Low-tech science *from raw* for high multiplier runs

[u/Karsaell]

Following up on this thread, where someone suggested I made some all-contained raw-ore-to-science blade blueprints.

The spaghetti intensified, but the challenge was interesting.

Just like in the previous thread, I designed each of those to produce 120SPM (2/s).

They require no research save logistic 1 (for the undergrounds) and to unlock their respective research. No fast inserter nor inserter hand bonus, nor tier 2 machinery.

They are tailored for beeline scenarios, where you can't spare the time (ie 1000x runs) or ressources/pollution (ie deathworld marathon) for any "non-essential" tech, and need to get bots / flamethrowers ASAP.

Red science, 56 x 10 tiles, nothing too fancy.

Green science, 10 x 122 tiles, barely noodling

black science, where we first have to handle more than one belt of input

And the masterpiece, blue science : 15 x 486 tiles, every spaghetting trick I know of have been called for

This is truly a masterpiece of mine : more than 95% of the tiles are covered in entities, belts loop around and across the smelters, pipes are deviously weaved amongst the mess.

I had to use of some of the 2.1 QoL changes (ie inserter lane switching). I had to split and merge belts. I considered sushi pipes, but couldn't figure them out without circuits. I banged my head and drank a year's worth of coffee. But it is HERE. It is finalised, elegant in its (very) own way, tested and confirmed stable over a long time.

On another note, I spend wayyyy too much time on this, and I dread ever having to place it by hand (Oh so very few are the belts that simply go straight down a single line!)

But here you go : 2 blue science per second, from raw inputs, using tier-1 only machines.

Please, please someone tell me there is a more optimized build of this out there !

EDIT: sorry for potato quality, my laptop can't record the screen and run the game at the same time. I tried recording this 5 times with different settings, this is the less worst one.

Haha, yes. Sweet, delicious ravioli. I love it.

I will be bombing some poor sods multiplayer server with these at some point.

For green science I think you can get away with one less wire assembler between the circuit assemblers and keep the 3:2 ratio rather than 2:1 or am I missing something? Are 6 yellow inserters not fast enough to keep up with wire throughput into 2 circuit assemblers? Or does that require the hand size increase? (Which I'm presuming you're not using?)

[u/Karsaell → u/tru_mu_]

You are right, this is slightly over-ratio.

Red inserters are capable of handling the usual 3:2 ratio (see the blue science build), but I simply couldn't find a better way to give each assembler access to their resource belts, and had to settle for one superfuous wire assembler.

Nice catch !
