| My interest in electronics began at age 10 when my father connected a microphone to an old valve radio and carried it upstairs. We could hear him talking to us through the radio loudspeaker! When he was out of the house, I "borrowed" the microphone and connected it to a loudspeaker and a 12 volt AC transformer. The loudspeaker hummed loudly and the hum was modulated when I spoke into the microphone. This was thrilling. I sounded like a Dalek! I got a couple of large cardboard boxes and constructed my own "Dalek". I crawled inside and thrust a sink plunger out of a hole in the box. Armed with the microphone, speaker, transformer and a long, trailing mains cable, I shuffled up the hallway and frightened my sister. This was power indeed! After that, there was no turning back. I built crystal radios, transistor radios, valve radios, transistor tester, electric guitar, guitar amplifier, waa-waa pedal, oscillators, flashing lights... When my father became bored with his hobby, I took over his project which was the conversion of an ex-army "indicator unit" into an oscilloscope.
