Works great in Java 1.21 (single player). Thank you 👍
I built this in my SkyBlock world.
I also slowed down the clock by another 4 ticks which increased the output of the farm.

Nice and compact design, earned a sub!

[@docspel]

Thank you! I'm glad you liked the design.

[@Moon-no3ts]

Man a new revolution

[@Lordff5383]

Thank u so much ❤❤❤😊

[@docspel]

You're welcome!

This design has 2 problems, here are the fixes:
1- remove the water and the trapdoor from the middle of the roof, let the trapdoor and water over this block only.
2- extend the time of the redstone-clook, i used 2 more repeaters at 4 ticks

[@thedrdroppedme]

Can you elaborate on these fixes, I'm having trouble getting this one to work. Clock gets stuck, and the TNT doesn't drop

[@thedrdroppedme]

Nevermind. I got it!

[@KatLovesOcelots]

still building. seems ok. simple enough for a not so newbie, but the speed of placement (and them doing it in creative) means checking a couple of times if it's correct, and a suggestion if you're building it in survival, like me, extra ladders are helpful to get up (at least 4, or more if you want some on another side), and at least double the trapdoor count!! lucky I had some wood nearby, and just take note of the direction of the placement of the trapdoors or you have to fix them and play with lava like I did. fun fun. lol

[@KatLovesOcelots]

and you also need a lever. it's working now. works great. thanks very much for the design. it will come in handy for our builds. good luck everyone.

[@KatLovesOcelots]

thanks to @rcorral1989 for the fixes.

[@GSeraf1m]

Wonderful design

[@Cotton_Door42]

im pretty sure this is a great farm, but the one problem i have is that my glass breaks and water flows to where the chests are, i dont really know if this is ruining the farm, do you have any fixes? im still getting cobble stone. Dont know for sure if its a problem though :)
EDIT: Figured out the main problem is the redstone clock, the clock in this build is too fast and fires tnt when another is active, moving a tnt and blowing up things that shouldnt be.
added a longer clock and the farm works perfectly!

[@nicholaslambers4918]

I’m in Java and just built this and the server isn’t laggy. I press the button once and it activates once but doesn’t continue.

[@RealStrikzZ]

Sounds stupid but make sure its a stone button and not a wooden one. Stone one is a shorter pulse. A woodens button pulse is too long for this clock to get started

[@rizkiors424]

I don't know why the TNT doesn't glitch repeatedly, I've made it repeatedly but the results are still the same, please reply, I'll send you my server so you can see it directly

[@docspel]

This farm only works on Java Edition. If your server is on Java and it still doesn't work, it might be due to server lag.

[@evilseven9531]

Everything works on the farm, but the tnt won't fall down in to the chamber how should I go about fixing that?

[@AndMagedon]

good content!

[@jadedstonedmonkey]

Miscounted the trapdoors you did, stated not the version java or bedrock?

[@docspel]

Sorry about the miscount of the trapdoors! This tutorial is for the Java version only.

[@sup3rlucas865]

nice

[@zeiraikamizu1098]

This farm is more expensive than sulkerfarm(i dont remember his name). This farm needs 24 lava buck but sulkerfarm just 18

[@RedRider_Fruits]

My tnt only falls once and once it falls the obsrrver on the pistion gets pushed where the tnt was and it wont work

[@RedRider_Fruits]

This is java

[@YashSingh-wu6uu]

It can work on any online server too ?

[@qoisnahwal]

❤

[@rcorral1989]

java here, and didnt work. can you upload the world pls

[@docspel]

You can find the download link in the description

[@lenguyengiahung8122]

is this java version ?

[@docspel]

Yes, it only works on Java.

[@GheeMann]

Does not work on multiplayer servers

[@MeenaKumari-we1qx]

Bro only Java?

[@docspel]

It's only for java unfortunately

[@coldxushi]

Common sense says we can't dupe tnt on bedrock

[@Dyas19546]

doesn't work on paper or purpur server

[@haskeyboy1236]

didnt work

[@docspel]

Make sure you're using the Java edition of the game and following every step closely.

[@TobyPhillips-io9pp]

This is by far the worst tutorial i have ever watched lol, nearly impossible to know what to do

[@docspel]

Sorry to hear that! I'll work on making future tutorials clearer.
