When choosing a thermal camera, you need to consider the quality of the matrix, especially the pixel size, the generation of the matrix too - whether it has an analog output, digital output or combined, and the new ones have a built-in ADC. Also, in addition to the resolution and fps - the physical shutter mechanism is important, if one is supported. I say all this because it depends on this whether your camera will show the truth, or will invent results that are far from the truth, but look good in a picture. All these features play a role in the design of the camera. If some are compromised, poor or missing, do not hope for representative results, because software alone is not enough, you also need the superior hardware from the matrix. FLIR are the best in this regard, and their products calibrate every 10 seconds or when needed, based on the position of the camera. They successfully cope with problematic surfaces, Surface emissivity, glossy surfaces, covered ones etc. FLIR has a solid concept for lens calibration and compensation. In addition, the thermal management of the sensor itself is very well done, which means in simple words that not only does it measure the thermal radiation from the object to the sensor/matrix, but it also compensates for the radiation from the sensor/matrix to the object. As far as I know, Infiray models also use FLIR matrices, but older models. Still with a good pixel size. Other good cameras besides FLIR are FLUKE. But I don't know how the calibration and compensation is done in their sensors and software. Regarding this IR camera you suggested - it is very far from a quality product.

I do like and use such radar-lights though. Yes, maybe a bit unpredictable when they start to work but most times I walk into the livingroom, the light in the kitchen starts, or when I enter the room from the other side. I also have them on other places inside the house. It is just nice to have them on when entering a room even before opening the door in many cases.
With PIR you need to step into the beam first.
For the camera, I would just wrap wire around it for the needed stiff-length. I have another (much more expensive) one and it is a bit too stiff in many cases to use since it is that for the whole length. I might just add one to my basket one next time.
Biggest problem with all those items. in total still a lot of money and I'll need a bigger house for all this tools you show!

Boeing uses similar tech for the window shades on the 787s and get darker, not the white opaque color of these. But has varying degrees of darkness and in my experience, even when fully dimmed they still let in too much light. I prefer the old slide down window shades, but this tech has been around for a while now. Good review though, nice to see how these AE shades work. I wouldn't worry about the power factor, yeah it was shit but how many watts was it using and how many amps were lost Could cost more in making an active PF correction module than you'll ever get back from the savings. Not to mention since everyone said these are capacitive, it will help offset all your motor inductive VArs. Which by far there is more inductive loads than capacitive loads in a house.

I saw a Makita fan jacket on Rinoa's last video, but it was probably heating rather than cooling. otherwise why would it have sleeves in the first place
These window privacy screens are way too cool. PDLC stands for polymer dispersed liquid crystals, which kinda makes sense and it may be worth experimenting with adding a polarizing filter to the foil, maybe you can achieve almost 100% opacity this way but that's just my wild guess. The link appears dead though.
Had one of those endoscope cameras for a bunch of years with inspecting the sewage plumbing in mind. Not really up for the job.

I bought a fan jacket in Japan about 2 years ago cuz it was so dang hot. I love it. It is a long sleeve, plugs into any usb powerbank. I chose a lower powered option because I didn't want to be locked into some proprietary battery system.
It is funny cuz it was a very new thing even in Japan so you'd get weird looks.
My sister wore it and i lagged behind looking at something and while catching up i heard some older guys point and basically said woah fat! in Japanese. It was pretty funny.
And i just checked the tag and obviously it is made it China.

Btw, I got one of those unbranded endoscopes a few years ago, lasted a while then one day a few months ago it stopped working. Today after this video I decided to peak inside the little dimmer box and turns out the wires coming from the USB side broke off; not all, just the green and the black ones; you think it would be safe to just re-solder them to the pads based on checking which makes the multimeter short-test beep for the corresponding wire color on the other side, or is there a big risk of damaging my computer if turns out it's less obvious than it seems

I actually have been looking through aliexpress thermal cameras a lot lately and i've been asking myself how much resolution is enough to find shorted smd components What would you say
Also i found out that ai has introduced itsself another time unwantedly in here as we have sellers advertising 512x512px resolution cameras only to find out after scrolling that it uses the same 256x192px sensor as the other options it compares itself to, just upscaled by their fancy thermal imaging engine gear go brrrr ai thanks. Lets fck up comparability all over again

Great video as always. Would mention though that when checking car battery you need to take the leads off if you see a low functional reading as the ESR is done via k probe (as i am sure you know) but having the the clips onto the terminals directly may actually give you a different reading at times and in fact indicate a bad conduction between them. Also these units will not indicate an inter cell stitch failure, you need to actually use a proper load box for that, just in case you're venturing out into the wilderness.

