Seriously.

Thank you so much.

Very nice video, indeed.

Those metal cans are probably filled with some sort of PCM (phase-change material). It's quite likely, that the PCM will be in a solid state at room temperature and what you found under the screw was not a seal, but the PCM itself.

Great video Mike! I miss having access to a thermal imagine camera at my old job. I may have to try to find one of these. But most are in the US and the export license paperwork to get one into Canada legally is a real pain! I remember reading of an old Cadillac car from ~2000 that had a thermal camera with a HUD for night driving. I wonder if the car is export restricted or is difficult to drive across borders!

Did you ever get the temperature measurement to read temperatures near room temp? I wonder if it would be practical to tap off the digital output before it goes to the DACs and come up with a way to capture the data directly for the highest quality video/images.

Oh, and your last image was full of Radicalness!

Brilliant, LOVE it!

I've saved a few search terms in my eBay app to wait for one of these coming up in auction again...

How do they prevent the calibration shutter from heating up due to infrared through the lens? I'm surprised there wasn't reflective tape on the front of the shutter.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

The incoming radiation is very minimal, it wouldn't heat the shutter significantly. That's why the Microbolometer has to be in a vacuum, to sense the minute temperature variations that the incoming radiation creates.

Its about time a Chinese company starts to sell a cheap thermal imager. I really want one but they are too expensive to justify the cost.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I seem to recall somewhere where someone built their own thermal imager (very low resolution) using a scanner or printer mechanism and a single sensor element.

Crude, slow, low res, but it worked.

Mike, I know why you have those 2 odd-ball connectors in your parts kit. 

You're in a time loop. 

You've been doing this fix for an eternity.

At some point in one of your past loops, you decided you needed those connectors, and you put them there yourself, so you could find them in this loop and exit.

Well that's my theory, and I'm sticking to it :)

PS: thanks for the teardown.. Since you finally exited the loop, we got too see it. 
Pretty cool video!

Ok if codeboy is right, mikeselectricstuff :
any chance to see a video review of breaking laws of causality ?
Would seriously be the best video ever, in this forum at least :)

Not difficult in principle if you lose the speed requirement - there are plenty of cheap thermopile sensors, and you could avoid the need for expensive optics using a pinhole type method, or reflective optics.
I also wonder if it would be possible to do something using an array of small SMD thermistors or diodes on a PCB

Excellent video Mike! Troubleshooting and repair at its finest. Can't wait to see how many ways you find to use the Flir for troubleshooting. There's another video in the making for ya, "1001 Ways to use Flir for troubleshooting".
