Buffer


This block allows you to transfer items between pipes and tubes easily. It also combines stacks of items together to reduce lag.
You can fill it with items with pipes or tubes, or even manually, just like a chest.
If you put a wooden pipe, gold pipe, or basic logistics pipe next to the buffer, it will output one stack of items into the pipe every few seconds (depending on the number of empty slots - 5 seconds when empty, 0.5 seconds when full).
If you put a filter next to it, with the input side facing the buffer, it will output a redstone signal to pulse the filter at the same rate it sends items into pipes.

Automatic Crafting Table MkII


When you right click this you will see four main area. At the top, the input (9x5). At the bottom, your inventory. At the left, a 3x3 recipe area, and a single slot at the right which is the output. Here's how to use it:

• Set the recipe in the recipe area. Nothing will appear in the output slot, that's normal.
• Put items into the input area by connecting tubes (or pipes) to any side. Regulators may be useful here. Each side (and the bottom) has its own row of the input area.
• Place a filter or transposer above the crafting table facing down. Apply a redstone signal to this to extract the crafted item. Another will be crafted almost instantly, if the ingredients are available.
• If the recipe produces a container item, such as buckets (when water buckets are used in the recipe), they will go to the last, red-shaded row of the input area. They can be extracted from the bottom. Note that if this is full, container items will be destroyed!

New feature not shown in the above screenshot: There is a button that toggles between 1 and 64. When it's set to 1 (the default), no items will be crafted unless the output slot is empty. When it's set to 64, items will be crafted until the output slot is full.
They can also be rotated with a RP2 screwdriver, Buildcraft-compatible wrench (including Crescent Hammers and OmniWrenches), IC2 wrench or stone hoe.

The "C" button (not shown in the screenshot) clears the recipe.
The "OD" button (not shown in the screenshot) is for ore-dictionary support. After entering a recipe that uses the ore dictionary - for example, 9 copper ingots - click the OD button, and the ingots will start flashing between all the available types of copper ingots. In this mode you can make copper blocks from any 9 copper ingots, even if they aren't all of the same type. If you edit the recipe it will stop flashing.

If you have NEI, you can click the "?" button next to a recipe while the ACT2 GUI is open to select that recipe.

Black Hole Chest
(on Fast graphics)

It's a chest that holds infinite items. Simple, really.
Note that you can't navigate to pages that don't exist. In particular, you can't go to a new blank page unless the previous page is full. Also, when it unloads, it will compact its contents so there are no empty slots until the end.
The GUI still has some visual bugs - if you click on a slot that's wrong, it should update with the correct items.
Disabled by default due to potential OPness - see the config to enable. Even if not enabled in the config, it can be spawned by /give, creative mode, TMI or NEI.
If these chests lag too much in fancy mode, you can force them to use the fast mode graphics in the client's config (tubestuff.enableBHCAnim=false). You can also disable the black particles (tubestuff.enableBHCParticles=false). (Note: If you get lots of fast-moving white/grey particles, that's a graphical glitch where they aren't clipped to the inside of the chest; see below)

Does not drop its contents when destroyed, to prevent possible lag from having too many dropped items. This is not a bug.

Incinerator

Connects to pipes or tubes, and permanently destroys any items that enter it - like a lava pit, but easier to use and with no risk of spontaneous combustion.

Duplicator

This acts like a chest that always has a certain item in it. You can pull an infinite amount of this item out of the chest with wooden pipes or transposers/filters/etc, a certain number at a time.
There is no way to legitimately get this block, and only ops can place it in SMP, for obvious reasons. Intended for things like admin-built dungeons where you want to never run out of reward items.
Right click to open the GUI (again, you must be an op except in singleplayer) and put in the item you want to spawn. The number of items in the GUI is the maximum number of items that will be spawned at a time (eg with one pulse of a filter). Remember wooden pipes and transposers will still only spawn one item at a time.

Retrievulator

This block is the "automated retriever robot" that BrickedKeyboard suggested.
World texture is temporary. Any texture pack makers want to give me a better one? I really have no idea what this machine should look like...

The side with the bigger hole is the input. It should be touching the output side of a retriever from RedPower. If it's touching any other block, or nothing, it won't do anything.
The side with the smaller hole is the output. It should be touching any inventory, such as a chest or ACT2.

You can use a filter instead of a retriever, which usually isn't very useful.

Make sure your retriever is in "non-slider" mode!


