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

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

Less satisfying are the inverted scales...

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!

@ermyvids Ай бұрын

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.

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.

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!

@caw25sha Ай бұрын

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.

@cullenchase9161 24 күн бұрын

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.

@mikebarushok5361 Ай бұрын

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.

@RRosenberger Ай бұрын

@@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.

@RRosenberger Ай бұрын

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.

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. 👍

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.

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.

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.

@MrRlnansel Ай бұрын

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.

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.

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?)

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