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!

  1. 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.

  2. 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!...

  3. 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!

  4. 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?

Flip Floppy

Floppy disk, the official device of size does not matter and the symbol of every saving icon known to man. Much how the death of Jesus became the symbol of saving us from our sins in trade for His blood on the cross, the floppy disk eventually died off and became our symbol of saving files and document. Sure that may be a very odd comparison to some, but there has to be a reason why this old tech is still remembered in an age where physical media is on the decline and most of our files, photos, videos, etc are in the cloud. No other piece of technology is so recognizable, yet so unknown to many. The floppy disk was first introduced commercially in the late 1960s and these disks were 8 inches in size! These disk were mostly used by IBM computers in 1971 and were later produced and improved by IBM and other companies such as Memorex. The floppy disk got it’s name from… you guessed it… because they wobbly and flexible, even though IBM originally called it “Type 1 Diskette”, creative...

Automatic Safety

Automatic or passive seat belts, the great compromise between automakers and the United States government. Passive seat belts were one of those “safety” products that cause more harm than good for the end user. It was much hated by consumers and led to them only having a short life from 1990 to 1995. Now why were these seat belts a thing in the first place? Well the passive seat belts were invented by Volkswagen in 1972 and was first used in the Volkswagen Golf in 1975. This lead the Brock Adam, the United States Secretary of Transportation, to mandated that every car in to have either automatic seat belts or airbags by 1983. Now this angered many lobbyist who thought this was a way too soon of a deadline. In 1981 the mandate was dropped then transferred to the Supreme Court which lead to the mandate to stay, but now with an extended deadline of 1990. Now airbags were still a relatively new system which meant it was pretty expensive. Thus many car companies decided to go with pas...
