Armadillo silverfish slime farm

A slime farm that needs no slime chunk and no swamp. Six armadillos curl up on a floor of 36 campfires because a zombie in a boat keeps them scared, and splash potions of infestation turn the damage they take into silverfish. Sticky pistons drop the silverfish onto the campfire floor, splash potions of oozing make every dying silverfish leave slimes behind, and the slimes burn on the same campfires. 38 hoppers under the floor carry the slimeballs into two double chests. The farm runs on brewed potions instead of spawn rates, so the biome and the light level do not matter and it works underground or over water. Nothing near it may be stone, cobblestone, deepslate, stone bricks or the mossy versions, the silverfish hide in those blocks.

Get the zombie into the boat before the armadillos go on the campfires, and take the leads off them, otherwise they unroll and burn to death.
Set both repeaters to 2 ticks, the sticky piston never opens if you leave them at 1.
The observer at 6:12 looks like it faces the wrong way, it is right as long as it points down, and it goes against the comparator on the left seen from the middle of the farm.
Slimeballs bounce out of the pit and despawn, so build the walls a block higher, dig the pit a block deeper and run a hopper minecart around the outside.
Splash potions of oozing and infestation last 3 minutes flat and cannot be extended, and the farm spends one oozing potion per cycle.
More armadillos give more silverfish, but the extra ones die to cramming before the pistons release them, so the slime rate stays the same.
