I've Garmin eTrex which I bought quite a long time ago (in July 2000 actually when I was in Houston TX) which I don't really use it. Been using it previously for navigation, using a software running on my Palm Vx (which I still have it somewhere in one of my many boxes of old stuff) and used it for geocaching activities when I was in UK (2002-2006). Now, it seems that I could put a good use to it .. by streaming my GPS position to strangers :D
Anyway, to make long story short, I was about to brew my own tracker board but I'm not easily satisfy with thing that is limited to sending out packet. I was looking high and low for a device which could encode and decode th…
