Since the days of Alan Turing, the promise of a digital computer has been that of a universal machine, one that can be a word processor one minute and a robot brain the next. So why are radios, a technology even older than computers, still designed stubbornly to do one thing–like 3G, Wifi, FM, or GPS–for their entire lives?
In fact, the era of the single-purpose radio is over, says Michael Ossmann, the founder of an Evergreen, Colorado company called Great Scott Gadgets. And he believes he’s built the one cheap, hacker-friendly radio to rule them all.
At the ToorCon hacker conference in San Diego Saturday, Ossmann and his research partner Jared Boone plan to unveil a beta version of the HackRF Jawbreaker, the latest model of the wireless Swiss-army knife tools known as “software-defined radios.” Like any software-defined radio, the HackRF can shift between different frequencies as easily as a computer switches between applications–It can both read and transmit signals from 100 megaherz to 6 gigaherz, including frequencies as low as the range used by FM radio up to the gigaherz frequencies used by Wifi or experimental wireless protocols for cars communicating in traffic. In between those bookends lies everything from police radio to cellular signals from AT&T and Verizon to garage door openers–all signals that HackRF can instantaneously intercept or reproduce. And at Ossmann’s target price of $300, the versatile, open-source devices would cost less than half as much as currently existing software-defined radios with the same capabilities.
