Some Fun Facts About Electronic Circuits

Electronic Circuits

Electronics, a branch of physics and electrical engineering, deals with the emission, behaviour, and effects of electrons and with electronic devices. The invention of the transistor showed remarkable potential for expanding the utility of electronic equipment. Other electronic devices such as pn junction diode brought about a significant development in the electronics industry. In this article, let us look at a few fun facts about electronic circuits.

Why are the circuit boards always green?

Printed circuit boards were first developed in the early 1900s. Earliest versions were constructed with simple wires that connected components by a series of pegs or posts. This type of connection was unreliable as these connections would crack and degrade over time. Now, manufacturers needed a non-conductive yet durable substrate to lay the conductive copper traces. One of the cheapest solutions to this was fibreglass that was bonded with a glass-reinforced epoxy-resin. Since the natural colour of this glass is green, the circuit boards appear green too. This circuit board construction material came to be known as FR-4. The FR stands for “Flame-Retardant” and is the most widely used PCB material.

What do the numbers and symbols mean on an Integrated Chip?

Usually, we notice a notch or dot on an IC. What you see is not an accident. This mark designates how the IC should be oriented on the circuit board. If not placed correctly, the chip will burn due to the input-output reversal. The next confusing thing in a chip is identifying the marks on the chip itself. Most integrated circuits have three lines. The rule of thumb is first the manufacturer – which is usually a symbol rather than text, followed by the model number and then a date code.

How small can components get?

There is a theory called Moore’s Law, which states that the number of transistors that can be placed in integrated circuits doubles every two years. The first transistor released by Texas instruments called the Multivibrator #502 contained only six resistors, four diodes and two capacitors and two transistors. Today, we have processors that contain 7.2 billion transistors.

The general observation is that the smaller the things become, the harder it is to predict their behaviour. The property of transistors is to direct the flow of electrons. At a quantum scale, this becomes difficult because once the insulating material directing the electrons becomes thin enough, they will no longer block the flow of electrons. Instead, it will simply let it pass through. In a circuit, this would cause a failure. Until this problem is addressed, there is a hard limit on how small transistors can be made.

When you convict your determination in the process, each day gets simplified. Start from the rooms you use seldom. And then significantly move towards in the order of increasing the environment. Check-in for the last place that seems crowded with things more. Don’t give it to the next days for a particular work. Try to complete each day’s work in that stipulated time only. Remember the adage that you should do things presently and not shift it to tomorrow.

Smart packing is the en route

When you shift from one corner of your house to a whole different place, you must pack rightfully. Don’t try to pull out everything from the shelves altogether. The smart way of packing is to concentrate on things distinctly. Check if the items packed are tied well or not, how many categories the boxes divided into, or how efficient packaging done or not should be your outlook. How safely the movers Sydney vehicle places it in their car needs to be ticked.

Make way for your checklist. Don’t throw any inventory. You might need it at any point in time. This is the most significant loophole most house shifters commit.

Circle the packing bags

If your packing gets done, then you should encircle the fragile boxes to be delicate and name linens and accessories to be that particular title. This way, you get to identify things quickly when you unpack. What happens when you keep aside packets by name is that when the movers and packers place the boxes onto the vehicle, they take proper care of glass and fragile substances? Avoid any form of damage, and the best way is to mark the boxes before packing or after packing. This depends on you. But you should mark taking the help of interstate removalists Sydney.

Keep away static materials

If you know, there are static materials that would induce electricity, then keep them in anti-static boxes. They are a perfect fit for electrical boxes. The bubbles are readily available in the market. Go and bring them to your house to avoid shock injuries.

A safe packing service will take care of the safety of your belongings. Check for the insurance of the company rendering packing services. Go ahead and make your Relocation act comfortable and hassle-free. Check for customer reviews before you hire any packers and moving companies sydney.

Full-Stack Developers v/s Specialized Developers: The Bigger Picture

Full-Stack Developers

Should I hire a full-stack developer or a specialized developer for my web project? Well, this is a million-dollar question! The answer to this question depends on multiple factors, which you will come to know as you read further.

Primarily, the deciding factors in such a scenario are the size of your business and project requirements. The purpose of this article is to highlight the benefits of each development approach and help you choose the best software development company. But before that, let’s get a complete picture of what the full-stack developers are and not what you assume them to be.

Let’s get started!

Background of Full-Stack Development

The term “full-stack developer” became an industry buzzword back in the 1990s and maintained its prominence until the early 21st century. Technically, these people were considered to be proficient in the use of both front-end and back-end languages, and also had some degree of knowledge in managing databases. 

This image will give you a good overview of the history of full-stack development.

So, the meaning and applicability of this term have broadened, especially in the past few years.

Current Scenario of Web Development

Technology is emerging and evolving, every day and every moment. Period.

In the midst of such evolutionary transitions, it becomes extremely important to team with people who know the depths of web development. 

You might be aware that the creation of an application goes through several stages that are as follows:

  1. UI/UX designers who create the layout of the future product.
  2. Front-end developers, who turn the design into code.
  3. Back-end developers, who are responsible for writing the code on the server-side.

Now, full-stack developers can handle the second and third aspects quite well. But, they might not be able to go into the ‘depths’ of these aspects. Depth, in this context, refers to the application of creative skills in stacks that only experts could do. The basic skills and knowledge don’t work anymore.

So, hiring specialized developers seems to be the key here. That being said, the full-stack guys are not bad. They are quite flexible. This is why Facebook exclusively hired only full-stack developers in the initial phases of their social media venture.

Thus, if you want to hire full-stack developers, they should have knowledge in almost a myriad of languages in addition to the basics. These include SQL, Bash/Shell, Python, C#, PHP, React Native and Angular. Take a look at the image below.

Keep in mind that mastering the basics of these languages and frameworks can take a developer around 5-10 years. So look for experienced people, always.

Pros & Cons: Specialized and Full-Stack Developers

By now, you might have got the idea that both types of developers can work for you, depending on the complexity of your project. In line with this requirement, let me tell you some individual pros and cons of each type of developer. 

Full-Stack Developer


  • Less professional burnout, offered by a frequent switch between tasks, leads to better quality and more satisfaction.
  • Universalism: an aptitude to debug everything, as well as to read and use almost any code.


  • Lack of knowledge of a specific domain. For example, a person who spent about 3 years mastering one skill will definitely be better than the one who spent the same amount of time learning multiple technologies.
  • Cannot expect creative inputs either at the frontend or backend level.

Specialized Developer


  • High quality of each completed part of the project.
  • Staying updated with the latest technologies.
  • Reasonable allocation of responsibilities, which is comfortable for both team members and efficient for the project’s needs.


  • Higher costs: hiring two specialists (for both back end and front end) instead of one is more expensive than working with a full-stack specialist.
  • Dependency on other team members.

In a Nutshell

I am summarizing the criteria for hiring full-stack or specialized developers in the table below. 

Small businesses with minimal space and hardware for mass hiring of developers. A business that needs expertise in a specific technology stack to enhance its operations.
Businesses that require flexibility in development operations and have no budget constraints. Businesses with a limited budget, with ample hardware and space to hire more developers.

Just take a look at this table if you ever feel confused about whether to hire a front-end developer or an all-rounder. Most of your doubts will be cleared. Good luck!
