It's a painfully dark dimension (you will get damage when it's dark), a mining dimension that is. This should partially answer your question. Look out for the holes in bedrock... Craft a jetpack first. Search for the semi-stable ingots nuggets recipe before crafting. The unstable ones will explode after 10 seconds when crafting them. This will omit any armor and will kill you.
 
Have fun.
 
Edit: Oh, I forgot: mobs are overpowered there and spawn regardless of the light level. Only magnum torches suppress that.

When you first enter the deep dark, you are in a lit room, high above where all the good ores are. You could actually deploy quarries right here. They'll get lots of cobble first, but get to the good stuff eventually.

Well, the easier solution is Deep Storage Units for the mass items. But since you'll want to go to the Deep Dark eventually, it's not a bad idea to start making Compressed Cobblestone with your first Quarry.

also good to know is that a quarry won't connect to itemducts and a tesseract won't connect to BC pipes (in fact, the BC Pipes will connect, but all the Items get spit out).
 
you'll want to use tesseracts in mid-late-game to teleport power to your quarry and to get the items directly to your base...
(in endgame you'll probably use MFR-Lasers for ressource-gathering)
 
You have to use a buffer chest in that case
I prefer the following setup to support a quarry:

Greetings, Tekkiteers!
 
When I started using the Buildcraft Quarry, I ran into many small problems and annoyances that were not covered by any wiki or guide. So now that I have largely mastered that art, allow me to share my insights in a concise and (hopefully) compact manner.
 
1. Why Quarry?
Mining is tedious. Really tedious. It may be exciting to hunt for The Shiny at the start, but after doing it over and over again, it eventually loses its luster. Especially when you need to ramp up your production in mid-to-late game to feed that ravenous machinery. There will come a point where even for the most medieval of us, a robot that does the manual work will be a welcome relief.
Buildcraft has you covered. The BC Quarry is a machine for strip mining, that means it will remove (almost) anything in its path, block for block, layer for layer, until it reaches bedrock or an obstable that it cannot mine.
 
2. Make One!
You will be ready to make a quarry once you acquired 11 diamonds, 8 gold ingots, 28 iron ingots, 28 cobblestone, 1 redstone dust and 30 sticks of wood. Most of that goes into crafting BC gears, and the rest into a diamond pickaxe. All of this will be consumed in the making. As always, I rely on your ability to use NEI or the wiki for the actual recipe.
 
3. Power It!
The quarry runs on Minecraft Joules (MJ). In Tekkit, use any kind of Redstone Flux (RF) production and connect the quarry via Thermal Expansion conduits, which will automatically convert to MJ. It is highly recommended to use at least one energy cell as a power buffer, and using at least Hardened conduits and cells. The quarry uses lots of power, so Leadstone-level gear is too weak. Using Redstone-level is recommended. A small, early Yellorium reactor will power a quarry easier and quicker than any other setup, but you are of course free to design your own.
 
4. Place It!
As a quarry will strip-mine, you may want to place it out of sight from your home/base, to avoid looking (or falling) into a square pit later. On the other hand, you might want to use it to excavate a space for your future underground base, and cover the pit with a filler later.
Note that when placed and powered, the quarry will start building a 5 block high frame in front of it, inside and below which its mining arm will then operate. All blocks obstructing this space or the frame itself will be destroyed (not mined!), so take this into consideration. Especially make sure to not place your power source or any related machinery inside the frame area.
 
4.1 But Where?
If you dislike disfiguring the Overworld with large rectangular pits, you could opt to disfigure a random Mystcraft Age instead. Choose one you don't like, but that is safe enough for you to do maintenance in if needed. Or quarry the Nether right away - instructions on the special requirements for this included >further down in the thread.
Or just place it in the Overworld, but far away from your base. No matter where you decide to set it up, keep in mind that the Quarry does its own chunkloading. So as long as you put the power feed and output processing within one of the loaded chunks, you should be fine. But better check chunk boundaries to be sure.
 
