dispenser to feed into a chest but works great. work around i used was to turn the top one on a side and have it shoot into another hopper chain
I love how simple and compact it is, the only thing I don't like is how much slower it is than other designs.
i want to use this for an item sorter so would it work with single items (without the other items pushing each other up)
Had issues on vanillaverse on making this dropper work with more than one item being pushed to the first dropper at a time, but I did find a work around, I'll attempt to post a video up of what I did.
Nice one! It's super easy for me (as a upcoming redstone professor) ;) Thanks!
+IAmRedstreet Absolutely! Best of luck professor :P
Excellent ! Fast and efficient :) have two very tall ones so far transporting minerals out of the depths of my mine to the sorting rooms :) Works as advertised on the tin :)
Mystic Virgo Thanks so much for the kind comment :P
thanks yeah its a good system :) I had been using one of Mumbo Jumbo's systems but found it clogged so I had to add a 'pacemaker' circuit. yours no bugs or clogs :0
Mystic Virgo Gotch' yo back! :D
I had a problem where the items would just sit in the input chest and the first couple of droppers, but it seems fixed once I took everything out and broke and replaced the comparators. I think it might be due to the fact that I accidentally built it on a chunk boundary.
That is so flippin' cool :D
Glad you like it :)
Wonderful design! It's much better than Mumbo's dropper design. It's working for me on an SMP server in 1.8.1. I love how simple it is and the fact that it's silent. I will say for those having problems that I'm using it to transport and deliver lava buckets for smelting, and it's possible I'm avoiding problems because they're non-stackable items. Anyway, thanks Draykke Devry for sharing this design. I'm going to show it in my next LP episode and I'll be sure to link this tutorial. =^)
Thanks so much for the comment :) It's nice to see replies like this that are written well and show appreciation for the system.
Also thank you for providing appropriate credit in your LP video; that means a lot to me :D. Good luck w/ your series and I hope that it serves you well!
I have noticed that this design can effectively “clog” every so often the hopper tube just needs to be cleared real quick manually but beyond that works like a charm
not sure if anyone is checking this video or not, but when the dropper gets more then 2 items the whole thing stops. As someone else pointed out it could be lag or dropper/hopper timing.
Either way if you add a pulse to the comparator on the bottom dropper it will turn off which will cause the items to flow resetting it. I am still trying to figure out something better or more to the point better looking.
Just found out that the horizontal design does not work with non-stackable items. The comparator ends up powering the redstone dust that goes to the bottom torch (hope this makes sense).
It's not working for me. I built the dual elevator for my item sorter. It works for a couple minutes and then suddenly breaks. The lowest droppers start collecting more than one stack at a time and then it all just stops working.
Do I need it to be a chest at the top? I'm currently feeding the dropper tower into hoppers because I didn't have to build it as tall that way.
I kind of like the older 3x3 design better, especially for even numbered droppers.
Once you get the wiring at the bottom out of the way the rest of the tower is pretty compact. I also like that it sits flush with the surface at the top and bottom so you can cover everything up with a floor and does not require going deeper than the hopper for when you cannot dig down.
Great design! No need for glass elevators anymore
Thank you so much man, I finally find a elevator ! and it works !!! :D
Absolutely :) Hope it serves you well!
of course it serves :D
I’m building the dual elavator, when one side is on and the other isn’t it makes noise. Is there anything I can do to prevent this?
Awesome elevator. The only thing is that when you put a bunch of different items in at one time, a lot of them get stuck in the top dropper once all of them are out of the bottom. I've had close to 100 items stuck in that top one at one time. Any solution for this? Maybe a way to keep the elevator powered for longer?
so i have an afk cobble/ore generator that i will do like 2 hour sessions on... i will put a weight on my mouse and literally just walk away. my question to you is if i can do a 3 wide item elevator with 3 rows of droppers right next to each other? or do i need to space them out for the red stone to work correctly?
the afk gen is on a server, the ip is play.evopvp.net, and its in skyblock. ores are able to spawn from cobble generators i'm trying to think of a design that will work...
