Vacuumulator

Yes, this block sucks.

A vacuumulator (also known as an item collector) is a device that collects nearby dropped items.

Obtaining

A placed vacuumulator can be instantly picked up by dismantling it with a wrench. Its configuration is preserved in the item. It can also be mined using a pickaxe.

Crafting

Usage

Placement

When placed, a vacuumulator faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.

Operation

A vacuumulator collects dropped items in an 11x11x11 area. It attempts to collect items every 16 ticks (0.8 seconds), or directly after it is activated by a redstone signal.

Input and output

Items can exit a vacuumulator through its sides. Every side of the device may be configured to be able to output items.

A vacuumulator can automatically transfer items out of any configured output sides. This is called auto-output, and occurs every 16 ticks (0.8 seconds), right before more items are collected. The device can automatically transfer up to 64 items at a time.

Which sides can output items and whether auto-output is enabled can be configured using the Configuration tab in the device’s GUI.

Filtering

A vacuumulator can be configured to only collect items that match a given list of items. This can be done by using the placed vacuumulator while sneaking. It has various options that determine how this list is used to match items.

Blacklist/Whitelist

Treat the list of items as a blacklist (collect all items except these) or as a whitelist (only collect these items). The list is used as a blacklist by default.

Ore Dictionary

Match items that are considered equivalent, like the various versions of copper and tin ingots added by different mods. This is ignored by default.

Metadata

Match items by their exact metadata / damage value. This is ignored by default.

NBT

Match items by their exact NBT data. This is ignored by default.

Redstone control

A vacuumulator may be configured to respond to redstone signals. It can be in one of three modes:

Ignored

Redstone control is disabled. The vacuumulator is always active. This is the default mode.

Low

The vacuumulator works when not powered. When powered, it stops working.

High

The vacuumulator only works when powered.

The current mode can be set using the Redstone Control tab in the device’s GUI.

Security

A vacuumulator can have a signalum security lock installed to restrict who can access it.

Redprints

A vacuumulator’s configuration can be saved on a redprint to be copied to other vacuumulators.
