Adafruit's DIY Arduino Thermal Camera is an intermediate level project for makers that involves 3D printing and the assembly of electronics.
The 3D-printed camera boasts a design that reminds of vintage cameras and it is one that can be customized easily based on one's color preferences. On the inside, a few electronics are required and some programming must be completed for the thermal sensor and screen to function properly.
Once the DIY camera project has been fully assembled, it can be used for a wide range of purposes. Thermal cameras are ideal for looking at heating and cooling systems, including ones within the home or a car. While the thermal camera can be used for the sake of fun, it also has the potential to be used to observe heating and cooling issues.
