diy-thermocam VS diycamera

Agree. I think it depends on the use-case (and a personal interest in open-source and DIY stuff) which solution is the best.

For example with the open serial protocol of the DIY-Thermocam, you can build your own software applications in Python, Typescript, etc. to cover use-cases that are not part of any standalone solution (https://www.diy-thermocam.net/docs/serial/).

And if you are familiar with Arduino microcontrollers, you can change the firmware as you wish and extend it with new capabilities as well (https://github.com/maxritter/diy-thermocam/tree/master/firmw...).

That would be really neat, but I haven't seen anyone even make a CMOS imager on SKY130.

One could make an array of thermopiles, like the hacker that made their own imager out of discrete diodes (digiOBSCURA) . But each pixel would cost $7.

One might be able to make an array of thermistors (possibly with active cooling using a peltier) like the diycamera (digiOBSCURA) below. Might be an application of combining many RC oscillators in a tree and recovering the signal with an FFT. I have a gut feeling this is possible, but haven't show it.

One could experiment with microbolometers on tinytapeout. https://elicit.org/search?q=cmos+microbolometer
