how to make some wire. […] finding some ferrous metal to turn into magnets.
These two ingredients put our 120v dynamo really far up the tech tree from “make fire.” Our intrepid time travelers are going to spend years trying to not be velocaraptor food and foraging for a meal themselves, all while making stupendous amounts of charcoal and prospecting for ore.
Oh don’t get me wrong, our intrepid adventurers are going to have to spend a good chunk of time on this with no guarantee they live long enough.
However assuming knowledge isn’t a gap (given they already built a time machine), iron ore is fairly abundant in many areas of the world, and it’s relatively straightforward to build a kiln that would reach the appropriate temperatures to smelt the iron into bloom (that can be hammered into workable iron)
It’ll take many, many years, but assuming they can avoid ending up as food, it doesn’t seem impossible
