Bike Light 2011

Just another bike light! Generator Light

This one is encapsolated in Epoxy....  I'll update this Instructable on how well it functions... and with Phase 2 following soon.

Dynamo Hub! There are several to choose from. This is a midrange model Shimano DH 3N71. What's great is they're all 6Volt 3Watt.

Step 1 Parts

Need to Bridge the Generator HUB AC power to DC using diodes... this is covered in on my previous light project as well as these geniuses:

 There are quite a few circuits and great LED tutorials on Instructables. Just check out some resources to get your bearings.

As the front wheel turns it creates alternating current (AC) power. The 'bridge' is a rectifier that converts the AC dynamo power to DC power. The bridge is made up of qty(4) 1N5818 diodes.
