How to Make EVERY T-FLIP FLOP in Minecraft!

The T. Flip-flop has an incredibly silly name. There’s no doubt about it. But it’s probably one of the most useful redstone circuits in Minecraft, and pretty much every single one of my redstone contraptions has one of some form somewhere. What it does is it converts a redstone pulse Into a constant redstone output that you can toggle on or off. So today, we’re going to be taking a look at every single variation of the T flip-flop, every design that you can possibly use. I’ve spent the past couple days thinking about this, so hopefully I haven’t missed out any obvious ones, but this should give you a very good selection to work from. Design number one is arguably the most common, making use of a sticky piston monostable circuit. Now, what this thing does is it converts this redstone pulse from the button into a one tick pulse that we then send through this repeater and into this piston, and what that one tick pulse does is it causes the piston to spit out its block. Now sadly this only works in the Minecraft Java edition because that is the only version of Minecraft that actually involves this piston spitting mechanic, which is a bit of a shame because it’s incredibly useful. I use it pretty much everywhere. Now this right here is a semi-silent version of the T flip-flop. When we hit this button, you can hear we get a tick but we don’t get any piston noises going on, and it works by cycling items around inside the droppers. So right now the item is inside this dropper right here, and when we hit the button it gets sent up into this dropper because this dropper is facing upwards, and then when we hit the button again the item gets sent across, it goes into this dropper here, makes its way down into this hopper, which then cycles it back round into that dropper there, and you take the output out the side with a comparator, which then of course runs out to show off this redstone lamp. An alternative way of using this configuration it is to run a dropper facing upwards, a dropper facing across, a hopper facing down, and then a dropper running back across into this dropper here. So it kind of goes up and round in a cycle and that means that you can take the comparator output from directly behind the button. So it’s kind of all in line like this as opposed to coming out the side. It’s a pretty good alternative. This design right here works in a similar fashion to the first one, making sure that we have one tick pulses to cause this sticky piston here to spit out its blocks. But instead of using a monostable circuit, this actually makes use of observers being moved, which means that we’ve managed to shave off one block of the total length, and also, we’ve managed to make it a little bit shorter as well. It’s only two blocks tall. A design that I distinctly remember working back in the olden days was this system right here where you had some water and also a boat, and you hit the button and the water would be removed and then the boat would land on the pressure plates, and then you press the button again, the water will come out and the boat would flow upwards, turning off the pressure plates, but sadly that doesn’t seem to work anymore, which is a real shame because this thing looks hilarious. Now this right here is one of the oldest T flip-flops I can possibly think of. This is what we we’re using in the early days of pistons. What you do is you just press this button right here, and you can see that the block moves across So it toggles every single time you press the button. Now the only slight issue with this design Is that it’s known as a falling edge T flip-flop. and the reason for this is is that it only activates on the falling edge of the pulse Now the falling edge is when the pulse actually ends. so when we hit this button you can see it’s powered and then when it unpowers, that’s when it switches over. But despite this. It’s an incredibly compact design.
That’s also fairly cheap as well. next we’ve got another observer based design, which relies on one tick pulses. But this one is only one block tall and is only one block wide as well so its 1X1X6. Now that is not particularly big. I mean, a six blocks in total T flip-flop they don’t get much smaller than that, and you can see that you’ll be able to slot this pretty much anywhere. If you’ve got a Compact redstone circuit you’ll be able to wrap this around. This design may look fairly similar to this design over here But whereas this one is a falling edge T. Flip-flop this one is now a rising edge T. Flip-flop Now unfortunately it has been made a tiny bit bigger but it activates at the start of the pulse as opposed to activating at the end of the pulse Which makes it… well tends to make it a tiny bit more useful in real-world situations And as you can see we’ve just got redstone, redstone torches We’ve got both of our pistons right here And then the red stone and the redstone torches underneath pretty simple to build. If you’re looking for something a little bit on the daft side, then this is the perfect T Flip-flop for you. As you can see we hit the button and it activates the detector rails as it travels past, which therefore push the block back and forth between the pistons. Now, I’ll be honest, I don’t know how many of you are going to find a use for this one I mean, it’s it’s a bit of an obscurity flip-flop circuit But who knows? You might have a lot of minecart rails and not a lot of redstone resources, then it’s perfect. Now then this is the first T Flip-flop circuit that we’ve seen today that makes use of locking repeaters. So we’ve got a little redstone circuit right here in fact I’m going to fly on top of it, so you can take screenshots so that you can build it for yourselves But when we hit the button the