User:Fenhl/SmartChest

This is version 4.0 of the SmartChest, a storage system designed for the Cloud on Wurstmineberg. It was designed by L3viathan2142, Fenhl, and naturalismus, and is based on version 3, designed by L3viathan (/u/throwaway_redstone).

The SmartChest provides virtual access to up to 447 stacks of storage space through one double chest. This is achieved using a mechanism which moves items from the access chest into the extra storage when the access chest gets too full, and moves items from the extra storage back into the access chest when the access chest gets too empty. For the purposes of the Cloud, this SmartChest design includes an item sorter that filters out one type of item from a hopper line, and an overflow protection system which redirects items received from the sorter into a garbage hopper line when the SmartChest is full. Note that the SmartChest is intended for a single type of item, and may break when more than 5 different types of item are stored in a single SmartChest. The main part does work with unstackable items, but the sorter part does not.

Materials
To build a single SmartChest, including the sorter and half the corridor, you need:


 * 12 chests
 * 44 solid blocks (represented by gold blocks below, only 42 are needed if this SmartChest is being built against another SmartChest in the right position)
 * 6 slabs of any kind (represented by stone slabs below)
 * 27 redstone dust (26 if building against another SmartChest)
 * 15 redstone torches
 * 5 repeaters
 * 9 comparators (8 if building against another SmartChest)
 * 28 hoppers
 * 7 droppers
 * 3 furnaces (2 if building against another SmartChest)
 * 4 quartz slabs
 * 4 stone bricks
 * 10 blocks of stone
 * 2 oak wood planks
 * 2 oak wood stairs
 * 4 crafting tables
 * 2 blocks of glowstone
 * 1 lava bucket
 * 27 Ender pearls
 * 1 sign
 * 1 item frame
 * and 2 of the item that the SmartChest is supposed to store.

The design
The design is shown here in layers that will be vertically stacked on top of each other. The access chest will be on layer 1.

Layer -7
The oak wood logs here should actually be oak wood planks, since these will fit in with the crafting tables later.

Layer -2
The hopper that faces into the comparator is a sorting hopper. You should put one of the item that this SmartChest is for in the first slot. In the other four slots, you need to put items that stack to 16 (e.g. Ender pearls, signs, buckets), one per slot. Make sure that the filler item is first to be sorted in the input chain.

Layer 0
The furnace can be anything that causes the comparator to output a signal of exactly 4. For example, a furnace with 11 Ender pearls in the top slot will work.

The top slabs next to the stone bricks may be any slabs (they will form part of the corridor), e.g. on Wurstmineberg they are quartz slabs. The stone bricks may be any building block as long as it is a full block (to make sure that no items cann fall through into the hoppers).

Layer 1
The furnace next to the wall may be anything that causes the comparator to output a signal of exactly 3, while the other furnace should be something that causes its comparator to output a signal of exactly 7. For example, a furnace with 7 Ender pearls in the top slot will work for the comparator immediately behind the chest, and for the other one you can put a lava bucket in the furnace's fuel slot and 5 Ender pearls in the ingredient slot.

Layer 2
Here, the oak wood logs represent upside-down oak wood stairs which are oriented so that they appear flush with the corridor wall. You can put an item frame (represented by a ladder) and a sign on them.

Tiling
As the SmartChest has been designed for the Cloud, it is tileable to 4 blocks horizontally and 10 blocks vertically, while leaving space for hallways.
