Batch Crafter

Set a recipe in the grid (click: they are samples, not used up); the result shows on the right. It crafts by itself from whatever reaches its storage (by hand, hoppers or a pulling upgrade), in any order: every 10 ticks it makes a batch of up to 16 crafts, depending on ingredients, output room and energy (20 EU per craft). Recipe leftovers (empty buckets...) go to the lower slot. A redstone signal pauses it (the inverter upgrade reverses that) and a comparator reads how full its storage is.
