A small device that takes in boxes and outputs items for filtered storage systems, ensuring no more than 1xDefinition: Refers to the speed at which items are processed in a hopper (1 item every 8gt, or 2.5 items per second). Usually written as an integer (e.g. '3x hopper speed'). ## Common hopperspeeds 1x: 9000 ite... hopperspeed per item type and capable of outputting up to 5 different item types simultaneously for up to 5x hopperspeed.

Features

• Very small, only 11x11x12
• 4D alignDefinition: Perfect item aligner refers to a contraption that aligns items in all three axes before sending them down a stream, where they usually get picked up by hoppers. Since these contraptions are usually...ed item output
• Separate unstackable and empty box output

Considerations

• Slow and cannot be expanded beyond 5x hopperspeed
• Does not work with SSDefinition: Abbreviation for redstone dust/comparator Signal Strength3 filters, items are output with a max stack size of 62/14

Notes

Built on ST2 CMP (par unloaderDefinition: A contraption that removes item contents from a shulkerbox. dev waypoint). Uses a modified version of the OIP002Hopperspeed Item Entity isStackable item entityDefinition: Item entities are items in entity form. Each item entity can have a full stack of items, up to 64 items for 64-stackables. ## Item entity tick Every game tick, item entities will do the following ... unstack separator (OIP002 Hopperspeed Item Entity isStackable)

Explanation

This device uses hoppercarts to ensure only a full stack of a single item type is output at a time. A single hoppercart is driven beneath 5 boxes, allowing it to pick up the first item type of those boxes. Then any remaining empty slots are filled with dummy items. The cart is driven under the boxes over and over again, for 512 gtDefinition: Minecraft iteratively runs its processing code in a loop. One cycle of this loop is called a Tick or Gametick (gt). Gameticks are also used as the default measurement of time while working with re... to allow all slots to be filled completely if possible. The cart is then yeeted and the output is brought to an unstackable filterDefinition: A system to filter out unstackable items from a stream of stackable items. Usually done by reading the signal strength the item produces when in a container. which removes unstackable items and separates 2 items from the stack to be sent separately 16gt later (so item stacks have max size of 62/14 and can be filtered).
