Cold environment testing? Isn't it like -40°C to -80°C at cruising altitude anyways?
Yes, and we have machines to do these things. Ours could easily fit 4 flight computers for a 4, 8, 12 or 24 hour test at -70C to something crazy like 50C
... so your machine could probably cool my GPU nicely is what you are saying ...
Yes. And it could change the temperature very quickly too. Unfortunately I can't remember how fast.
Ohh, rapid tem changes testing too, nice, probably with some active heat transfer system (... I mean a fan).
Specialised machines/tools/machine-tools are great to nerd out for a bit.
Like I said, I didn't appreciate how cool it was at the time. I was also paid a third of what I make now, that might have something to do with it.
Oh, I recognise that feeling of not being able to enjoy or be proud of work that you dont dislike, just because you know how unfairly you are compensated.
when I was a kid, my dad worked at Lockheed... they had the coolest Take your Kid to Work Day. The basement was where the fun was- specifically the prototype testing lab with the 50 pound hammer that they were constantly knocking around mock ups of computer cabinets, the ginormous vibration table, and, yes, a cubical-sized refrigerator to do just that. The sound isolating chamber was also kinda cool... and spec sheets of the x33 demonstrator.
Thinking back on what I worked with, it was far more impressive than I realized at the time. We had 15 foot custom cables to connect the 125+ pin flight computer (four of them) to our test system. The test system also controlled the environment chamber, which had like 90 minute cycles from -70C to 50C but it also had a vibration table that has incredible acceleration. I believe it could reach near vacuum, and pressurize, I don't remember how much.
Cubicle size - yeah that checks out. The other thing I remember about ours that it was extremely tall. And blue
