Hardware interface information/exchange for MeteorJS + Meteor-Cordova https://github.com/SpaceCapsule/Meteor-Cordova

hardware.js

/**
 * Utility functions to help determine what kind of device you are on,
 * and what it's capabilities are...
 *
 * This is very much a "custom" implementation to my needs, but may help as
 * a starting point for others and perhaps for more generic Hardware
 * information.
 *
 * Current version relies on Meteor-Cordova (the iframe appraoch)
 * https://github.com/SpaceCapsule/Meteor-Cordova
 *
 * Easy to change the "guts" of these methods to handle other interface
 * aproaches.
 *
 * TODO: abstract to support all of them
 *
 * NOTE: some overlap between this and client/lib/cordova.js

Cool didnt know about the blink plugin
