Yes, except the 8-pin ICs were free, and the university beaurocracy didn't have to approve it first. I only have 2 weeks or so to finish what I have.
I'm not sure I understand capacitor coupling the anemometer signal. I wish I had a scanner to show my circuit layout for the chip. But I really just want to know about this "level-shift" ordeal. It's something with transistors to literally shift the voltage (0 = -1, 1 = 0, etc) but I can't find it in my books.
