Thanks for stopping by, Steve. I've followed your projects for a while, I remember reading the article in an old Popular Science (your article was in 1984, someone gave me a stack of magazines and I probably read it in 1989). Reading about the BEHEMOTH was definitely part of the reason I developed an interest in electronics and other technical subjects.
The Arduino community is great, and I have no doubt that you'll be able to get on your feet quickly due to your previous experience. See you around!