4.1 Landmarks
If just plonked down, the quarry will default to a 9x9 space right in front of it. You can modify this area with Landmarks, which are just Redstone Torches re-crafted with Lapis Lazuli. Landmarks are glitchy, so don't be surprised when they malfunction. It will often suffice to just repeat what you were doing, or moving everything by one block, to make them cooperate.
Place three Landmarks defining a rectangle, all on the same height level, to claim the area you want to quarry out. You are marking the lower corners of the frame this way, so keep the block destruction in mind. Once all three necessary corners are marked, right-click the middle Landmark (I think any of them works, but middle works best). Red lines should connect them and visibly frame the rectangle you defined. If not, check if you actually made a rectangle or maybe went off by one block. Try breaking and placing all Landmakrs again. Also don't right-click before all are set. Keep in mind that the frame will extend to five blocks above the Landmarks. The maximum space possible is 64x64 blocks for the frame, i.e. 62x62 blocks enclosed.
 
4.1.1 Landmark placement beams
It may become tedious to correctly place Landmarks for larger pits. You can get some placement help if you apply a Redstone signal (Lever or Redstone Torch will do) to an inactive Landmark. Blue "ghost beams" will emerge in all directions and extend 64 blocks, which is conveniently identical to the maximum frame dimensions. So for max-sized Quarry, place one Landmark, activate the blue beams, place the other two exactly at the ends of the beams, return to the first Landmark, turn the blue beam off (remove Lever) and activate the read beam (right-click Landmark). Then place the machine against that Landmark from the outside of the rectangle. Note that it needs to face the Landmark directly, otherwise it will ignore your rectangle and default back to its 9x9 scheme.
 
4.2 Call it Bob if you like
If the quarry accepted your framing and is powered, it will form a yellow-and-black pre-frame, and a little robot cube will laser the actual (orange, non-mineable) frame onto it. The Quarry will also announce how many chunks it will keep loaded. Or none of this happens, and it will tell you that your frame is out of boundaries or too small. This sometimes occurs even when you did it right. Try breaking and re-placing the Landmarks, or maybe reduce the size by one block. Sometimes the pre-frame will not show although everything is correct. This is just a visual glitch.
Oh, and the Landmarks will drop when the quarry accepts them, so you can run and recover them now.
 
4.3 Maintenance Shaft
The quarry will proceed into an ever-deepening rectangular pit. Do yourself a favour and dig at least a 1x1 ladder shaft next to it, ideally starting directly under the frame. You will likely find yourself down in the hole at some point, and having a ladder to get back up is vastly preferable to the alternatives. Unless you can already fly.
 
 
5. Loot!
Don't power the quarry before you placed a chest on top or next to it. If powered sufficiently, the quarry will mine quickly and spout lots of blocks out of its top side. With the 9x9 default size, quarrying from sea level to bedrock will roughly fill one diamond chest. Most of which will of course be cobblestone, followed by dirt, sand and gravel. I recommend Reinforced Strongboxes for their portability, so you can easily swap them out if they are full. Later in game, you can hook your output to whatever automated sorting pipe and factory you are building.
 
5.1 Fillers Ahead
A great mass of rubbish, mostly cobblestone and dirt, will choke up your storage if not dealt with. An elegant way to handle it is compression. Use the Compressed Cobblestone (and -Dirt, -Sand, -Gravel) recipe from Extra Utilities to stow it all away. Pipe the stuff out of your buffer chest with itemducts and route it into Cyclic Assemblers, which will dump the compressed stuff into long-term storage. Note that there are two compression levels for sand and gravel, while there are four for dirt and eight (!) for cobblestone. Makes for interesting decoration, if nothing else.
Of course, you could just opt to void-pipe the mass items, or stack them in Deep Storage Units. Especially a Cobblestone DSU may be useful once you decide to visit the Deep Dark dimension.
 
 
6.Oil
This is annoying. Oil is quite abundant in Tekkit right now, and most quarry sites will hit one or more deposits at some point. The quarry cannot mine oil, and will ignore all blocks covered with it, which somewhat defeats the purpose here. There is no elegant solution that I know of, so this is what I do.
 
6.1 Suck It
First, stop the quarry when you see that it hit oil. This will usually require cutting the power - I usually place a lever on the energy cell to do that quickly. The quarry seems oblivious to redstone signals.
Then get yourself a Buildcraft Pump if you don't have one already (mostly iron needed). Also craft yourself a handful of Portable Tanks, ideally Reinforced ones. Grab those, along with a small energy cell, some conduits and fluiducts, and get down to the oil. The deposits are usually orb-shaped with a single topmost block. Dig that top oil block free, unless it already is visible, then place the pump directly above it. Wire it up and attach fluiducts with portable tanks to one side, then start pumping. The pump will extend its nozzle directly downward, remove the oil blocks and fill the tanks. Continue until the oil is gone, then remove your stuff, climb back up and power the quarry up again. Once you get a little practice, these little excursions are quite simple and quickly done. And they get you oil, which could be useful for power generation.
 
