A note on the flow sensor:
The one I mentioned earlier about using--they wanted over $100 for the little thing!
So I found anther one by SeedStudio for less than $10.
I won't know for sure without testing it, but I'm pretty sure the pulses for 1/10 of a 6 oz cup will be 80-120. That being the case I could get by with the 4024 ripple counter, a divide by 128 chip. That would mean a lot less "stuff", especially if I have to use the inverters. (I reckon I do, I just don't understand why yet...)
