THRmAL Handheld Thermal Viewer (Thermal Handheld Rendering meets Additional Lasers)

thingiverse

THRmAL is a portable, low-resolution thermal viewer that leverages the Panasonic GridEYE thermopile array. This handheld device boasts a color OLED display, semi-modular design, and four lasers that mark the corners of its field of view. Initially created to assess heating uniformity on printer beds, THRmAL also proves useful for examining PC thermal performance, pinpointing hotspots on devices, and various other applications. THRmAL was built using as many parts from my inventory as possible, resulting in suboptimal electronics such as a 5V microcontroller. If you plan to replicate this project, consider substituting the Arduino Nano with a 3.3V microcontroller, removing the level shifter and 3.3V voltage regulator from the design. STEP and Eagle files are available for modifying the entire design to match your specific components. It is recommended that you measure your parts and review the STL files before printing anything, as adjustments may be necessary.
