bike light generator -[ white wire - battery lighting ]

[npk1977]

Ok, well, i'm hoping to install my motor this weekend. (if it comes.) I'll play around and tell you my results.

I'll try a simple diode bridge -> cap -> 6v/3w lightbulb system. hopefully that produces enough light. if not, then we'll need to add more parts and do an LED thing.

if you're really anxious to get going, pm me, i can give you some pointers. BTW, the basic principle of what I'm talking about is here:

GREAT -

That's what I am talking about -

And, yes, a cap "stores" much like a battery.

Keep up the good work, guys !!!!!!

dr_clabo,

Right, it sounds as if we're all interested in a solution, so i imagine one is only a few weeks away I just want to point out that though a cap stores much like a battery, it is not interchangable in any way, and in the circuit I described, serves a completly different purpose. I only mention this because on reading your comment, I might have thought they were interchangable.

Here's a nice description of a diode bridge:
http://en.wikipedia.org/wiki/Diode_bridge PAy attention to the diagrams on the right hand side that show how an AC signal changes to a bunch of bumps.

And then look at this diagram:
http://en.wikipedia.org/wiki/Reservoir_capacitor that shows how a filtering capacitor would work.

 

[just for kicks]

Oh if only there was enough room in there for a second coil just for the lights.

Well, there's this:

Probably the most elegant solution. It produces exactly the same output, 6V 0.5A as the CDI (I think, not yet tested.) But as a result, if this CDI system is good, in principle, you could buy one of the lights from the site listed above!

NPK, I tried one of those little sidewall generaters and of course once you hit 37 MPH it blows all the lights out.
I wonder if these hub generaters have a wider range when used with motors.

Doc -

I'm not able to comment on the sidewall generators. however, if that's a common problem for you, there is a simple circuit you could build to deal with it

Rest of us -

I'm going to get my bike next week, so I'll take a look at the light next weekend

take care

All ya'll keep us posted until we can make something do-able.
Thanks for all the efforts.
