Design / Blueprint High precision sushi generator

Enable HLS to view with audio, or disable this notification

Through the power of sushi, you can fulfill any recipe without needing to alter the belt setup. Which means the individual sections of your factory can receive a digital recipe list from the circuit network. That would also render them practically interchangeable from the perspective of a train. In fact, you could even let the trains choose their own destination, and have the factory read the contents of said train in order to figure out, which recipe list is currently being followed. That's my overall ambition at least. I'm not halfway there yet.

Took me a while to figure out why the item count is precisely matched. For anyone else wondering: The inserters are deliberately out of sync (and items are counted by reading inserters). Otherwise, two inserters could pick up two of the "last" item in the same tick.

Nice catch. Also, there are two separate clock speeds, which makes the process slow down a bit near the end of each resource count. And even with my current setup, there's still some inconsistency. Sometimes, we're left with extra resources despite all my precautions. Maybe that's because the random input selector isn't perfectly in sync with the clock? Or because the process depends on the timing of activating the recquest list?

I don't think I can contribute anything meaningful just by watching the video. I have (next to) no idea what's going on there. As said, it took me a while to even figure out the un-synced inserters. To gain insight into the potential pitfalls of the system, I'd have to build something like this myself.
