How to Use LinkedIn Effectively During Your Job Search

LinkedIn is widely regarded as the top social networking platform for connecting recruiters to job-seekers. Even if you aren’t looking for a job, LinkedIn keeps you updated about new openings in your field. This helps you to find better jobs quickly when you decide to leave your current job. Over 20 million recruiters use LinkedIn to attract potential employees, and over 35.5 million people have gotten employed via connections here. If you are able to use LinkedIn effectively, you too can get your dream job. LinkedIn allows recruiters to learn about your past experience and skills from the first glance at your profile. This creates a first impression in their mind about you as a prospective employee. So be sure that you use the platform to its full potential. If you want to switch to a new field, you can use LinkedIn’s latest tool, Career Explorer. In this article, we will tell you about how you can use LinkedIn to gain more connections during your job search to boost the process.

1. Update Your Profile

It is important that you keep your profile updated with your latest jobs and skills. Add your contact details such as your e-mail ID to your profile so that recruiters can easily get in touch with you. Your profile picture and headline is the first thing anyone sees on your profile. Use a professional picture as your profile picture, and update your headline to highlight your position and current job. Be sure to add all the skills that you have. The more skills you have on your profile, the more visibility it gets. You can also post visual content here about awards or certificates you may have won. This is especially important for content creators as you can also post your best works here which will impress recruiters.

2. Build Connections

By having more first degree connections, you can increase your profile’s exposure on this platform rapidly. You can connect with more people by importing your contact list from your e-mailing platforms. You may even find out that someone you know is a part of the organization where you want to work. In such a case, you can ask them about job openings or request them to introduce you to the recruiters. Putting in a word with someone who works in the organization can do wonders for your chances to get employed there.

3. Research Companies

Prepare a list of the companies that you would like to work in and find them on LinkedIn. This is quite easy to do, you just need to type in the name of the company in the search bar. Once you have found the company’s profile, follow it. This will keep you updated about job openings in the company and you will be able to view these updates in your news feed.

4. Announce Your Availability

Recruiters need to know that you are available to work. You can make this known by adding it to your headline. For example, “Archaeologist ready to find treasures for you” can catch a recruiter’s attention. So be creative with your headline. Avoid simply saying that you are looking for a job as that may seem a bit desperate and it doesn’t work well with employers. You can also directly contact companies that are looking to hire so that you have a higher chance of making it, rather than wait for them to notice you after you apply through LinkedIn. 

5. Get Active

Post content you create, comment on other people’s posts, get involved in conversations on LinkedIn. This is the best way to gain a presence on this platform and get noticed by recruiters and employers.  You can also use the Advanced Search feature to find professional groups in your neighbourhood. By interacting with such groups, you can grow your network exponentially. The bigger your network is, the more exposure you gain and the more people will find you on LinkedIn. It’s best if you use this platform to network with people after working hours. Since most people are busy during working hours and will not be active on LinkedIn, you can get a higher response rate if you are active after working hours. Apply these tips to your LinkedIn profile and get your dream job! As a professional, it is important that you keep yourself updated about jobs in your industry so that you don’t have to search for them after you have left your current job. If you are on the lookout for jobs, you must update your other social media profiles as well. Recruiters will often check out these profiles as a sort of a background check. So make sure that you do not have anything inappropriate on your other profiles.

IRFZ44N MOSFET Characteristic Curves in Proteus ISIS

Hello Learners, Welcome to another useful tutorial at The Engineering Projects. In the world of electronics and circuits, many useful devices are designed that can minimize the requirement of large and complex circuits. At the Present time, we are working at such a device works very near to the base of many circuits i.e, IRFZ44N MOSFET. We'll  approach to the answers of following Questions:

1. What is IRFZ44N MOSFET?
2. How is the Structure of IRFZ44N MOSFET?
3. What is the working mechanism for the IRFZ44N MOSFET?
4. How can we find the characteristics of IRFZ44N MOSFET in Proteus ISIS?

You will have some important chunks of information about the topic in DID YOU KNOW sections.

What is IRFZ44N MOSFET

As you can see, MOSFET is a acronym of Metal Oxide Silicon Field Effect Transistor. We introduce the IRFZ44N MOSFET as:

IRFZ44N is an important type of N-type MOSFET that consist of three pins, have a hgh Drain current and a low Rds Values.

