Open Metal Detector Project

This is a project started to make a metal detector. I'm using arduino and electronic components from this page: http://hackaday.com/2013/07/25/build-your-own-metal-detector/
I have designed the 3D printable parts. I'm hoping this will gain contributors and ideas so that this project can rival the expensive commercial metal detectors. As of this writing there is a long way to go.

The project is hosted at https://solar1.net/drupal/metal_detector
