How do you get Observer in Minecraft?

When was Observer added to Minecraft?

Observer was added in version 1.11.

How long does Observer take to break?

Observer answers to 3 hardness, and it answers to 3 when something explodes. Equal values mean Observer was never built as a blast wall, whatever else it is good for. A pickaxe shortens the job on Observer, and no minimum material applies. Java 26.2 lists Observer exactly this way, which is how it is printed here.

How many Observer can you stack?

64 Observer fill one slot, and filling it costs 384 Cobblestone, 128 Redstone Dust, and 64 Nether Quartz: 64 crafts. A shulker box of Observer comes to 1,728, over 27 slots.

Observer at a glance

Observer, a redstone component out of crafting, sits under Redstone. Carrying Observer is cheap: 64 to a slot, 576 across the hotbar, 1728 in a chest.

As a redstone component, Observer is wired into contraptions and circuits, and what it does with a signal is what gives builders the logic and timing behind automatic farms, doors and machines. It 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. It sits between Oak Pressure Plate and Piston in Redstone, number 14 of 29 there.

Building with it

Six cobblestone, two redstone and one quartz make an observer, and it fires a short pulse whenever the block in front of it changes. Crop growth, melon stems, water flow and sculk all get automated with one, because it needs no wiring at all to notice.

In practice

An observer fires a two tick pulse from its back face whenever the block in front changes state, and it watches for any change at all, not just growth. Pointing two at each other makes the smallest clock in the game, which is either very useful or the reason a chunk lags.
