We’re starting to document Sam’s generator-hub-powered bike light. I’ve been using an earlier version for the past few years and this new design is ah-mazing. We’d like to get folks together for a build-night if you’d like to make your own. The total cost is about $25 per light, which is crazy cheap for a very *bright*, indestructible light that you never have to charge or forget at home. Keep posted for build-night details.
