No, I wouldn't expect to see them in those things, but, off the top of
my head, in the last couple of months I have also repaired for friends:
- water pump (microcontroller)
- simple valve control system
- jigsaw (not variable speed so I guess I just missed with that one)
- battery chargers (op amps and microcontrollers)
- a couple of switching power supplies in things like DVD players
Someday I expect somebody will throw a battery-powered drill at me to
repair - maybe then.
The web site mentioned suggests that is so.
I've been repairing some
modern stuff lately for friends (ipod, cell phone, laptop, digital
cameras) so I'm not completely stuck in dealing with hardware from the
past, but recent uses of the 555 have escaped me.
They're just not much used in computers or "computery" things.
(like everything you mentioned above)
