    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.

    You can select XY tiling with this software and tile them out to cover a

    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

    It stitches together fragments of other images until some other AI that

    There is auto-place and auto-route PCB sofrware - most layout programs

    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.

    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.

    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.

    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.

    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.

    looks like the pilgrimage to Mecca.

    You're right. It does look like the Kaaba: <https://cdn.britannica.com/43/156343-050-CD194769/pilgrims-Muslim-Kabah-Great-Mosque-of-Mecca.jpg>
    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.

    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.

    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. <https://rec.bicycles.tech.narkive.com/sGdviHeE/bicycle-infrastucture#post8> <https://rec.bicycles.tech.narkive.com/sGdviHeE/bicycle-infrastucture#post20>

    I wish my boards had traces that glow.

    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.

    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.

    We recently bought a few nice thermal imagers with clip-on close-up
    lenses, about $700 total. I could post the details next week, if
    anyone is interested.

    I don't currently have a project that could justify the purchase of an
    IR camera. However, I am curious. If it's convenient for you, I
    would be interested in specs and a sample photos.
