4 years of playing tanks

Good day, dear reader!

Today I want to tell you a funny, not yet finished story of strange coincidences, victories and defeats, joy and confusion. If you are wondering how, perhaps, one of the smallest "smart" (and not just r / y) tanks in the world was created, as in the picture below, as well as what IoT, PHP and Angular have to do with it, I will be glad to explain!

  • Maxim, Andrey and their entire team, who consulted, poked their noses and in every possible way accompanied the development of not only the project, but also me

  • My wife is still a bride, for help and patience.
