Adventures of Earl Muntz and his TV

A History of TV is not Complete till you Learn about the Adventures of Earl Muntz. How he cut cost to Promote his TV Sets by Incremental Pruning of Parts from a Working unit.

Adventures of Earl Muntz and his TV

What is important to learn from it though, is that we should not overdesign or underdesign. We need to design a cost effective product within customer budget. More Bells and Whistles in yet another Model. A Model to cater to every Purse. And a BareBones model for those who just can barely afford it.

History of Muntzing

Muntz Story

"He took a trip to New York City, checked into the Warwick Hotel and ordered three television sets delivered to his room: an RCA, a Philco and a Dumont. He turned all three televisions to the same channel and began pulling tubes from each one by one. When he pulled one tube too many from a set and the picture went black, he would make a note. Then, he put all the tubes back, changed the channel to another of the four television stations operating in New York City and repeated the test."

Jump into the problem and solve it, See the way a Creative DIY Enthusiast solves an automation problem at home. The Job gets done this way, such seasoned people are rare. Now the idea is …

Think - Deliberate - Draw - Build - Test - Install

We all get stuck at the 'Deliberate' step, If its team work, a few should leave the desk and the conference rooms and start Prototyping and Simulating. This helps understanding a tough problem. Better still find a fast and simple solution.

Then there is that Sensational Site That Jake Built - The Steampunk Workshop. This is where it all Happens.

Recording Technology History

1877 - Edison made the first recording of a human voice ("Mary had a little lamb") on the first tinfoil cylinder phonograph Dec. 6 (the word "Halloo" may have been recorded in July on an early paper model derived from his 1876 telegraph repeater) and filed for an American patent

Dec. 24. John Kruesi built this first practical machine Dec. 1-6 from a sketch given to him by Edison that was made Nov. 29 (not on "Aug. 12" that Edison mistakenly wrote on another sketch in 1917).

Recording Technology History

Edison Phonograph

When Kruesi heard Edison's first words Dec. 6, he exclaimed "Gott in Himmel!" (but these words for "God in Heaven" were not recorded and thus have been forgotten). Others before Edison had tried to record sound, but Edison and his tinfoil phonograph were the first to succeed.

History of sound recording

The phonograph expanded on the principles of the phonautograph. Perfected by Thomas Edison in 1878, the phonograph was a device with a cylinder covered with an impressionable material such as tin foil, lead, or wax on which a stylus etched grooves.

RCA – Radio Corporation of America – History

RCA - Radio Corporation of America - Wayback Machine snapshot of RCA History.

Guglielmo Marconi, an Italian electrical engineer, transmitted the first wireless signal in 1895. By the turn of the century he had formed telegraph companies in England and opened the first wireless office in New York City. In 1901, Marconi telegraphed the letter "S" across the Atlantic Ocean. The U.S. Navy was so impressed that it replaced a flock of carrier pigeons with the "wireless" for ship-to-shore communications.

Two years after inventing the phonograph, Edison brought the world the incandescent light bulb. Thirteen years later, his start-up electric company would merge with the Thomson-Houston Electric Company and be renamed General Electric.

RCA - Radio Corporation of America

In 1929, RCA purchased the Victor Talking Machine Company, then the world's largest manufacturer of phonographs (including the famous "Victrola") and phonograph records. This included a majority ownership of the Victor Company of Japan, or JVC. The new subsidiary then became RCA-Victor. With Victor, RCA acquired New World rights to the Nipper trademark. This Trademark is also the trademark for the British music & entertainment company HMV who now display nipper in silhouette.

In the early 1920s, David Sarnoff publicly speculated on the possibility of "every farmhouse equipped not only with a sound-receiving device but with a screen that would mirror the sights of life." The idea of television was not new, and mechanical systems had demonstrated crude pictures. But it was Sarnoff's historic meeting with engineer Vladimir Zworykin that set the stage for RCA's success at electronic television transmission and reception.

Amazing Jacob's Ladder

So how do they work?  First two conductive metal rods are positioned in a rough “V” shape with a slight space between them at the base.  A sufficient voltage differential is provided from a high voltage transformer to breakdown the air in the gap between the rods.
