  Hi Guys I just got my Puck unit today and have a try on it.
  I am a designer so sorry for my dirty code.

  Basically what I want to test is:

  1. single click, double click, triple click (or more)
     
  2. media control HID ( play/stop/next/prev/volume)
     
  3. light on!
     
  4. Magnet
     
     

  The magnet part is the most hardest part for me .. and even now not really working good,
  so please! enhance that and let me know!
  After I play a while on my mac... then I connected it to my iPhone .. OMG its working too! miracle!

  • special thanks @gomako for the rotating code!
    
    

  How to play//

  1. Single tap to send the Play/Pause singnal (suppose to launch the default player!)
     
  2. Double tap for next song
     
  3. Triple tap for Prev song
     

  4. Press, hold and rotate for volume contorl

  Thanks! ... Sadly...I still don't get it, should I just ..

  var r = Puck.mag();
  var angleToTheNorth = getheading(r.x,r.y,r.x);

  seems not like this ?

  Hi all!
  I want to make a volume control by rotation the Puckjs.
  basically I want to get the angle value change once use press and rotate the Puck,
  if the value large than a preset value, I call a volume up and then
  reset and wait for another value pass.. I also need to know every time user rotate left or right..

  I got xyz from the magnet sensor but I am not sure what to do next.
  I did some search on the sin cos tan.. its quite complicate for me..

  any hints ? thanks!!!
