You been saying it regularly for like 5 years and yet you still here all
the live-long day.

If everyone around you is an idiot and you still hang out with them
doesn\'t that make you King of the Idiots? Seems like a dubious honor!!!

That does seem to include John Larkin. He does tell us about stuff he has put together, but his design process looks rather like fiddling with existing circuits.

Getting interested in other people\'s designs does seem to be beyond him. He does seem to reject the idea of actually designing special purpose transformers.

My class-D amp PCB layout is done!

https://www.dropbox.com/s/97qrst7x1ir68ab/P902B4.jpg?raw=1

I\'ll get my guys to review it. Maybe we can order PCBs on Monday.

This board was wonderful. Everything just flowed. But I\'m glad it\'s
done. PCB layout and coding are boring and make me crabby after a few
days.

Ignore Sloman.

Yes, he is just a troll.

As much as I appreciate your *on topic posts*, if you think this is not
the forum for you, perhaps you should find another forum. I would much
prefer for you try to find a way to be less \"crabby\" rather than leave
the group. As PH indicated, use your kill file.

Who?

Seriously, I have only one person on my \"delete\" list (because he never
says anything that is both useful and relevant to electronics), and half
a dozen more on my \"mark already read\" list. The latter group sometimes
have useful and relevant things to say, but mostly not, so I only see
them when someone responds. I use kill-thread and kill-subthread freely,
and life is pretty sweet here.

The problem I have in posting electronics on this group is that I work for a company where what I do is mostly proprietary. That makes it difficult for me to post the interesting stuff I do. The second thing is that most of the questions I would ask are not general but specific and they are specific only after a bunch of background stuff has been assumed. So it is hard to ask for questions about things that I know that it takes many hours of pondering (after a required background) to get to the bottom of. So there is not too much I can do here relating to my day to day work.

That being said.....I have asked some general questions here and have had good responses that have been really helpful.

This group is un-moderated and pretty lively and has people who generally understand or seek to understand electronics......we are lucky to still have this. I hate moderated groups. Even among the trolls here ( fill in your favorite one) they still do have a background and interest in electronics.

I find the mix of electronics/politics to be OK.

Right, and when even working as a self-employed contractor even the
little-guys tend to want NDAs. It\'s not uncommon to work for a
little-guy who hope or believe they\'re working on something big big big,
and if you would like to be paid you at least have to give them the
benefit of the doubt.

Mr. Larkin seems to get a kick out of the idea that he\'s the only one
who designs \"real electronics\" for real money here, which is simply not
true. There seem to be a lot of retirees here with nothing better to do
who drive the bulk of political ranting but some of us at least have a
lot of years yet before we ever start collecting any social security.

If it\'s any consolation, I have seen enough of your critiques of
circuits that when designing circuits I kinda already know what they
would be already and can take that into account, and don\'t actually have
to ask explicitly.

Fisherman teaches man to fish, and all that.

That\'s no different than the constraints many of us operate under.
Everything I\'ve worked on in the past 40 years was under one explicit
NDA or another (prior to that, employers had their say).

And, as I can never tell which clients may be reading which posts,
I have always been very careful to use (bogus) sample applications
to put my questions in context. In that way, the actual application
is never disclosed.

For example, I may need to precisely synchronize the notions of \"current
time\" on multiple networked devices. But, whether that is to ensure
audio wavefronts generated by these discrete devices are \"precisely\"
synchronized *or* sensors/actuators on a factory floor are coordinated
in such a way that cause and effect can be observed (as if connected to
a single device with its singular reference time source) *or* pulsed
lasers synchronized with the actions of their individual targeting
mirrors *or* ...

The examples also serve to give a different way of looking at the same
problem. And, in many audiences, it\'s considerably easier for folks
to relate to something \"commonplace\" (e.g., synchronizing audio) than
something that would require an elaborate and detailed \"backgrounder\"
to bring them up to speed wrt the pertinent issues.

The second thing is that most of the
questions I would ask are not general but specific and they are specific
only after a bunch of background stuff has been assumed. So it is hard to
ask for questions about things that I know that it takes many hours of
pondering (after a required background) to get to the bottom of.

Exactly. Hence the value of the examples/analogies I described above.
They will be imprecise so posed solutions may not fit properly. But,
you may be able to gain some insights or alternative directions to
pursue that are more fruitful to your ACTUAL application/concerns.

So there
is not too much I can do here relating to my day to day work.

That being said.....I have asked some general questions here and have had
good responses that have been really helpful.

This group is un-moderated and pretty lively and has people who generally
understand or seek to understand electronics......we are lucky to still have
this. I hate moderated groups.

Moderation tends to attract control freaks. I subscribe to a number of
technical mailing lists. There is considerably less tolerance for OT
chatter, there. But, considerably more freedom in posting questions
without having to sate the curiosity of the folks participating in
those discussions (many folks who insist on knowing all sorts of
detail never really have anything to contribute -- so, why bother?)

Even among the trolls here ( fill in your
favorite one) they still do have a background and interest in electronics.

I find the mix of electronics/politics to be OK.

If the local theater is showing a flick in which you have no interest,
it\'s YOUR fault if you wander in and sit through a 90 minute show that
\"disappoints\". :>

While many, here, hide behind pseudonyms, *most* are at least polite
enough to avoid nymshifting. So, it\'s relatively easy to set up filters
to ignore posts from particular individuals.

[If \"OT\" was more universally used in subject lines, one could even
set up filters to elide all of that chatter!]

No, he wants to think that *he* defines what constitutes \"electronics\".
Largely from his apparent skillset deficiency in other fields.

I never said that. I personally know (and have drunk beer with) a few
guys who post here, who do very serious electronic design.

I do tend to design in public, because I can. I think that a lot of
other people could post their real circuits for discussion, without
violating any NDAs.
