A hobby is a non profitable human choice of act for passing leisure time. Practising technological facts are very popular and common choice as a hobby. This kind of hobbyist already has a preference and basic knowledge in science and they like to learn more and apply it in making technical things. Technology dependent pastimes are not for everybody for its relative complexity.
Electronics is a hobby for many people and they like to make electronics products by following circuit design. They have an interest in electronics and gain enough knowledge in this field. It is not always mandatory to have an academic education to make electronics products.
Someone can start with some basic knowledge and by practising he may gain lots of practical experiences. Amateur electronics hobbyist likes to make things for their own pleasure but in this process, they may make some good products and make some money out of it. Sometimes this kind of practice may lead to a new invention.
A favourite recreation from the field of mechanical engineering is making vehicles. For the production cost, plane or water vessels are not very popular, but auto mobile is a very accepted form of this recreation. Someone with a keen interest in cars normally wants to make his own car or at least modify it.
The ultimate goal is to make it faster but other modifications like new body designing, lighting, engine performance and sound system are important for the hobbyist. An amateur car enthusiast usually grows his interest in the car from childhood and at a time he wants to modify his own car in his own hands but it requires technical knowledge. Sometimes an amateur with enough practical knowledge may get a job at a professional car manufacturing company. There he can earn a lot of money in the field of his interest.
Almost same as making a car, making radio controlled instruments is a popular hobby for many people. It not only requires mechanical knowledge but also electrical and electronics knowledge. The mechanical part includes the body structure and making it workable. The electronics part for controlling it by wireless instructions and its circuit design. A common example of this kind of hobby is a radio controlled model aero plane. Most of the times, the hobbyist designs the plane by following one of his favourite original models.
Another new hobby, totally based on modern technology, is robotics. This pastime needs a lot of expertise in mechanical and electronics science. But another thing is very important for robotics and that is artificial intelligence. Modern robots don’t just complete the pre determined task, now they are able to make contact with a human. This kind of recreation needs a lot of education and skill.
Programming is a new but fast growing hobby among the young people. Programming and other computer related topics are totally dependent on modern technology. It needs a lot of knowledge about the working process of a computer to write a program. It requires some academic knowledge as well. Someone may be a genius and understand the basic techniques of programming with ease, but to make it perfect for practical use, he must have some education in the related field.
