Because I say so. Prove me wrong.

Jim, I'm not getting into this stupid ****ing match. But, erm, shouldn't you
be working on your mid-January project, rather than trading verbal volleys
with John? And, uh, what about your offer of free consulting, which I took
you up on a month ago? I had hoped to get at least a "little" bit more than
I paid for. The design is basically done, and I'm in the process of testing
some of the subcircuits and getting bobbins and ferrite cores for the
transformers. And I realize that my project is much more than a few hours
work. But what I WOULD like is at least a simple critique of my design for
the high-isolation DC-DC converter, and perhaps your official blessing (or
not) based on your PE credentials. I want to have some assurance that there
will be no design-related problems in the future from the 480V 200A mains
power jumping into the control circuitry and creating a big mess.

And if your advice and critique are sufficiently professional and valuable,
I may be interested in additional consulting work for which I would pay a
reasonable amount. Can you at least generate a report based on the material
I provided?

Please?
