Insane Redstone Trick! EthosLab’s Hopper Timer Tutorial

Hello everyone this is etho and i have another tutorial for you guys today this one is very special I’m showing you my new property more inventions here hopper clocks these things are absolutely amazing so previously in Minecraft before this redstone update the way we’ve been keeping track of timing and

Redstone circuits we usually use different methods like if we want five minutes we will use items desponding to trigger a signal or if we were looking for like a one minute timer we’ll use an arrow despawning or we can use cobwebs to items falling through cobwebs to get

24 seconds each cobweb they travel through that kind of thing now with this hopper timer device we have a very precise way of timing stuff over a long range with a lot of flexibility so I’ll show you this this is really cool basically I have to hoppers feeding into

Each other here and the items that we put in here ping pong back and forth between the two with this setup so if we put eight items in and see if Foley empties into this one and then these items start going to go back into here

Until it’s full and then back again so it’s being pounding back and forth and with this we can generate a redstone pulse at a fixed length of time each item we put in AD 70 to the delay or 0.7 seconds but there’s also a half a half

Cycle method we can use to get even more precision with this but at the expense of having the maximum time this will run for so with these hoppers we can put up to three hundred and twenty items in and that allows us to make a timer somewhere

Between the range of like zero to three minutes and 44 seconds roughly depending on how many items we put in here accurate – seven six all right guys I’ll run you through how to build these even though you can probably see it here because they’re only one tall there’s

Two different versions I have the piston version here which is more compact but a lot more noisy and then we have the silent version here the silent redstone version so let’s build this one first basically to make a hopper face another hopper you have to hold shift and click

Facing that hopper you want it to connect to like that and if we do the same for this one they connect like that then we put two comparators one on each side two blocks redstone and then pistons with a redstone block between two like that let’s try it out that’s at

Maximum speed if we had more items it slows down whoo thank you all right so let’s move on to the redstone version hopefully I can remember it again same deal two hoppers facing each other and then two comparators on the side and then we have blocks on both sides redstone torch

This goes into a repeater and then we have over here this is really important on both of them we’re using an RS nor latch that’s kind of the trick to this all so that this is a way of building a redstone arson or latch do that and that

And then we connect this to there like that and we have ourselves a redstone version let’s try it out you see it’s starting to pulse we had more it slows down very cool very very cool let’s get a no block in here so we can make sure it’s working

Oh yeah that’s nice so maybe let’s look over some of the tricks and cool features of these hopper timer things first of all one thing I really like about them is they’re very easy to control like if we want to stop it we can put power pretty much anywhere to

Stop it if we do that all tight um’s gather to this hopper if we put it on this one all items gather to the opposite hopper we can power the hoppers themselves and that freezes it where it’s at because both hoppers are being powered at the moment this one from

There this one from here believe if we wait it if we wait then they’ll all go to this one if we we can power OOP you can borrow the redstone to stop it or the Pistons themselves what’s really cool with this is we can actually use it

Sort of as a stopwatch if we want it to stop timing for a moment but we don’t want it to lose lose its count like where it is in the timing process we can just do something like this and have both hoppers being powered at the same

Time and then if we unpowered them it’s free to run again but then if we do that it freezes so we have 20 in there 3 in there and Stearn account up again it we can freeze it again and it remembers where it is in the timing process that

Way so we have the option of stopping it to it like where one of them is all full and start this the start of a cycle or we can stop it in the middle of a cycle something neat you can do with this piston version of the timer if you were

To run wire across both these blocks here you can actually pick up the half cycle timing so that makes it twice as precise instead of every item counting for seven ticks in the timer every item will count for 3.5 ticks that does reduce the maximum timing you can have by half ago

So keep that in mind this is also a really nice way of getting a quick pulse out of the thing if that’s what you’re looking for nice one big pulse there there’s also some weird things you can do with these half picks I’m not going to get into too much detail but I’ll

Just show you an example of what I mean if we were to do this you can get a better idea basically using the same wire you can detect if it’s the half cycle or the full cycle like this one’s pulsing every time this one’s only pulsing every whole cycle so just this

Weird little quirks without the repeaters work with haptics like that in use but that is pretty complicated same with this thing I if you want to get the half cycle out of it you would have to do something like this I believe pull it from both sides put it into a block and

