Narrow channel for mixed ingredients (low throughput)

[hakuseki]

I wanted to assemble multiple science packs right next to each other with only one belt for input. Sushi belts are too wide since they must make a complete loop. Well, I couldn't figure out how to do it with belts, but here's how to do it with chests!

The filter inserters try to balance the contents of the chests supplying assembly machines (chests 1, 3, and 4 from the top). For example, if you place 50 turrets in the top chest, the inserters will swing until there are 14, 0, 18, and 18 turrets in each chest. This logic is applied independently for each item type, so you can easily distribute 5 or 6 different ingredients to the assemblers that need them.

How it works: The combinators multiply all signals by -1. Thus each filter inserter gets a positive signal for each item that has a greater count in its source chest than in its destination chest (ignoring chest 2).

Tiling: to continue downwards, overlap the top chest of the blueprint with the bottom chest of the existing layout.

Caveats: total throughput is limited to one inserter. Also, loading ingredients into the channel in the first place is not so elegant. For example, you can remove the top two assembly machines and insert into the top chest from three different belts with three filter inserters each configured the same way (red wire from belt to inserter; green wire from combinator

To load the inputs from belts, you can do something like this:

This ends up placing about 6 of each ingredient into the chests.
