HOPPER
Collects items from above and transfers them to the container it points at. Can be locked (disabled) with a redstone signal. Transfers 1 item every 8 game ticks (0.4 seconds).

Overview: what the Hopper is and does
Collects items from above and transfers them to the container it points at. Can be locked (disabled) with a redstone signal. Transfers 1 item every 8 game ticks (0.4 seconds).
As a mechanical component it converts a redstone signal into physical action rather than passing the signal onward. It is the item-logistics backbone, collecting, routing, and metering items across farms, sorters, and storage halls.
The Hopper was added to Minecraft in 1.5 and everything described here reflects its behaviour in Java Edition 1.21.
How it works: the redstone mechanics
On the input side, redstone signal locks (disables) the hopper. It returns no redstone signal of its own — its effect is a physical action in the world.
It sucks items from any inventory directly above it and from item entities resting on top, then pushes them one at a time into whatever container it points at, moving one item every 8 game ticks (2.5 items per second). A redstone signal does not start it — it locks it, freezing transfer until the power is removed.
Timing-wise, factor in transfers every 8 game ticks (2.5 items/sec) when you wire it into a sequenced circuit.
It operates in the following modes: active (transferring) and locked (powered, not transferring).
How to set it up
- 1Craft the Hopper: 5 Iron Ingots + 1 Chest → 1 Hopper.
- 2Decide where the signal needs to start or land, then place the Hopper against a solid surface so it can act on the blocks in front of it.
- 3Feed it a redstone pulse or signal from a lever, button, or circuit; it will perform its action and ignore further power until the input changes.
- 4Test in a creative-mode plot first: trigger the input and confirm the Hopper behaves exactly as the timing above predicts before committing it to a survival build.

Tips & common mistakes
- !Powered hopper is LOCKED, not active
- !Slower than water streams for bulk transport
- !Points in the direction placed, not facing player
- !Power a hopper and it stops, the opposite of most blocks; redstoners exploit this to gate item flow in clocks and sorters.
Hopper FAQ
What is the Hopper used for in Minecraft redstone?
The Hopper is most often used for item collection, item sorting systems, auto-smelter chains, and storage systems. As a mechanical component it converts a redstone signal into physical action rather than passing the signal onward.
What signal strength does the Hopper output?
The Hopper does not output a redstone signal of its own; its result is none. Its purpose is physical action, not signal generation.
How do you craft the Hopper?
5 Iron Ingots + 1 Chest → 1 Hopper. It was introduced in 1.5.
Does the Hopper add any delay to a circuit?
Yes — transfers every 8 game ticks (2.5 items/sec). Account for that timing when chaining it with other components, especially in clocks and fast doors.
Does powering a hopper turn it on or off?
Powering a hopper locks it, which stops all item transfer. Hoppers move items only when unpowered. This inverted behaviour is what makes hoppers useful as item gates in sorters and hopper clocks.
