@futurebird @sunpig one of my colleagues has one that docks to his iPhone (they make android ones too), "only" a hundred or two for a decent one! (he has it for electrical work, looking for hot wires/breakers and such) I really really really want a wearable FLIR. Something about the thought of seeing the world in a different spectrum while in otherwise total darkness does things to my reptile brain.

@futurebird @sunpig You can probably buy a low-end IR camera, rather than renting one. They're not cheap, but they cost less than, say, a mid-range smartphone. When we moved house, I bought an earlier version of this: https://www.idealo.co.uk/compare/4862822/flir-one-gen-3-for-android-435-0005-03.html Predictably, I wanted to use it to find hot spots on the outside of the house and cold spots on the inside to help focus our insulation efforts. Interpreting images is harder than I imagined, because the amount of IR radiated by an object depends on the nature of the surface and not only on its temperature. You'll be familiar with black-body radiation and the effect of an object's colour on the amount of heat it radiates, but there are other factors that I haven't fully got to grips with. If you just point the camera at your house and look for the yellowest part of the picture, it'll mislead you. The camera I bought is not compatible with a modern phone. I'm tempted to buy a new one, because they're fun to play with. For instance, it would be interesting to see how much heat is generated, and how it's dissipated, when I charge the car overnight.
