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.

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.