In the double design, the second tower gets stuck if you insert a non-stackable item. e.g., put a pickaxe in the first hopper, and it will get to the top without problems. Put it into the second hopper (of the second tower), and the system gets stuck, at least the second tower.
thanks for the great video.
Sure thing! :)
Verifying that the single dropper version works in 1.10.2 PC, is dead silent, and handles stackable and non-stackable items. Combined with a no-step-down water transport, this will get your stuff anywhere you want to move it. Not quick, but low resource. Very nice.
Skip to 5 mins in to ACTUALLY WATCH THE TUTORIAL
works like a dream, auto farms are now hooked up to auto sorter.
Best and most stable elevator, EVER!!!!
MANY THANKS MAN
okay i make it like u did but when i put items in my elevator just on goes up and blocked at the second dropper and the rest stay in the first
Very good item elevator it works for the 1.7.2
it works when storage above still have space. but It doesn't work anymore if the storage above are full. anyway to solve it?
Tried it and it still works in 1.19.2. Quiet, too!
Hey Draykke, I have a question. How can I get the bottom dropper to send an item up if it gets trapped? This happens if I /home, /shop, /return, /back, /tpa, or just happen to walk too far away from my base at the wrong millisecond/second. Is there a way I can get a constant pulse on the bottom dropper that doesn't cause any issues? I suppose I can play around with it and try to find a solution. If you know of a way to fix this though, I would very much appreciate your advice. ;)
It's very much needed because, if an item gets trapped on the bottom dropper, the hoppers leading into it will get backed up with items. I don't want to have to go and manually take the stuck item out of the dropper every time this happens. It makes leaving my base a real pain in that arse if you know what I mean. I would rather have an automatic fix that clocks to this, so I never have to worry about it again. Not to mention, I have a lot of farms that I set this up to, so the chances of it happening to one, even multiple dropper towers at once is very high. >.>
It's not just your design either, this has happened with other dropper towers I have tried before this. This only happens when I leave the area too far. Especially when I do it with commands. If I stay in my base, I can be in there for days (literally days in real life) and an item never gets stuck. Unfortunately, I'm having the same issue with Etho's Hopper Clock. If I leave when a piston happens to be extending or retracting, the items no longer move from hopper to hopper, and stay stuck in position. Then I have to go and take them out, and put them back in to reset it which shows me this same issue applies to a wide variety of builds. >.> I feel like a prisoner to my own base.
Yes unfortunately you've run into a long-standing bug in Minecraft to where if a player loads out of a chunk (say, travels to the Nether) and then loads back into the chunk, it will cause a slight lag spike/latency issue that can interfere with Redstone projects. Item elevators, as you've experienced first-hand, are one of the main systems impacted by this.
Unfortunately, there is not a solid fix for the issue. The only way you could fix it would be maybe to hook up a daylight sensor to a redstone clock; so for example, when a certain time of day was reached, the redstone clock would turn out and send a BUNCH of redstone pulses to the item elevator that would move the items through the droppers, thus unclogging them. This would be the only way to fix the issue without having a 24/7 redstone clock running (because that causes excessive lag, especially on servers).
Hope that helps you bro! :D
This is a great design, and really compact, and I'm now using it in some of my builds where space is really tight. However... it's not the fastest design. The torch the bottom dropper is indirectly sending a signal into the hopper, which blocks it from feeding items every other "cycle". The fix is to have a slightly larger footprint at the bottom. Remove torch at the very bottom and have a signal feeding back into the comparator (to make it pulse while the bottom dropper contains something) and feed current Indirectly into the bottom dropper (making sure the feeding hopper will not be powered). Also sure there is a one tick delay somewhere in the comparator clock circuit (e.g. with a repeater) or the torches in the tower will burn out. This will make a dropper elevator that is at roughly twice as fast at the cost of a slightly larger footprint at the bottom.
While this is true, the signal is fed into the hopper for a reason. Not only does it make the design more compact, but it limits the amount of items being fed at a time. I built it this way as a hopeful fix for the "clogging" of the elevator that is so prominent with every other design (including my old one).
