Ok, So from the top. This is why i didn't put them in the first place. Greg wouldn't have the skills necessary to survive for long on his own without others. He could scavenge as that's not exactly difficult, and being in a crumbling base, you more than likely had to get creative in finding goods. Trapping was more to attuned to creating traps/distractions rather than capturing things like conventional trapping. So those Electronic devices would be the reasoning behind it.

As for not having any in the inventory. He doesn't have any. I was going to give him one but switched it for the water. So one of his first little priorities is to find some electronics and build some more, as well as try to find people to survive with that won't kill him. Impromptu electronics is yeah, jury rigging. In normal circumstances Greg could operate them with a mastery. Without half his tools or services, he has had to learn while in the camp how to get the same results using a more 'brute force' method. crude mechanics is a similar thing, just applied to mechanical objects. He can do rather crude work on engines and others mechanical objects to get them operational.
