I'd sure rather buy toroids already wound. And I want to go down
to 50 Hz, so ferrite is out.

That one is around $70, in the noise on this project.



You didn't need to mention '100s of kHz then.

We measured it. That's what we found. I was impressed.

I would never have mentioned ferrite if I thought you were actually
using it at line frequencies.

You can't beat what they already have off the shelf then.

I thought you were making it do something other than what it was
designed for.

Well, we're driving one "secondary" winding and taking outputs from
the other three windings, and running up to a KHz or so, and closing a
wideband feedback loop around the transformer. Not on the data sheet.
Actually the data sheet kinds warns against this use. WDNNSDS [1]

PM alternators often drive switching shunt regulators, which can make
nasty waveforms. We want to simulate the alternator impedance and
tolerate whatever wild stuff regulators may do.


[1] we don't need no stinkin' data sheet

I don't think that either of them do electronics any more.

I wonder what they actually do.



For someone jumping on folks with lame mumblings about insults
and
topicicity, you sure do enough of the stupid shit yourself.

You entertain dipshits who spend decades making top posted
retarded Usenet posts about nothing, and then you ignore the very
ELECTRONICS related posts that he made many of in the last few
days
alone.

You are truly pathetic, and your butt buddy JohnTard DoeTard
must
really be one of YOUR sock puppets.


What do you do?



I was working on a device to assist in the detection and
destruction of Hamas tunnels.

It was on hold, but might get a new kick with all that is
happening.

So, you are like Donald J. Trump in that you lie (your comment
about Bill not discussing electronics, and then when caught either
ignore you ever did it, or toggle back to your same bullshit.

Post another pic of your shoddy personal soldering skills.

I thought you'd never ask!

Show us some of yours. Maybe Bill will grace us with some of his pics
too.



Mine are NASA quality, because the exempt equipment I work with is
still able to use 63/37.

I did a little NASA soldering, for a box on the S1B moon rocket first
stage. It was not something I'd want to make a career of. I do enjoy
soldering my breadboards, except for nasty packages like 0402s and
US8s and leadless stuff and things with power pads. And BGAs, which I
let my production people do for me.

Most of our soldering is now solder paste reflow under nitrogen, on
the p-p line. I try to keep thru-hole parts to a minimum.

Can't surface mount this:

(Amazing transformer)


Lead free tin whiskered solder is just another thing that dorks
like Trump remind me of.

ROHS solder takes all the joy out of a good solder joint. It's born
ugly.


This is the geekiest dick-size comparison contest ever, lol.

I'm going to show my girlfriend and her friends this thread and tell
them "this is what engineers do with their spare time."

Your use of the plural is incorrect. Nymbecile is not an engineer.

You butchered Marius with a chainsaw and fed him to the lions while the
parents and kiddies watched.

Yeah, and we butcher multimillion pigs and cows every year that has higher intelligence than a giraffe and see the remains in the grocery markeds. But, a giraffe looks cute

Dumb 'mericans think of breakfast pastries.

Yer lucky. Some of those 'old' nations didn't make it through those
last wars...

I don't get paid for doing electronics, but I do think about it from time to time.

John Doe doesn't seem to manage even that.

> I wonder what they actually do.

I'm active in the NSW branch of the IEEE - the IEEE has between 2200 and 3000 memebers in NSW (depending on the time of the year - student members are volatile). I've been editing their newsletter for years, and this year I'm treasurer again (mainly because the guy who had agreed to take on the job ran into a family issue, and couldn't do it). I do other things for them from time to time, but nothing all that significant.
