Bugle Call into Megaphone Gets ‘em Up in the Morning (Mar, 1941)

Bugle Call into Megaphone Gets ‘em Up in the Morning

Reveille sounds painfully loud these days to the boys in camp at Fort Jackson, S. C. When the bugler sounds “I can’t get ‘em up in the morning” he steps to a huge megaphone that blasts his notes throughout the camp. Mess call, he finds, does not require so much artificial amplification.

Every home game —day or night — played by the New York Giants, Yankees and Brooklyn Dodgers will be seen over television this season!

Owning a television receiver in the New York area will be like having a season pass for all three ball clubs. And in other cities, preparations for the future telecasting of baseball are being made.

Mystery Cell Aids Television (Aug, 1930)

Mystery Cell Aids Television

Remarkable demonstration in theater shows big improvement in seeing and hearing by radio. New process used to aid planes blinded by fog.

By ROBERT E. MARTIN

TWO remarkable developments recently revived public interest in television, and brought the dream of practical transmission and reception of “images on the air” a step nearer realization.

In a dramatic demonstration at Schenectady, N. Y., a few weeks ago, Dr. E. F. W. Alexanderson, consulting engineer of the General Electric Company, projected six-foot images bright enough to be seen by a large gathering. Before that, the best television image had been only a few inches square and had been produced by the feeble flickering of a neon tube.

VIOLIN HOOKED TO RADIO SET

Stringed instruments without sounding boards, including violins, cellos, guitars, and ukuleles, have been devised by an eastern violin maker. Vibrations of the strings pass through the bridge to a magnetic pickup, resembling a microphone, that converts them into electric currents. These are amplified to operate a loudspeaker. At home the instruments may be plugged directly into the family radio. One of the new violins is illustrated above.

Movie Camera Is Also Projector
FILMS may be projected as well as taken with a midget home movie camera marketed recently for amateur use. A tiny but powerful electric motor operated by four flashlight cells drives the film during exposure, and supplies power for the projector bulb. The film used is 9-1/2 mm. wide, but has a picture area about the same as that of 16 mm. film, since perforations are in the center between the frames. The camera has a fast f 2.5 lens, giving usually clear pictures.

Strange PERILS of Making MOVIES Beneath the Sea (Sep, 1933)

Strange PERILS of Making MOVIES Beneath the Sea

Hollywood’s most intrepid cameraman relates startling adventures he has encountered making undersea movies which chill your blood.

by HOMER SCOTT - Pioneer Underwater Cameraman

IN 14 years I probably have gazed into the cold eyes of more curious fish and looked on the bodies of more actors and actresses beneath the sea than any other man. From the shores of Southern California to the rocky coast of the Socorro islands, far south in the Pacific, and even off the shores of New Zealand I have descended many times in one of my half-bells, my legs dangling puppet-like in the cold water, to photograph dramas that sometimes thrilled me more than were the audiences that viewed the results on the screen. ] When the editors of Modern Mechanix and Inventions asked me to write of the thrills and tell you how these scenes are filmed, I said to myself, “Gosh, there’s nothing very interesting about undersea picture-taking.”
