If you enjoy playing and experimenting with electronics and circuits or even appreciate the idea of fixing electronics for fun, you must know what I mean when I talk about hobby electronics. All electronic hobbyists, like me, enjoy breaking down and finding how electronics devices work. Hence, hobby electronics lets us learn component by component.
Even if someone is not too familiar with electronics, sticking to a hobby for a long period of time can result in a significant amount of expertise. Beginners can try easier electronics projects and advance step by step to difficult circuits. As they start getting a better idea of how each electronic component works, they can experiment with more advanced circuits and have some fun.
For starters, you don’t even need sophisticated circuit boards or components. A simple circuit can be made by a simple battery consists of a single cell, a wire and bulb. Just tie the wire with the bulb and connect the other part of the wire with the battery. As soon as the circuit completes, electricity passes through the wire and the bulb lights up. This is the most basic circuit that anyone can make using simple parts that are easily obtainable.
If you have an interest in hobby electronics, there are some components that you can keep at home to play around for fun and understanding. You can even find electronic kits which are readily available to assist in learning. These kits vary in type depending on the age and expertise of the hobbyist. Mostly they comprise of batteries, resistors, motors, wires, capacitors, PCB boards, diodes and other components needed to make circuits.
Another simple circuit is one that can explain the purpose of a rheostat to any beginner. For this electronic circuit, you will need to get your hands on some basic components including a bulb, a typical steel wire spring, two dry cell batteries, a wire cutter and a wire.
Start by connecting the dry cells or batteries such that the two opposite polarities are connected i.e. the negative polarity of one is connected to the positive polarity of the second one. Then you have to connect the wires to the end of the batteries. Now connect one of these wires to the end point of the spring and the other wire to the bulb. You now need to connect another wire from the bulb and touch it with the spring.
What happens is the lesson of hobby electronics. When the loop completes, the bulb turns on. As you keep on sliding the wire towards the free end of the spring, the intensity of the light decreases. The basic concept to learn here is that steel spring is a bad conductor of electricity and when more of its length is included in the circuit, it offers more and more resistance. Therefore, a rheostat can be used for varying resistance across a circuit to adjust the current that passes through it.
Overall, the purpose of hobby electronics is not just to introduce a student or a hobbyist to electronics’ projects. The purpose is to instill in them the desire to experiment and design.
