Add's Lua based computers to the game
This mod is a utility for Mo' Creatures. It allows you to set where the creatures spawn.
EnderStorage is a mod that offers a means to store your items in The END, causing them to be everywhere and nowhere at the same time. All EnderStorage makes use of the magic of colors to link storage with its little piece of The END. Any EnderStorage with the same color code share inventory (even across dimensions). Currently there are two types of storage, EnderChest and EnderPouch.
The Equivalent Exchange mod is based around alchemy. It adds a number of extremely powerful end-game items that require large quantities of diamond to make, and large quantities of glowstone to power. It also grants the ability to easily condense materials into more valuable forms, up to diamonds and even beyond. Most of its recipes are based around the Philosopher's Stone, which you will need in order to access much of the new content.
Adds several new blocks to IC2 to make your systems more effecient.
Combines large amounts of solar panels into single blocks turning your solar arrays into effecient small scale power houses.
Nuclear Control addon allows you to build efficient monitoring and notification system for your nuclear reactor. Also you can use Howler Alarm and Industrial Alarm in any case when you want industrial-style notification/alarming system.

This is it. IC2, the future of IC. While playing it, you will feel right at home again, rediscovering most of the stuff known from IC. However, once you get your machines running, you will quickly notice how smooth and well-designed everything works now. Wiring is easier, batterys aren't as twosided (on/off) anymore, new cables, rubber stuff, new machines, EVERYTHING was added. Create obstacle courses of Metal Poles and Rubber-Sheets, explore the Nether with an Electrical Jetpack or blow up whole landscapes at once by using the Dynamite-O-Mote. Or discover the much more complex mechanisms of Nuclear Engineering, blow up your hut or burn your hands. Or grab the rusty ol Composite Vest, and start hunting Creepers with the new, allmighty NanoSaber.
Tweaks your inventory handling to be more intuitive. Break your iron sword in the heat of battle and don't have time to replace it? No worries, if you have another one handy in your inventory it will automatically be moved into the last slot it was used! Works with all stacked items!
IronChests adds several new chests to the game. One for each type of metal. You can even upgrade them!

Lumy Skin Patch repairs skins for Minecraft because Mojang no longer supports skins for No-UUID Minecraft versions. Lumy Skin Patch uses the current Mojang API to load the skin texture.
MAtmos is a sound atmosphere generator. When you play on any server or in singleplayer, it looks at your surroundings and generates natural noises as a soundscape, such as birds in the forest or rumbling near a lava lake or wind gusts on a hilltop, which fills out the perpetual silence of Minecraft.
Mo' Creatures adds over 40 new mobs to your game, it provides many new animal and monster mobs, as well as the ability to tame and ride some.
Create and manipulate force fields to your will!
This is a fairly basic mod. It makes the eight 'ores' - coal, diamond, gold, iron, lapis, redstone, sopper and tin - spawn in the nether so that you have a reason to go there.
Have you ever wished minecarts and rails had received a bit more attention during development? Well that ends now! Gone are all those broken bits and in their place are a ton of new tools to build your massive rail system. If you ever cared about rails, you wont ever look back!

A collection of configs for all Technic mods
Thaumcraft is one of the largest magic modification for Minecraft. It has a very steampunk-ish feel, featuring utilities and tools rather than grand demonstrations of unearthly power (although it does feature a couple of those).

Thermal Expansion, at its core, is a 'tech' mod - it's a mod of what ifs. For example, what if you could turn water into ice or snow with a machine? Or how about a machine that could combine lava and water however you choose? What if there were a wool that didn't burn? Or, what if you could set up advanced yet extremely compact production chains that didn't require redstone engines or complex pipe routing? If any of that interests you, then you may want to check this out.
Chop down a tree with a single mighty blow!
This is a small mod that adds two new blocks that I thought were missing, related to BuildCraft and RedPower. It's called TubeStuff because I don't have a better name - feel free to suggest one. The buffer could also use a less generic name.
In its simplest this is a mod that allows you to transmit your redstone state wirelessly. Even if you dont use redstone this mod could still be for you. Found an awesome landscape you'd like to mark, a cool cave to explore, or keep losing your way from base to base? Ever wished that compass pointed somewhere else or there was a way to mark things on a map. Well now there is. With the wireless addons component of this mod you can use wireless signals for navigation.