The inventory has three areas - the "R" (retriever) area, the "T" (target) area, and that single lonely slot on the right that you won't need to touch (items go here temporarily on their way to the output inventory)
The T area should contain the items you want to keep in the output inventory. In this example, it will be kept filled with 63 grass blocks and 63 smoothstone.
The R area should contain at least one of each item in the T grid, and should match its layout. If that last sentence was confusing, the picture should show what I mean.
The retrievulator will move items between the R grid and the retriever, and apply redstone pulses to the retreiver, to keep the inventory stocked with the specified items. If the inventory already contains the correct items, it will spawn a "retriever jammer", which has no other uses, and place it the retriever to stop it from accepting any more items.

Walking over a retriever jammer will destroy it instead of picking it up.

Retrievulators can be rotated with either RedPower screwdriver. As of 51.0.0, they can also be rotated with a Buildcraft wrench, IC2 wrench or stone hoe. As of 52.2.0, any BC-compatible wrench will also work, such as TE crescent hammers and OmniWrenches.

The retrievulator will emit pulses more slowly if it hasn't successfully retrieved any items in a while. The minimum speed is 20 seconds per pulse. (new in 49.3.0)

Note: The T area now (as of 49.2.0) uses fake items, similar to Logistics Pipes. You can set it to request up to 127 of an item, even non-stackable items.
Right click to add items, and left click to subtract items.
Hold shift to add/remove 10 items at a time.
If you click with either button on an empty slot, you will set that slot to a copy of the stack you're holding.

Note: If the R grid and the retriever both contain an item in the same square, the retrievulator will not function. If neither contain an item, but the T grid does contain an item in that square, the retrievulator also will not function.

Note: Do not place retrievulators next to each other, as they emit a strong redstone signal that can power things through solid blocks, and might interfere with other retrievers. (Fixed in 49.3.0?)

Block breaker

When you put a tool in, this will break the block in front of it.


It acts like a player breaking a block, so it takes time and uses durability.

Liquid duplicator/liquid disposer
Liquid versions of the duplicator and incinerator.
For the liquid duplicator, you should put a liquid container item in the slot - eg a filled bucket or IC2 cell.

Online player detector
Turns green and emits a redstone signal when the player who placed it is online. Useful for servers which require you to turn off your machines when you're offline.

Storage blocks

From left to right, top to bottom:
Silver, tin, copper, nikolite, coal, redstone, blue alloy, red alloy, brass.
They work like the vanilla metal blocks.

There is also a charcoal storage block that looks identical to the coal one.

There is a config option to disable all of these at once, and another option to disable the vanilla storage blocks (coal, charcoal and redstone).

Nikolite and redstone blocks must be placed on top of another block or they will fall.

As of Minecraft 1.5, redstone blocks are now powered redstone blocks, made by crafting vanilla redstone blocks with sand.

As of Minecraft 1.6, coal blocks are now coal brick blocks, made by crafting vanilla coal blocks with stone bricks.

Tekkit Science series by ProfessorLotte:

Right clicking opens this GUI. If you are op (or in singleplayer) or the owner of the chunkloader, you can change the size of the loaded area without breaking and replacing it (which would make you the owner).
The green button expands the area loaded by this chunkloader by one chunk, and the red button shrinks it by one chunk.
As you can see, there is a limit on the number of chunks that each player may force to be loaded. In singleplayer, or if the owner of the chunkloader is an op, there is no limit.

It displays four things.
First, you can see a blue or orange box around all chunk loader blocks, even through walls. This is useful if you bury your chunkloaders and forget where they are, or if somebody tries to cause lag on SMP.
Blue boxes indicate chunkloaders you own, while orange boxes indicate chunkloaders owned by someone else. Orange boxes are only visible in singleplayer, to ops, or if they have been enabled in the server config (chunkloader.hideOtherPlayersLoadersInF9=false).

For the rest of this section, a "visible chunk" means a chunk that is being kept loaded by a chunk loader you can see with a blue or orange box; if you can't tell a chunk loader is there, you can't tell which chunks it is keeping loaded.

Second, a translucent blue border will be drawn around the chunk you are standing in, if it is visible. This border cannot be seen through walls, and helps to see whether your machines are all in the same chunk.



Third, a green line will be drawn in each corner of each visible chunk.

Fourth, a translucent red square will be drawn above your head height, in each visible chunk. It will be drawn once for each chunk loader - that is, if two or more visible chunk loaders are keeping the same chunk loaded (and thus the chunk is counting multiple times towards your limit) the red square will appear darker.
This *is* visible through walls and ceilings, so that you can see it indoors.

