This project is not dead, but I didn't had time for it yet. I wanted to work on other "smaller" projects first... But now I'm ready to work à little bit on it. 

I'm still not sure of the power source I will use, probably a pair of drone batteries. 

What is sure is that I will make a prototype using standard modules from aliexpress 1st, and then I will create a dedicated pcb with everything required on it. And it will became my most advanced project so far.
