Alex over at Tinkerlog has hacked together the coolest E-goodie I’ve seen in a while. A GSM powered GPS mobile tracker. Yeah I know, you can do it with your $1000 Nokia N95, well no you can’t….you see this little guy actually sends out SMS messages (over GSM) with it’s current location and since Alex has a AVR ATmega8 controller in there you can probably do some other neat hacks as well. All this for about $550, not bad. Detailed instruction/parts list to build your own are on his site.
