The bedrock breaker will, when sufficiently powered, gradually grind away at the bedrock blocks in front of it with a 4-block range. When each block is consumed, it will expel a piece of bedrock dust, which can be used to make the highest tier of tools or shafts and gears - bedrock. This machine's operational speed goes up as the input speed does.

The fermenter is how you actually produce the ethanol for the engines that require it. To make yeast, place sugar in the top slot, water in the middle, and dirt on the bottom. To make sludge, put yeast on top, plant matter in the middle, and water on the bottom. Dry that sludge out in a furnace, and you will get crystals of ethanol. This machine's operational speed goes up as the input speed does. This machine is very temperature-sensitive, and excessively low or high temperatures will slow it down or even kill the yeast.

The grinder does exactly what its name suggests - it grinds things. Stone to cobblestone, cobble to gravel, gravel to sand, that sort of thing. It also plays a critical role in the lubrication of gearboxes - it grinds the canola seeds into an oil usable as lubricant. This machine's operational speed goes up as the input speed does.

The floodlight creates a beam of light that illuminates everything in its path until blocked by an opaque, solid block. Perfect for lighting up large spaces where point-source light sources like torches will simply not cut it. The floodlight requires %dW of power for each light level produced, to a maximum of 16.384kW for light as bright as direct sunlight.

One of the most powerful and expensive of the machines, the heat ray creates a beam of fiery death and destruction for as long as its range allows. While it is hard to supply enough power to turn the thing on, let alone unlock some of its more powerful capabilities, it, fully powered, is capable of burning down a biome kilometers away if you let it. Extra power to this machine, in addition to increasing range, also increases the range and strength of its ability to melt rock, light TNT...

The boring machine is rather interesting. It will dig tunnels in the direction it is facing for as long as you like. With the GUI, you can control the tunnel shape from a number of designs, and, if the cobblestone and dirt spewing out of the machine bothers you, disable the item drops. Harder materials require more power and torque to dig - %dW per hardness points of the blocks in front of it, and up to %d Nm of torque to cut through the harder materials. The borer will ensure that the tunnel roof does not collapse by replacing sand and gravel.

The pile driver repeatedly impacts the ground to break it apart, digging a deep, narrow shaft. This shaft will go through any liquids in its path, and will go through everything but bedrock. Multiple impacts are required to break some harder materials, and the vibration will dislodge things like paintings, uproot saplings, and disorient players. Beware: Being in the path of the mining pile will end exactly as you may imagine. This machine's power requirements go up the deeper it digs - %dW per meter depth.

The potion aerosolizer has nine internal tanks which can store up to 64 bottles of potion each. These effects are dispersed through the entire room the machine is in, and applied to all entities within. Filling more than one slot with the same potion type will result in upgraded effects.

This machine will, when its enormous power requirement is satisfied, emit a beam of solid, tangible light which can be walked upon and will support any mass placed on it. Nothing can destroy this beam, but it will be blocked by any non-air block. Note that it requires bright light above it - or a view of the sky - in order to be able to make the beam.

The extractor is used to get more material out of ore. First, it grinds ore to dust, then mixes it with water to form a slurry, then presses that slurry through a filter to obtain a liquid solution, then burns the result to obtain ore flakes. These flakes can be smelted in a furnace to obtain a unit of the ore's material. Each stage in the extractor has a 50%% chance of doubling the output. The machine's requirements are complex and vary from stage to stage, but a supply of water and %d Nm of torque at %d rad/s will run all four stages.

The pulse jet is a powerful furnace. While it will not smelt the ordinary recipes, it will melt obsidian into glass that is immune to TNT, melt scrap metal and tools back into ingots, and make steel more efficiently than a standard furnace. It will get VERY hot, and will ignite nearby flammable materials - keeping it cooled with water is a necessity. While there is no minimum power requirement, the jet requires high shaft speeds. The pulse jet consumes jet fuel to operate, and a rather large amount of it. This machine receives power from below.

