This mod changes the normal way to produce circuits in a more complex and interesting one, using new liquids like lithium and adding a new powerful circuit called control unit (that will be used from "FactorioPlus: Machines" for craft, for example, the assembling machine mk11 ); it also splits the vanilla green/red/blue circuit in 3 different versions: from the easier to the harder. This mod is also compatible with Bob's ones if you want to play them together.
