And thanks too for reaching out to curiousmarc and the whole gang. Bit by bit, module by module each and every equipment bay on the Apollo command module is being discovered and documented and brought back up.

Appreciate your services. Simply amazing stuff.

I wonder what they're going to do to make this machine CE compliant? I believe it is required to have a physical key for the source beam power.

Thanks again! Your willingness to help Marc and friends is greatly appreciated.

Amazing develop !! Cheers!

I have this general sense that it was harder back then... they were really having to think hard and figure everything out without much heritage to build on. And now... technology is just... well, normal. :)

It’s because the technology was way ahead of its time it was on the bleeding edge of what humanity could do a ct scanner isn’t every hospital in the country has one and x rays were all ready developed in the 1890s

Well we are in the sci fi future. Apollo was done with Bear Skins And Stone Knives.

The construction blows my mind too!

And a friend once said to me that Apple OS was the greatest achievement undertaken by man so far.....🤣🤣 I reeled off a few Apollo details and corrected him.

The connections inside the potted modules were probably welded, not soldered. I worked on the APQ99 / APQ116 terrain following radar system at Texas Instruments in Dallas back in 1968. All the connections inside the cordwood modules were welded, using stainless steel ribbons. They did that to prevent vibrational failures at the connection points. Very rugged after potting in a very dense potting compound, forming a nearly monolithic block. There were many tests done on the modules to ensure perfect operation before potting because after potting, the module was not repairable.

And in the AGC, individually hand-woven 0s and 1s in the core memory. Just mind blowing!

@@krnlg I have a 70's Seeburg Jukebox that uses Core memory also.

The basic idea is in some nice mathematics (log scaling and Fourier transforms - see tomographic reconstruction on Wikipedia) but the art is in the code.

Nah... just some sufficiently advanced technology, that's all.

I was taught the basics of it when I did my degree twenty years ago, so I assume it was already old-hat then. Not that I can remember any of it now, I think matrices were involved?

This is already done for tens of years.

@@KeritechElectronics But can still be confused for magic ;)

Thanks! We love these kinds of projects, so we have lots of fun working with people like Marc, Adam, and Ken.

02:30 I immediately spotted the Curta II cause I inherited one.

@@benjaminhanke79 Oh that's awesome. Cherish it it's a magnificent piece of technology with a very interesting story behind

You mean Curt Herzstark.

@@lumafield Imagine that a few years ago some of these Apollo parts were almost lost to history now they live forever.

Hmm you are right the title is ambiguous. Changed it a little.

Every video is fascinating! As a nation we became as one, cheering the successes of Apollo!

Reminds me of the wand on my old tube Geiger counter.

I was just thinking of capacitors

or just fuses...?

There seems no mesh pattern. Was it a metal mesh, by the way?

@@user-bh6ey1ke4n Yes, it was a very fine metal mesh.

moisture is not of great concern in a sealed box filled with nitrogen

Thank you! So glad you enjoyed them.

I never thought of that!!! I was leaning more towards them being geiger muller tubes

That was my guess too.

this was my thought, to absorb any off gassing from some components eg electrolytes that would leave corrosive residue.

Oh that’s very true! We measured the frequency before (it was pretty spot on), we can see if it changed anything. I suspect the does is too small to have much of an effect, but if it did something, we should be able to measure it.

Sorry if I gave this impression, but this is not an ad for Lumafield, or at least it was not meant to be. We have no affiliation with Lumafield. They did not pay us anything for this video, nor did they even ask us to make it in the first place. They did not ask us to say anything specific about them either. The story goes like this: they contacted Ken, as they are fans of his blog. They had seen his previous post where he used a much less capable 2D machine to reverse engineer one of the Motorola modules. They offered to put the Motorola module in their machine to help him out. Then Ken proposed we put my CTE in there, and then I thought about the gyro, and Mike thought about PSA module, and it went down from there. Hehehe. You wouldn’t want to miss that opportunity, would you? They were actually not aware of my channel, and I am the one who asked for permission to film (they accepted). We obviously were quite impressed and immensely grateful. They are equally appreciative that we can showcase what their new machine can do, of course. Enginerds helping enginerds, count me in any day…

They need to go after Apollo 10's "Snoopy". It's still in orbit round the Sun.

We have first dibs on it!

If you slice through the layers, it doesn't appear there are any wires (or anything) connecting to them.

@@EricMBlog yes i did notice that as I was just looking at the shape of it rather than what was inside.

@@rcb.p.c.2811 Yeah, I mean, it's not a bad guess. I posted my thought - either weights to tune the resonance of the case, or a spot where they used to be a component, and rather than revalidate the physical design when they deleted the components, they just filled the holders with a dummy. Of course it's perfectly possible that we just aren't seeing connections - but I've already spent way longer than I should look at these xrays :)

Thanks!

And while the NASA engineers worked their magic, you and your team leave me spellbound.

I was thinking: Modern magic exposes ancient magic. This has been a fun series.

would likely be problematic getting that data accurate through a metal casing

I think they have not opened them up yet. Give it a few hours for them to make them public.

Sorry about that! We’ve now made all of these scans public-you should be able to see them by clicking through.

Indeed! And the AE-35 prop is actually made from a real gyroscope, of which the real x-ray images are shown in the movie on a computer screen. Prescient. The prop is a dressed up direction indicator gyro from Sperry (Sperry G.M. Compass MK. 4B), similar to the Sperry unit we spin up in this gyro episode: kzfaq.info/get/bejne/puBdf6Roltqxh6s.html
