I built a module powered by left audio channel of headset of smart phone. I used voltage multiplier circuit to amplified low voltage from phone and voltage regulator to stabilize 3.0V threshold to supply electronic devices. Beside I built firmware on MSP430F1611 to encode and decode UART data stream into Manchester code and sent to smartphone.
The module is powered and communicate with smartphone

I designed a system to determine coordinates of the object based on GPS positioning technology and network GSM/GPS using SIM908 module. The system is mounted on the object to track and monitor. User call or send message to the system. It will read the message content to determine control commands. The system will acquire GPS signal and send its coordinates to user. User can display the coordinates of the object on the digital map to see the location of the object.
