FBI tracking device

I've always loved James Bond movies. One of the special devices that Q and his team made was a tracking device so Bond could follow Goldfinger or other evil-doers. Well Q must be working for the US Government now because the FBI is doing the same thing today. These warrentless trackings are taking place all over the country as we speak. You may want to take a look under your car some day and see if there's anything odd under there!

Here's a great article on the devices:

Disclaimer: We love the FBI. We've had the opportunity to help them fight crime 
on several occasions. We've helped them with instructions on gaining entry into 
certain devices. We have nothing against them, and we hope they don't come after 
us for sneaking a peek inside their nifty tracker.

Now that we're in the clear, it's teardown time!

We partnered with Wired (http://www.wired.com/dangerroom/) to bring you a peek 
inside an FBI car-tracking device. The device was loaned to us by a person who 
found the device on their car, and is similar to the one Yasir Afifi recently 
found underneath his own vehicle (http://bit.ly/fbi_tracker).

The hand-assembled device is comprised of a GPS unit for receiving the car's 
position, an RF transmitter for relaying your location to the interested 
authority (aka the FBI), and a set of sweet d-cell lithium batteries that power 
the whole enchilada. 

But we didn't stop there, of course. Read on to find out exactly what components 
make this secretive device tick.
