42cm of work distance? That’s pretty good

The company sells professional dentist equipment. There are better devices: https://s.click.aliexpress.com/e/_AVEvM7 (up to 6x magnification) 4-5 times more expensive, though...

I wonder if this camera/light arm will finally solve my problem with lighting or camera mount.

Something I did not think about, but what can be quite useful: https://s.click.aliexpress.com/e/_9zY8DH No battery needed.

And I'm thinking about this sprouting machine

   

We added sprouts to our food, and this thing should (theoretically) simplify and accelerate the whole process.

Another device for today: Air Quality Detector PM2.5 PM10 PM1.0 Indoor Portable LCD Air Quality Test formaldehyde Detector Gas Detector PM2.5 HCHO TVOC

Can be very interesting for the working-from-home environment.

The monitor arms have arrived! Took a week. Haven't assembled them yet, but they are heavy!

The first one went to my wife's monitor. Ordered two more! 😆

Just arrived. Interesting device, playing with it now. Looks like air purifiers do work!

I recently watched a documentary on national TV about pollution measuring devices included in the EU network of certified surveyors. Each device for measuring one type of particle in dedicated "pollution measurement station" (we have it several n my town) cost 10,000 + euros.
The documentary was triggered by wrong pollution data for some EU cities posted by some seller of similar equipment like yours. So, be careful with readings of that device.
In my city/country, we have EU accredited institute for pollution measurement, and measured data is public, published on a web site.

It's all about expectations. I do not care if the result is, say, 5% off. 20 degrees, 21 or 19? Not a big deal, e.g., if you sit next to this device, it will show 1 degree more. What's more important is the tendency. I closed the window - the level dropped or increased? I turned on the heating, what happens?

10,000 euro devices can measure up to 0.001%, what for me makes no sense.

Do they have any measurements related to my living room? 😉