6.2 Stuff It
If you really don't want that and just need the oil to be gone, grab a stack or two of sand (or gravel) and simply fill the deposit in. The sand will displace the oil and leave only air when mined again. Be smart - let the quarry do the removing.
 
6.3 Kill It With Fire!
I never tried this, but supposedly placing lava above oil will make the oil respond like water. This means it turns into solids (cobblestone or obsidian) and can be mined by the quarry. Unfortunately, lava obstructs the quarry just like oil does (see 8), so you would need to place/remove the lava often for this to work. I don't see this working faster than pumping or sand-filling.
 
6.4 Invoke Higher Powers
I heard that at least one server community was so annoyed with the overabundance of oil that they had an admin remove it from chunk generation. It can still be generated with Oil Fabricators to fuel those rockets. Also, it might be enough to just disable Galacticraft oil, because that is what you will find underground. Regular old Buildcraft oil usually only forms in and around desert and ocean biomes, you can identify it by the surface geysers.
 
 
7. Water
The quarry mines fine through any amount of water, so it can basically stay. However, if an oil deposit is uncovered below a water source, it will mix in funny ways and make the methods from 6.1 and 6.2 very difficult. So I actually recommend removing water when it is uncovered, unless you know there is no oil, or don't care if all the blocks below any potential oil will remain unmined (note that this often affects the most worthwhile ones, like diamonds).
 
 
8. Lava
Lava stops the quarry from mining anything beneath it. This will often completely block off diamonds from your reach, so you want to solve this.
 
8.1 Water After All
It is recommended to flood your quarry. Yes, I said above that you should remove water, and I stand by that. But once the quarry is down between height level 20-30, it will be past any oil that might have been there, and nearing lava levels. That is the time when I recommend flooding your quarry with water. If there is a flow covering the mining level, any uncovered lava will turn into obsidian immediately, which can be mined fine by the quarry (you did sacrifice a diamond pickaxe when you built it, remember?). Works also for lava blocks in the side wall, so you can even drill through an entire lava lake. Note that this will put quite a lot of obsidian into your buffer chest, which might choose to overflow at this point.
 
9. Bonus Tip: Water Curtain
With all this, you should be ready to make a big, clean hole in the ground. But there is one more thing that might help. Flooding a pit of this size (9x9, and even more so if you go larger) is tedious both when placing and removing those water blocks. But due to the way water works in Minecraft, you can actually get away with placing just a single source block. Just place the water in one corner of the pit, right on top of the edge. Let it flow for a second or two, then put it back in your bucket and quickly place it one block further along the edge. Repeat for a few blocks until it has "wandered" for a bit. Then look into the pit. You will notice that you are creating a "curtain" of water that still encompasses all the area where your one block has been. Do this for one complete edge of the pit and leave the water block in place when reaching the end. That one block will keep the whole curtain up, until you remove it.
 

 
 
10. Enjoy!
Where to go from here? I recommend not going 64x64 in a hurry, as you will want some hands-on practice before you scale up. I like making 60x10 pits, so flooding is easy by just going along one of the long sides. After that, just do another 60x10 right next to the existing pit ("Stripe Quarrying", if you will). But at this point, you should be equipped to make your own decisions.
I hope this helps the newbies, and maybe even some more seasoned players. Read on >here if you are also interested about the additional pitfalls and windfalls when quarrying in the Nether.

Buildcraft Pump with Drums, or an army of slaves with buckets and Drums (slaves being other players who owe you favours for some reason).
Liquifacted Coal is a TE fluid that will allow you to power Compression Dynamos with just Coal as an energy source. I never did the math on efficiency, and I guess it only has merits if you are short on oil, while Coal is abundant. It should be more efficient than burning the same Coal in Steam Dynamos, otherwise the whole thing would be silly. Still, only worth your while as a self-serving project, or if you're short on Yellorium for some reason.

Actually I was mistaken. It's not Ctrl+R for reboot.
It's Ctrl+T for terminate or Ctrl+S for shutdown.

Break it with an pickaxe or steal his fuel.
You can also exit the game when in singleplayer and log on again. The turtle programming stops when the build in server stops.
 
Edit: Right click on it and press Ctrl+R for 2 seconds. It will reboot.
You can try a shorter tunnels like 'tunnel 64' or even shorter.

