gCore is going to be available through a campaign at Group Gets.  This means tCam can also finally become a reality for anyone who would like to make one.  Finally.  It has felt, at times, that I'd never get to this point.

There's a dedicated gCore github repository.  

And I moved all the ESP32 thermal imaging stuff (tCam-Mini, apps, etc) to its own github repository so that people who are interested only in that don't have to download everything else I did with the Lepton.  The tCam firmware has been uploaded there as well as instructions for use and the enclosure designs.  The firmware binaries which must be loaded onto gCore and the enclosure designs can also be directly downloaded from my website.

I realize that gCore might seem a bit pricey at the moment.  Neither I or Group Gets is making much money on this campaign.  It's really a factor of the parts cost (higher than some dev boards because gCore has a lot of high end features, and those take extra silicon), the manufacturing cost as Group Gets is building the boards with a USA contract manufacturer and the initial low volume of only 100 boards.  Even so I think it allows building a full feature, open-source thermal imaging camera for a reasonable price.  Over time I am working to bring this price down.  That will be discussed on the gCore project page.
