It’s led me to push really hard to switch to Micro-Epsilon. My guess is they only really care about their military cash-cow contracts and maybe high-volume commercial customers, and my employer usually only buys a couple per year so we don’t qualify. Unfortunately, because my solution worked, we’ve continued to use these FLIR cameras since. I ended up burning many dozens of hours reverse engineering things that should have taken just a few hours. Any questions took weeks of struggling to get an answer. One of my first tasks at my current job was to integrate a FLIR thermal camera with an existing machine. Posted in hardware Tagged diy flir camera, Flir lepton, tcam-mini Post navigationįLIR support is atrocious. Along with tweaking the ESP32 firmware, there is still a lot that can be done with the TCam-Mini, but it sure looks like a fun project to tinker with if one is into Leptons. For this he repurposed an old in-ear thermometer calibration device.
Recently has also begun to further characterize these Lepton sensors, in order to see whether their accuracy can be improved from the rated +/- 5-10 ☌. Being able to load the radiometric data directly into a desktop application for processing makes it a closer match to the professional thermal cameras which states that he’d like to get as close to in terms of features as possible.
Lepton thermal camera portable#
Compared to the aforementioned FLIR One Pro, there’s a definite benefit in having a more portable unit that is not reliant on a smartphone and accompanying FLIR app. Not cheap, but quite a steal relative to e.g.
The project is available on GitHub, as well as as a GroupGets crowd-funding campaign, where $50 gets one a TCam-Mini board, minus the $199 Lepton 3.5 sensor.
Lepton thermal camera software#
Using the 160×120 pixel FLIR Lepton 3.5 thermal sensor, and combining it with a custom PCB and ESP32 module for wireless, he created a wireless thermal camera called the TCam-Mini along with accompanying software that can display the radiometric data. While the ultimate goal is to create a stand-alone solution, with its own screen, storage and processing, the TCam-Mini is an interesting platform. With how expensive thermal cameras are, why not build your own? This is the goal with which set out a while ago, covering the project in great detail.
