Welcome to my channel " O MASTROGATOS". Here you may find some electromechanical projects, videos on the construction of tool accessories, the maintenance and repairing of domestic appliances and gardening tools, the construction of simple non commercial electronic devices unknown to the majority of people, as well as applications based on electromagnetism and chemical reactions. In every post, the phenomena are explained by laws of Physics and Chemistry. The final orientation of this channel will be set according to your demands. As for me, I've been tinkering since I was little. I'm a private Surveyor Engineer and I do this as a pastime. I should gladly reply to any of the viewers' questions, as long as I am acquainted with the topics of course!
