I bought a phone with a heat camera and now I know exactly how hot my pizza is

None of these cameras measure things in Kelvin, the only temperature scale that matters. Disappointing.
- They do actually, it's just that they convert it to Celsius right before displaying the value on the screen
  
  It doesn't count if you can't see it!
  Kelvin is the only legitimate way to measure temperature. Everything else is trivia. Duh.
  Edit: I don't have time for your downvotes. It's 277 degrees outside and I don't have a clean sweater.

Used to have one of these too.
- not what I expected to see in the comments of this post
  
  On the contrary, this is exactly what I expected to see in the comments of this post.
  
  How about that? Did you expect a hamster in infrared?
  No.
  Nobody ever does....
  ....sigh.

Just because nobody asked:
- Actually I was just about to
- That's some hot ass pussy!
- Love that curious raised ear. Did you also measure how much of a good boy they are?

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:
- Ooh that's pretty rad!
- what phone is this?
  
  Ulefone Armour 27T pro.
  You can even skip some gym days because the bugger weighs half a kilo.

Looking for a phone with this, a Geiger counter, and a light spectrum analyzer
Also a hardware keyboard, headphone jack, and runs Linux
- Ok so you want a cyberdeck
- It also needs to be under $50
  
  If I'm paying a subscription fee over 10 bucks a month the carrier should subsidize the cost
- That office has headphone jack and 2 sim slots, and some physical buttons for using the phone when it’s wet or under water, oh and a laser level, etc

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!
- d'oh

How hot is your toilet water please.
- Are you sure you're dull? This is thrilling
  
  A picture is worth a thousand words.
  
  Equilibrium is restored.
  
  Cool
- Before and after the deed
  
  An important aspect to specify. Good thinking!

Check where the heat loss is occurring in your house.
- For fucks sake
  
  I can't believe you've done this
  
  Is this loss?
  
  This post has been stellar.
  
  I'm so sorry for your heat :(
  
  what the fuck lol
  
  I don't get it. What is that?
  Edit: For those that don't know, they are referencing a meme . If you don't know the meme, you probably won't find it funny.
  
  Well lost, man, well lost.

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.

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.
- Ah sorry, it's a second hand CAT s62
  
  Okay, nice. So it is the same one I was looking at. Cool, but "bummer" at the same time. Was hoping there was a current/supported model with FLIR.
- What phone?!
  
  Sorry for the Amazon link, but CAT no longer makes phones as of April 2024 so I can't link to their website (which no longer exists):
  It's the S62 Rugged smartphone. https://www.amazon.com/CAT-PHONES-S62-Rugged-Smartphone/dp/B08YR66D1H
- There's a few models with thermal cameras, my doogee gt31v has one. I think ulefone and unihertz have models with them.
  Don't expect software updates.

Coolest thing to look at is running tap water, switch from hot to cold

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.

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".
- No wheels or topics here, but a whole collection of hot sauces straight from the fridge
  A drop of Tha Bomb: Beyond Insanity on a plate also looks quite disappointing
  However, put some of that straight into my mouth and let me tell you, I'm in a world of regrets right now.
  
  Thank you for your service to our entertainment
  
  I think I need an FLIR camera now lol
  
  Brilliant, thank you :)

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
- My go to is to upside-down spray canned air at the PCB. once the canned air boils off, it leaves a layer of frost and you can immediately tell what is hot because it melts the frost.
  
  That’s a good one, I will add that to the repertoire
- My house is entirely made out of brick, I doubt it'll be very effective here but I'll definitely check
  
  I don’t think a brick house has studs

Totally random thought, but check the temp of different things both directly, and also in a mirror reflection. I wonder if it'll sense the same temperature via a mirror reflection...
- Works great!
  
  If you actually want to measure a glass surface, stick a bit of painters tape or other tape with a rough-ish surface to it.
  
  Cool! Or, warm, I guess I should say.. 👍
- I definitely noticed some objects like a coke can reflecting heat from nearby sources. Let me check my mirror
  
  Fun fact: the heat measured is just infrared light, which tell you the objects temperature with the principles of Black Body Radiation, so if an object is reflective, it most likely also reflects infrared and you will see the reflected objects temperature.
  If your first thought was "wait, infrared like tv remotes?" Yes! Point the tv remote at your camera to see how "hot" it gets (it's not hot but it's sending a lot of infrared through other means)
- It is pretty much like taking a normal picture of a mirror.

If you have a pet that isnt allowed on the bed but you know she gets on it when you are not there, now you have the tools to get that proof. >=)

Balls... First thing I would check LOL
- First thing I sent to my gf of course, but not posting here. She said it was the best dick pic she'd ever received
  
  Don't post the pic, but what's the temp difference of balls to the rest of you?