repeaters will unlock and then They will re-lock and we have got redstone turning off right here So we take the output from That redstone dust there. Now the only thing that I’m going to warn you about is that this will not work if you’re using anything other than a stone button. it relies on the 10 ticks. You can see with a wooden button, which is 15 ticks, That’s not going to work. So definitely something to watch out for with this circuit Is it’s entirely timing based. This one is a bit of a quirky one But it’s also incredibly tiny. As you can see it involves two sticky pistons And then we have a redstone torch and a block and this block right here is our input, and every single time we press the button it kind of changes shape It changes the way that it does it. So on this one this piston retracts and then this piston retracts pulling this down, and then this piston pushes across, whereas on the other button press this piston pushes up And that this piston pushes across, giving us a comparator output. Through into this redstone lamp. now if you’re wondering why I’m not using a redstone block, that is because this piston right here wouldn’t be able to retract in that case. so you have to make use of a filled cauldron. However, with this sideways version of the design we don’t have that problem We’re not getting any BUD powering going on which means that we can make use of the redstone block. Now It’s still a falling edge monostable circuit, And we have made it a tiny bit bigger because we’ve had to add in this extra dimension up here whereas this one’s one wide, this one is now two blocks tall but that does mean that you’ve shaved off the comparator and Also, you’ve reduced the amount of iron that design uses by quite a long way, as cauldron are pretty expensive. This little system is pretty interesting. It’s another droppper-hopper T flip-flop but instead of using Cycling items are the ones over there, this one makes use of redstone circuits to lock the item in place. So the item is currently locked inside this hopper which is faceing into this dropper with the dropper facing back into the hopper, and when we hit this button it will very quickly unlock the hopper allowing the item to travel through into the dropper Then when we hit the button again the item Gets shot from the dropper into the hopper and the hopper locks just in time to keep it in place so we get the takling mechanism If you want to do a really quick and dirty T flip-flop system that also has a bit of a flash in between, then you can do this one. You hit the button and It will flash once and then stay like this, and we hit the button again It will flash once and then turn off. Now the way that this works is we’re essentially Locking the hoppers in their position so we hit this button Unpoweres, item goes back and forth and then gets locked in one position And then we hit the button again items goes back and forth and then it locks in the other position. Not necessarily adviced for most redstone circuits, and also it requires a 10-tick pulse from this down button. Nothing else will work. Another system which makes use of observers and also one tick pulses, is this one right here. Now for those you don’t know observers can detect redstone updates from hoppers They give off a redstone update when they become powered, which means that all you have to do is quickly power this hopper right here, and that will allow the observer to detect it and spit out the redstone block. Now this is a falling edge monostable circuit But it’s pretty compact and also relatively fast at detecting the falling edge. Now this little thing has to be one of the smallest T flip-flops I’ve ever seen it’s four blocks in size and it’s completely self-contained with the comparator inbuilt. So when we hit this button the item would be spat out from this dropper right here and go into this hopper Which will then put the item inside this dropper, and then when we hit the button again, the item will be sent from this dropper upwards into this dropper which will activate our comparator. hit the button, it cycles around, you guys get the picture the only thing that I would be a little bit concerned about is if someone stands too close, They might potentially pick up the item. it would be difficult, but it could potentially happen. These two designs are actually fairly similar, they work in exactly the same fashion, and they’re essentially better versions of this redstone circuit over here So instead of having the item travel back and forth a lot what this will do is It will do it with a 1 tick pulse Which means the item only has enough time to travel between the hoppers once. Now the only issue is with these designs They are falling edge designs, which means that we’ve got a falling edge T Flip-flop once again, but they’re tiny, and they’re relatively resource light. As I said, this works in exactly the same way It’s just a much bigger way of doing it. This one is a bit of a wild card coming from the early days of redstone blocks But it still seems to function. The way that it happens is we’ve got a monostable circuit happening right here with the input into this block which causes this piston to retract and extend quite quickly and that retraction and Extension is then transferred into this piston using this redstone block causing it to spit out its redstone block Which will give us a toggled output of course with this using one tick pulses? It’s only going to work in the Java edition of Minecraft. And the final design for today is this. If you want a constant output, then you could always use a lever I mean, that’s generally the comment I get when talking about T flip-flops, but anyway ladies and gentlemen I hope that you enjoyed this video I hope that you found it informative.

