Looking at those awesome lamps at the beginning, it might not be a coincidence that Chicago was an epicenter of pinball machine manufacturing.

I think we're all glad they can make colonoscopy cameras so small. I mean, look at the size of video cameras in the 1950s!

There is something so satisfying about the damping on these old meters. Quick response with no overshoot.

Ah, 327s... and 328s, were the bane of my existence when I was in the Navy slinging wrenches at SH-60B Seahawks. The Audio Control Panel alone used over 100 of those and if the bird had a lightening strike or a transient voltage spike? I would be changing out 110-118 of those in one go. Never fun.

16:29 It's got Link printed on the side. Possibly from a Link trainer, an early flying trainer. It might have been made in 1979 but the design and technology seems a lot older to me.

The tech probably is a lot older, but a lot of military stuff is kind of if it works don't change it. The last place I did some electronics assembly for was a very small aerospace firm and all of the engineers were amazed by 3d prints coming from an ender 3 and had never heard of printing with tpu, it was a wild experience.

This is the same technique that was used in the early development of transistors in Japan. They projected the values across the room on the wall so they could control the temperature of the they were using to draw out the semi conductor.

awesome.

I used to work on some old SiPP/DIXI jig borers that used a television camera to read a glass scale etched in microns. Every week cutting oil would find a way inside and they required cleaning. This was way back in 1987 when I was a young tech and the machine was a decade older than me!

Amazed at the size of that tiny camera!

On that meter assembly, when applying voltage through variable resistance it usually makes more sense to measure the current. The typical bare panel mount meter that viewers would be familiar with are actually deflecting the needle in proportion to the current and if being used to measure voltage usually simply have a series resistor to pass current in proportion to the applied voltage.

@@motodude23. One of them has the metal case missing and what you see is black epoxy, white epoxy, and white RTV. It’s dirty and maybe corroded. They are very old and have been in a pile of junk. They weren’t burnt. Some CCD’s overheat when they fail but they don’t get so hot that they look burnt.

There is also a dry lubricant that is a black powder that is used inside the scope. The CCD is probably coated in that too. It gets all over everything.

Interesting meter and a fun to watch tear down / explanation. I think my parent's had a light meter for their camera made by Weston. I remember that name.

Those cameras are very cool. The whole video was, thanks to the person that sent the cameras. Few have ever seen cameras that tiny so up close.

So when I went to replace all my Soundcraft 2400 VU meters bulbs, I did it from the back by taking out the 8 channel assembly, well it turns out you can do the same thing and just pop the cover off to desolder the bulbs and replace, lol. Fun discovery for nerds.

I can't see myself very educated I went to grad school... before they banned the standardized testing.. play from an early age 2nd grade I was in 1/10 in most Sciences even English and vocabulary I was actually in the 1% of the whole country this is back in the 80s .. and I understand like a lot of technology and even cutting and Technology but I have no idea what you guys talking about? I do not understand anything that you guys are saying

I suspect there were better ways to display the information those meters were used for when they were created, I also suspect there was a dusty military technical data package that hadn't been updated in a decade or more that required that specific design to be used regardless of the current state of the art.

Ture design quality workmanship

Those little cameras... DON'T SNEEZE! 😉

I love the community that grew around this channel, like-minded people going out of their way to share amazing/obscure/cool tech stuff with Fran and we all get to benefit from/enjoy their passion/contributions, simply amazing

Very interesting. The name Weston is familiar to those who know about test equipment used on radios from around the late 20's to early 30's. Wonder if this is the same company?

Amazing technologies, both the cameras and the meter display. Thank you for showing us!

I was watching the segment about the tiny cameras when I got a call from a relative telling me that tomorrow they're going to use one of these on her. I mentioned that I was watching a video about how TINY and COOL they are and she was like "Oh, I thought they were the size of a pencil _eraser,_ not a pencil _lead._ This doesn't sound so bad after all." So you've done a public service. 👍

How much gold is in that.. 1 device. Really cool to see such an example of old tech.

My guess is this was part of an avionic inertial guidance calibration, while on the ground. The 50uA meter was a standard in test instruments, just magnified to allow fine measurements just a guess.

Oh my god. I looked at how much those micro cameras cost as It'd be really helpful for some of my projects and they are worth a fortune. If you can get a couple of them repaired and working that would be amazing.

Hi Fran!!! Fun today !! Yay!! !Enjoy!!!!1

I reckon those galvanometers represent the end of more than a century of design philosophy where measurement and display were still intimately connected. Digital panel meters still sort of do the same thing, I suppose, but I expect most later systems tend to separate data capture from display to lower cost and increase versatility.

Fran, I love your video and I love the content and I love you enthusiasm and your knowledge absolutely brilliant! and I don't mean this in a bad )Way) :) I meant all this stuff since I was very young I could have done anything with my life I can take Bose radios apart and put them back together I thank you very sexy for what you do! I don't know maybe I don't see many women that are is brilliant As You Are .❤️❤️❤️

Use lenses from a dvd burner to repair the cracked lenses

I have done some electronics assembly for military stuff and a lot of the parts are still insanely overbuilt like this using gold plated contacts, heavy duty fasteners, and incredibly wasteful cnc cut aluminum parts. It was cool getting to work with parts that were overbuilt instead of underbuilt like a lot of consumer electronics though.

"Mint In Box" is collector terminology.

It may have been mounted above your head

Butt Cameras lol

I see fun future videos with Fran hacking those tiny endoscopy cams..

Used in a simulator calibrator me thinks. Basically a reflection galvanmeter. I think you took one those before.

Love yer videos and historical knowledge.

That adjustment for the bulb rotation would null out the parallax in the optical system. Would it not?

Amazing tear-down of the military galvano-meter. Keep up the great work.

Awesome 😊👍🍀💞

Very interesting and enjoyable.

Does the bulb adjustment not move the bulb along its axis?

@FranLab

nope. Just rotates the filament.

Is the bulb adjustment screw really rotating the bulb, or is it moving it in and out?

Rotating. You rotate the filament to align it perpendicular to the film for the smallest single point light source.

So since we're looking upside-down that means we're looking upside-down?

Thanks Fran. That was a romp down memory lane.

Bullet Cam?

Why does my urologist use one bigger that a soda straw???

Is not that meter called a galvanometer?

I love how everything in this viewer mail episode was kind-of related. The lamps were also used in projection meters, and the cameras were microscopic like the lamps and the scale used in the projection meters. That's a cool coincidence! (Or was it?)

❤️‍🔥

Interesting. How it focused is quite novel. It's amazing how tiny a camera can be now. I wonder if it's the low end size limit?
