Cassette players are a technological device of the past, almost only the elderly use it. This tool was created by Lou Otten’s, he was a Dutch engineer who worked all his professional life in the Philips company. It was introduced in Europe by the Philips company in 1962, and in the United States in 1964, under a registered trademark under the name Compact Cassette. They cost $199.72. I think so because once he felt disconsolate and without the desire to do anything, it was when he came up to do something where he could distract himself and relax, these are the before and after images

The computers

Computers are a tool that are widely used today as they make it easier for us to do jobs, tasks, etc. this device was created by a British mathematician and computer scientist Charles Babbage The first mechanical computer was created in 1822 by Charles Babbage in London, its price when it came to market was USD 40,752.75 I believe it because Babbage tried to find a method by which calculations could be made automatically by a machine, eliminating errors due to fatigue or boredom suffered by the people in charge of compiling the mathematical tables of the time. He had this idea in 1812. This is how these tools looked before and after

TVs

Televisions are a device widely used by people today, this tool was created in 1926. Television was invented by John Logie Baird in 1923 in the city of Hastings, England and the first television image was broadcast by Baird in 1926. The images, which were initially dotted and flickering, were developed by Baird. its price when it came out on the market was USD 457.93, I think because John Logie Baird relied on the transmission of images by waves. The first time something appeared on a television screen was on January 26, 1926. The protagonist was the puppet of an inventor, John Logie Baird. This always believed in the possibility of transmitting images by waves, just like the radio did, these are the images of this device before and after

Refrigerators

Refrigerators, these devices, very useful since they allow us to store perishable products, this tool was created until 1834 when the scientist Jacob Perkins manufactured and patented the first fully functional refrigerator in the United Kingdom and which was perfected 10 years later by the American doctor John Gorrie, who sought to lower the temperature of his patients suffering from yellow fever. Its price when it went on the market was USD 837.67, I believe it because it was looking to lower the temperature of its patients suffering from yellow fever, these are the images of this tool before and after

Fan

A fan is a fluid machine or, more exactly, a device that transmits energy to generate the necessary pressure with which a continuous flow of air is maintained in different parts. this tool was invented in 1882 by Philip Diehl. This German engineer who emigrated to the United States had already invented the electric motor in the United States used in the first Singer sewing machines, and in 1882 he adapted this motor to be used in ceiling fans, I think so because when he carried out his work he felt that high temperature and uves decided to make a breeze with his shirt and then it occurred to him to create a fan to help him reduce the heat, this device had a price of USD209.54 when it went on the market, below I present the before and after images of this tool

Digital camera

smla086320 — 2022-08-19 20:31:04 UTC

Digital camera is a device used to capture images or photographs. It is an ancient mechanism for projecting images, in which an entire room performed the same operations as a current photographic camera inside, with the difference that at that time there was no possibility of saving the image unless it was drawn manually. the creator of this tool was an electrical engineer Steve Sasson in Brooklyn, New York, United States and he worked for Eastman Kodak when in 1975 he invented this gadget of electronics, the first digital camera, its price when it went on sale was $351.20, I believe it because when he went with his boss, they persuaded a laboratory assistant to pose for they. You could see the silhouette of her hair that's when she decided to create the digital camera these are the before and after images of this device