So it's kind of a sacrifice of speed for reliability in a sense :)
Tbh ... if you want speed .. stack it sideways, 8 elevators should be the max you'll ever need and have 8 inputs into a doublechest that you can access from the bottom, should be the fastest way to move items up if you're in a hurry,
Or if like me have several thousand deoublechests in a storage system, feeding an industrial sized smelter And need to send the fuel back up to the machine from the bottom of the storage.
Speed isn't the issue since you can have multiple elevators working simultaneously.
im confused as to why not just have a tower of torches on blocks so (block, torch, block torch) vertically next to droppers and have a redstone pulser (minecraft betapulser so its infinite even when you log out) and that would power the blocks above the torch adn turn on and off normally? this seems really big if u ask me ecause of the tower
Multiple reasons:
1. A continuous redstone clock can cause a lot of lag for people, especially on servers (redstone clocks are No-No's).
2. A torch tower built that way would be much slower than this one, because it would move the items one-at-a-time up the elevator, rather than a straight shot up like this tower is.
3. A tower like that has a high potential of overall bugs/glitch-ness; due to the mechanics of it, multiple items could get stuck throughout the tower without moving on; even though a new redstone pulse will move those items upwards, the next item will get stuck. This means the elevator would not be 100%.
thank you :D
Got a small problem with the 1 item elevator.. It seems only to work with 1 item. if i add a stack it stopts at the 2nd dropper..
Hey draykke great elevator I'm on Xbox one and have come across an issue, it works well for a bit but for some reason it stops so when I look into it I see 1 item in the 1st dropper and the rest of the items are built up in the first hopper into the dropper any ideas? I clear it out and then try a few items and it carrys on jamming up??
Yes unfortunately this is a known Minecraft issue - If the player reloads or leaves a chunk, the redstone in the area could suffer a very short delay. In that short amount of time though, systems (such as this one) can jam up. The dropper elevator works by moving EACH item through one-at-a-time as they come in, so when 2 or more get inside the dropper the entire system locks up.
I actually might try to make a self-correcting dropper elevator if I get the time to do so; one that will unclog itself if this glitch occurs.
Draykke Devry a self correcting setup would be amazing, i love your design
anyone who is getting their items stuck in the bottom elevator in online servers. Run redstone from the torch under the first hopper, to the very first comparator and that will fix it.
i used the single dropper elevator on my witch farm, but once I increased my spawn rates, the single dropper couldn't keep up so i switched to your double-dropper design. after about 10-20 minutes the torches burn out and it stops processing items
Are there any known glitches to building elevators in the nether? I've tried four separate models, including yours, and the items inexplicably shoot out the sides of the dispensers almost as if they are being squeezed out.
Are you using dispensors? If so then that is the reason. These are Dropper elevators - if you're using droppers then the "shooting out the sides" should never happen.
And no, building in the Overworld or the Nether doesn't effect the redstone mechanics.
if it's transporting only one item, to fix that just invert the signal with a redstone torch and it will be fine ! Thanks Draykke ;)
@Erin Henderson
Once the item enters the dropper, is the comparator picking up on the item and sending around the redstone signal to activate the dropper?
+Draykke Devry Yeah, Tricky.
+Draykke and anyone else interested. If you're building in Survival mode there's a much simpler (ie less likely to fall off it), less redstone-torch heavy way to build this. Use the droppers as a central tower and build a spiral staircase of blocks up around it...that way you only need one torch, positioned on the side of each block so that it's below the next block up in the spiral. I don't do video but there's a pic here...
It is not as expandable...but then I don't see why you need several item elevators side by side anyway?
Stick a clock on the bottom block or use your comparator trick and it works just the same...
+Nigel Coxon WAAAYYYYY more efficient
Hey Draykke, I love this design and it works perfectly on single player, but I have a problem: I play on a multiplayer server in which hoppers seem to run at 7x speed. Every tick they load 7 items into the container they're attached to. This unfortunately seems to break this elevator.
