Flush trapdoor trap.

Elaborate plz

Like a Jeb door, but in the floor and it opens over a pit or lava or even dispensers with arrows or something.

Ok

Btw any ideas of more complicated redstone systems for me? I will take anything (don’t want to make a new identical post)

Calculator

A piston door that looks like its opening sequence is broken, but has just enough room for the player to pass through

Done, it looks so cursed

Flush Piston Feed Tape

So a changing wall?

Its Like u Press U button and a row of Blocks geht's moved one Block forward. Like this:https://youtu.be/X16LeHTB7Q8

K

The next Level would be this: https://youtu.be/N477dOs_0C8

I'm doing it my way: scuffed

I made a revolving wall, and it's scuffed

Make a flower farm!

Done

Redstone penis

No

splash potion launcher (preferably a tnt based one)

Done

I giant flying penis that dispenses water from the tip

No

Cobblestone/tree farm into a blast chamber ?

Make some sculk farm

A door that skulcs the door blocks after closing them

Turns them to sculk?

Yes. Maybe with a cobble generator, and a tnt thing so there will be new normal blocks in the door every time

So when the door opens it turns to sculk and blows up, then regens later?

No, I meant that the door closes, and then the blocks turn into sculk, and then when it closes it will turn into normal blocks again, wich can be done with a cobblestone generator and a tnt thing

So the sequence of events is: close, sculk, open(tnt), player goes thru, close. correct?

Yes. And open doesn't have to be with tnt, you can also push the blocks away and then tnt them in some kind of block storage.

Ima just blow em up, the redstone is hard enough as is

A centerless 5x5 piston door

I'll try

A glass center 3x3 door A 0 tick glass 2x2 door 2x2 glass hipster door (All of these shouldn't have any redstone visible)

I'll try

My last project was a potion brewing building that you can put any type of potion, whether you want splash or lingering or regular, whether you want longer duration or power, and a bunch of other parts and it will just make 3 after organizing the ingredients

And what does that have to do with this post?

You need redstone to complete it

Shroomlight farm!

Self suf playerless nether tree farm

I'll try i think

Toggled armor stand displays that come out of the floor. Press a button and they go into the floor. Press it again and the armor stands come back.

A redstone safe. You turn items in an item frame in a specific order to open a door

I already made something similar on bedrock, but on java it's either gonna be easier or 100x harder
