White Label Hand Crank Dynamo

Here’s a great gadget that will allow you to add Greenpower to any
of your projects. This is a hand crank dynamo, pre-assembled but
easily modified to be retro-fitted to existing equipment or added
to new projects. Crank the handle and the specially designed gear
set will operate the motor and produce a DC voltage which can be
used for a variety of low current uses (charging batteries, lights
etc). Crank slowly and the voltage is low, crank harder and the
voltage is higher. Made from plastic so it is easy to re-work to
fit your projects.