Do you think there would be a workaround for this?
Unfortunately I don't think there would be. :( Sounds like either server lag or they've modded hoppers in some way.
The system get stuck if you go far and come back, there should be a comparator to reset it if something is left in the first dropper
It doesn't tile if you are using each one for a different system/item.
If the chest up on top is full, will the item it is taking u just spit out and go everywhere? Or will the redstone just stop?
+WEATHER2DAY From what I could tell, it splits the material evenly between the two droppers underneath the output chest.
I'm getting a problem where the bottom dropper will not send up any of the items that go through it, I've triple checked that I have both torches, the comparator, and the redstone placed correctly. I double checked that they are droppers as well and I have no idea what might be causing it to fail, any suggestions?
I honestly couldn't tell you without actually seeing how you've built it. If you'd like, you could send me some screenshots through Facebook and I could take a look at it.
this design WORKS from the bottom to the top of the build limit in multiplayer..,perfect for my tower! but,I tried adding an automatic nether wart farm using water to push items into it, & it stopped elevating items at the 2nd or 3rd dropper upwards. is this a stack amount input issue? and if so is the double dropper design a way to correct this issue for good? thanks, and btw, despite my prob its an elegantly simple build to make! thanks :)
You're welcome :) And no, the design is never limited by the amount of items that it has to move. The only thing that will cause this system to fail is multiple items entering the bottom dropper AT THE SAME TIME.
This can sometimes be caused by server lag, or if not enough RAM is allocated to the Minecraft.exe client. Typically this doesn't happen, but if it does, I would look into those two things. You might also find adding additional hoppers to move the items one-at-a-time into the bottom dropper might help to solve the issue as well.
Draykke Devry
thanks, i wondered if that could be the problem. ill give the extra hoppers a try. cheers :D
I had the same issue with the elevator "breaking" and items accumulating in the droppers. I also had a problem with the item sorters attached to the elevators when they quit and items backed up into the sorters. Both issues were caused by too many items being presented to the elevator as the elevator trigger timing is slower than a hopper. In my case it was the simultaneous harvest of 2400 blocks of various food at once. The solution was to place a chest ahead of the hopper that inputs to the elevator. This acts as a buffer and stores the items that the dropper is not ready to accept. In fact, if you look at the way it is shown in the video it has a chest in that spot. Just build it that way and add your hopper input to that chest. Watch the chest while your system operates and you will see the items build up in there while the elevator keeps chugging along.
Ain't redstone fun!!!
I'm having an issue with items becoming stuck in the first dropper. The bottom section gets stuck on and stops pulsing to move items upward. This is on a SMP server. Seems to happen when I am a good distance away and return.
I've been trying design a way for the system to occasional (perhaps manually or by a sunlight detector) flush itself. any tips on doing this or preventing the bug in the first place? Thanks!
Sounds to me like the bug is caused when a reloading of chunks occurs; That's why it's working when you're around the elevator, and it breaks when you leave and come back.
it's actually a common bug I've heard about with ALL dropper elevators. Unfortunately I don't know of any solid fix for this outside of manually fixing the "clog" in the droppers. One thing you could try would be to hook the system up w/ a Daylight Sensor rapid redstone clock, so when a certain time of day is reached, rapid redstone pulses will be released and power the elevator (essentially un-clogging it).
I have not done any redstone work on a system like this however, but I'm sure you could easily throw a system together, or find a tutorial that could show you how to do so.
Is there a quick fix temporary or to get it working after this happens? Ie empty hopper etc delete and replace a certain item?
Replacing all of the droppers seems to fix it in most cases - something about just replacing them in their previous locations seems to reset their functionality.
he actually starts explaining how to make it at the 5:40 mark. You're welcome :U
Works fine for me on 1.8.3. Took a little while to figure out that you NEED the hopper to move the items though. I was just putting stuff in the bottom dropper directly for testing, and that wont work.
Thanks!
Edit: Works fine on 1.9! I made a mistake at first but it works! Thanks
how is it silent? I'm using droppers and they click every time they shoot out a block