Lasers, eh?
 
Yeah, nope.
 

 

 
 
As for the materials... a quarry may be a good idea. Or two. Maybe three.
 
Sidenote: AE is easy and cheap... AE2 (1.7.10) is a horror with the chance of nightmares.

If you manage to get all necessary crafting materials into the ME network, then yes, you could opt to use the Crafting Terminal exclusively. But I imagine that you would need quite a few storage disks for that.
 
A note on the diamonds: If you are still short on them, you are barely in mid game, and it's actually quite early for an ME network. Most people try to get diamond (and Quartz!) production up before starting the expensive stuff. You could use Equivalent Exchange (easy), Mystcraft Ages (advanced) or simply set up an MFR Laser Drill (easy) to get more resources. Mining Turtles, Quarries and even RIM mining crawlers would work as alternatives.
 
You can place the Assembly Lasers just about anywhere around the Assembly Table, and it will profit from twenty or more of them.

Another tip concerning the assembly table: Like all Buildcraft machines, the laser(s) will keep sucking power out of your network even when idle, and they cannot be switched off via levers.
 
So you might want to consider putting an energy cell (any will do, but I would use at least a Hardened Energy Cell - the 80 RF/tick limit of the Leadstone Cell would make the laser even slower than it already is) between the laser and your main energy network, attach a lever to it and set its redstone control accordingly, so you can cut off power to the assembly table when it's not in use. You'll be wasting a lot of energy otherwise (of course, if you have something like a Big Reactor already running and producing excess energy, you probably won't care).
 
(FYI, switching off power can also be automated via Buildcraft pipes, logic gates and the "machine has work to do" condition, but that's probably too complicated to get into right now, so just go with the manual switch off method.)

AE construction gobbles up certus and nether quartz (and dusts), diamonds,, and gold like lemonade on a hot day.

But it's well worth it once built. AE crafting is an awesome thing too.

Plan on multiple, massive quarries to support this building.

Assembly tables cannot be powered directly. You need to build a laser and place it somewhere facing the assembly table, like this, for example:
 

 
You can place it above the table or sideways, however it fits best. Then connect power to the laser, put a piece of redstone on the table and the laser will start crafting your chipset. Make sure to put a chest next to the assembly table, otherwise the crafted items will simply pop out into the world. Apparently, the thing does not have an internal inventory for finished products.
 
You can use multiple lasers per table to speed up the crafting process.
 
 
Edit: AetherPirate beat me to it

You don't. Next you need to build lasers (need more diamonds, I'm afraid). Lasers are powered with RF. More lasers = faster crafting.

And put a chest above (next to?) your assembly table to collect your finished chipsets.

You need:
one ME Controller one ME Drive one Crafting Terminal one Storage Cell to put in the ME drive (4k for the start) for the simplest network.
 
Place all these blocks next to each other, put the storage cell in the ME drives first slot and connect the power from your power system to the ME Controller and you're done.
 
If you add more storage cells to your ME drive you can forget about 20 chests and keep all your stuff in one block.
Keep in mind to store thousands and millions of the same items (cobblestone, dirt etc) in Deep Storage Units.
 
You can put a Storage Bus to the side of the DSU (increase the priority on the bus) and connect it to your ME Network using ME Cable.
Now your dirt and cobblestone will be visible in the terminal when actually stored in the DSU.

For starters, I recommend an ME Chest instead of the ME Drive. As you will begin with a single storage cell anyway, this will be enough, and also allow you to access that cell directly, rather than through the Terminal. Makes for a friendlier learning curve, I think. The only difference between the Chest and the Drive is just that: The Chest allows interfacing with the cell, while the Drive does not, and the Chest holds just one cell while the Drive holds a bunch.
 
As for Access Terminals and Crafting Terminals, these do basically the same, but the Crafting Terminal is more useful because it actually allows you to craft directly with the networked resources.
 
Do note that storage cell efficiency drops with the variety of items stored. So you might want to diversify early, and especially get mass items into connected DSUs to keep the valuable space for important items.

Don't worry, those "sacred" rubber saplings you get from cutting down regular rubber trees are fake and won't actually grow into that gargantuan rubber tree. The real sacred rubber saplings are only found in jungle temple chests.
 
