I hope you realize almost if not every phone manufacturer uses child labor.
This childish Apple vs Google/Android/Microsoft mentality doesn't help anyone.

Germany is spending 10x more money and therefore energy, ressources, manpower on choclate, than on basic research.
How baby can steps be?

Progress isn’t composed of grand flashy easily tangible things. It’s hard work and a series of small impactful steps. Iteration is key.

Doesnt that all assume complete combustion? I didnt see the burn off take place but i can imagine a burn done in an open field on stuff thats already partially leaked everywhere isnt gonna uniformly heat all that shit to 400C..

Ok, but the enclosure list included prices. It would be helpful to have similar in the electronics BOM. But, then, the electronics part probably isn't for me or most people.

I'm not particularly a photography person but I'd say they are fine. They can be a bit blurred in low light, and maybe they are not as sharp as a 13 pro which I can compare them to.

Good science would include both of those data sets. But with this device even if you were in the mountains the data is being skewed by the vehicle

I built one with a feather board and BME680 (for weather and gas sensor). Still ~$150 with a few add-ons for a “plug and play” (plus programming) option. My neighbor has a Purple Air I can compare to and it comes out pretty close (after some tweaking).
1 x Flanged Weatherproof Enclosure With PG-7 Cable Glands[ID:3931] = $9.95
1 x Adafruit Feather M4 Express - Featuring ATSAMD51 (ATSAMD51 Cortex M4) [ID:3857] = $22.95
1 x Adafruit AirLift FeatherWing – ESP32 WiFi Co-Processor[ID:4264] = $12.95
1 x Adafruit PMSA003I Air Quality Breakout (STEMMA QT / Qwiic) [ID:4632] = $44.95
1 x Adafruit BME680 - Temperature, Humidity, Pressure and Gas Sensor (STEMMA QT) [ID:3660] = $18.95
1 x FeatherWing Doubler - Prototyping Add-on For All Feather Boards[ID:2890] = $7.50
1 x STEMMA QT / Qwiic JST SH 4-pin Cable - 100mm Long[ID:4210] = $0.95
1 x STEMMA QT / Qwiic JST SH 4-pin to Premium Male Headers Cable (150mm Long) [ID:4209] = $0.95
1 x Stacking Headers for Feather - 12-pin and 16-pin female headers[ID:2830] = $1.25
1 x USB A/Micro Cable - 2m[ID:2185] = $4.95
1 x Lithium Ion Polymer Battery Ideal For Feathers - 3.7V 400mAh[ID:3898] = $6.95
1 x STEMMA QT / Qwiic JST SH 4-Pin Cable (50mm Long) [ID:4399] = $0.95
1 x Adafruit Perma-Proto Half-sized Breadboard PCB - Single[ID:1609] = $0.00 —————————————————— Sub-Total: $133.25
Edited to fix weird type size and spacing on the order I copy/pasted.

19 entries is like the BOM size for a tiny homemade LCD display haha. Some of these components are like a couple bucks, in bulk. Switches, buck converters, USB ports, accelerometers, etc. are probably things just lying around the house of this kind of things target audience.
Edit: They'd also likely be able to build their own enclosures with a 3d printer.

It’s basically eq to 3090 from the benchmarks I’ve seen, and the price is nearly the same.
I don’t really understand Nvidias price model anymore and I think most are very confused. The differences between the cards are so minimal. This new 40 generation is pathetic for the price.

Well, of course, but if you didn’t burn any fossil fuels, more than half of the worlds population would probably starve (fertilizer, tractors, distribution, refrigeration, cooking), so there’s that. Like the reality is we’re married to it until something better is developed.

What does that even mean? Pretending it's technology? What?

Pretty sure every other Android phone is also made by child labor. Fairphone is probably going to be the only company where you get a smartphone that is made ethically.
