Made my own DIY thermal camera using a Raspberry PI and a FLIR Lepton module. Has great resolution for the price point and works quite well. Started working on a Node.js module that can interface directly with the module, which seems to be somewhat working.
I nabbed the LeptonModule source and hacked up some additional features for locking the temperature range scale, which is super useful for getting a visual on something, locking the range, and then looking at other objects for comparison to what you locked on.
Also attempted to use Math™ to figure out the temperature of the center pixel, but that seems to be much more difficult to get accurate. There are a lot of variables, such as sensor temperature, ambient temperature, FFC calibration, etc. But using an IR thermometer, I was able to get it within a few decrees C at room temperature, so that’s good enough for a me.
