Experts or beginners doing-it-yourself projects are usually unable to accomplish much because of dinky soldering irons and uncomfortable working place. However, DIY electronics kits are available which will make your work much more comfortable. Thus, you will be able to make and display your projects correctly. In this article, we will tell you all about DIY electronics and their kits.

 

Don’t let you electronics passion die! We are going to walk you through some of the best DIY electronics projects and recommendations.

1、Introduction to DIY Electronics

1.1 What is an Electronic Circuit?

Electronic circuits are the connections of many fundamental electronic and electrical components using electrical wires. Furthermore, these connections can be either on a breadboard or a printed circuit board.

 

If you are using a breadboard, then these connections are made through jumper wires. However, if you will use a printed circuit board (PCB) copper lines or pads will do the work of wires. They will smoothly connect any two components. Hence, electronics circuits on PCBs are usually neater and are preferred.

 

Nonetheless, you need to gain experience to make perfect electronics circuits on a PCB. Figure 1 shows the close-up of a printed circuit board with electronic components connected using copper lines, or traces.

3.1.3Microphone to Speaker Amplifier Circuit

A microphone cannot be directly connected to a speaker. Do you know why? It is because the electrical signal that it produces is not powerful enough to drive a heavy load. Thus, speakers will not produce noise if they are directed connected. However, we can add an audio amplifier in between them, and all will work out. Figure 12 shows a basic Microphone to Speaker amplifier circuit.
