Teardown of a FBI tracking device found. Whats interesting to me is the “lithium-thionyl chloride” Batteries inside this device. It may be a low voltage 3.7volts but they last for oh… ten to twenty years!!! Check out the breakdown over at ifixit.
The device is similar to the one Yasir Afifi found underneath his car. If you’re curious where this one came from, Wired has posted a writeup about Karen Thomas, the woman who found this tracker under her car. They’ve also posted a video of Kyle doing the teardown.The device comprises 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 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
