iPhone HiJacked

Fed up of how every accessory for your iPad/Phone/Pod has to be especially made to fit the port at the base, a deliberately obstructive piece of design that means any peripheral will be expensive and only useful for Apple products, further tying you into their closed off little world – it’s a gadget apartheid they’re setting up here, somebody call the Feds!

Anyway, one group of young whippersnappers from the University of Michigan's Electrical Engineering and Computer Science Department have designed a device that they call the ‘HiJack’, which is a hardware and software platform that plugs into your earphone jack and communicates with your non-Apple sanctioned peripheral. How does it do this? Well according to Arstechnica: ‘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.’ Clear as mud, right? Just watch the video below, then.
