Backpack GPS tracker

Contest Winner

When going on a holiday, vacation or to SPY on your girlfriend having a GPS datalogger in your backpack would be fun and handy... I just got a brilliant idea to turn u LAPTOP bag (+ur laptop) to a PORTABLE GPS data logger, I just feel its really cool to get back home and replay your path, you could also add a open log or and SD MMC card datalogger to make it smaller....

once you get back...u can get the data and play-back u trip on google earth....and see ur self MOVE....check out the video below and see how cool it is...

Sorry for the low quality video...but the path/track animation is very smooth...

Step 1: Required!!


1.GPS chipset with external antenna feature(RPSMA connector) which gives a RS232 output

2.Mountable(Magnetic) GPS antenna

3.USB to Serial converter(prolific will do FTDI also works fine)
   (any other CABLES to make connection)

4.Battery Back(12-9v).

5.LAPTOP(win xp/linux/win7….wat eve…)

6.LAPTOP bag (targus is good)

Step 2: Connections


Connect the USB<-----> Serial Converter to a Serial Wire...
Connect the USB to your LAPTOP and OTHER END to the GPS Receiver
Also Power the GPS with an External Battery as Shown
It is good to tape the UBB port, So that the cable wont come off or there are no loose connections!

Step 3: PC settings!


POWER OPTIONS!!
go to POWER OPTIONS from CONTROL PANEL select ur POWER PROFILE and click CHANGE PLAN SETTINGS
from PUT COMPUTER TO SLEEP select NEVER when ON BATTERY OPTION (refer figure) and SAVE the settings

select DO NOTHING from WHEN I CLOSE THE LID when ON BATTERY option(refer figure) and SAVE the setting
!!DONT FORGET TO SAVE BOTH THE SETTINGS!!

yes u can....u can use a micro.. load at FAT lib on it...interface a SD or MMC card to dump all the data from the UART to a txt file on memory card....u can get all instruction in a PDF file, register as a pro user...

where would i be able to get a gps chipset from? and would there be anyway to load this to a memory card without the use of a laptop or upload in realtime for tracking purposes?
