I used the S62 as a daily driver for a couple of years and it was fairly decent. The convenience of having a thermal camera in your pocket at all times was remarkable, and it's one of those things you kind of miss when it's gone (my daily use for it was checking if the coffee was cool enough to drink--yes, I know my tasting organs provide much of the same functionality...) However, the resolution of the thermal camera wasn't particularly great, and the 9 fps refresh rate was also a bit limiting. Still, for checking for drafts, occasional electronics repairs and a general party trick it was great.

Eventually I got a new phone from work, which I grudgingly accepted since I wanted Android 12 and a better visible-light camera, but I missed the thermal cam sufficiently that I got an Infiray P2 off Ali as a plug-in substitute. The resolution and refresh rate are a lot better than the Cat, but having to carry an extra dongle (and plugging it in, starting the app, restarting the app when it crashes...) sometimes makes me consider going back. If/when Cat makes a successor, I'd be very tempted to get it.

Using a thermal camera in the kitchen is under-rated. I sometimes do the same.

Was inspired by this old linux.conf.au talk (that I attended in person) about a microwave with a thermal camera in the top. I would love the same above my kitchen stove: https://www.youtube.com/watch?v=R3DADx5z-XY

I'm a die-hard iPhone user so sadly a built-in won't work for me. I currently have a first generation Lightning FLIR One.

It's pretty limited, only a single temperature measurement, no min/max scale you can see (it just auto calibrates), has a terrible rechargable battery and doesn't work with an iPhone case.. but I got it for the bargain basement price of $100 AUD ($67 USD) on Marketplace.

My interest is more related to home effeciency (looking at gaps in insulation etc) but has been fun in the kitchen too.

I'd love one of the newer ones but haven't wanted to justify the cost and happy with my bargain aquisiton :)

You can buy a stove that uses probes to monitor the temps and hold/stick to a preset program https://www.breville.com/us/en/products/commercial/cmc850.ht...

I can't wait for these to become more mainstream so recipes start listing "Set stove to 150c" rather than "to medium" which is widely different depending on what stove you use. An amusing story one youtuber shared was the followed some advice that said to set your stove to high and leave it for 10 mins first, advice meant for a gas stove. When they tried it on an electric stove, the oil ignited on contact with the pan.

> advice meant for a gas stove

Can't imagine it would be any different result. 10 minutes preheat on any range is a lot. My cast iron pan started turning silvery blue well before the 10 minute mark with my gas range on high.

Re:Caterpillar offers phone with built-in FLIR camera by rodgerd on Tuesday December 06, 2022 @09:43PM (#33890067)
Some induction tops have similar functionality - measuring the temperature of the pan and keeping at that temperature. It's not as precise as a probe, of course, but it's extremely convenient and useful.
Re:Caterpillar offers phone with built-in FLIR camera by m463 on Wednesday December 07, 2022 @02:24PM (#33898956)
I have used a control freak (mentioned above).

All the induction cooktops I've used (both builtin and plug-in) have been REALLY useless at temperature control. Even the heat settings leave a lot to be desired, they are very coarse.

The control freak is orders of magnitude better at temperature control. I suspect it is not only the design and quality of the sensors, but the algorithms used to maintain the temperature (probably good PID).

There are two sensors:

a small glass covered sensor built into the center of the heating element that is spring-loaded and gets the heat off the bottom of the pan.

a second plug-in sensor with a cable, that can be attached to the side of a pot using an insulator gadget and suspended in the middle of whatever you're cooking.

Another pretty critical part is the "programs" you can write.

For example, you could make a "hamburger" program to bring the pan up to temperature, then beep to add the burger, then flip it later, then remove it and do another.

Do you have experience with such a hob? I'd like to get one, but have found little info except marketing from manufacturers.

I would assume those would be mostly useful for frying/searing meat, vegetables, and eggs with little oil. As soon as you have more liquid in the pot you won't be able to control the temperature by measuring the temp at the bottom.

Do they work well with different pans?

> As soon as you have more liquid in the pot you won't be able to control the temperature by measuring the temp at the bottom.

That sounds like an interesting engineering challenge! Assuming we have a stove with a fast-acting heat source (e.g. induction) and high-frequency thermometer (> 1 Hz), what can we learn about the contents of the pot/pan?

