Someone needs to build a phone that is leaning towards a tricorder; I'd buy that for myself and my kids. My Pixel 10 has a temp sensor on it, which is cool, but I've had minimal use so far.

I've always wanted to build a tricorder with my son, was just thinking about it last week when he was putting together a digital compass (with RasPi Nano, magnetic sensor, GPS, and LED light ring + OLED).

Take a look at the phyphox app - https://phyphox.org/

Wow! That app is amazing thanks for sharing

This is brilliant.

Caterpillar has a smartphone with a thermal camera. The price isn't far off the the price of the most expensive smartphones

how does Cat's self repair policy compare to John Deere's? Then again, it's not far off from Apple's

There are also cheap ($200-$400 range) usb-c thermal cameras specifically for phone use (they're cheap because they're just a sensor, the app on the phone is the "screen" and controls.) Great for narrowing down overheating hardware, and you can keep one in a pocket.

Thermal is interesting, but hyperspectral is much wider than just thermal. The two are not the same.

I want both :)

I will say I have a FLIR C5 dedicated thermal camera, which I got used off Ebay for ~$300, and it's pretty useful to have around as a DIYer.
