Tutorials/Cobblestone farming

Cobblestone farming uses a Cobblestone generator to produce cobblestone without damaging the terrain. Cobblestone generators work on the principle that when a lava stream comes into contact with water, the lava is turned into cobblestone. This fresh cobblestone then prevents the two streams from touching. When this fresh cobblestone is removed, the two fluids will produce another piece of cobblestone.

Many generator designs exist, but the most basic is a 10-block long trench with a water source block at one end, and a lava source block at the other. This will create cobblestone next to the lava source block.

One must be careful not to accidently create obsidian, which happens when water comes into contact with a lava source block (See Tutorials/Obsidian Farming). A basic understanding of fluids is helpful to prevent this.

Standard Cobblestone Generator
Standard generators have been around for quite a while. Their popularity, however, is limited because cobblestone is so readily available. Standard generators have the player mine the fresh cobblestone, which they then collect. The main issue with this type of cobblestone generator is that the item can fall into the lava, destroying the item. Even though cobblestone is a renewable resource, this greatly reduces efficiency.

Sample designs: It is suggested to use obsidian blocks behind the lava source blocks, as this will stop you from accidentally mining a hole in the back wall.
 * Fountain Style

This design features a lower chance of the cobblestone being destroyed by lava, but it is significantly larger.

Piston Cobblestone Generator
Pistons can be used to automate the cobblestone generator. Piston cobblestone generators work on the same principle as standard generators, but, rather than mining, a piston is what clears the fresh cobblestone or stone allowing the streams to touch once again. Piston cobblestone generators can be used in two ways, to create a large supply of cobblestone that the player can mine later, or to keep the cobblestone as blocks, which can be used for self-repairing structures.

As of 1.9, lava flowing into water from above creates smooth stone. Stone can be mined slightly faster than cobblestone, it can also be obtained as stone if using a pickaxe with the Silk Touch enchantment and gives self-repairing structures a different, more natural look.

Components
There are three basic components to consider in a piston cobblestone generator:
 * The Core. This part includes the water and lava that creates the fresh cobblestone.
 * A clock generator. This part sends a pulse to the piston that pushes fresh cobblestone out.
 * Optionally, Secondary Pistons. These parts move the fresh cobblestone further, allowing for more cobblestone to be generated.

The Core


The piston pushing the stone/cobblestone is always non-sticky.

This part can be very similar to standard cobblestone generators. The lava and water mix in front of the piston. One thing to consider is that the piston must be accessible by redstone. There is a hole at the end of the water stream which draws the water straight. When attached to a redstone clock, this will create a single row of cobblestone 13 blocks long (since the limit a piston can push blocks is 12 blocks).

The stone generator is rarely used without pistons, as lava needs to be directly above the stone generated. Lava must flow down into water flowing in front of the piston. Like cobblestone generators, it will make a row of stone up to 13 blocks long.

Redstone Clock Generator
A basic understanding of redstone is helpful but not necessarily required.

The ideal clock will send a pulse shortly after the stone/cobblestone has been created, making way for a new piece of stone/cobblestone. The generator can be toggled by placing a lever on the side of the block with the redstone torch.

This simple clock is created by placing a redstone torch onto the side of a block, with a piece of redstone dust on the direct opposite of this block. Note that the redstone torch must be attached to the side of the same block that will have the diode on it. The diode should have a maximum delay for a cobblestone generator. The connection to the pistons can branch off the redstone torch or dust.

Sample side view of the clock required for a generator: l x - d - x r - x - y  x - x - x (Ground)

x: a covering block such as dirt or stone d: a diode/repeater r: redstone torch y: redstone dust l: lever

note: the dashes do not represent spacings

Secondary Pistons
Since pistons can only push a maximum of 12 blocks, the core will only produce a limit of 13 cobblestone blocks. This can be greatly increased with secondary pistons that guide the row of cobblestone in other directions. In a way, it is a similar idea as the core piston in that it removes the fresh cobblestone in order for more to be created. Self repairing structures tend to use several secondary pistons and one or two cores.

Triggering a secondary piston can be done a few ways. The secondary pistons can be connected to the same redstone clock as the core, which periodically extend the piston. This can be annoying if you are working in the area as pistons make considerable noise. Alternatively, a Redstone Repeater can send a signal through the block which detects when a piece of cobblestone is present. This can then send a signal to a line of secondary pistons which trigger simultaneously.

How to make a smooth stone generator
This is simple to make and 90% efficient you need these items -lava bucket -water bucket -a lot of dirt(or any other block thats not flammable)

now its time to get started

make a 5x5 area out of dirt hollow it out put water on the bottom and put lava on the top and take out the blocks 1 block above the water to mine the stone blocks and make a collection area by removing the dirt block in the corner the water flows to and control the water by letting it go out one block then surround that one block of water and you have a collection area mine the stone blocks out then go to collection area to collect them(warning results may vary you may have to tweak with it to make it better)

Video Tutorials/Examples
This design is the easiest to build and the most basic. It is simply lava and water placed in the ground with a place to mine the cobble from.
 * The Most Basic Cobblestone Generator

This design offers a completely covered and compact version of a cobblestone farm. This design's size should minimize possible lag and includes a switch, to control production.
 * A Simplified, Fully Automatic Piston Clock Based Generator

This design is a very efficient cobble generator, doesn't lag your game, is very small, and fairly easy to build. Unlike others, this version has a built-in failsafe, so it never breaks.
 * Full-Auto Piston Generator with Failsafe

This uses a four sided repeater clock, but with uneven delay. The piston is retracted 5/6th of the cycle.
 * Piston generator

This compact design triggers when cobblestone is generated rather than using an external clock which means it provides the player fresh cobblestone much faster.
 * Cobblestone Detecting Piston Generator

This Generator is the version for Smooth Stone without clock for enhanced speed and reduced lag. (Smooth Stone can be mined faster, too)
 * tube.com/watch?v=4yc6yjE1d_w Smooth Stone Detecting Generator

This shows how secondary pistons move the row of cobblestone from the core. They trigger at every clock cycle.
 * Secondary Pistons

This shows how signals can go through solid blocks using repeaters. This will trigger independently of a central clock and is a viable way of setting up secondary pistons to minimize noise.
 * Block Detector

This generator uses no redstone and is quite efficient. It works using the 'tight' spacing block on the fence to let the cobblestone fall, while keeping you up.
 * No redstone
