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.

** 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.

Hard to believe, but Fran is not a girl.

Hello,

here is some more information:

So that thing navigated to the moon and back.

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.

Back-scatter X-rays???
How does that work - especially to get focused images???

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

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.

She is awfully cute....

She's a he.

Well, the image, of whatever it is, is cute. Disney characters can be
cute, and they don't even exist.

Pity, though. We need more geek girls.

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.

Pity, though. We need more geek girls.

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.

Nope. Notice that she has no Adams Apple or residual facial hair in
her photos.

I worked on two modules that were used in the S1B booster stage, when I
was still a freshman at Tulane.

The tememetry system had a scanning ADC that sampled each input at
something like 4 or 6 samples/second. There were some events that needed
to be timed to milliseconds. One box that I worked on (I designed the
test set, not the box itself) was the Time Correlation Unit. It receives
a trigger and generates a precise linear ramp, which drove a telemetry
ADC channel. The samples had enough information to interpolate the event
time.

I still use the technique:

http://www.highlandtechnology.com/DSS/V660DS.shtml

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.

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.

Well, (s)he's had a real good job done, then. (S)he even SOUNDS
like a woman! Had a voice box job done, I guess.

There's also Larry (Lynn) Conway, who was instrumental in the
early days of VHDL synthesis with Carver Mead. Lynn looked a LOT
better as a woman, too.

I guess we'll just have to settle for Tatiana van Vark, then,
for geeky women. She's got to be the only person in the
world who has the entire electronics suite of a Vulcan bomber in
her living room!

My favorite, though, is the video of her playing with her
inertial stable platform.

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.

http://en.wikipedia.org/wiki/Ashawna_Hailey

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.

 

[Tom Del Rosso]

Well, I watched the whole thing. Right at the beginning, and in a few
places, she momentarily displayed what might have been an adams apple.

I guess you didn't see this.
