Woodcrafted

The intentions behind this Project were to be a science demonstration, to collect data on the performance of homemade PM alternators, to show how easy it is to build a windmill from scratch without metal-working tools ... and to be a bit silly. So imagine our surprise when it made LOTS of useful battery charging power! The more cynical folks around here (me) are calling it the "Wood 403"

Shows what can be done with wood, epoxy, a round shaft, magnets, and wire. Shows some of the basics of the alternator principle. Not recommended for a long lasting windmill but could be modified toward that direction. Using ball bearings instead of a wood bushing would help a lot.
