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)
5.LAPTOP(win xp/linux/win7….wat eve…)
6.LAPTOP bag (targus is good)
