Mike Cook has been developing electronic devices since the 1960s, when he was still in high school. He has authored over 300 computing and electronics articles in the pages of computer magazines for the past 20 years, primarily for The Micro User and Acorn Computing. He is a former Lecturer in Physics at Manchester Metropolitan University. He earned a series of proper positions after leaving the University after 21 years when the Physics department went down, where he built digital TV set top boxes and access control systems. He spends his days surrounded by wires, exhibiting at Maker Fairs, and patrolling the Arduino forum as Grumpy Mike, now that he's retired and freelancing. He co-wrote three Wiley books about the Raspberry Pi: Raspberry Pi For Dummies, First and Second Editions (with Sean McManus); Raspberry Pi Projects (with Andrew Robison); and Raspberry Pi Projects for Dummies (with Jonathan Evans). He also writes a monthly section for The MagPi, the Raspberry Pi Foundation's online and print magazine.
