Teckle is a tech mod that currently only adds tubes, a method of transporting items, if you ever used Redpower it's the same as that. To use the mod you need Substratum, or another mod that adds ores, and I strongly recommend using JEI for recipes, if you don't use JEI then please refer to old RedPower recipes to make your things!
This looks like a very useful mod! It is similar to Buildcraft, but this looks much simpler to use.
It will be interesting to see what the majority of players think about this mod.
By the way, first comment!
Teckle is now available for 1.12 this includes numerous bug fixes as well as the sorting machine, as usual downloads are on github.
