Generator

thingiverse

I'm currently working on a functioning generator, aiming to finish it and charge my phone via hand crank. My design started from the magnets I had available, which were 22mm x 15mm in size. Everything else took shape from there. Still busy with this project, will update as I go along. Inspiration was drawn from http://www.thingiverse.com/thing:1766551. 2016-11-07 - This generator is now working and producing just over 9v when spinning the shaft with my fingers, which I think isn't too bad considering it's the first generator I've made that produces electricity. Things I didn't take into account include: The Wiring - wires are everywhere and need to be planned for. Geometry of the rotor & Stator - my rotor has 4 magnets and stator 6 coils. Currently, only one set (opposite coils "Fire" at the same time) is working. I've wired the set of coils (opposite ones) in series and then to a bridge rectifier, followed by connecting these three sets in series with a capacitor to smooth out voltage drops. It works great now, but I'm at a point where I want to charge my phone - more electronics and circuitry are needed. 2016-11-11 I've uploaded a picture of the circuit and I'm unsure about how to proceed from here. Should I connect a buck/boost converter to achieve a stable output? Is this the best circuit possible? If you have any ideas or comments, let me know.