The pump will, when provided with power, will suck up liquids from the surrounding area and pump them into pipes, for transport to a machine that can use it. Water is often used as coolant, while lava is more often pumped to a reservoir for convenient access. Excess power to the pump generates pressure, which is essential for the operation of sprinklers.

The reservoir is simply a tank for storing liquid, either water or lava, with a maximum capacity of %d cubic meters (buckets). It can be right-clicked with a bucket to add or remove liquid, and if it is full of water, glass bottles can be filled from it.

The fan emits a stream of air that will push entities around. With greater input power, heavier entities can be moved, and all entities will accelerate faster. A minimum of %dW of power is required, and power levels greater than %dW of power will have no increased effect due to airflow limitations.

The compactor is capable of compressing coal until it becomes anthracite, then prismane, then lonsdaleite, then diamond. Each stage will require four of the input items per unit output. All steps require enormous pressures of %dkPa and temperatures of greater than %dC to take place. The compactor will gradually heat or cool depending on its surroundings, and pressure is built up by applying high torques.

The auto-breeder will lure in animals, and when they get close, feed them until they feel like breeding. With this machine, you can quickly amass large herds. Each animal has its own desired food item; without that item, the machine will fail to attract or feed the animal. Wolves, for example, particularly like raw pork. The food item will be consumed when the animal enters breeding mode.

The bait box will attract or repel mobs of all kinds, provided it contains the appropriate items to do so. For example, Endermen are attracted by grass blocks and the opportunity to take them, but are repelled by the faces on soul sand staring back at them. These items are not consumed.

The firework machine will, when given the appropriate ingredients with which to make fireworks, craft random fireworks out of the possible recipes and launch them automatically. When given pre-made firework stars, it will use those preferentially. With excess power input, the machine is capable of conserving ingredients and thus getting far more than one firework out of the same amount of ingredients.

The fractionator distills various items and refines them into jet fuel for use in some of the engines and machines. Jet fuel requires tar, netherrack dust, coal, blaze powder, ethanol, and magma cream. Additionally, ghast tears are used as a solvent, but are not consumed like the other items. Fuel lines connect only to the top of this machine.

The Ground-Penetrating Radar is capable of reading the densities and other properties of the blocks below it, and from that determining what blocks lie below. This allows it to draw a cross-sectional map of caves, underground structures, and other materials. Larger power inputs will give it a wider field of view, topping out at 82 blocks wide.

Tired of blowing up your compactors and steam engines by overheating them? The heater will heat itself to a temperature you specify, and when placed below a machine, will warm it to a temperature near its own. The heater will consume any fuel that the standard furnace can, with stronger fuels providing more heat, up to 800C from one lava bucket.

The obsidian factory will mix piped-in water and lava to produce obsidian. Be careful; if the machine is left full of only lava too long, it will start to overheat and will eventually melt.

The player detector does exactly what its name implies - when a player comes within its configurable range, it will emit a redstone signal. The maximum range is determined by the power input, and the reaction time of the detector - the delay between a player entering a range and the signal output - is dependent on the speed input.

The spawner controller hacks into the functioning of a monster spawner, allowing you to either shut it down completely, or to adjust the spawn rate as you see fit. The minimum allowable spawn rate is determined by the power input.

The sprinkler will, when supplied with water, spray it out on the blocks below, watering crops and speeding up their growth, hydrating farmland, and extinguishing fires. Higher water pressures - created by larger power inputs to the pumps - result in increased range.

The item vacuum draws items and XP orbs towards it, and will absorb them into its internal storage when they get close. To extract the stored XP, right-click it with a screwdriver while sneaking.

The woodcutter will cut away at the trunk of a tree, causing the rest of the tree to collapse. In particularly densely forested areas, this will also knock over some adjacent trees; in jungles, the foliage is so dense that the machine automatically compensates and only cuts down the center of the tree to avoid biome-wide destruction.

The engine controller is as simple as it sounds. Simply place it below an engine, and apply redstone power, and the engine will shut itself down.

