What items can be farmed fully automatically?

After a little more than a hour looking up things and figuring out stuff, I think I have a list of all items you can make farms for. (Only the automatic farms). Here is the list and hope this helps.

Planted Crops

• Cacti - Cacti farm.
• Sugar Cane - Sugar Cane farm.
• Mushrooms - Mushroom farm.

Mob Grinders

• Iron - Iron golem farm.
• Roses - Iron Golem farm.
• Eggs - Chicken farm.
• Bones - Skeleton farm.
• String - Spider farm.
• Rotten Flesh - Zombie farm.
• Blaze Rod - Blaze farm.
• Ghast Tears - Ghast farm.
• Sticks - Witch farm.
• Glass Bottles - Witch farm.
• Glowstone Dust - Witch farm.
• Redstone Dust - Witch farm.
• Sugar - Witch farm.
• Assorted Potions - Witch farm.
• Gunpowder - Creeper/Witch farm.
• Ender Pearl - Enderman farm.
• Magma Cream - Magma Cube farm.
• Gold Nugget - Zombie Pigman farm.
• Gold Sword - Zombie Pigman farm.
• Slime Ball - Slime farm.

Cobble can be farmed through withers, don't forget that. Feathers can be farmed through a cooked chicken farm. Ink Sacs can also be farmed

That's all I can think of at the moment for autos that wasn't already mentioned by previous people.

The lists above are excellent!

But, this question was asked before Minecraft 1.8 so a few things have changed.

Now you can use Villager Farmers to automatically harvest and replant Carrots, and Potatoes, and Wheat. You can also automatically collect the Bread that Villager Farmers make with the wheat.

Another source of automated carrots and potatoes are from zombie mob grinders.

You can fully automate Pumpkins and Sugar Cane, but not melons. Any automation will break them into Melon Slices. So Melon Slices can be fully automated.

Villagers can also be farmed. Because you can have them automatically shipped away from the village and stored somewhere else so that more can breed. I manually do this right now but am building an automated system.

I've built a minecraft world that fully automates most almost everything I can think of. I made a video tour of this world that you see at:

I've built a 11x11 tower with a hopper floor, which feeds into a trap chest. The trap chest activates pumpkin and sugar cane farms. Chickens on the hopper level drop eggs, above that is a squid farm creating ink sacs, above that is a cactus farm, and above that is a zombie/creeper/skeleton farm that spawns them and pushes them out, they drop all the way past the farms onto the hopper floor and die. It's almost fully automatic, if not for the trap chest mechanism. Eggs, reeds, pumpkin, ink, cactus, potatoes, bones, arrows, rotten flesh and sulphur are constantly filling my chests.

I have just completed a fully automatic raw chicken and feather farm, it gives me 4 to 5 stacks of raw chicken for trading with the 4 butchers in a nearby village. the big problem is what to do with all the feathers!!! I based it on a well tried piston killing method, with all the drops collected and moved by hoppers with the addition of a sorter at the end of the row of hoppers, the eggs are lifted straight back up to the top with a droppervator into a row of hoppers which carry them back to the dispenser at the head of the row of hoppers, when the last hopper is full, the comparator next to the last one signals through a home made signal-to -pulse converter to kill all the birds, then after the pistons retract the signal goes to the front of the farm to start the reloading, simultaneously locking the hopper run, once the dispenser is empty, the circuit for the dispenser turns off and the hopper run is unlocked, and it works, at last after many an experimental hour on development.

New updates

Crops: Bamboo: random tick (player within a radius) / 0 tick (loaded chunk) kelp: ramdon tick Events: raid: AFK Ominous Banner Emerald Totem of Undying Saddle crossbow iron axe (potions, glow stone dust,...) witch again hero of the village (villagers throw junk at you)

A sort of cheating way is afk fishing enchanting books junk

snow can be farmed automatically, by using a snow golem with a piston to break the snow layer under it and fill into a hopper, which funnels into a crafting table to be crafted into a snow block, and funneled out using another hopper into a chest storage system.
