GALLERY OF DESIGNS — click a thumbnail for a larger version    Broadcast Stuff
	Since high school, for my own amusement I've drawn pencil sketches of plans, playing with the challenge of working out the geometry.  Here is one category:  broadcast stuff, including a low-ceiling studio, that I imagined constructing with primitive technology.  These days, there are better methods. In the 1960s, broadcasters began using hand-held TV cameras as a more mobile alternative to bulkier traditional cameras.  But the weight of a "hand-held" is actually supported on the cameraman's left shoulder.  While I was still in high school in 1964, I sketched an even smaller camera that would literally be held in the operator's left hand. In my design, the lens is at the top of the front of the camera.  Two partly-silvered mirrors and five prisms separate the light and direct it to the red, green, and blue camera tubes, which are mounted vertically below the prism assembly.  (An extra lens is needed at 9 because the light path to that tube is longer.)  A small electronic viewfinder is also mounted on the top of the camera, along with a pair of tally lights and a zoom lever. (TEXT CONTINUED BELOW) A zoom lens is heavy and bulky and would unbalance this little camera, making it even more difficult to hold.  So I specified a simple fixed-focal-length lens and a "scan-type" zoom, akin to what is now called a digital or electronic zoom, which would unfortunately have compromised the image quality.  To zoom in, the camera would be electronically adjusted to scan a smaller portion of the image on its tubes. Nowadays, of course, tubes have been replaced by solid-state sensors, and cameras can be much smaller than this.