The mob radar can detect mobs in a large radius around it, and is unobstructed by blocks in the way. It will display their positions on the NSEW plane, signified with the appropriate icon. If you have a motion tracker in your inventory, the radar will also render a HUD of sorts to alert you to mob positions near you.

The coil winder is used to wind up coil items, to store mechanical energy for later use. It can also use previously-wound coils as an energy source, and provide a small amount of power (%d N/m at %d rad/s).

The TNT cannon fires primed TNT either with a given velocity (specified by speed, launch angle, and compass heading), or to a specific target coordinate. It requires a continuous supply of TNT to continue operation. It requires higher torques to fire at steeper angles, more speed to fire faster projectiles, and more power to reach farther targets.

The sonic weapon is a ranged defense weapon designed to protect against hostile mobs and players. At higher and higher volumes (made possible by higher input torques), it can cause more and more debilitating effects on those in its effect radius, from confusion to blindness to drowning to death. This machine follows the inverse-square law, and the severity of its effects decrease accordingly.

The blast furnace is the main way to make steel. Simply supply carbon (in the form of coal) at the left, gunpowder at the bottom-left, and fill any or all of the middle nine slots with iron ingots. Heat the machine to %dC to start the alloying process. The machine will operate more efficiently with more slots full of iron, and will give higher bonuses (up to a 49%% chance of a bonus with size up to 100%% (11%% chance). Note that the coal is not fuel - an external heat source is required.

The force field emits a solid sphere of energy that repels all hostile mobs and projectiles. Note that it is only solid in one direction - threats may leave but cannot re-enter. However, due to the large magnetic field, arrows will be diverted even if launched from inside the sphere. This machine needs a clear view above it equal to the selected radius.

The music box is essentially an integrated noteblock circuit. Simply program it with music - either using one of the demo tracks or by writing your own, and give it power to run the music. A redstone pulse will cycle the music once; for looping music, use shaft power.

The mob harvester is designed to kill mobs as if a player was, so that normally player-only drops (such as Blaze Rods) can be automatically farmed. The machine will deal damage to mobs directly above it, with the amount depending on the power input.

The projector, designed to be paired with CCTV, outputs an image against a wall. Note that the wall must be 6 blocks wide and 5 blocks tall, and must be unobstructed.

The railgun is a very powerful defence weapon. It uses strong magnetic fields to accelerate a heavy metallic projectile at the target, dealing very large amounts of damage. Note that more massive projectiles deal much more damage, and can destroy large areas of terrain. The railgun will automatically target the nearest visible mob; for maximum efficiency, mount it where it has a clear view of the surrounding area. You may also invert the railgun to target below itself rather than above.

The silver iodide cannon is used to control the weather. It has a built-in light sensor to determine the current weather and if set to do so, will fire the appropriate chemicals into the air to alter it. Note that it has a cooldown time, and must have a clear view of the sky.

The item refresher keeps nearby items from despawning. Note that items that have been maintained for a long time will immediately despawn if the machine is destroyed or loses power.

The cave scanner functions much like a laser 3D scanner. It sends pulses into the ground and can detect the interface between air and other blocks, which it will render in the world. This allows you to map caves from the surface. Its field of view is 16 blocks by default, and can be moved around by right-clicking the block. Right-click will push it in the direction you are looking, and shift-right-clicking will push it in the opposite direction you are looking. Caves are color coded based on depth.

The scaleable chest allows you to store your things in a small space. Its inventory size scales with the amount of power it receives, up to a maximum of %d stacks. If the power input drops or is lost while there are items in the now-removed slots, they will remain hidden and inaccessible until sufficient power is restored.

The flooder is designed to fill a depression with liquid piped into it. Each bucket worth pumped in equates to one placed liquid block. It will fill the lowest layers first.

The smoke detector will sound an alarm when it detects a nearby fire block, and will also beep occasionally when the coil powering it is running low.

