This is a project  to   display and save your location during activities.   There are a lot of 

fancy GPS watches that can do it all , but for those who want to experiment and be creative , this is the way to go.

The main parts are     Atmel Mega 128  cpu   - Gps unit  ,  1.3" Oled , uSD card  , 4 buttons for user interface  , usb charge  , usb serial interface for bootload , pads for first ISP pgm ,  temperature sensor  , ext gps ant socket ,  vibrator motor  , buzzer   .

This board is ver 2  for a 1.3 " Oled display   , the 0.96 " is just too small for active  outside use.     The firmawre is all in BASCOM  AVR  and I have used ver 1 now for about 2 years  and tracked a lot of races with it. 

Pcb and compoment is quite tight and need a sober stable hand for soldering!

GPS  data is saved as a GPX file   and  can then be uploaded to STRAVA for diplay etc.
