User:Holroy/RedstoneSchematics

Here I want to gather some of the schematics I use in my main world. Sources for the schematics are either the wiki, youtube videos or my own construction. I play bedrock edition on Nintendo Switch, so I'm only going to link relevant schematics.

Simple auto furnace
In most of my bases there is always one of these, it allows for easy dropping of up to 5 stacks of smeltable items in the topmost hopper, which gets smelted and transported using the bottom hopper into the chest on the left. Which often is a double chest at the bottom of a column of chests.

The optional hopper on the right can be filled with the fuel of your choice, I mostly use coal or charcoal, as I often smelt smaller quantities of items, and don't want to waste fuel.

The crafting table on the top is not necessary, but I find it to be a convenient location. If you want to be able to turn this furnace setup off, you can place a lever on the crafting table (or whatever block you have in this position), and it can toggle the entire setup.

Stackable item filter
This item sorter addresses some of the randomness with Hoppers in bedrock, which according to silentwisperer is due to presence a Repeater. The design is silent, as the hopper won't move due to the obsidian. The topmost hopper is the input hopper chain, the middle hopper (facing into the comparator) is the filter hopper, and finally the lower hopper is the one going into your chest.

The repeater is replaced with a piston, which needs to at some point face into an immovable block, like Obsidian, in order not to extend. This also make the circuit silent, and a little faster than the repeater option. In a single wide build this could be done as shown in the schematics, and with multiple next to each other one could switch the piston sideway, and add an obsidian block at the end of the chain.

Due to the three redstone dusts this filter will open up when there is more than 45 items, so with using only 4 named filler items, and 41 of whatever item you want to filter, it'll never overflow into filter next to it. So to prime it, fill the 4 rightmost hopper slots with one each of your filler items, and a stack of what you want to filter into the first slot. It'll then dripple down into the wanted 41.

Non-stackable item filter
The non-stackable item filter is basically the same as the stackable item filter, but instead of having a item filter hopper, it's moved one up and works directly on the input hopper chain. On realms/servers, it might fail every now and then, and due to that it's advisable to have 1 few of these next to each other just to be on the safe side.

The video above also displays this filter designs, along with various tidbits on item filters and designs.

Overflow handling
The item filters above handles overflow when filtering as the comparator output will be 3 strong when there is from 45-64 of the filtering items (given that you use 4 filler items). However, if the storage column/chests receiving the items fills up, it can back up and clog the system. And for some items, enough is just enough of that item, so therefore I've designed a simple (hopefully working) system to handle overflow in the storage columns.

In most filter variants there is a torch either directly powering the power to lock the hopper, or indirectly through another block. In the excerpt shown in the schematics this means that the hopper shown and the redstone lamp are both powered. In order to have a working overflow mechanics, I need to get away from this powering. Note that the input chain is above the topmost hopper in the second column.

The basic idea for the overflow is to replace the storage chest with an overflow hopper chain, and due to hoppers allowing items to flow down before sideways, it'll trigger the overflow hopper chain only when the hopper below is completely filled with items already.

Due to the overflow chain being above a chest, it'll not come in conflict with other chest, but go down the chain towards whatever overflow handling one chooses. Like destroying the items...

Complete item filter assembly
Here is shown the combination of the stackable item filter, with an additional overflow chain and the first chest storage combination.

The input chain is the topmost hopper chain (in the top row), and the overflow chain is the leftmost hopper chain (in the third row). The storage column itself is extended downwards using alternating hoppers facing left and right based upon the 2x3 schematics in the lower right of the schematics.

The item filter to be primed with 4 filler items, and 41 of the item you want to filter is in the second row.
