Here I will place information about progress in my M. A. thesis. I have chosen my own topic for this work, because my father wanted to make a small solar system on the roof to use some energy to heat the water. I decided to make the driver for this system and then my topic sounds:

"Solar system with data aquisition module"

Someone can ask me:
Why do you write about it here? It's useless.
Yes. That's true. My electronic knowledge is really small, and I think information here might be useless, but I think that, maybe when I will be retired in the future, I will read it with pleasure and I will recall this good time when I was starting to do something and to realize how stupid I was before :)
