Talifax

Hello, my friends! Talifax here, wondering what mod the capsule stations in Hexxit comes from. I bought a Big Capsule Station for 32 emeralds, and now I have no idea how to use it!!! Not that 32 emeralds is a lot, but at the time I bought it it was! If someone could shoot me a link to the mod website that the Capsule Station comes from, it would be greatly appreciated. Thanks!
