I'm a little lost at step 10
Depends on the load impedance, I'd go for a 220uf, should be plenty if you're using it before an amplifier.
Not true, at higher rpm's a lower pitch is more efficient.
I had a look at the code, it is very bloated, I would suggest you use the emonlib from open energy monitor and instantiate a single object per analog pin you want to monitor. The way to do it in the code provided in the instructable would be to change the following lines:#define NUM_CTS 1#define MAX_CTS 1AND THEN you will need to trace down all the arrays that jmengel declares, and only add a single element to them. It's a very inelegant way to do things though.
