Ah yes, you gave me a good piece of advice @Amaranth, hoppers do have the functionality of outputting a fixed amount at a time.
I will need to investigate this further but basically, i can possibly work with this mechanic in such a way that i always ensure batches of 9 or at least divisible by 9 are sent to some autocrafter that can select the appropriate recipe depending on the ore.
Or at the very least, i can somehow sort all those tinies in such a way that i have evenly divisible by 9 amounts of them at some location.
Sort of a sensor setup that detects when only a remainder stays in a hopper for some time and thus sends it someplace else.
Or, I can at least work with said hoppers in such a way that a mass storage over a hopper sends 9 items at a time into a “forgets filter when empty” item barrel and a single point of conversion from tiny to regular. Perhaps through a boxinator.
Either way, didn’t consider hoppers having the capability you just mentioned.