I'm thinking: dump a set amount of energy into the pan (say, 0.5 seconds at "power boost" level), then watch the thermometer. Do it several times, with varying pulse lengths (say, 0.1 to 1 second - you don't want to burn anything on the pan, nor wait too long for it to cool down). This should give you a good idea of the pan's step and impulse response, and - I think - you could guesstimate what its contents are - particularly, if there are any liquids in it, and what they are. Then, continue with normal cooking, but keep a continuous record of power output vs. temperature measurement, and possibly occasionally pause and do a round of such pulse tests again.

I see no obvious reason this wouldn't give a stove quite good control authority even in the presence of liquids, including those that are added or naturally seep out during cooking. I also don't expect any of the appliance companies to ever include this level of sophistication in their products.

Re:Caterpillar offers phone with built-in FLIR camera by zejn on Wednesday December 07, 2022 @10:42AM (#33895620)
Actually, I have a portable induction stove that I can set the temperature and it kind of works exactly the way you described it.
Re:Caterpillar offers phone with built-in FLIR camera by rodgerd on Thursday December 08, 2022 @03:17PM (#33912739)
I do. I've got a Panasonic hob that's got two types of sensor: one which covers ranges of 140-220 C, and one which covers 60-120.

I find it very convenient. It's not perfect, because of course a sensor looking at the bottom of a pan can't be, but in practice we've found it very handy for the boil function (bring water to a boil @ 100 deg, drop back to 95 and hold there; making candy/fudge that requires holding around 80 degrees, making proper custard for things like creme caramel. The higher temperatures are good for things like dealing with meats, since I can dial in a temp and not fuss over what's going on.

The thing that has surprised me is how relaxing it is to use - as I say, I feel as though I'm fussing over what I'm cooking less.

That said, they're accurate to only 5 degree increments at best, and I wouldn't try using them for something like a sous-vide replacement.

Re:Caterpillar offers phone with built-in FLIR camera by amelius on Wednesday December 07, 2022 @06:11AM (#33893061)
Yes, I'm wondering how well these temperature measurements work with metallic surfaces that are almost fully reflective.
Re:Caterpillar offers phone with built-in FLIR camera by lathiat on Tuesday December 06, 2022 @10:07PM (#33890186)
Particularly useful for "fast heat-up" combined with "don't fry the pan"

Serious cooking books always focus on reproducibility and actual processes happening at certain temperatures in your food.
Re:Caterpillar offers phone with built-in FLIR camera by TeMPOraL on Wednesday December 07, 2022 @04:30AM (#33892375)
Any recommendations? Can't think of any such book owned by anyone I know.

I often jest that cooking is just process chemistry, but done without proper tools and without caring about quality of the outcome.

I've been using a BlackView 9900 Pro for over a year, and attest to the surprising usefulness of the built-in thermal camera, such as checking how well food is heated after microwaving, or even watching the heat distribution of rolling, boiled water.

My phone's battery is degraded now and I'm dreading a switch to something else. I've eyed the S62 but don't think it's an upgrade.

Re:Caterpillar offers phone with built-in FLIR camera by anigbrowl on Tuesday December 06, 2022 @08:54PM (#33889808)
I'm confused, why not just replace the battery? They're available and if you're not good with fiddly disassembly jobs you can probably find someone to do it relatively cheaply.
Re:Caterpillar offers phone with built-in FLIR camera by whacked_new on Wednesday December 07, 2022 @12:35AM (#33890975)
completely fair, although the BV has a layer of anti-slip rubber on the back panel (which I also came to appreciate), so replacing the battery will probably require ripping that layer off (see https://www.youtube.com/watch?v=zikXifsPDT0 if curious)

that said, I've abused the phone enough that maybe I should find a replacement for the rubber too.

Re:Caterpillar offers phone with built-in FLIR camera by tildef on Tuesday December 06, 2022 @08:51PM (#33889787)
Agreed. I'd hold off a bit if I were you, unless your current battery is completely busted. Might even be worth seeing if you can replace the battery. The S62 is over 2 years old, and considering Cat hasn't updated it past Android 11, they may have something new on the horizon--unless they plan to exit the phone market entirely, of course, which I guess is also a possibility.
Re:Caterpillar offers phone with built-in FLIR camera by msrenee on Wednesday December 07, 2022 @09:17AM (#33894559)
Every Cat phone I've looked at was on the high end of pricing at the time it came out and on the older end of operating systems. I've been in the market for a serious rugged phone basically the whole time I've had cell phones and Cat has never been justifiable to me.