  • Or use a lever 😂

  • Useful on crossblock redstone

  • Wii u edition also has piston spitting mechanics

  • I learned how to make a t-flip flop from grian


  • all you redstone wizards should be in electrical engineering

  • Ya srsly, u would we use t flip flops if we have levers XD

  • I use my custom design. It works with a hopper clock, which is disabled by two redstone dust on the top, activated by a redstone torch, and there is two repeater set to 2 tick, going into the hoppers. When It gets any signal, the redstone torch will be disabled, so the clock can start, and after 1 tick (because the torch delay is 1 tick) it will be disabled.
    Simple, silent, fast. (it is a falling edge flip flop)

    The "fixed" rising edge version of that falling edge flipflop at 3:52 can be better.
    You start from the original one, put one more block next to the top redstone line, and put a redstone torch on that. And the activator signal goes to the added block. Now it is a rising edge flip flop

    I don't like the dropper or piston flip flops because they are loud. For a trap you need a silent system.

  • What is wrong with leavers

  • In 1.14 t Flip flops arent working

  • Mumbo

  • Ik ur name

  • But wonttell

  • First letter o

  • But ur grian i think

  • For the broken one you Can just put soul sand under the water

  • I heard Pewdiepie shout Creeper, Aw Man from my sisters room and I sang the first part of the song

  • 5:00
    Mumbo : it will not work if you use other than stone button…

    MCPE Player : it will not work if you use stone button…

    (I have tried it my self and you cannot use stone button but you have to use any wooden button to make it work on Pocket Edition)

  • what is t flip dlop

  • Mumbo the first one work fine on ps4 and xbox 360
    Edit: all the 1 pulse design worked fine on both ps4 and xbox 360 so i suppose the legacy version of minecraft

  • I found this other pure redstone T-Flip-Flop at made by WhamyKaBlamy but with v. 1.14.4 the input repeater needs to be set at 4 delay or you get a double pulse on one of the channels. BTW, thanks for the description of how each of these works. I'm just getting into this.

  • Which works in PE?

  • For some very smart people in the comments, levers can't convert a pulse to a constant redstone output, levers have to be turned on and off manually so you can't use levers inside redstone circuits

  • i know this has probably already been found out but if you use redstone dust as the thing the t flip plop activates with the first example its like a temporary clock

  • The first one works 90 percent of the ti,e on minecraft ps4 edition

  • Let share the video to grian

  • Finally I know what is flip flop

  • just use a lever LOL

  • Very useful!! I only knew a few of them, so I had some difficulty to compact my redstone builds. I really like those using observers. Thank you Mumbo! Maybe not the funniest video to do for you, but I really like it!

    PS: I want to thank you very much. I'm getting better at redstone as the time pass, I'm getting more and more fun to build my own redstone contraptions, and that is 99% thanks to you. You're the best. Keep doing what you love, keep having fun, and keep taking care of this beautiful mustache.

  • Me: builds a bunch of redstone circuits in my house using t flip-flop to toggle hidden stairs, showers, etc,
    Also me: Looks in creative inventory 3 days later and finds a lever

  • Everyone else: uses at least one of these flip flop switches
    Me: uses a lever

  • The first version of t flip flop you showed works on ps4

  • Why not repeater T-flip flop

  • it also works on ps4 edition

  • A lever

  • I can now make one press button piston doors! Thanks!

  • its t-flop mumbo

  • Ah the lever. The original t flipflop….

