Hi,
just wanted to share my desktop thermal camera build. It's based on a ThermalEye 3500AS core I got for nearly nothing a few years ago. That core is intended for security applications and so on. The resolution is not that great, only 160x120, but it's good enough for close up work. The focus is adjustable and the camera outputs 30Hz, which is quite nice.
Other components used are a Raspberry Pi3 + Display and one of those cheap VTOP USB capture devices.
I might add a Pi Camera module for a MSX like vision later, is there any open source software for that? I'll wire the control interface up to see what I can get out of the camera (and to change modes).
The image looks way better on the local screen.
