Pedal-Powered Brake Lights Progress: change in direction

Talking to Alex, from the recyclelight.me project, was immensely helpful. We brainstormed ideas on how to generate power and activate a switch on the brakes. He was encouraging, but also felt that power generation wasn’t necessary for the project and asked me to think about using batteries instead.

I’d rather not, but doing both switching on the light and generating powere were going to be more difficult than I thought.  So my new idea is to constantly generate power from the pedaling motion of the bike, and use that power  to power an Arduino to which I can hook up sensors, switches and lights. It’ll be a smart bike.

I’m using this tutorial as a basis for creating the generator:

I will need to figure out how to regulate the power for the arduino.