I am officially done with AliExpress. The platform used to be really good at dealing with issues that cropped up like missing parcels and bad sellers. That is no longer true. I’ve now lost over $150 in completely bogus AE judgements on cases.
As a hobbyist, I’ve spent thousands on the platform over the years. But trust is important. If I cannot trust the platform to make good decisions in handling bad sellers and shipping problems, it becomes too risky.

I bought a lightbulb that worked when you have a power cut.
How it worked was that it had a rechargable battery that charged up when you used the light, then sensed of there was a power cut, and when there were it used the battery to powet up.
We have freqent powercut, and it worked perfectly for 2 month, then the first stoped working, 3 month in the second also stoped working. (We had about 5 powercuts during that period)

I bought some radar type motion sensor LED bulbs at a hardware store here in Canada for about the same price. I have them indoors but I prefer PIR type motion detectors because the radar picks up movement through walls.
The simple solution for the floppy endoscope wire is to wrap a piece of solid (not stranded) wire around it and use tape or heat shrink every 10 or 12 cm to keep it from unravelling.

you can probobly disconnect the ldr to get it to work with lights on and it looks like a component is missing i would guess that placing different value resitor there would change the sensitivity at least other radar board has both these options tho they come without the ldr but has a ldr sombol where is should be mounted
keep up the good work
cheers!

4: 08 the biggest problem I can see with the vest is that in a dusty climate (like the Australian bush for example) the fans are just going to suck in so much dust and absolutely plaster your back with it. Or your mates might get the 'fun idea' to throw some dirt at you for the same affect. Still a very cool vest but I think something to be weary of.

A bit more on the pricey side, but I've really enjoyed the Doogee smart phone thermal camera. It's got good resolution & refresh rate it does the overlay. Ontop of having night vision & it just being an android smartphone. So downloading videos off of it is a breeze. I want to say I got mine for $200 during a sale I want to say it's a v20 something.

I bought the infiray p2 pro, then they updated the app, and now the app wont correctly work on my phone! infiray WONT reply to any emails so they have had my money and effectively 'bricked' my device. If you decide to give your moeny to such a company, check phone comapatbility first, but as you see from my story thats no gtee against updates.

I have two questions about the thermal camers: (a) I read somewhere that the 240x240 cameras used interpolation from a sensor with much less resolution, what's your impression Is it true 240x240 and (b) can it be connected to a PC for live images or does it just work as a storage medium with access to saved images on the camera itself

Regarding the endoscope, I just ordered one as well, but one of the very few with 3, 3mm and a fairly high resolution of 1280x960.
With 14 a little bit more expensive, but surprisingly good image quality.
The downside is, that the camera itself heats up very fast, so better bring some time to occasionally let it cool down.

I have that exact same endoscope camera. You definitely get what you pay for with it. For such a cheap price it can be rather useful for certain tasks where close up image is necessary as the picture quality while not amazing is much better for close up viewing. However it's limited picture quality definitely limits it's use case.

Why are you continuesly listing the discount prices for new members on these seller platforms
Everyone that already has an account there or that wants to order multiple items won’t get that discount. Or do you suggest creating a new account everytime
Tnx for the content of the video. Really like that.

I always saw the Flir visible light camera overlay as a gimmick to augment their tiny sensors. For 400 USD I got a Seek phone-dongle thing that has a 320x240 sensor and a 15hz frame rate. With the much larger sensor, faster frame rate, and the ability to adjust the focus, I find it very useful.