Corners of rooms, especially outside corners and wall sections behind furniture and then compare them with the dew point in the room.
https://www.calculator.net/dew-point-calculator.html
If the walls are colder than the dew point, you'll get condensation.
- Should be about 90°
  
  Take your vote and get out.
- I'm dealing with this exact issue right now. I don't have thermal imaging, but I used an IR thermometer and recorded temps as much as ten degrees lower in the places with water staining than in other parts of the wall/room/house. Any tips for finding the leaks/improving insulation? Right now my best idea is cutting holes in each cavity and blowing in insulation, but I'm not an expert at all.
  
  Nah, sorry. So far I've only been living in houses made from stone and concrete, I have no experience with improving insulation in framed buildings. Someone else, maybe. Sound like just adding insulation isn't a great idea though as that will push the dew point into the wall. You'd have to separate the insulation layer from the humid air inside at the same time, otherwise you'd just get the water in the insulation and therefore wet insulation and mold.

How warm is your empty chair after you've sat in it for an hour
- Update: I sat on the side of the cold bed for 5 minutes
  
  I'm guessing you're a guy .... or you had a heated accident after that hot sauce
  This is the most thrilling dullness I've seen in the community ... thank you for your service.
  
  And that's how my dog learned that silently sneaking off the couch a few seconds before I entered the room weirdly didn't cut it anymore one day.
- That's hot
  
  Was that your bed after lying on it ... or do you just have a misshapen butt?

And here I am using an IR thermometer like a cave man
- Any IR thermometer is a thermal camera with enough patience and a few color pencils.

I want a phone with a thermal imager but I'm worried it would be a shit phone if I did because it'll be a 10 year old industrial affair
- How important is it to have it built in? Could just get a FLIR add-on module
- Yeah. There's also separate cameras you can get that plug in with usb-c to the side of your phone.

Check your ceiling and walls.
- That's a really neat idea for a horror device. You can see evidence of the creature(s) in your walls, but it's very blurry (heat signature spreads out when moving through the drywall), and also delayed (takes time to radiate from warm spots, and also to form new spots).
  I'd love to try making a horror game with that angle, but ADHD has me by the balls 😞

Look at IR reflections on matte steel surfaces - you'll probably find that the longer wavelengths get reflected quite well on a surface that is matte in visible light.
- Ooh let me see if I have any at all
  
  Stainless steel surfaces in the kitchen are usually a candidate - kitchen hood, front panel of the oven, the side of the microwave, the freezer, something like that.

I bought one just to check equipment after I've run it all day. Checking the baler and combine for bad bearings periodically will hopefully prevent an expensive fire.

About 70% of your pizza is 70° hot!

I found an uninsulated stud space in my friend's house using one of these. He couldn't figure out why the room was always cold, they are neat

I have a FLIR camera too and my gas range runs at 250°C confirm?
- What's a gas range?
  
  A pipe and storage network for distribution of CH4?
  
  If I'd have to guess, I'd say from about up here to down there:
  
  Gas stove

I’ve seen FLIR thermal cam attachments for your phone not but a phone itself. Is that what you mean?
- No, it's a CAT s62 phone with built in FLIR
  
  $300 for a phone with flir sounds like a good deal considering flir cameras are 300 and up
- Example
  
  Holy shit that thing is nuts

I would have endless amounts of fun with this

Great way to check for roof leaks after a rain

I have 3 glassbottles in my fridge, that I use for filling up my water bottle I carry around. I have a pixel 8 pro with a thermometer. And I use it to check which bottle have the coldest water if Iam I doubt.

The water coming out of the shower head or faucet when it’s warm enough to be comfortable, but not so hot that it’s scalding.

hot Hot HOT!

I've seen these added onto phones, but you bought a phone WITH it already on board? That's sick. I've not seen anything like that in years... They just keep pumping out bullshit over and over again, year after year.

I really wish this was how the thermometer on the pixel phones worked, I'd actually use it then.
I mean it's nice not having to keep track of a dedicated thermometer, but it's such a hastle to use.

Write "HI" with sunscreen on your chest and take a pic of your shirtless self with the heat camera
- Wouldn't that work for a UV camera, not an IR camera?
  
  As an armchair scientist .... I have no idea what I'm talking about ... but you're probably right.

Check for the cabels and outlets to see if there is anything wrong with the electrics in your home

Pixel8 has a thermometer built in.
- Shit. Now I want an 8. It'd help me figure out where the drafts are coming from in the house

Pacman reference

This makes me think of my pizza from Saturday. We ordered Mod, so my wife and I got individual pizzas. I didn't grab them well from the delivery guy, and they went upside down off the porch. Mine was out of the box, upside down in the snow.
You know what? I ate it anyway.
- Everyone knows snow is sterile, so you don't even need the 5 second rule
