My House

I love to work on my house and automate as much stuff as I can. We build our house in 2020 during the Covid Pandemic and since then I am working on it. I love to work with my hands and to see the progress. I still have a lot of projects, at the moment it is my Shed. My last projects were the irrigation system. I learned to drive an excavator during my Projects, it is still fun to work with it. The best thing on doing stuff with the own hands is to have an excuse to buy new tools.
