Opensource, inexpensive, mobile thermal camera for use in electronics, home inspection, non-contact thermometer, heat distribution and more.
We have created a Node.js module (otc) that supports all available interface calls. On top of that, a demo cross-platform desktop app is in the making! Electron uses node.js' runtime therefore we used the mentioned module to create a simple cross-platform app. It was tested with WIn10 and RPI3 (Raspberrian). OTC is connected to the computer/RPI with a USB 3.1 Type C Female To USB 3.0 Male Connector. The electron app is already available on github.
In the future we are planning to create a module for Python as well, which will support all interface calls.
Next stop: People counter!

Open Thermal Camera went through a slight redesign. The hardware is now unified for both Type-C and MicroUSB version. The housing can accept either of the PCB variants.
(Right: Type-C variant, Left: back view of MicroUSB variant)
With this step the hardware part is coming to an end and we'll start with improving the application side even further.
For easier assembly and consistent results with heat inserts, I took an evening to create a heat insert tool for use with a Ersa soldering iron.
It looks something like this
It's made for M2.5 inserts, which are used in housing for our project.
This helps with much nicer finish as tested on our prototype housing.
While preparing for the upcoming Mini Maker Faire in Italy, Trieste, we've build more prototypes for people to try out and give their opinion on it.
Also if you are around or you consider coming to Mini Maker Faire in Trieste this week 25th and 26th of May, do stop at our booth with number M-94 and give our project a try :)
On to the pictures:
More sensors came from DigiKey.

Yesterday (11-May-2019) we presented our Open Thermal Camera at Mini Maker Faire in Ljubljana. Many were impressed with the project and gave us some interesting use case ideas, such as home insulation inspection, water leakage detection, observation of wildlife etc.

We had a few gadgets with distinct thermal contrast, such as:
We had a great time presenting our project to other makers and DIY enthusiasts =)
Today I've created a repository for Android application on GitHub. There is quite some work to be done on application side but things are working well up to this point. In the following days we'll be working on a use case scenario of inspecting a PCB. Stay tuned!
