dynamo (alternator)- energy module

Building a homemade alternator that pumps out 10 volts at 150 milliamps is an incredible feeling. I drew inspiration from my previous projects, like the winder and coil customizer, to make this one. Here are some resources I used to bring this project to life: * This video on YouTube showed me exactly how it's done: http://www.youtube.com/watch?v=GNR8xGPmUM0 * My trusty winder came in handy: http://www.thingiverse.com/thing:100648 * And my coil customizer was a lifesaver: http://www.thingiverse.com/thing:73915 Now, let's talk about the materials I used: * A copper wire coil with a diameter of 0.018 inches is the heart of this alternator. * Two bearings, one with an outer diameter of 4.5 mm and an inner diameter of 13 mm, keep everything running smoothly. * The central magnet measures 30 mm in length and 10 mm in width, while the four smaller magnets that serve as terminals are each 25 mm long and 3 mm wide. * Two even smaller magnets, about 15% the size of the others, act as the terminal ends.
