Another idea worth considering... See if you can arrange your job to get
you closer to the hardware.

There are lots of hardware guys who don't know or like software. They need
somebody to write code when they are checking out their new widget. If you
are working with one of them when they locate a bug, they will probably
take time out to explain what is going wrong. Frequently that leads to
understanding how it was supposed to work and/or how some other part that
works right works does its thing.

If you are interested in books, I suggest Horrowitz and Hill, The Art of
Electronics. There is something in there for everybody. I think there is a
lab workbook and/or problem set, but I don't have a copy. It does a real
good job of covering the practical aspects of electronics, the real world
as compared to theory.
