Electric generator from a bicycle tire

I've gotten the notion to make a simple but effecient electrical generator
from a bycle tire. I truely have no use in mind, but perhaps I'd like to
hook the generator up to some LEDS and make it do pretty things when I give
the wheel a spin. My entire body of electrical knowledge comes from a high
school class I took over twenty years ago. I think I remember the basics (
permanent magnent passing over a copper coil) but that is it. Can anyone
here recommend places I might start to read? Again this is for fun but it
would be nice if the thing worked! If I remeber right almost every thing
would affect how it generates, the size of the wire, the number of twists,
the strength of the magnet, etc. etc. Anyway if I could get some
suggestions on a few articles to read I'd be greatful.

 

I just made one with my daughter not to long ago for a science
project.
I quickly discovered it was a pain making coils of wires so took apart
two 24VAC relays and used those coils.
We also had an old 12" fan lying around and disassembled it. The idea
was to use the shaft and armature of the fan. I drilled 4 holes in
the armature to accomadate some neodymium button magnets that I got
from Allelectronics.com.
The whole thing was mounted using some L brackets to hold up shelves
to a 2X4 .
The coils were connected in series and then to LED's .
It worked great!
Hope this helps?

Don't post binaries (files) to a non-binaries group.

Binaries groups start with alt.binaries.*, generally...

Ummm, Ok, but I didn't attach any binaries?

Sorry, there's a PDF attached as a response, and I assumed it was from
you (like you were showing us what you had so far)... duh... different
names.

Please accept my apologies

Another good reason for not attaching binaries in a non-binaries group
is that many news-servers notice the "non-binaries" flag on the group
and just throw away the attachment.

I use Freeserve, one of the UK's biggest ISPs, with newsgroup coverage
many US users would envy, from what I hear. But if the group says
it's non-binaries, Freeserve believes it. I couldn't read the
attachment even if I wanted to
