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
"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."

He has many achivements to his credit; From converting a Thomas Saf-T-Liner, a flat-nosed diesel school bus into a family camper To a DIY Op-Amp Hot Tub Temperature Controller.
Look at Mr. Jake von Slatt, How he done things. This is what we learn from him …
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.

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
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 - 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.
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.

"The HP Memory Project is, first of all, a collection of vintage Hewlett-Packard hardware, software, documentation and other technical and marketing materials from HP's early years in the instrumentation and computer industry (beginning in 1939).
The HP Memory Project is privately funded and owned by its Curator. The Curator (Resources)
The HP Memory Project is not a commercial enterprise; it is a resource of technical and historical information relative to the Hewlett-Packard Company activities during the 1939 to 1999 period."
The National Museum of American History's Chip Collection consists of individual donations of objects, images and documenation that traces the history of integrated circuits.
The Chip Collection is a continuing work-in-progress concerning a small part of the permanent collection of the Division of Information Technology & Society's Electricity Collections.
This site's refrence pictures, diagrams, x-rays, thumbnail selections, and in some cases actual logbook pages in a single category to make your research faster.
An important though unusual aspect of the history of integrated circuit technology is buried deep inside many chips, we call this chip art.

Museum Of Electricity - Charles Brush
The General Electric Company was formed in 1892. It was the result of a meger between the Edison General electric Company and the Thomson-Houston Company, which themselves incorporated several other companies.
Electricity, technology, and lots of arcs and sparks!
Museum Of Electricity contains Vintage Electrical and Historical images and description. They include the Edison Lamp, Tesla Coils, Lightning and Atmospheric Electricity and the .....
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.
