m k, reply #3, the advantage is you don't need to. Pretty much any plausible apocalypse leaves the debrisof a collapsed society all over the place for the survivors to pick through. Copper wire will be available to be found in the wastelands that were once cities, you don't need to be smelting it from ore until your restarted society is large enough that you are starting to run out of pre-apocalypse cities to "mine" processed materials from. Copper lasts quite a while exposed to the elements before any serious corrosion sets in.

Even for "producing" the rust-prone steel alloys, you can still gather up rusted objects from the past civilisations, strip away the rusted outer surfaces and use the centre as fresh material for forging or milling in to necessary forms.

He talks about how he thinks electric motors are easier to make than internal combustion engines, but he's not thinking about the drive electronics needed to power the motors. 
It's all going to be steam engines, I think.

There's the saying that if a solar storm destroys all the transformers, she'll be able to rebuild them.

Time to go back to the brushes and commutator.

CatalinaWOW:
It is hard to think of any modern electronics that would be useful enough to skip working on staying alive for another day or week. 

Maybe GMRS radios if you had a way to keep batteries working.  Or a good welding system, though supplies would have to be scavenged.  How to make lightning rods.  And possibly LED lights for as long as they can be salvaged.  The latter assumes that you aren't too tired to stay awake after the sun goes down.  Subsistence farming is hard work and will be particularly hard the first few decades when enough mules and work horses have been raised and trained to meet every ones needs.

Older skills, gunsmithing, powder milling, blacksmithing, soap making, rope making, farriers, harness making, stonework, carpentry, animal husbandry, and a host of other skills will be of far more use than circuit analysis, C coding, or any of the other tools of the modern electronics trade.

If leftovers are available then my kit would have several geiger meters and hand dynamos.

Or was it clean apocalypse?
Maybe it was a bug.
