I think some would object to the egg.

Q: what is a \"packet\" of vanilla? I want to make some
biscotti al latte and each Rx refers to vanilla in that
quantity (here, we would measure volumetrically)

I\'ve been thinking for some time now that EE schools don\'t turn out
people who like electricity, but maker culture might.



\"And to make it your life, there has to be a lot of high-status,
high-wage, high-interest jobs to do at the end.\"

Software-startup culture is glamorous in its way, the young kids
can very quickly feel like they\'re working on something novel.

Coding is an easily acquited skill. It requires no math, no
science, little discipline, and is a tightly bound, artificial
abstraction layer with little visibility up or down.

Electronic design and especially analog design distresses most
people. They are intimidated by the endless possibilities.

And most people are afraid of electricity. I got an emergency call
yesterday to help a giant rugged construction guy take some
pendant lamps down from a hair salon. He\'s terrified of getting
shocked. I\'ve had EE interns who won\'t touch a PC board that is
known to be running off 3.3 volts.



The EE jobs available tend to be at established companies, like
Northrop Grumman or Nexteer Automotive or Fisher Scientific or
BAE systems etc, you can go down the list on job sites and see
what they are.

The big aerospace companies used to design board-level electronics
but aren\'t replacing the old-timers who could. They outsource more
now, fine with me.


Biggest complaints you hear from EEs about working places like
that is that the jobs aren\'t particularly high status. They don\'t
pay particularly great. The \"company culture\" sucks. And worst of
all the job responsibilities tend to be rigid and the work not
particularly interesting.




Some people care about status, and some people just enjoy being
left alone to make things that work.

Of course, a really good EE manufacturers his own status, if
he/she cares.

I was \'called in\' by the landlord of my business unit, to replace a
bathroom light bulb. . . . . for a CNC machine \'programmer\'. Advised
him not to mention this to anybody at work. Used to be a joke about
this. Not so funny any more.


Also called into another business to \'break in\' a new production line
tester/troubleshooter. He didn\'t know what the color code was. I
guess he knows it now. Local tech school graduate of recent import.

I\'ve known onshore theoretical physicists who had to be shown how to
hammer a nail into a 2x4 without bending it. So it\'s not super recent.

And of course status-conscious places are miserable to work in. Give me
an outfit where folks just want to get the job done, any old time.

Mhm, right now I\'m using the module\'s circuit (plus that blog that tore
it apart) as that jumping off point.

At the moment, I know it\'s a 555 running in astable mode, with the
\"sensor\" part being a pair of traces on the PCB acting as a capacitor.
Best I can figure at the moment (and not having understood that blog I\'m
reading... or the full implications of the 555 datasheet), those
\"capacitor-of-pcb-traces\" will potentially vary the 555\'s duty cycle,
which means the cap on the output will have more time to bleed through
its resistor... Or maybe once I get the understanding, I\'ll see that the
\"sensor\" part is actually on the output, rather than the input...

For example, *hair* stretches when wet. Can you conceive of a way to
sense this elasticity?

There are whole bunch of positions sensors you buy. Linear variable diffential transformer (LVDT)are pretty reliable way of sensing absolute position.

Could probably do something with a load cell ... soak the hair, stretch
it in the cell (but cell still reads zero), as it dries, the cell will
deflect.

Load cells frequently rely on stain gauges. They can be pretty good, but the LVDT is easier to understand.

Water is sensed in fuels by noting changes in conductivity.
Yeah, I have the feeling a resistive sensor would corrode in no time
flat...

So use a stacked pair of non-progressively wound toriods as your sensor. You drive one and the only coupling to the second toroid is the current circulating in the fluid that threads both of them. No exposed surfaces to corrode.

It\'s a bit bulky and you have to completely immerse both of them so that you have a well-defined and stable current path through the fluid, but it is a neat solution when you can use it.

makes a bunch of divide-by-0 or divide-by-almost-0 points, which sort

Not exactly; as any least-squares fit formula shows, a set of data points
does NOT have to be equally weighted data points; the
divide-by-almost-zero points might be all insignificant in the statistical
weight sense, during that \'reverse FFT\'. You have to, after division,
reconsider the FFT step; the \'d(omega)\' part of the inversion integral
should be replaced by the reciprocal of the square of the expected precision
(which is low for the result of division by zero), and results renormalized
accordingly (instead of just FFT on a list, it has to be a weighted integral,
with weights that either are forced to sum to (1) or similarly normalized).

I do it in time domain.

If there\'s a division by zero in the f-domain, why isn\'t there one in the t-domain?

For starters, there are no divides.

Yes, but the only \"value\" is about 2 hours of \"read from this stack of
DVDs\". Which, is more of a case of \"well this is annoying\" and less of
\"well, I am screwed\".

They don\'t know that. So, they just blanket target everyone (that
they can)... and hope they catch a few (fools).

You might, instead, look at imaging the disk onto more spinning rust.

I do that as well; but less frequently. My underlying point was more
that the \"valuable\" stuff has (completely offline) backups.

Ours seems to not have been tested well in suburbian
settings. Yet that is where people with disposable income live. Plus
they voluntarily gave up VHF frequencies which was a big mistake. I told
a station manager here that all this would result in diminished ad
volume and later \"personnel adjustments\" (code for layoffs). He didn\'t
believe me. Then it happened.

VHF? more like UHF! 474 to 626 MHz or so:
https://radio-tv-nederland.nl/dvbt/digitenne-kpntv.html

If I ever want to watch something interesting it is on the Internet or a
DVD from the library. However, now that I re-started ham radio I haven\'t
seen any movie in months. No time.

I just check these in the morning:

https://www.tvguide.co.uk/?catcolor=&systemid=79&gridspan=09:00
If anything seems interesting then I program a timer (good movies for example)
Box records to a 64 GB USB stick in HD....


I\'ve been in Europe a few years ago and the relative I stayed with has
satellite TV. A bazillion channels. What I saw there only elicited the
same reaction as the 200 channels in hotels here, a big yawn.

Well you gotta find the gold in the dirt...
Some things I really like, like the repair shop on BBC1,
afternoon at around 4 PM UTC .. fixing old things, maybe because I had a repair shop.
Those guys are good and I still learn from it.
There is so much more to broaden your view, much better than \'the weather is cloudy here\' ...

Analog? You mean wallwart noise on RF shortwave? brrrrrrrrr
I do have a HF transceiver, and a Baofeng of course....
Maybe when WW3 is in progress to say bye bye world?
Or listen where there is still life?


Yup, analog. Although CW is technically a \"digital mode\". That\'s >95% of
what I am doing, using squeeze paddles and the computer between my ears.

Well my Morse sucks, SOS I know, you can use software to code and decode from text these days I think.

Sat goes to UHD (Utra High Resolution, 4 k) there are already some test transmissions..
My TV cannot do that, and at my age at the normal viewing distance I doubt I would see much difference,
You would need a BIG screen, no space for that.
HD at 1920x1080 is already amazing, see every hair on someone\'s face,,,
Also at UHD the recordings get much longer .. need more disk space.
So a movie becomes like 128 GB..
The cheap sat boxes I use simply record to a 128 GB or 64 GB USB stick.
Those use some old windows format, so every few GB it starts a new entry...
I can read those files on the PC or laptop and \'cat\' those together on a real Linux filesystem
to get one big file.
I have mostly stopped storing things now on optical, Bluray... All SDcards now...
The box was full with 1000 disks,
