Image result for telegraphTelegraph, the first device to allow people to finally “text “ one-another even an ocean away. I would be writing about more specifically about the electric telegraph.Basically a telegraph is a machine that is able to send information through Morse’s code. The telegraph was the first to send information to one place to another no matter the distance and in a matter of minutes! This means that important information like treaties, war status, etc could be sent without waiting weeks for a letter.


Image result for telegraphThe invention of the electric telegraph is mostly thank by two set of researchers: Sir William and Sir Charles Wheatstone also Samuel Morse and Alfred Vail. Morse and Vail helped to develop what now we know as Morse’s code which is made up of dots and dashes for each letter of the alphabet. While William and Charles are credited with building the machine itself in 1830s after the discovery of the first battery by Alessandro Volta and Hans Christian Oersted discovery of the connection between electricity and magnets. Soon their machine was used in British railroads station to the rest of the world in matter of time and grew since then.
In a basic wired electric telegraph, the setup is fairly simple. The is the telegraph key which basically is a switch. This mean that when the lever is pushed down the circuit is complete, creating a dot or a dash. This signal is then transmitted through the wire and then to a receive were the wire is wrapped around a metallic object creating an electromagnet. This could either attract an arm with a pencil on the end that is spring load, so when the circuit is complete it would bring the arm down causing the pencil to draw a dot or a dash on an piece of paper. The other way is allow the electromagnet to attract a metal object causing the “click” and “clack” sound. And of course all of this is power by a battery of some sort.

What does the electric telegraph serve in today’s world? Nothing.... It is as effective now as smoke signals. There is so much better options now like the internet, telephones, even pagers. It is still used in airplanes and such when voice communication become distorted because signals from a electric telegraph are difficult to become distorted. So at least the telegraph still has that going for it.



FUN FACT: Most common letters like the letter "e" have less complicated string of code while less common letters are the opposite.  



Got any recommendations? Feel free to send it in the comments what other technology you would like for me to cover!

    I’ve been telling you for years that we need to get some of these. It would be awesome to learn morse code! Anyways great blog! I look forward to next week’s.

    Morse code is something which I have always been interested in, and your analysis pretty much answered all inquiries I had on the subject. I loved your title, though it embarrassingly took me a little while to understand what it meant!...

    It is interesting to know about Morse code and the process of how it is utilized. I also have always been interested in Morse code and have been wanting to know to use it. Great blog!

    When I first saw the title of your post, I thought that it hadn't loaded right! Of all forms of communicating, morse code is definitely one of the more intriguing ones. How do Asian languages utilize it?

Dorito Power

Rotary engines, the official motor when burning oil is actually a good thing. The rotary engine or Wankel engine is much like chocolate ice cream in the car world, you hate it or you don’t. It is actually interesting concept because unlike other engine configurations, there is no cylinders. Instead they have a rotor which some claim to look like a Dorito spinning. The inventor of this odd engine was a Felix Wankel. Wankel was born in August 1902 in Lahr, Germany. He came up with the idea at the age of 17. It was only after 2 World Wars when he began working with NSU Mototenwerke in the research department without ever getting a degree or a driver license. He complete his design in 1954 and in 1957 and 1958 the prototypes were tested. In 1961 Mazda had contracted with NSU to produce the engine and install them in their cars. The engine was proven to be quite powerful in the 1960s and soon the engine was used by other car companies. The engine would began to lose its popularity in ...

Reelin' In the Years

Reel-to-reel, the final boss of the audio world. Reel-to-reel are one of the most expensive audio formats you are able to collect for. Top of the line machines can go up towards thousands of dollars and the tapes can go for hundreds of dollars too, depending on artist and band  of course. It is the go to format for many audiophiles and for good reason. So what justifies the price? Well before we go to that, lets talk about history. The reel-to-reel started it’s life in Germany in that late 1920s and did not have a name for it has it was since all magnetic tape recorders used it. Early tapes were made from papers and later plastic. Later on in the 1950s tapes where one-channel mono audio and used vacuum tubes. A company formed called Ampex Corporation which contributed a lot to reel-to-reel. Later on in mid-1950s two-channel stereo came into existent. The reel-to-reel would start to lose its popularity in the 1980s due to the cheaper compact cassettes. So what makes theses ...
