Requires Bob's functions library mod.

This mod changes the way you build electronics, making the process more realistic.
First you have to assemble electronic components, then combine them into circuit boards.
Unlike in the base game, each tier of circuit board does NOT require the previous tier.
It also adds a 4th tier of electronics used for high end machinery.
Although it can work by itself, it is designed to function best with my entire set of mods installed.
