I bet by changing up the sensor pixels this would be a pretty cost effective way of making a low res FLIR camera, or really any imaging band. Using a different pin hole you might even be able to image things with xrays, neutrons, or strong 100Ghz through THz radio waves.

Fun and a great learning experience, sure. But, at least with respect to infrared, I'm not seeing the cost effective part when fully integrated solutions with ~19x greater resolution and then some can be had for $400 retail; the BOM for such a project will approach (if not exceed) this figure. Prototyping is often deceptively expensive.

Certain FLIR resolutions beyond a certain density are, let's just say, not unlike the early days of cryptography.
