Parents looking to
stalk their own children
keep a watchful eye on the kids, but not interested in logging onto a website every five minutes to monitor Junior's whereabouts, can now ditch the live feed in favor of a product that lets them record their youngster's movements for later perusal. E-tailer Spark Fun Electronics has started offering a complete kit containing a GPS module, battery pack, embedded antenna, and most importantly, an SD-capable datalogger board that can capture up to 440 hours of coordinate data on a 256MB card, and display the resulting map on Google Earth. That's right, mom and dad, instead or paying for one of those commercial cellphone tracking services
, simply sewing the Lassen iQ FAT16 Datalogger
kit into a child's letter jacket or hiding it in their car will give you all the Big Brother-esque information you desire (including speed, for parents of lead-footed teens), and on your own time to boot. Showing your kids that extra little bit of overprotective love will set you back $140.
