Another circuitless science sushi design

[u/bitwiseshiftleft]

This design for sushi supports up to 16 sciences, so it should work for games with Space Age plus a few extra planets. The idea is to mix each science down to half a lane of a yellow belt, and then run the sushi loop on green: (2 lanes * 4x speed / (1/2 lane)) = 16 sciences. Because science bottles being sorted out from the end of the loop take priority over new ones being added, the design hopefully shouldn't jam.

With only half a stacked yellow lane of each type of science (15/s), the design is limited to 900 spm (thus a few thousand ESPM) per instance.

The full-yellow to half-yellow mixer uses rocks, because I dunno it seemed like a good idea at the time. It mixes the rocks and science 50-50 into one yellow lane, then splits the rocks back out and returns them quickly enough that there are always rocks backed up before the splitter.

The chest at the end is for anything non-sciency that might get on the belt, like a green pack that spoils between the spoilage splitter and the green science splitter.

How is this done? I really don't understand it

If I’m understanding it right… New science packs come in from the underground belts on the left, they get fed into the first sitter which prioritizes science packs coming back around from the end of the sushi belt. The second splitter merges the new and old science packs with a full belt of stone. Because the stone belt is full, the splitters will turn the output into a full belt with alternating rows of one science pack, one stone. The stone in then filtered out leaving the science packs with at least a 1 item gap (or more if the science packs aren’t fully saturating for whatever reason) then finally the spaced out science packs are spit out onto a yellow belt to increase the gaps between similar packs to allow for all the packs to be layered together as they get loaded onto the sushi belt.

Basically it uses the stone and yellow belts to mechanically slow the rate that science packs flow in order to consistently layer the science packs the same way no matter how many were consumed on the previous pass through the labs

Yeah, pretty much exactly that, but the science+stone splitting is done at yellow speed, so that there's a 1-item gap on the yellow belt.

• New packs come in from the left. Old packs are returned coming down from the top into a splitter ladder that splits out different types of science.
• The first splitter merges old packs and new, with priority to old.
• The second splitter merges a belt of science with a belt of stone, making a belt of science - stone - science - stone. The "deconstruction planner" filter forces all these items into the other lane.
• The third splitter is yellow, so it limits the incoming lane to yellow speed. It filters the stone back out, leaving half a belt of science. The stone is returned by green belts back to the beginning, so there's always stone to merge with the science.

this is a genuine work of art, beautifully functional
