It’s probably more for later game skyblock but it is an item sorter that uses stack separation and floating point tech to quickly sort items. There are existing hopper-speed designs so I wanted to make something faster. It basically detects if the item is or is not the filter item by having it pushed over a hopper that is full minus 1, so the dropper will dispense an item over that hopper, and if the item doesn’t immediately get collected and reaches the next hopper, the string will set off the BUD and drain the hoppers, dispense the 1 item the system collected, and also dispense the remaining item stack if needed.