I lucked out and grabbed a Galaxy Xcover pro when they first came out. It's not really advertised for the consumer market, but it was also way cheaper than things I liked less that had been out for a year longer. I'm not sure if they'll come out with a new model anytime soon. I will say this thing has a removable battery, solid construction, and is plenty fast for me (though I'm not picky on speed). I'm still on the original battery and it will play music for 10 hours through my Bluetooth headphones and still have 30% battery by the time I get home. I really have no complaints.

EDIT: the Xcover does not have an IR camera. I got off on a tangent because I keep getting disappointed every time I look into Cat phones.

the 9 FPS I believe are because US manufacturers aren't allowed to export thermal cameras above 9 FPS
Re:Caterpillar offers phone with built-in FLIR camera by bpye on Wednesday December 07, 2022 @12:23AM (#33890897)
Afaik higher FPS cameras can be sold to individuals but are ITAR controlled. I know at one point at least Seek had a higher rate version and anyone could buy it, but you had to provide documentation.
Re:Caterpillar offers phone with built-in FLIR camera by walterbell on Wednesday December 07, 2022 @12:09AM (#33890829)

Re:Caterpillar offers phone with built-in FLIR camera by asddubs on Wednesday December 07, 2022 @12:46AM (#33891041)
yes, but import is the opposite of export
Re:Caterpillar offers phone with built-in FLIR camera by walterbell on Wednesday December 07, 2022 @01:05AM (#33891167)
What matters for US consumers is that both 9fps and 25fps are on Amazon for similar prices, https://news.ycombinator.com/item?id=33890299

>(my daily use for it was checking if the coffee was cool enough to drink--yes, I know my tasting organs provide much of the same functionality...)

For tea I pretty much found the right amount of cooling time once and now I just repeat it. I boil water, steep for 5 minutes (with a timer), then when that 5 minutes is up I remove the bag and start an 18 minute timer. It's still pretty hot but slowly drinkable then, and within a couple minutes can be comfortably consumed quickly as well. I don't even try to drink before my timers are done anymore as I don't want to scald myself.

I think I also did some experimentation with a laser thermometer, but I don't recall what numbers I landed at, and this way I don't need to wonder how long it will take either. The time also lines up pretty well with eating breakfast if done all together.

> my daily use for it was checking if the coffee was cool enough to drink

My wife has the same issue with hot coffee which drives me a little nuts. She uses a normal mug most of the time. Because she isn't certified in coffee temp detection like I am; she waits and waits, gets distracted, and eventually it becomes too cold. So she reheats it in the microwave, usually to the point where it's too hot, and that cycle continues after it gets too cold again. She's probably reheated coffee in the microwave up to 4-5 times a day at times. It's hilarious and ridiculous. As an engineer, admittedly, I enjoy the hilarity so much I'm not sure if I care about it being resolved!

The issue is two-fold:

1) She lets the coffee hit the outermost parts of her lips and subjects herself to getting destroyed by the high temp lol. I don't understand why this is so difficult for people. Your outermost lips are more sensitive. Don't do that. You don't attack hot coffee like it's a fine bourbon. Also you can feel the temp and steam to know not to even attempt based on your preference and tolerance.

2) She isn't sitting at a desk consistently like most of us. She's everywhere in the house and then leaves, and her coffee intake isn't a priority like many of us.

If I put her coffee in a stainless steel mug with a lid, then it takes too long to cool to her temp. She leaves the lid off to cool and then forgets about returning to it in time. And she doesn't end up drinking the coffee because it becomes too cool. So now she would have to transfer to a microwaveable mug to reheat and start that cycle so she doesn't even bother. If I'm prepping her a roadie coffee, I must pour it, leave the lid off for a period of time and then place it back on so she will attempt drinking it in time in the car to commit to it. If it's too hot, she will more than likely just abandon it and not check back in before we reach our destination.

I got her an Ember mug so she can read the actual temp and control it. But it's not dishwasher safe of course. So she doesn't tend to use it. And from the fresh brewed carafe to the Ember still is too hot, unless the lid is off for some time like the stainless steel mug, lol.