Then it’ll pulse every half cycle um if you want a quick pulse like a one pick pulse again there’s a trick you can do here if you just run wire between this block and that torch and then we can invert it although I think we might need

A repeater yeah it’s too quick when you’re Peter to catch it there now we’re getting a one pick pulse very cool so even though these hopper timers are extremely cool there is two main flaws I see with them or two things they can’t do first of all they’re not

Very well they are precise but they’re not to the tick like that you can get within seven ticks so for example if you were trying to get one minute exactly from these you might not be able to it might be like one minute and and point three seconds or something like that you

Know it’s not exact necessarily within that point seven seconds is the accuracy now the other issue is there’s no way to quick reset it like if you start the timer then you stop it and then try to restart it to real quick it can’t it has

To wait for the items to flow through the hoppers which you can think of at a time so that’s the other issue but that being said they’re still very cool and very useful I plan on using them a lot now let’s look into how to calculate

Exactly how long your timer is going to be based on how many items you put in it so I wrote out a book here with some formulas it’s complicated I’m sorry I’ve spent hours trying to understand this now and I’m still not at the level of comprehension I want to be

But I’m going to keep keep experimenting with this so here’s my book one tick translate to 0.1 seconds in Minecrafts so they’re interchangeable one item every item we add add seven ticks or 0.7 seconds to our total time unless we’re doing that half time thing then it’s

Half of that and then this is a formula item times item time which is 0.7 times base time depending on which one we’re using this one is wait did I write that right yeah this one is negative negative three I guess we do negative 0.35 seconds and this one is positive

0.7 seconds so let’s let’s just do an example here let’s say we put 30 items in the one on the right here we times that by item time is always 0.7 unless we’re doing the half time then it’s 0.35 but 0.7 and then plus base time the base

Time for the silent redstone one is 0.7 equals our total time so I’m just gonna get my calculator here thirty times point seven plus point seven is twenty one point twenty one point seven seconds exactly it would be our timing with 30 items let’s say we wanted to figure out

A specific time how many items we need for that then we can use this formula here so let’s say our our target time is thirty seconds so time in brackets here at minus base time which is this number here zero point seven like eyes that is Compton this is divided divided by item

Item time which is zero point seven unless we’re doing the half time equals let’s figure it out through to you – point seven and then divide by 0.7 to denta equals forty forty-one items point eight five seven one four so forty-one items plus 0.85 and all that we can’t actually have part

Of an item in it though so that’s where the inaccuracy comes from if we figure out exactly we can figure out exactly how much that is if we do 0.857 that number there times zero points seven equals and I know this already this is 0.6 ticks so basically we’re missing six ticks

From our C from our timer here so if we added that on the end of here when we first start up the clock it would be exactly thirty seconds if we had 41 items in the hoppers but then every every cycle after the first one it’s not

Going to be that it’s going to be it’s going to be 41 times item time zero point seven plus zero point seven equals I’ll just figure that out twenty-nine point four with 41 items in or even even with this repeaters at the end because they’re not actually lengthening the the

Loop here they’re just afterwards so if you’re aiming for 30 seconds put in 42 items and that will be thirty point one seconds so that’s as close as you can get but anyway that’s kind of the way it works I’m going to keep experimenting with this and look into it further as

You can imagine you can also combine two of these at one as a multiplier to get extremely high times or I’m going to look into using a dropper hopper combo so that basically every pulse this gives out it will send out one item to the hopper you’d have to have that powered

Just get a torch and put some items in here so they’ll stay in here every time we send a pulse like from our timer here it would send one item into the hopper and then when this hopper is empty it would send out a signal and that would reset everything

So doing something like that you would get three hundred and twenty items or three hundred twenty times our maximum which is three three minutes and you can imagine the crazy amount of times you could reach with that just figuring it out now 60 that’s not that crazy

Actually it’s about a day or so just under a day I think if I figured that out right but anyway that’s going to be it for for today guys I hope you enjoyed this and found it informative it’s a bit complicated but it’s actually a very

Cool timer you don’t have to worry too much about this if you don’t if you’re not worried about exact timings like you can probably eyeball it too and just don’t worry like just toss items in until you get a timing that looks right for what you’re doing that’s another way

Of just timing stuff too without doing all the math but alright thanks for watching bye bye
