As the days get shorter for my commute I dreaded another season worrying about charging batteries.  I took the dyno plunge and wired up the commuter.  Have not rode in the dark yet (will get to that tonight) but the ride in was uneventful and the hub is smooth.

OK, so I got around to testing it!  It is way brighter than I anticipated.  The photos at Peter White cycles web site show it well.