The ideal mug for her would thus be an Ember mug that is dishwasher safe and thus have some sort of twist mechanism to disconnect the battery and status/controls portion from the core mug function. And probably have a vent mechanism on the lid (maybe a double pop on the Ember lid to vent more?) to more quickly get the temp down from initial temp, as the heated mug portion can ensure the set temp is hit anyway.

Someone please build that and save me! Or don't, and I'll enjoy the entertainment derived from the struggle. :)

Re:Caterpillar offers phone with built-in FLIR camera by krzyk on Wednesday December 07, 2022 @09:19AM (#33894583)
I also don't like hot coffee (or anything too hot, soups etc.) which drives my wife mad.

Before making coffee I put a cup into the fridge so the coffee will cool faster, I have not issues with cold coffee, I just don't want to wait that long.

I also used to add ice to coffee, but that was diluting it.

Re:Caterpillar offers phone with built-in FLIR camera by prennert on Thursday December 08, 2022 @02:41AM (#33905309)
I used to do this with my Aeropress. I added an icecube on top of the ground coffee and poured boiling water over it. It reduced the temperature from 100°C to about 80°C if I remember correctly. Anyway, it came out ready to drink, and generally you can just brew with less water and then the dilution is not a problem.
Re:Caterpillar offers phone with built-in FLIR camera by tsm on Wednesday December 07, 2022 @05:30AM (#33892781)
Hello, it's me, I have the same coffee problems as your wife. A few things that really helped, used in increasing order of desperation:

1. Buying a temperature-adjustable kettle and making coffee at 185° or so instead of boiling. Bonus: I think the coffee tastes better anyway. I recently moved and couldn't take my fancy kettle with me, so now I pour cold water into the boiling kettle until I guesstimate I'm at 185. I guess this tip doesn't work if you're using a Mr. Coffee machine or whatever.

2. Giving the mug a really good blow as soon as the coffee is poured.

3. My wife bought me a few mugs that are much wider at the top than the bottom, meaning there's more exposed surface area and the coffee cools off quicker.

4. Adding an ice cube.

Re:Caterpillar offers phone with built-in FLIR camera by thexa4 on Wednesday December 07, 2022 @06:29AM (#33893193)
Instead of ice cubes you can also use frozen coffee cubes, it prevents dillution.
Re:Caterpillar offers phone with built-in FLIR camera by pianosaurus on Wednesday December 07, 2022 @07:58AM (#33893820)
Or rocks. I have a set of mineral cubes in my freezer. I don't need them for coffee, since I like it scolding, but they are handy for other drinks I don't want to dilute.
Re:Caterpillar offers phone with built-in FLIR camera by spuz on Wednesday December 07, 2022 @04:32AM (#33892385)
I don't think it exists but it sounds like the best option for you would be a steel mug with a heated baseplate. The baseplate could detect the presence of a full mug with a force sensor and then start heating. When she makes her coffee she could place the mug on the baseplate and then keep it heated at her desired temperature. That way she could run around doing whatever and always have a warm coffee to sip on when she comes back to it.
Re:Caterpillar offers phone with built-in FLIR camera by zejn on Wednesday December 07, 2022 @11:15AM (#33896110)
For the price of washing two mugs instead of one, you can also pour the coffee through air from one to another a couple of times. That brings the temperature down much quicker comparing to just leaving it sit a while.

Helps to have containers that have an edge that is easy to pour from. Less spilling.

Re:Caterpillar offers phone with built-in FLIR camera by throwthroyaboat on Wednesday December 07, 2022 @03:34PM (#33899853)
Same issue with my spouse. Solved it by buying a fancy manual espresso machine, and me learning to steam the milk to the correct temperature by feel. For tea we have an adjustable temperature electric kettle.
Re:Caterpillar offers phone with built-in FLIR camera by kilotaras on Thursday December 08, 2022 @04:23AM (#33905993)
I remember seeing cubes that have solid inside that has melting point around (good temperature to drink coffee).

You put them in a cup and it

1. Quickly cools coffee to that temperature (by increasing temperature and melting). 2. Keeps coffee at that temperature for some point (doesn't go lower until liquid inside is back solid).

I've gave it a cursory google and can't find a name.

Re:Caterpillar offers phone with built-in FLIR camera by jaclaz on Wednesday December 07, 2022 @05:24AM (#33892742)
Maybe something like a magic mug:

could be made with ink/paint changes that show (very approximately) the temperature (I think the ones around have only on/off states).
