Anyone know the resolution of the FLIR camera? Specs don't seem to list the thermal camera resolution, only up-res one. The last revision was kind of weak, low-res with a max of only 120°C or so, if memory serves right. The improvement to : -20°C to 400°C is a happy step forward.

Lepton 2.5 is 80x60, Lepton 3.5 is 160x120.

Scroll down for full specifications.

Key property is also thermal sensitivity, which for Lepton 3.5 is <50mK. Better sensitivity and you will be able to see finer gradients or need less temperature gradient to observe.

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 you…

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.

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.

The statement about battery not being replaceable is false. They are replaceable. But the phone body is sealed to deliver the water and dust resistance rating from its technical specs, so opening it is an entire new adventure in itself.

If the manufactures wanted to they could easily make a sealed phone and a sealed battery and just clip them together. The extra thickness of two layers of waterproofing between them is arguable on a fashion phone but irrelevant on a product like this.

My last flip phone had a replaceable battery and was waterproof: the cover had a rubber gasket and you had to use a coin or key to pry it open.

Why are wasps protected in Germany? I understand bees, but what good are wasps for?

Without the wasps crawling into the sugar dispensers at every single outdoor café in Germany all summer long, people would eat the sugar and create a diabetes epidemic. At least that was my impression in Berlin; wasps got all the sugar, Berliners stayed pretty thin for the most part.

Ah, this explains the bitterness of Berliners

Despite their aggression and desire for sugar, wasps are useful and important pollinators the same way that bees are.

They also annihilate the bees which are much better pollinators

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 camer…

> 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 co…

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.

Does ITAR present an impediment even if it’s manufactured and sold in the US?

You can't take it out of country without an export license- Someone else will have to comment on the process of doing that so they can take their camera on vacation or something I've had to navigate that and make use of listed exemptions to that, for sending thermal cameras i bought from israel- BACK to israel for repair- because of ITAR. Other than that, you can do what you want in-country with a high quality therma…

I brought a 640 x 480 ThermApp Pro with me on vacation to Buenos Aires recently. This might come as a surprise to you, but no one asked me about my camera's frame rate :P

Hey, wait... are you the person on the EEV Blog Forum who wrote about your saga of trying to figure out how to legally ship your camera to Israel for repair? That was also a ThermApp, no?

I've had the competition's ruggedized android phone with a flir camera for a couple of years now? [1] [1] https://www.aliexpress.com/item/4001227941445.html I don't love it like I did the nokia n900 but it is decent. It's an android that goes underwater, can take photos there and you can drop without being worried about breaking it including the screen - all phones should be like that. The flir camera pics look just…

> all phones should be like that. No, let's have some choice. You pay for the ruggedness in size, weight and aesthetics. That's not a trade-off everyone wants to make.

I think maybe you're confusing the expression of an ideal with making a particular implentation toward it mandatory?

> European hornets are not aggressive at all, they are just big and loud. Seems like you are talking about bombus, not vespa. The worst thing about hornets is that if one insect has bit you somewhere near their nest than you better run as fast as possible from that place because of pheromone mark.

I am talking about vespa crabro, the European hornet. All social wasps use pheromones to mark intruders. If you are being stung while close to a nest, yes, do walk away. That being said, I have been stung once (own mistake) while standing 2 meters away from a nest and nothing happened.

Curious. The reason I mentioned nests being close together upthread is because - per my understanding - both being stung by a wasp/hornet and killing one releases pheromones that makes other wasps/hornets go into aggressive mode. So I'm imagining the two nests being so close to each other will, eventually, trigger a war, which only ends once one of the side is eradicated. I wouldn't want to see anything like that near my house.
