Question 1: what type of current will be created when passing magnets past a coil? AC or DC?
Question 2: What is the best way of storing the electricity generated with a contactless dynamo?
I'm working on a contactless dynamo project for my bicycle, (similar to this project: http://www.instructables.com/id/Contactless-dynamo-powering-bike-safety-lights/) except my concept includes being able to turn on/off the lights at will instead of them receiving power directly from the coil as shown on the link I just shared. I'm attaching some photos for reference.
I was successfully able to get a simple LED to flicker with 6 small neodymium magnets and one 12V ~80 Ohm coil. From what the internet and some friends have mentioned, I would need to convert the AC being induced by the magnets passing by the coil into a battery for a more complex bike lighting system.
My ideas for the bike lighting system are to power a front-facing headlight, a rear-facing brake light, increase luminescence of rear-facing brakelight when I apply pressure to handbrakes, a blinker system sensitive to turns and toggle-able with hand switches. Similar to how a lighting system would work on a scooter or motorcycle.
Any insights into this would be much appreciated!