If you're interested in technical details, have a look at the item ID of the sapling and its meta data (the number after the colon), which should be displayed in the NEI tooltip. Regular rubber saplings are ID 698 without meta data (i.e. just 698), the real sacred saplings are those with a metadata of 1 (i.e. item ID 698:1), and the fake saplings have some other number as metadata. Can't remember which exactly, but as long as it's not 1, it's a fake sacred sapling and safe to plant, it will behave like a regular one.
 
(On the other hand, I remember reading in another forum that some dude actually took the time to harvest that massive rubber tree thing and ended up with something like 2-3 million pieces of rubber wood and raw rubber, and more than 100k saplings. So if you never want to farm wood and rubber again, go ahead, find that real sacred sapling in a temple, plant it and set a massive array of harvesters to cut it down. Expect it to take days. )

No idea, but I guess it's intended and meant to troll players. If it was a glitch, it would have probably been fixed by now.
 
 
 
That's what Deep Storage Units are for (2 billion items per unit). Or a massive AE network.

Even an array of maxed-out ME Drives won't take 2 billion of any item easily. This is the realm of the Deep Storage Unit entirely.
 
As for the Sacred Rubber Tree, I think this was inserted as a server-testing thing, and should be disabled by default. There is a configuration setting somewhere that will enable those saplings to grow. I'm not sure the regularly dropping ones are "fake", maybe just a further distinction to keep players from shooting themselves - or their server admins - in the foot. An MFR autofarm won't even collect them, let alone plant them.

Did you build your ME Network (AE mod)?

Craft yourself a Mystcraft Writing Desk if you haven't already, and some notebooks (3 leather in a V-shape). You can store the notebooks in the writing desk and organize your symbols in categories. And you'll probably need the writing desk anyway if you want to get into writing specific ages yourself instead of randomly generated ones (while you can assemble the pages you found to new age books in the book binder, the writing desk lets you copy them so you don't run out of those pages you use often).
 
You can read more about that here. This Mystcraft wiki is actually a good source of information because it's maintained by the mod author himself, so the information you find there is usually up to date.
 
Oh, and you may also want to have a look at this, this and this, too. Those are guides for understanding the Mystcraft grammar system and a few tips for writing ages exactly how you want them without any instability, randomness and other unwanted stuff.

When you enter the library the first thing you want to do is look up
Creepers trapped in cobwebs falling slowly...

Every Mystcraft age, whether generated randomly or to specifications, has page libraries scattered all over the world. They're rectangular stone structures, about one chunk in size and 15 blocks tall, not really common but not too rare either, and easily spotted on the map (use the large map by pressing X). These libraries have lecterns containing feature pages (randomly selected, not related to your current age's features), and there's a hidden chest among all the bookshelves with a rather large number of pages as well, or sometimes a notebook filled with even more pages. And before you ask, no, you cannot extract pages from randomly generated books.
 
Here's a pic of such a library:
 

Nobody's calling you an idiot, but I guess you did, in fact, not look hard enough .. I mean, actually reading all three pages of this very thread you posted in would be a good start, seeing as its creator CXXIVLDIVL had pretty much the same problems as you. Also, >Curunir's newbie tutorial answers most of those, and there's the wiki to help you out if you're looking for something specific.
 
If you absolutely need guides in video form (sigh), make sure they're for the current Tekkit version. Those you watched are outdated, things like electric furnaces and batboxes are from Industrialcraft2, which was kicked from Tekkit quite some time ago (it's still in Tekkit Classic, but that's not recommended unless you're feeling really nostalgic). Most machinery stuff is covered by the Thermal Expansion 3 and Minefactory Reloaded mods now. TE3 also handles basic energy generation via dynamos. So you can search for guides on those specific mods if you just want some tips on starting out and don't need or want the entire Tekkit experience laid out.
 
As a general rule, if whatever help resource you're looking at is older than mid-2013, it's probably for the wrong Tekkit version.

True. You can do with with MFR... once for every nether start. You can do it also with qCraft or AE multiple times. I was referring to the AE solution.
 
Edit:
 
 
Laser drill will give you every Ore you can find in the game for the cost of energy. Nether ores included.
 
Mystcraft Age - a defined by the player dimension with configurable weather, day/night cycle, colors, blocks, liquids, Ores etc. More here.
 
You can make a sea world filled with Resonant Ender......... or Fuel.
 
You pack a bunch of Symbols (in a strictly defined way with specified order) to a book and go for a journey (with a Linking book in the pocket). The dimension could be beautiful but it can be also deadly or poisonous (like burning in the sun deadly).
