How do I build a faraday /kinetic battery with 2 coil wraps in series for added voltage?

I have seen a few projects on building a faraday battery for powering projects, but there is nothing on how to build one from scratch. There is no info how to determine output, choose the proper magnet, etc. I have also heard that you can build one with multiple coil sectors in series for a higher max output.

did you see the dice instructable?

the more wrapped wire the more power
the stronger the magnet, the more power

no-one really does calculations on the proper size and such....
the just 'wing it' guesstimate

use a single coil, it's easier to wire
