Nullifier

Sends all the things to /dev/null!

A nullifier is a device that destroys any items and fluids it receives.

Obtaining

A placed nullifier 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.

Usage

Placement

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

Operation

When a nullifier receives items or fluids, they are instantly destroyed. Items and fluids can be supplied to a nullifier manually or automatically.

Input

Items and fluids can enter a nullifier through the front, which displays lava when the device is active. Other sides of a nullifier can also be configured to accept items and fluids using the Configuration tab in the device’s GUI.

Redstone control

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

Ignored

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

Low

The nullifier is active when not powered. When powered, it becomes inactive.

High

The nullifier is only active when powered.

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

Security

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

Redprints

A nullifier’s configuration can be saved on a redprint to be copied to other nullifiers.

Light source

When a nullifier is active, it emits a light level of 15.

Trivia

• A nullifier works by “sending things to /dev/null”. On Unix-like operating systems, /dev/null is a null device, which discards any data that is written to it.
