Yes, I have managed to reinvent the wheel but I hadn't seen anything like this done before so here it is. This project is not quite finished, I still have to put it on a loop for a chain and figure out where to put the battery as I think that it would look good incorporated as part of the necklace. The I used was found on this, http://www.emanator.demon.co.uk/bigclive/joule.htm , site. It is actually a fairly bright light but it was somewhat washed out by the sun. The loop on the back is just excess wire and will be cut off as soon as I further finalize the design. I hope you enjoy!!
PS. I figured I would add it to the green living contest as it uses almost dead batteries until they are totally drained.
