I made this drawing when I was
about 12 years old. The parts of the machine reflect the
technology of the era. Note the analog dials, magnetic tape reels,
and oscilloscope screens. When I drew the picture, there were no
cell phones, CDs, video recording, cable TV, personal computers,
or pocket calculators.
Much of this drawing was inspired by what I saw in my favorite
museum at the time, the Griffith Observatory
planetarium and science hall, located on Mount Hollywood in Los
Angeles. It had many fascinating exhibits. I remember in
particular the Foucault pendulum, camera obscura, fluorescent
mineral exhibit, the sound-triggered oscilloscope, seismograph,
and Tesla coil. The Tesla coil is thick coil of wire piled into a
huge cone, which emits noisy lighting and causes nearby
unconnected fluorescent light bulbs to light up.