The firestarter allows you to ignite flammable materials in a large radius, and is therefore very effective at clearing areas in forests or tall grass. Due to its ability to ignite creatures, it can also serve as a powerful, if rather dangerous, form of defence.

The freeze gun is a nonlethal defence weapon. It automatically targets threats, and will freeze them in a block of ice, completely immobilizing them without causing them other harm. Ice is more effective ammunition than snowballs. Like the Railgun, this machine can be oriented upside-down and is most effective with a clear view of the surroundings. Note that frozen mobs can still attack if approached.

The magnetizer uses a rapidly rotating shaft to create a magnetic field inside a shaft core. This is one of the critical components of an AC Electric Engine.

The containment field is complementary to the Force Field - while that keeps things out, this keeps them in. Note that hostile mobs which fire projectiles, like Skeletons and the Wither, can still hit targets outside the field without leaving it themselves. This machine needs a clear view above it equal to the selected radius.

The CCTV monitor is how CCTV cameras are viewed. Simply add 3 dyes as the color code - matching one of the existing CCTV cameras in the world - and shift-right-click it to use the camera.

The CCTV camera allows you to see areas that you would otherwise not have safe access to visit yourself. Simply provide it a charged wind spring and three dyes as a color code, and you can view the world through its lens with the aid of a CCTV Monitor. To exit camera mode, press "\". The camera can be reoriented with a screwdriver (shift-clicking for inclination).

The steel purifier is used to transform basic low-grade steel into pure HSLA steel for use in machines. Like the Blast Furnace, it requires gunpowder and temperatures over %dC.

The laser gun is another powerful defence or offence weapon. Like the RailGun, it targets the nearest mob or non-whitelisted player, and its beam sweeps the area, starting fires, melting rock, and generally causing havoc.

The item cannon can fire items across the map without harming them, which allows for near-instant long-distance item transport. Note that you must enter the coordinates of another item cannon to receive the items.

The friction heater is a tool to warm up a standard furnace without fuel. Higher torques and speeds mean higher temperatures, but beware: spend too long at high temperatures and you can melt the furnace entirely. Also of note is that high temperatures can speed up the furnace operation.

The land mine is a trap that can be laid up to one block underground. It requires a wind spring, and as its charge depletes, the risk of spontaneous detonation increases. Additional effects can be added by placing TNT, blaze powder, spider eyes, or glass in the right slots, and more gunpowder in the left slots increases the explosive force.

The bucket filler takes in liquid on the sides and empty buckets in the top, and automatically fills them. It can also be used in the reverse; full buckets can supply liquid.

The block cannon can fire blocks as projectiles, allowing you to make a large mess of your target. To launch liquids, put in filled buckets.

The aerial camera allows for you to see a large area as it would appear from high above, and therefore know the positions of exposed mobs and blocks. Like the CCTV camera, it uses a windspring and a 3-color "channel code".

Mirrors are crucial for the solar power plant to function. More mirrors means more power. Note that they require a clear view of the sky, and work at reduced efficiency if the sun is not at full brightness. Additionally, mirrors can break if heavy objects land on them.

The self-destruct machine can detect when its power supply is damaged, and unleash all sorts of destruction under the assumption that the base it resides in has been damaged or destroyed.

The cooling fin draws heat away from machines to help keep them cool without the need for advanced water piping systems.

The worktable is the crafting grid on which all machines must be crafted, with the exception of the Blast Furnace and the worktable itself. Simply use it as an ordinary crafting table. To actually craft the products, give it a redstone signal or click the item in the right hand side. The workbench is also used to recharge spring-powered tools. Simply put a new spring and the tool in the left slot, and take the products from the right. Unlike a crafting table, the workbench stores its contents.

The air compressor converts shaft power into pressurized air, which can be carried out via conductive piping to BuildCraft machines. If given excessive amounts of power, it can and will explode. Violently.

The pneumatic engine uses a turbine to convert pressurized air into shaft power.

The display screen is used to display text on a holographic screen, for things like server welcome messages.
