Will try to put some pictures up later today. Not sure how to do it though.

The hub is a Shimano DH-3N80. I bought it for $110 through Amazon. I could have saved $30 by going with the earlier model, but the aesthetics bothered me (shallow, I know). The whole project...hub, wheel and lights cost me about $450. Pretty steep for bike lights, but cheaper than some other hobbies.
