## What it is
DIY-Thermocam is an open-source, self-assembly thermal imaging camera based on the FLIR Lepton sensor and a Teensy 4.1 microcontroller, with Arduino-compatible C/C++ firmware. It includes a companion ecosystem of desktop software for live viewing, thermal data analysis, and video conversion.

## Use cases
- build my own thermal imaging camera at low cost
- find heat leaks in building insulation
- inspect electrical or mechanical components for hotspots
- detect persons or animals with infrared
- mount a thermal camera on a drone for time-lapse recording
- stream live thermal images to a PC over USB serial

## When to choose
- you want an affordable, customizable, open-source alternative to commercial thermal cameras like the FLIR E6
- you enjoy self-assembly projects and want to modify firmware or hardware
- you need raw thermal data access for analysis or education

## When to avoid
- you need a ready-made, calibrated professional-grade thermal camera out of the box
- you require high frame rates or resolutions beyond 160x120
- you have no interest in soldering or assembling hardware yourself

## Facets
- artifact type: application
- maturity: active
- function: embedded, image-processing, developer-tools
- domain: hardware, computer-vision, image-processing, iot
- platform: embedded, cross-platform, windows, cli
- tags: thermal-camera, flir-lepton, arduino, teensy, open-source-hardware, lwir, firmware, diy-electronics
