In Vegas this week! Last week, I was able to use one rectifier in this circuit to drive 1 LED. I ASSUME with two FBR, I could generate two times of power but maybe two times torque needed to generate power as well?
Questions to Jeff:
Why 2 rectifier? Pros and Cons?
How to measure and calculate how much RPM I needed to generate a given amount of power?
Besides oscilloscope (I have no access of currently), How do I measure current and voltage? The readings of voltage that I get from the FBR output is very unsteadily. Maybe I should add capacitor to average it out?
How to limit voltage generated ? I mean if I generate 12v to 5v LED CONSTANTLY, pretty sure it will blow up at some point?? DC to DC step down module seems not efficient enough but need to be tested at some point.
To do list when I get back:
Test capacitor with different capacitance, see how long they last.
Estimate RPM I needed, design gears and LED amount required for my purpose (Ideally 100 or more?)
Research I did this week:
Light source! I could only hind halo shaped fluorescent bulbs! Seems like they don't this kind of shape in LEDs. After some research in generating 110v AC on youtube, I realize it might not be practical at all to power this monster :(
Therefore, I found this light filament:
These are low voltage (3V each, when you put them in series, the voltage rises correspondingly. For instance: 2 filaments would require 6V) and seems very forgiving. I might add a current limit resistor as recommended.
For now, I don't think I have time for diffusion, but will definitely add to it in the future.
That's it for this week!