    A.k.a. the tlever

  • Outro :p

  • cries in bedrock

  • T flop

  • the advantage a t flip flop has over a lever is it can accept input from multiple buttons, so u can have buttons in various places for convenience that all toggle a single output

  • 2:32 this is nothing if you took a 3 long pane of glass and put a boat on it if you shot another 3 long pane of glass on its left side the boat would fall shoot it on the right side the boat would rise so legit wireless Redstone I used this on Xbox to set off spawners around the world so it was an apocalypse

  • send this video to "what the hell is a t flop" grian

  • why you dont use a lever?


  • Ya like jazz?

  • Ni**s out there making sticky pistons not pull

  • Well this was hella ez to make i thought it was hard (made the first design)

  • thanks, now i can make a man wearing flip flops!

  • oh i was thinking about a monostable circut

  • you mean t-flops

  • Buttons look better than levers.
    Comment if you agree.

  • So the boat t flip flop doesnt werk ye say? Not on Bedrok! LOL

  • The boat one could use a soul sand to push the boat back up.

  • 2:42 Thats the only tflip-flop I use

  • T-flop

  • Got any for console? Because half of these don't work 100%of the time

  • #1 works on ps4 edition to!

  • He says that this is the only version of mine craft where sticky pistons spit out their block when they have a 1 tick pulse but it works on legacy console too

  • The boat one works on Xbox

  • So most of these don't work anymore?

  • I remember making one before pistons were a thing, took like 12 squares if not more!

  • For the boat one you can use soul sand to make the boat float

  • The first T flip flop works on legacy edition (PS4 mine craft)

  • 3:26 that's what she said

  • In bedrock, the old ass piston falling edge one doesn't work. They work fin if you want a random output though. This, for some reason, is fixed by placing above the two cerntral blocks an observer with the output down, and a piston to push it. Activate the piston and the obvserver moves, sending a pulse into the flip flop and bam, it switches.
    I dont know why this works, I think it has something to do with how short the pulse from an observer is.

  • I’m trying to add swing to a fast note block piece. Does anyone know how to silently add a half tic delay?

  • The first one worked on PS4, Just want to tell you.

  • These are useful for making multiple switches to a light.

  • hey mumbo, i tried building the 3.30 design vertically but it doesnt seem to work? any idea why? the redstone block just gets picked up again by the 2nd sticky piston

  • Dropper Hopper T Flip Flop. Try saying that ten times fast

  • In the ps4 edition the pistons spit the blocks out too idk why no one mention s it

  • Use soul sand then the bote one will work

  • Levers: im gonna end this mans hole careet

  • "Oh yeah boats sink don't they?"


  • I'm not trying to bash on anything, but I'm honestly quite confused, as you said "could just use a lever"
    so when would you really want to use a 1 tick pulse / t Flip flop instead of just using a lever?
    i know 0 tick (glitch) farms exist, but would you mind doing a video on kind of how a flip flop is used in logic circuits or other builds?

  • “Dropper hopper t flip flop” he’s speaking the language of the gods

  • Why are they called t flip flop?

  • T flop

  • Grian wants to know your location

  • Mep

  • hi im time traveler from 2019
    in just wanna to say that pewdiepie will hit 100m sub
    and he will name his fox FLIPFLOP

  • Looks like people forgot about xbox 360…

  • T-Series Flip Flop

  • Knowing about a flip flop circuit and how they work helped me under stand how a kill switch on an electric guitar. So thank you a lot

    But know it's off to digging out how to make them IRL

  • Blip Blop

  • "Flip flop"

  • Hasn't anyone noticed the Dutch subtitles?

  • The problem with the second design is It would be difficult to make a fast binary counter with that design.

  • Can't you just use 2 droppers facing each other and take the comparator-output from one of them? that would make a 1x2x1 T-Flip Flop circuit

  • Come on everyone, redstone is so easy to understand compared to commands

  • RIP PE users.

  • I just make my own Button act like lever redstone construction LOL its so big but it works

  • 4:25 – Could be used to indicate cart departure & return.

  • All the one with pistons don’t work on bedrock ;-;

  • you know what? T.flop is hard…. isn't the lever better? thats just 1 block t flop

  • Why is this still not it's own block yet. Simple name, "Powerable lever".

  • 2:16 that's what she said

  • sounds like a rapper name "Yo yo yo, T- FlipFlop in da house!"

  • You forgot a lot of t flip flops
