Artist's impression of ... something?
Jeroen Belleman
Artist impressions of electronics are often hilarious. Trace routings
are the instant giveaway; they make no sense.

I don't understand why people pay for absurd stock images when they
could use a real picture of one of their real boards. Probably because
they hire web designers who can't tell the difference.

Our new web site had that problem, full of absurd stock images. I made
them use pics of real boards and schematics.

https://highlandtechnology.com/

That first image is a digital delay generator board. Maybe we DO buy
FPGAs with glowing blue stars on top. I think someone took some
artistic license, but it's based on a real board.

Abstract images of PCBs are the popular-culture vision of technology.
Weird.

I had them add the arrow so people would realize to scroll down, where
to go next. But I didn't suggest that it should hop up and down like
that.

I general, the web has got very annoying lately. Popups, ads,
overlays, opening new windows, and more ads.

Youtube is worthless now.

I select X-axis tiling on this one and it cranks out very usable model

Yeah, I'll start getting concerned when it can be sensible with layouts.
But that'll be some other kind of software, this doesn't "know" anything
about electrical rules or any of that.

It stitches together fragments of other images until some other AI that
also doesn't know anything about the rules can't easily distinguish it
from a training image, whaddya want.

There is auto-place and auto-route PCB sofrware - most layout programs
do that - but both tend to be terrible.

Cool. These things are always artistically blurred, as if a bad
photographer had shot a real photo.

Even PCB shops use absurd stock photos of "their" boards.

I wish my boards had traces that glow.

Actually, some recently did. We bought a gigantic power supply and
experimented with how well a big polyfuse can protect various width
outer and inner traces.

You're right. It does look like the Kaaba:
<Loading Image...>
It works something like a compass, where Muslim worshipers face in the
direction of the Mecca. That's probably functional if there was only
one Kaaba, but global proliferation of similar attractors might result
in some confusion. I had a sample of that in early college (about
1965) when the national anthem was played over the public address
system every morning before the start of classes. We were expected to
face the flag, which was rather awkward if we were inside a building
with no flags in sight. I would usually end up facing a blank wall or
a urinal.

There's a little more behind image defects and artifacts in
advertising photography. I wrote something about it in RBT
(rec.bicycling.tech) where an obvious PhotoShoped image included
mistakes intended to extend the time that a reader inspects the image
trying to determine why the image looks wrong.

You can probably see traces glow in your FLIR camera. I don't own an
IR camera (yet) so I use liquid crystal sheets.
<https://www.edmundoptics.com/f/temperature-sensitive-liquid-crystal-sheets/11878/>

I also have a flat ZipLoc bag of ferrofluid:
<https://en.wikipedia.org/wiki/Ferrofluid>
For DC and low frequency AC, I just place the bag over the PCB.
Current flow is easily visible. Unfortunately, the frequency response
of the fluid is rather limited making it useless for all but the
slowest responding voltage regulators. However, that was exactly what
I needed for a switcher intended for an RF sensitive environment. Slow
down the switcher until the RFI/EMI disappears.

I don't currently have a project that could justify the purchase of an

would be interested in specs and a sample photos.

Hi Jeff! It's been some time we had news from you! Good to
see you're still kicking.

Let's call it Artificial Ignorance, or Artifical Stupidity.
It has some way to go yet before it will be truly convincing.

Not sure if that's good or bad.

Hi Jeff! It's been some time we had news from you! Good to
see you're still kicking.
Thanks. I'm alive and mostly well. Short summary. I disappeared
from SED just prior to the pandemic (early 2020) because I needed more
time for other things. SED was just one of several casualties. We
also had the CZU WildFire in Aug 2020. I gave up in Dec 2021 and
closed my office. Moving all the junk from the office to the house is
a continuing nightmare. Then came hiatal hernia surgery and cataract
eye surgery. Both took a rather long time to recover. I think I'm
done with all that and expect to be spending a little more time on
SED. Another reason I disappeared is that I haven't been keeping up
to date on what's new in electronics, RF, computers, etc. I thought
it best to read before I write, but couldn't resist adding a few
uninformed comments.

To avoid yet another endless AI discussion, I won't present my
opinion.

However, I can offer an interesting anecdote. I've continued burning
too much time on RBT (rec.bicycling.tech). Apparently by accident, I
received a Microsoft's CoPirate AI opinion on prospective innovations
in cycling equipment:
<https://rec.bicycles.tech.narkive.com/LM9ryTjp/the-ai-specified-bicycle-features-of-the-future>
I noticed that none of the AI suggestions are really innovative, new
or even clever. Also, they don't reflect any of the radical design
ideas I find in the bicycle design forums (which admittedly might be a
little too radical):
<https://bicycledesign.net>
<https://www.yankodesign.com/search/?q=bicycle#gsc.tab=1&gsc.q=bicycle>
That's to be expected because the AI was trained on data from existing
technology. When the AI is allowed to extrapolate trends and actually
attempt to innovate, the pundits call it "hallucinating". If I use AI
to brainstorm new approaches and ideas, all I'm going to get are
today's mundane, mediocre and probably patented technologies.

Let's hope that the light at the end of the tunnel isn't a fire.
