ok thanks -- this sounds familiar to what i've read on cycling forums. I was hoping to avoid bridge rectifiers, etc (in other words I'm lazy) but I'll have to give it a shot. thanks for the reply!

I decided too buy a dynohub locally, after viewing this video, and I own several cateyes. So now how do would i hook the two up? as easy as one wire to the + and one to the - ? i tried to look it up online to no avail. anyhelp is appreciated. this will be an awesome bike project.

Inspirational video (really!). It shows how a low output Sturmey dynohub can produse a lot of light if it's hooked up to one of those new LED lights. My question is this: the LEDs seem to require only a very small current to work. Is the dynohub perhaps feeding the LED with too much power?
I'd like someone to answer this question ('coz I don't know about electrics!)

Just got mine last week 3/05/2008. Had to order it. Cost was $149.00.

Hi,
You will have to rectify the AC from the dynohub to DC using a bridge rectifier, they're cheap enough, a simple voltage regulator may be used to protect from over voltage - It could be as simple as using a zenner diode, plenty of info online on both of these components.

Plenty on eBay my friend - mostly found in the U.K
You might find one in the U.S
