I made a tiny thermal camera with a Tinyscreen+ and an AMG Grideye sensor from Adafruit. Three of the buttons are used: to control the colormap, the interpolation mode, and emphasis. It has a pretty good framerate. It needs a 3d printed case, but I haven't got that far. Here is a picture and some code.

Hey John,

This is awesome!

If you wanted to make this project tinier, TinyCircuits now has a Wireling version of the thermal camera board used in this project: https://tinycircuits.com/collections/wireling-sensors/products/ir-thermal-camera-wireling
