Arduino + GPS + LEDs = Find home detector

Hi, The Find home detector is a device to show me the way home by indicating the direction with a light. It uses a LilyPad, GPS, compass and some LEDs. Using the GPS to get a position and then calculate the direction to the location of my home. The compass is then used to get my heading so it is possible to indicate the direction I should travel.

Great idea!

Well done,

I love it, that's wonderful!

Would have made finding my hostel one night in Berlin a lot easier, that's for sure.

Plus seeing the look on people's faces as I walked by with that would have been wonderful :D

That looks pretty cool. Maybe even add a "waypoint system", where you can push a button to set a waypoint and it can guide you through your previously set waypoints.

this is an awesome project! i can see many uses for the core of this. great work.

quick question:

why is there a 50 unit gap? is this to avoid flickering between two directions?

 northOn = 3350 < directionToDestination || directionToDestination < 250;
  northeastOn = 200 < directionToDestination && directionToDestination < 700;
  eastOn = 650 < directionToDestination && directionToDestination < 1150;
  southeastOn = 1100 < directionToDestination && directionToDestination < 1900;
  southwestOn = 1700 < directionToDestination && directionToDestination < 2500;
  westOn = 2450 < directionToDestination && directionToDestination < 2950;
  northwestOn = 2900 < directionToDestination && directionToDestination < 3350;
