Okay, I'm *very* impressed by the skill and knowledge people have here. But knowing is one thing, understanding is a second, and actually building is a huge third thing. I have ver little experience in building these kind of things. So it will take a long time for me to put this together.

Yes, that would be incredibly nice. Then I just need to find the parts. Suddenly everything took a big giant leap from scrapheap sensor to hitech counterbased sensor. But as long as I good something pretty accurate within a reasonable budget and complexity I'm happy.
