  1. For anyone who hasn't seen this yet, it's a Saturn V guidance CPU board.



    She x-rayed and reverse-engineered it.

    Well I like Fran more than that annoying EEVBLOG Aussie.

    But don't you think that is some sort of clever prototyping system
    rather than a final product? I mean would the final product have
    unpopulated locations?

    I believe her when she says it is a real part, it reminds me of the slightly later IBM multilayer boards with ten pin micro-module hybrids. Plenty of those had gaps and unfilled spaces too. I once peeled the top off a micro-module, a thick-film hybrid with flip-chip transistors. Seem to recall just one bypass capacitor on the whole board. I think they were used extensivelyin the 360 series of computers right thru to hi-end memory selectronix typewriters until the 1970s.
     
  4. Neat, (Dang, I love geeky women.. I wish there were more, but don't tell my wife.)

    ** While watching the vid, I was looking around the workshop for clues as to
    what her actual line of work might be.

    The I spotted a small, AC supply transformer with a shiny copper band around
    it on the top shelf - such trannys are typically found in audio gear,
    like guitar amplifiers. Copper bands suppress the external magnetic field so
    hum does not invade sensitive parts of the circuitry.

    Fran has a number of vids on U-Tube and it did not take long to find one
    that revealed her occupation - she hand builds "boutique" guitar effects
    pedals under the brand name of "Frantone".

    Or at least she did. Seems after almost 20 year of that, Fran has moved on
    to another business activity recently.

    More info that you will ever need is here:

    BTW:

    Hard to believe, but Fran is not a girl.

    Hello,

    no, it did not. The Saturn V lifted the Command Module, the Service
    Module and the Lunar Module into an earth orbit and the last stage of
    the Saturn V made the injection to the moon. But only the Command Module
    and the Service Module made the trip to the moon and back.
    The navigation to the moon and back was mostly done by the Apollo
    Guidance Computer within the Command Module.

  8. It's a hand held X-ray gun. He's using differnet 'Mouth pieces' to
    capture the image. ( the black thing on the table)

    I was going to mention the fact she is holding the board while he is
    x-raying it. but it's not many expoures.

    Cheers

    Back-scatter X-rays???
    How does that work - especially to get focused images???
     
  10. Going into the corset business now. if s/he's a typical trans, we sure
    could use more of them.

    In the former Boston computer museum, besides the actual Apollo
    guidance computer, there was also a mockup, in which the visitor could
    try to operate the computer. I tried in the 1980's some sequences
    and it looked like using a preprogrammed TI-58 calculator (enter
    values into certain registers and hit RUN (R/S)).

    But in reality, the Apollo flight was handled by ground based
    computers. The distance to the CSM/LEM was known by two way ranging
    (coherent transponder in the spacecraft) with an accuracy in the order
    of wavelength.

    To get the real XYZ coordinates at least a third receiving station is
    needed (three way ranging) or some solutions can be discarded, as the
    orbits would be impossible due to orbital mechanics.

    Eh, she could lose the glasses and get a part on Big Bang Theory. I
    doubt she would get a double look as being anything other than a woman.
    I've seen some transgenders where well, there is no question. More power
    too her.

    As it stands, the video was interesting. I had no idea anyone did
    surface mount back then, but looking at the board, I'm not sure what
    surface mount accomplished. The pitch doesn't look any tighter than
    DIPs. The lead inductance is probably higher than a dip since the leads
    fold around the package. That is, they gave the part some "spring",
    probably not to crack the ceramic.

    In a lot of ways,IBM never got the credit it deserved for technological
    breakthroughs, or even their tech business other than "business
    machines." They either invented the hard drive or perfected it
    (depending on your source). [They are probably still cleaning up the
    ground water at the old San Jose plant.] IBM had some sort of satellite
    business, though it got sold off.

    As it stands now, I haven't a clue how they make money today (services
    doesn't tell me much), but they managed to reinvent themselves.

    Too many years ago I found myself in Huntsville pitching a product, and
    had a chance to look at the rocket museum. They have/had an Apollo capsule.

    But getting back to the wiki on the LVDC, it probably didn't matter than
    the computer was slow. (2MHz and bit serial). I was at a MEMS lab where
    they were doing sensors for missiles. The line they used was "It is hard
    to shake a rocket." The bandwidth was only a few hundred Hz.

    Well, heshe's being careful to maintain just the right angle with the camera. Looks like a bald guy wearing a ridiculous Barbie-doll wig to me. They undergo some kind of operation on their vocal chords to change the pitch of their voice, but that, like everything else they have done, doesn't work.
    You can keep them. As for the trans, I don't really care about hisher personal situation as much as the technical content of her vids, unimpressive asit is, she could be a three-eyed green Martian for all I care.

    That sounds rather similar to to what Tek did for the 7854 sampling /
    real time scope. You could use it a a real time scope but thanks to some
    rather unusual techniques it could also do lots of interesting things
    with pseudo-random sampling of repetitive waveforms. It also did the
    ramp and a dual sample. The ramp told the scope where to place the
    sample in the display line and then it could do rather a lot of fancy (at
    the time) math with it.

    ?-)
     
  18. That's a serious sewing machine she's got. I'd like one of those
    industrial Jukis.

    They actually have an oil pan under the base so all the parts are
    bathed in oil during operation. Really popular in the schmatta trade.

    I had met Shawn Haley back in the day when he was a guy. It was strictly
    a business meeting since we were doing a Hspice eval. Nice guy. Very
    bright. It was pretty obvious he did IC design back in the day and
    wasn't a code monkey. [Lots of people were peddling improved spice at
    the time.]

    I never met the other brother, or they punked me since they are twins.

    It was pretty much a shock when I read about his conversion after his death.
    I really hope she didn't wait until her business days were over before
    doing the change, with the idea that nobody would buy software from a
    transgender. All I cared is if it worked, could we justify it, and would
    they support the product. Hspice won on all three.
     
  20. I guess you didn't see this.
