Think of it as just another tax break for the wealthy. :-)
True story: When the 9/11 Commission Report was published, our local
bookstore had some of the overstock (high on the shelves) positioned
right above the "fiction" sign. It's the bookstore right across from
the university, so I never knew if it was a prank, or if the employees

Put critical functions in firmware.
Do strange thigs with traces between board's multiple layers.
Use lots of potting compound.

I've used these printed Vivaldis before at 10 ghz.

You need .085 line to the diode, the Vivaldi is designed to use the
coax, minus some outer jacket, as its matching structure.

Hello,
I don't know the power of your uwave unit, but when it is a data link,
you will not have sufficient EIRP in the side lobes to detect with a
simple detector with low directivity antenna.
So best is to check the equipment's data first and do some math before
spending time and money.
Best regards,

Is there any anti-reverse engineering techniques out there? I was thinking
of making some not-so-obvious shorts between tracks though would easily be
fixable if you knew they weren't suppose to be there. Other ideas would be
to split the board up and have them fab'ed by different places but easily

115/230V voltage switch key for transformer?

Hello Folks,
Never needed this before but now I do: What are those things called that
you unplug and insert 180 degrees rotated to switch the primaries of a
transformer between 115V operation (parallel) and 230V operation
(series)? Circuit board mount.
Or better yet, does anyone know a source? Must be super cheap, as in

Norwegian "lyskaster", "lys" = "light", "kaste" = "throw"
Norw. "tennplugg", "tenn" = "ignite"
"Mutter" in Norwegian. There ought to be some
interesting etymology here.
Correct.
If you know both German and English, you should be able to
come a long way understanding written Norwegian and Danish,
and presumably also Swedish. The grammar is a simplified

You can criticise the practitioners to your heart's content. I'm
interested in the science, and it doesn't happen to be bullshit.
That you can't tell the difference between me and a full-time academic
gives a pretty accurate measure of your - nonexistent - perspicacity
in the area.
Dream on.
Your discipline? You clearly specialise in rural ignorance, but this
