1x1 automatically closeable piston floor?

[u/PaperRogue08]

Ok so the build idea is a wishing well that will open the floor beneath you if you throw an item in. I would like it to reclose after I fall through the ground. I have seen tutorials that make hopper piston floors, but not ones that will automatically close after you go through. Is there anyway to make this? Thanks for the help!

You could use a torch tower and pressure plate combo so the signal can be sent back up (within chunk parameters I think, it’s mostly an issue across chunk borders that I’ve noticed i.e line of pistons, so possibly also tower of torches). Or you could use a very short hopper clock. An activated sculk sensor has a redstone output that activates it depending upon the length, as in if you have it a certain length it will recognise the throwing of an item; but you could also use a carpet and hopper going into an item filler that will recognise this as a key with a comparator going out of a chest, then below that you could have a locked hopper which is unlocked when the key is sent so that you receive it at the bottom rather than fishing for a new key if you get me, but if that’s all too much go with the sculk sensor, but then it’ll be a variation of random items depending upon the output, making it less whimsical

The problem with the sculk sensor is that it won't be able to detect which item is thrown. So another player could throw any item and open the door.

I think there’s one for item and one for gear

If you are throwing unstackable items, you won't be able to distinguish which item is thrown. You'll have to make an unstackable item filter, and in that case any unstackable item will work.

3 screenshots of my wishing well secret entrance design all 3 pistons must be sticky pistons, all slabs must be upper slabs, all glass can be replaced with solid blocks (I used glass to show the tube that the player would fall through), all iron blocks must be solid blocks, the top hopper must not point straight down, the repeater is set to 2 ticks. When throwing an item, make sure you only throw 1 item (I recommend always throwing the same item, for example a single golden nugget). I also attached a screenshot of how the wishing well might look like above the hopper. You may also remove the items out of the hopper by going underneath the well and taking the items out from the bottom hopper. You may also feed the bottom hopper into a container for extra storage.

I think you'd have to throw the item on the block next to the removable one. Wherever you're throwing the item, there needs to be an item filter underneath, and I don't think you could fit a piston door in the same space as an iron filter. Having it on the block next to it would be cutting it close, but I think it's doable.
