I found your life story very interesting, I wish I had your computer talents. I invent things, but I'm afraid that when I was in high school, the yellow tape with holes punched in it, that told the computer what to do, was not all that exciting to me. Your desires in the self sufficient area are much like my own, and plan to be off the grid in the near future. Would like to talk with you more. You might want to go to my last project and in the comments section, I answered a guys question, and gave a long posting on stone work. I included at the bottom of that, 2 links to an invention I came up with about 2 years ago. They're videos on youtube. Talk with you later.
