    Applied Energistics 2

    A Minecraft Mod about Matter and Energy

    Applied Energistics 2 (AE2) is a comprehensive mod for Minecraft that introduces a unique approach to in-game inventory management.

This allows for compact storage solutions and easy access to your items. Another significant feature of AE2 is its automatic crafting capabilities. Players can set up patterns and recipes which the system can automatically craft on demand. This greatly streamlines bulk and complex crafting processes, saving time and effort. AE2 adds a whole new level of strategy to your Minecraft builds with its networking and channel system.

    BuildCraft

    BuildCraft

    BuildCraft mod for Minecraft

    BuildCraft is a mod for Minecraft. BuildCraft itself is licensed under the MMPLv1 or MPLv2 if you need the specifics, but generally, you can. By default, many simple (primarily worldgen/decorative) blocks are supported out of the box, such as the kind of blocks added by Chisel 2 or Ztones. However, for many other mods, special support is required to allow for rotation and remove the chance of duplication bugs appearing. BuildCraft Compat is a BuildCraft addon designed to add cross-mod compatibility with other mods. BuildCraft is in the process of moving back to the MJ power system. However, due to BuildCraft being in alpha no other mods support it (or should support it, as its still making breaking changes to the API.

    Charlotte's Utilities

    Charlotte's Utilities mod for Minecraft Forge made by Sharshar

    Charlotte's Utilities is my first adventure into modding Minecraft. I wanted to have some extra utilities and things for my server that I couldn't find in other mods, or if I could I was able to think of a different way that I would prefer to implement them. At its core, this mod pack is just a collection of utilities that I feel improve the game experience. Everything is fully configurable in the config file so you can change, enable, or disable whatever you feel is best for you! The mod has quickly developed into one that's aimed primarily at the builders of the Minecraft community, and I plan to expand on that idea going into the future. My goal is to provide new, unique, and easy ways to allow players to construct whatever comes to their mind. I take feedback very seriously and if you have a good idea I won't hesitate to implement it. Development of Charlotte's Utilities is made possible by Full Effect Hosting
