Whither tCam

A project log for Lepton 3.5 Thermal Imaging Camera

Documenting my experiments with the FLIR Lepton 3.5 thermal imaging camera.

It's crazy sometimes how fast time seems to fly by.  I have been working on tCam for over two years now in fits and starts.  I can see how someone reading these project log entries might suppose it's a dead project.   It isn't but it also isn't where I wish it were.

The good news is that the code is essentially done and the camera works.  Shown above with a streaming display also shown on the iOS mobile app.  I am currently working toward FW 3.0 for tCam-Mini and will include its new functionality in tCam as well and that will be tCam FW 1.0 running on gCore.

In addition I'm working with Group Gets to bring gCore to market as a general purpose ESP32 development board for building GUI-based battery powered gadgets.  The gCore design is done and I even have an Arduino library and a bunch of demos written for it.  I think it's going to be very cool.

The frustrating news is the parts shortage is making it hard to build gCore.  It may end up with a slight redesign to accommodate available parts. 

I am considering pushing the code to github even though it won't be super useful without gCore (or some modification).

Here are a few more pics showing how tCam is easily built using a Revision 4 tCam-Mini and gCore in a laser-cut enclosure.  The jumper on tCam-Mini configures it to use the hardware serial interface to communicate with gCore.  Hopefully there will also be a 3D printed enclosure design.
