This is not a redstone contraption.

This Minecraft build is not a Minecraft redstone contraption, it's a sound-stone contraption! The calibrated sculk sensor was introduced in Minecraft snapshot 23w12a, and will be added in the Minecraft 1.20 Trails and Tales update. The new Minecraft update introduces a tonne of new Minecraft redstone features - the new sculk sensor allows us to create wireless redstone in Minecraft, and send messages in Minecraft using Minecraft redstone.
