Thermal imaging is another one of those technologies that seemed out of reach not so long ago, almost the realm of science fiction as in 1987’s Predator, where a Forward Looking Infrared (FLIR) camera is used for the titular extraterrestrial’s vision.

But as with so much other tech, access to infrared thermography has been democratized over time, with a great example being the Teensy 4.1-based DIY-Thermocam V3. In addition to a 3.2″ TFT LCD touchscreen and mass storage device capabilities for image transfer, the DIY-Thermocam V3 can even stream thermal images over USB serial. The software’s already extensive capabilities can be extended even further thanks to open-source, PlatformIO-based firmware. Images are saved to the internal microSD care at a resolution of up to 640×480, with 18 different color schemes. A 2000mAh battery allows 4-6 hours of operation.
