Martin Brennan, who designed JB7, has a degree in Physics from Cambridge University
He has worked with Sir Clive Sinclair and Sir Alan Sugar.
Martin designed over 20 silicon chips in his career. He was a pioneer in the computer games industry - he played a central role in the design of the Konix Multi System and co-designed the Atari Jaguar - the worlds first 64 bit games computer.
Ever since CDs were invented Martin wanted a CD player that would hold his entire CD collection.
He wanted something as simple to use as a light switch but at the same time something that would let him find a particular track without leaving the armchair - and he wanted something that could rattle the windows when he was in the mood.
