The system uses a 22kHz audio signal, which is converted into 7.4mW of power at 47 percent efficiency. That power runs a TI MSP430 microcontroller as well as any attached electronics, and allows the HiJack to communicate with an iOS application. The components to build a HiJack cost as little as $2.34 in significant quantities." -- Jan Quote Link to comment Share on other sites More sharing options...
