Technology over time continues to develop. At this time of course the old technology has been abandoned. But history has never forgotten technology just like that. Sometimes old technology. Can be an inspiration in this day and age. Not everyone knows technology. For ordinary people technology is not very important. But his presence has really helped a lot of people. Here are the kinds of technology in the past :
A. Compass
This tool is useful for determining direction. Inside the compass there is a metal coil that rotates with the movement of the wind. Although the compass is less precise in determining the direction. This equipment has helped many people in sailing to various lands.
B. Radio
Even if it's just the sound and not the picture. Radio has become a necessity for people at that time. Before TV, this tool was quite useful for listening to news broadcasts from various countries. So that people can know about the outside world. Old music can also be heard from here. This tool uses a wave transmitter in sending and receiving signals.
B. Blackberry
Android is not the predecessor of mobile phones. Blackberry is said to be the first generation to have a role in the popularity of mobile phones. Where this tool uses buttons and not the touch screen. Blackberry though is very simple. Has quite a useful function. Among them is as a social media tool such as BBM. Where two or more people can chat with each other. So we can send messages to each other via the internet. In addition to its main function in sending messages and calls using cellular services. On the other hand, some 2D games can also be played in it. Although the absence of a touch screen makes it difficult to play.
C. Steam Train
What we called trains before were not powered by electricity but using steam. Steam train is a general term that people are familiar with. Long ago trains still used coal as a fuel to produce steam. This tool though the way is not as fast as now. Has been able to bring many people to various destinations. The wheels still use rotating iron that runs on rails. And his trademark is a small funnel on his head where the steam is dispersed into the air. People must know the distinctive sound of a horn. This train has been abandoned a lot because its use pollutes the environment and is ineffective.
D. Handheld Telescope
The thing most people look for when they want to see the distance from a distance is this tool. Handheld telescopes really have the ability to see objects from a distance within a few meters. Like today's magnifying glass but not to see small objects like bacteria or viruses. It helps people in seeing what is going to happen somewhere. For example, the arid desert. Where this tool can be shortened or extended.
E. Black and White Camera
Why is it called by that name? Because a black and white camera is a camera that cannot produce color at all. Its capabilities are not as good as today's cameras. To produce this type of camera image using a copper plate as a mediator. So that when a pseudo image is generated, it will appear. In addition, the storage capacity is also not much. But in the investigation of crime cases this camera is very useful. One of them is in keeping traces of criminals.
The technology above is of course now difficult to find. But their existence will not be lost in history. It is possible that in the future, past technologies will be reassembled and combined with today's technology. Who knows what will happen in the future. Are you interested in buying it and try it.
