I've been fascinated by electronics and electrical machinery of all sorts ever since I was old enough to wield a screwdriver. I was the kid who took TVs apart when all the other kids were out playing football, or getting laid, or what is crudely known as "Getting a life" :P But, like Jim Williams once said, if you're a dog, you're going to sniff trees. I decided to follow electronic engineering as a career, and for the past 7 years or so, I've been making a living as a circuit designer and embedded programmer.

As regards hobby projects, I've just been through a heavy phase of Tesla coil building: I think I kind of got obsessed by the power of them :-) You can read about my experiments in the Tesla coil pages. Before that, I experimented with hi-fi and guitar amps. I hope to go back to some more audio projects, but not till I've finished that last giant Tesla coil :)

I also hold a ham radio licence and have been playing around more with RF lately.

I'm not entirely sure whether I have "got a life" yet. I only have two oscilloscopes, if that helps ;-)
