Generator

thingiverse

I have never built a functioning generator yet - so aiming to finish this one and charge my phone via hand crank. My design started from what magnets i had available - 22mm x 15mm Everything else took shape from there. Still busy with this, will update as I go along inspiration from http://www.thingiverse.com/thing:1766551 2016-11-07 -- I have got this working and I am getting just over 9v spinning the shaft with my fingers. which i dont think is too bad. I dont have anything else to compare this too, this is the first generator I have made that produces electricity. Things i did not take into account: The Wiring - wires everywhere. this is something you need to plan for. Geometry of the rotor & Stator - my rotor has 4 magents and stator 6 coils. at the moment only one set (opposite coils "Fire" at the same time) I have wired the set of coils (opposite ones) in series and then to a bridge rectifier. then connected these three sets in series with a capacitor to smooth out the voltage drops. works awesome - now im at a point where i want to charge my phone but more electronics and circuitry are needed. 2016-11-11 I have uploaded a picture of the circuit i am not sure on how to proceed from here. should i connect a buck/boost converter to achieve a stable output? is this the best circuit ?? if you have any ideas / comments let me know.