If you set chunkloader.useFuel=true in immibis.cfg, anchors will require fuel to run. Anchors without fuel will be treated as if they don't exist - so they won't appear in F9 or contribute to your quota. (This also means you can set them to a larger area than you're allowed, and it won't be reset until you put fuel in)

If you set chunkloader.allowFuelPiping=true in immibis.cfg, then automation mods (such as Buildcraft pipes, RedPower 2 tubes and ComputerCraft turtles) will be allowed to insert fuel into anchors. If it is set to false (which is the default), they will be blocked (using ISidedInventory).

The available fuels and value of each fuel is configurable in immibis.cfg. This is mainly intended for server admins.

The amount of fuel used is scaled by the number of chunks, so a 3x3 loader will use 9 times as much fuel as a 1x1 loader.

Default fuels:

Item Time per item (1 chunk) Time per stack (1 chunk)
-----------------------------------------------------------------
Coal 10 min 10 hr 40 min
Charcoal 1 min 1 hr 4 min
Redstone 1 min 1 hr 4 min
Ender pearl 15 min 4 hr (max stack size is 16)
Magma cream 15 min 16 hr
Eye of ender 30 min 32 hr
Dirt 1 sec 1 min 4 sec
Cobblestone 1 sec 1 min 4 sec
Smoothstone 3 sec 3 min 12 sec
Netherrack 4 sec 4 min 16 sec
Nether brick 10 sec 10 min 40 sec
Glowstone dust 2 min 2 hr 8 min

All of these commands are only available to operators.

• /dimanc getquota <username>
Tells you the current and maximum loaded chunks of that player.

• /dimanc override <username> <number>
Sets a quota override for a specific player, equivalent to setting it in the chunkloader.playerQuotaOverride section of immibis.cfg. This does update the config.
You can also use "unlimited" (without quotes) instead of the number, or "default" (which removes the override)

• /dimanc setfuel <ID> <time> <unit>
Sets a fuel item. ID is the item ID, and time is the amount of time. Unit is a multiplier for the time - it can be "sec" (seconds), "min" (minutes), "hr" (hours) or blank (ticks).
Example to make stone last for 5 seconds: /dimanc setfuel 1 5 sec

• /dimanc setfuel <ID>:<meta> <time> <unit>
Same as above, but with a specific metadata/damage value.

• /dimanc setpipemode allow
Enables automatic fuel insertion and updates the config.

• /dimanc setpipemode block
Disables automatic fuel insertion and updates the config.

These are the valid locations for bookshelves:

The bookshelves can be up to 1 block below or 1 block above the Enchanter.

This makes creepers just disappear instead of exploding, so your terrain is safe (because vanilla isn't like Bukkit, they don't hurt players either). Suggested by Olaf464 on IRC for his server.

Officially discontinued as of 26/09/2012. Old versions are still archived at the old download pages (see top of post).
Yet another very unimaginatively-named mod. This one will keep all chunks with at least one tile entity loaded, ignoring chests, signs, end portals, mob spawners and record players. It's just for my learning about IChunkLoadHandler, but I thought someone might find it useful as a compromise between keeping the entire map loaded (as some servers do) and the default chunk loading behaviour.
Requires Forge.

This isn't recommended, because I realised how long-winded and broken its transmutations were. I might change the recipes later and un-un-recommend it :

This mod adds recipes to EE for transmuting items using the Philosopher's Stone. Note that it does not use the learning system like the transmutation tablet does. Don't bother trying to use these recipes in normal crafting tables - they're much more useful for automatic ones.

It reads the item and block IDs from mod_EE.props and does not interact with EE in any other way.

If you find any missing recipes or there's no way to transmute X to Y with just the pstone, post it here. I expect there to be quite a few items or conversions I've overlooked, given the number of recipes in this mod. I suggest you use CraftGuide to see the list of recipes added.

These recipes are not related to the old v5 or v4 recipes. The path for transmuting cobble into diamonds is: (and it's a LOT longer than in v5 or v4; this is the reason I don't recommend using this)

Download, installation, requirements
Requires EE2, and nothing else except for EE2's requirements.
Put the zip in your mods folder.

It also adds some new fuel transmutation recipes. There are few enough that I'd draw a diagram if I knew what software people normally use for drawing diagrams. Here's a complete list of fuel transmutations:
Again, there are way too many matter transmutations to list them all. Try CraftGuide or NEI.
