Challenge: Can you do it without splitters or underground belts?

Challenge: Can you do it without splitters or underground belts?

I could, but then it wouldn't be as compact and would overproduce ingredients (unless I could also use circuitry, then maybe I could make it not overproduce)

[MassiveDynamic]

Can you do it for base rate of 5 red and 6 green?

[Optymistyk]

Can you do it for base rate of 5 red and 6 green?

So you mean 5 red to 6 green?

I could. But why? You always need 1 green per 1 Red science, so I don't see a point

You do in any vanilla science using both red and green.

What are those belt shenanigans for at the top right? I'm really new to the game..

Looks like 1 to 3 balancer with a few extra splitters without purpose.

No, it's the key part of this design.

The whole setup is built around the limited amount of iron gears that can be produced, those are then divided amongst the rest of the factory in certain ratios. The Inserter factory always receives 1/4th of the total gears going into the FIRST splitter. The red science also receives 1/4th. The belts receive 1/8th (1 craft produces 2 belts, so you need double the amount of inserter crafts). The excess gears going to the belt side of the FIRST splitter are routed back to that same splitter so they join the newly crafted gears to be split over the whole system again.

The amount of red/green factories are chosen accordingly to be able to keep up with the amount of iron gears available to them.

All in all I think it's a pretty unique and fun design. Drawbacks that I can think of personally are that first of all there is a lot of idle time on the machines, causing unneeded power draw and the odd science/minute that will result from this that might be hard to balance with the other sciences tiers unlocked later which defeats the idea of not overproducing. On the other hand, building a green science setup that fully utilizes every machine in it you end up with a pretty massive factory that is completely out of scale during the early game.

The excess gears going to the belt side of the FIRST splitter are routed back to that same splitter so they join the newly crafted gears to be split over the whole system again.

While I was mistaken in it being a 1 to 3 balancer (instead it's a 1 to 4 with 2 of the outputs routed to the same output), it does still have superfluous splitters in there. Only 2 splitters are really needed here, and it doesn't need the loop back to function.

Thank you so much for this, now there's more space for my chaos spaghetti elsewhere in my factory
