# Auto-Regulated Cobblestone Generator

Automation of a cobblestone generator is simple, just face an <ItemLink id="annihilation_plane" /> into a standard vanilla
manual cobblestone generator. However, doing this will eventually jam your network full of cobblestone, so some regulation
is desired.

Due to how annihilation planes work (they act like <ItemLink id="import_bus" />ses), we cannot simply put a <ItemLink id="level_emitter" />
facing an <ItemLink id="export_bus" /> with a <ItemLink id="redstone_card" /> (since you cannot go directly import to export
with no storage in between). We have to be a bit more roundabout.

<ItemLink id="toggle_bus" />ses allow you to connect and disconnect parts of your network with redstone signals, but they cause
the network to reboot whenever they do this. There is a simple workaround: put the toggle bus on a [subnetwork](../ae2-mechanics/subnetworks.md)
such that it only reboots the subnet.

We can have a self-contained <ItemLink id="annihilation_plane" /> and <ItemLink id="storage_bus" /> [subnetwork](../ae2-mechanics/subnetworks.md)
push into an <ItemLink id="interface" /> on the main network. The toggle bus will connect and disconnect the subnet from a
<ItemLink id="quartz_fiber" />, cutting power to the planes.

## Configurations

* The <ItemLink id="annihilation_plane" />s (1) Have no GUI to configure, but can be enchanted with Efficiency and Unbreaking to reduce power draw.
* The <ItemLink id="storage_bus" /> (2) is in its default configuration.
* The <ItemLink id="toggle_bus" /> (3) must be on the subnetwork side of the quartz fiber, not the main network, or the main
  network will reboot every time it toggles.
* The <ItemLink id="level_emitter" /> (4) is configured with the desired item and quantity, and set to "Emit when levels are below limit".
* The <ItemLink id="interface" /> (5) is in its default configuration.

## How It Works

1. The cobblestone generator makes some cobblestone.
2. The <ItemLink id="annihilation_plane" />s break the cobblestone. 
3. The <ItemLink id="storage_bus" /> stores the cobblestone in the <ItemLink id="interface" />, sending it into the main network.
4. When the amount of cobblestone in the main network exceeds the set amount, the <ItemLink id="level_emitter" /> stops
   sending a signal, turning off the <ItemLink id="toggle_bus" />.
5. This cuts power to the subnetwork, stopping the annihilation planes from working.
