Buildcraft

Buildcraft is a great mod for lazy miners.

You can make a quarry and mining wells and auto crafting tables.
There are pipes an they can transport any items.
?=Cobble, Stone, Gold, Iron, Wood, Obsidian, Diamond, G = Glass, -=Nothing
---
?G?

Each of these pipes have a purpose:
Cobble and stone have basic purposes but the cobble and stone won't connect! You must do cobble  + cobble or stone + stone or stone  + gold or something.
Wood pipes can suck items out of chests if the wood pipe is powered by a redstone generator (see below).
Obsidian pipes can suck up items off the ground and its range is increased if hooked up to a generator.
Gold pipes will speed up the items going through them if the pipe is powered by redstone. This will last 16 pipes but you can increase that by making the pipes after the speed boost be Stone Pipes.
Iron pipes are directional. You can change which direction the items are going in with a wrench.( see recipe below.) If you have the Technic Pack you can use a Philosopher's Stone.
Diamond pipes can sort out items. It will sort out using its inventory.
There are 3 types of generators: Redstone, Steam, and Combustion. Redstone just requires a redstone torch, steam requires redstone and fuel, and combustion needs fuel and water (to cool it down).
There are many types of gears, like Wood gear and Iron gear. All these are used only for crafting. You can craft a gear like this:
X = Sticks, Ingots, Cobble, Gold, or diamond. Y = The gear one level below the one you want to make. If you were making an iron gear, X would be Iron and Y would be stone. With wood there isn't anything in the middle.
-X-
XYX
-X-

The better the gear, the better the thing you can craft is.
For instance, Quarry is:

Mo' Creatures

Mo creatures is probably my favorite mod.
Don't want to watch the videos?

Mo' creatures pretty much adds more mobs, hostile and peaceful.
In the day there are horses and stuff. Horses come in many forms like Unicorns and pegasus. You must tame them with something like an apple or 2 mushroom stew. Then you can put a horse saddle on them.
Horse Saddle:
L = Leather, I = Iron Ingot
LLL
LIL
I-I
Or you can do:
S = Saddle
-S
-I
To breed 2 horses you must feed them each some pumpkins and get at least 5 blocks away. In about 5 or so minutes you will see a baby horse that will eventually become fully grown. To speed its growth up you can feed it sugar cubes. Crafting for sugar cubes:
S = Sugar
SS
SS
You have to tame the newly born horse, so have a apple or something ready. I recommend that you make a mushroom farm for mushroom stew.
You can also tame and breed dolphins of different colors like pink or blue. They each have temper levels so lower their temper first by mounting them first. Just right click it to mount, no saddle required.

Equivalent Exchange

Equivalent Exchange looks epic, trying to install it now.
If you don't want to watch the video, here's a summary but I don't remember everything.
This mod is about alchemy. Using 1 slimeball, 4 redstone, and 4 glowstone dust, you can make a Philosopher's stone. You may be thinking, "How on earth am I going to get a slimeball?!" Well, this is solved because you can craft a slimeball!
S = Seed, R = Sugar Cane (AKA Reed), s = Sapling
SRs
This crafts a slimeball in Equivalent Exchange.
To craft the philosopher's stone:
G = Glowstone Dust, R = Redstone Dust, S = Slimeball
GRG
RSR

Sorry if I messed up, the redstone and glowstone dust may be switched.
Well, with this philosopher's stone, you can make some awesome stuff.
P = Philosopher's Stone, C = Cobblestone
PCC
CCC
CCC
This will give you redstone ore!

G = Gold Ore
PGG
GG
This makes Diamond!
So, once you've made some diamond, and crafted some more you can make some dark matter.
P = Philosopher's Stone, M = Mobius Fuel, D = Diamond Block
DMD
MPM
DMD
With dark matter you can make some epic tools:
In all of the following:
D = Dark Matter, d = Diamond, - = Blank
-D-
-D-
-d-
Sword

DDD
-d-
-d-
Pick

-D
d-
Shears

You can make the axe, hoe and spade as usual but remember that you use diamond, not sticks.
Dark matter never wears out! Also you can charge with the 'g' key and it will have a special effect.






You don't really need that much cobble to get that diamond ore. You can always get some iron or gold ore and start from there. Dark matter kind of seems like a ripoff but if you don't have a mod like Zombe's then you can use too many items to get the dark matter armor instead of using Cheat Mod.
I wish the Philosopher's stone with 4 gold ore would give you diamond, not diamond ore.
Easy way to get diamonds! Kill a bunch of endermen and use the philosopher's stone to craft them into gold ingots and then to diamond.

The Interdiction torches will work with Mo' Creatures. Best use is with TMI.
