Dull Men's Club

Just because nobody asked:

Used to have one of these too.

I have a phone with a thermal imager too!

I mostly use it to brag to people about how I have a phone with a thermal imager!

But here is a demonstration that glass will reflect a bit of thermal radiation, but is completely opaque to thermal behind it:

As long as you aren't touching the glass, wherein the glass will conduct your thermal signature:

And then if you take the hand away, the signature remains on the glass for several minutes!

As a bonus, my phone also has a microscope, and I learned that my facial hair is sometimes triangular:

Looking for a phone with this, a Geiger counter, and a light spectrum analyzer

Also a hardware keyboard, headphone jack, and runs Linux

How hot is your toilet water please.

Check where the heat loss is occurring in your house.

You can't not say what phone has FLIR. Need details please! lol

There was a discontinued (and discounted) CAT phone I was looking at a while back. The phone itself was mostly unimpressive, but it did have a decent FLIR camera which is why I was looking at it.

None of these cameras measure things in Kelvin, the only temperature scale that matters. Disappointing.

I'm so glad I don't have one. I can't imagine the amount of time I'd waste play acting splinter cell.

too bad they never released a game after chaos theory.

Do you own any "Hot Wheels" toy cars? If so, how hot actually are those wheels?

In the absence of "Hot Wheels" toy cars, I'd also be interested in other objects which claim to be hot, but likely aren't i.e. a "Hot Topic" clothing item, or bottle of "Hot Sauce".

you can sometimes use these as a stud finder, depends on the wall

If you ever do electronics repair and are good at soldering these are a lifesaver for quick diagnosis if the resolution is high enough. Look at the board, apply power, and the part that is shorting out will often quickly get stupid hot. Sometimes it will be a complex repair you can’t easily do like a bga chip but you’d be surprised how often it’s just a random capacitor that went bad in your phone or switch or whatever and swapping it out (or even just getting rid of it if it’s an extra filter) fixes the issue. The hard part is finding out the value bc there are never schematics

A less easy to use alternative to this that I use bc thermal cams are expensive is squirt isopropyl alcohol or flux on the board and apply power. It’ll boil at the point where the part is shorting. Harder to determine but much cheaper. If you already have the camera though

Now, this technology is new to me, but I believe that's Homer Simpson in the oven, rotating slowly. His body temperature has risen to 400 degrees. He's literally stewing in his own juices!

Go around the house and look at all your outlets. You’ll find that GFCI outlets put out a small amount of heat. (Something to do with their function that is unavoidable.) Regular outlets that are warm and under no load may require investigation.
You can also spot heating conduits in walls, roughly figure out what power adapters are not very efficient, and even use them to gauge how well heated blankets and the like are working. I used mine to look at studs in the wall to figure out (well, be certain about) how some old renovations were handled.
