Overview
Observer is a redstone component in the Redstone category of Minecraft, obtained through crafting it. A single inventory slot holds a full stack of 64 Observer.
As a redstone component, Observer is wired into contraptions and circuits; its behaviour is what gives builders the logic and timing to automate farms, doors, and machines. Observer is a 3-hardness block. Mining Observer and blowing it up both run into 3. A pickaxe shortens the job on Observer, and no minimum material applies.
