Raymond Boswel is an electronic engineer from South Africa. He works as a systems engineer for a telecommunications company. Although the powers that be don't condone playing around with single-board computers during office hours, he enjoys fiddling with them during his free time. So far, he's used his Beagle for convolutional, frequency-response modeling to spice up his guitar amplifier, automation, and time-lapse photography. Having read this book, he might just turn his attention to espionage. Enjoy!
