Scoping the Shimano Nexus alternator hub
I have a four 3W Cree LED system (two in the front, two in the rear) installed on my Linus. It has a Shimano Nexus HB-NX50 6 volt, 3 watt alternator hub that seems like it should be useful for running other things on the bike. Unloaded it outputs up to ~20 V AC. The LEDs are used directly across the alternator output since it doesn't make sense to use additional diodes to rectify the signal.