It is the type of IGFET( Isolated Gate Field Effect Transistors). A large amount of MOSFETs are used as switch every year. When we compare it with BJT , we find that it requires almost not current to control the load current unlike BJT. If you want in-depth study on this mosfet then you should have a look at IRFZ44N Datasheet.

DID YOU KNOW ???

MOSFET is a semi-conductor device that is Fabricated by the Controlled oxidation of Semi-conductors (Silicon in most case). It can work in both modes of operations i.e, Depletion and enchantment.

Structure of IRFZ44N MOSFET

When we observe the IRFZ44N MOSFET we find that it consist of mainly three pins as described below:

Pin Number	Pin Name	Role
1	Gate	Controls biasing
2	Drain	Current input
3	Source	Current Output

Vgs: The IRFZ44N MOSFET is a voltage controlled device that means it can be turned on and off when we apply a required threshold Voltage. This voltage is termed as Vgs. Vds: It is the absolute Maximum Voltage of IRFZ44N MOSFET between Drain and Source. This is salient characteristic of IRFZ44N MOSFET because during the operation of IRFZ44N MOSFET Drain-source voltage should kept less than maximum rated value. Here D Stands for Drain and S stands for Source. Ids: It is the amount of current that passes from Vds to the IRFZ44N MOSFET. The direction of this current is important during the Operations of IRFZ44N MOSFET.

DID YOU KNOW ???

The MOSFET is a better version of Junction Field Effect Transistor. Due to the limitation of JFET for the conduction in one side only ( some time it is the advantage), the Designers made a new type of Transistor that can change the conductivity when the amount of applied voltage is change and named them as MOSFET.

Characteristic Curve of IRFZ44N MOSFET

The quality and the suitability of any transistor is checked through its characteristic curve. The characteristic curve of IRFZ44N MOSFET have two phases.

1. Depletion Mode
2. Enhancement Mode

Depletion Mode

In this mode the Transistor is closed during the zero bias voltage at gate terminal. Hence the IRFZ44N MOSFET  is said to be switched ON. The channel width increases when the Gate Voltage is increased to the positive side. in return, the current Ids increases. During the situation when Gate voltage's value is decreased, the Width of the channel decreases and Ids follows the same rule.

DID YOU KNOW ???

The IRFZ44N MOSFET is also known as the Power MOSFET. It is 22oAB through hole package that has three pins. The top metal tab is also called the drain because both of them are same.

Enhancement Mode

This mode is usually considered as normally open switch as the transistor does not conduct the current when the Gate Voltage is zero. If we apply a positive voltage to the gate then a Drain current follows through the Gate. The Enhancement mode of IRFZ44N MOSFET  enhances the channel because when the Drain current's value is increased the channel width increase and the decrement of the width is for vise versa.

IRFZ44N MOSFET Characteristic Curve in Proteus ISIS

To understand the whole discussion mentioned above, Let's make a characteristic Curve of IRFZ44N MOSFET in Proteus ISIS. To do this, just follow the simple steps given next:

• Power up your Proteus software.
• Go to Pick Library by pressing the "P" button given at the left side of the screen.
• Choose IRFZ44N MOSFET.
• Arrange the Transistor at the working area.
• Go to Terminal Mode from the left most side bar of the screen.
• Choose Ground Terminal and set it just below the IRFZ44N MOSFET.
• Go to Generation mode and select DC.

• Set one DC probe at the left of the irfz44n MOSFET and take another and set it at the upper side of irfz44n MOSFET.
• Connect at the components set until now with the Help of Connecting wires.

• Select the current probe and set it just after the Vds. Make sure its direction is toward the irfz44n MOSFET.
• Go to Graph Mode>Transfer and set a Transfer Graph just after the Circuit.

• Right Click the Graph>Edit Properties>Set the Vds as Source 1>Set Vgs as Source 2>click Ok.
• Right Click the Graph>Add Trace>Set Ids as the Probe>Click ok.
• Right Click the Graph>Simulate.
• You will Get the required output:

Hence, in this article, we learned about the IRFZ44N MOSFET, we saw the introduction of IRFZ44N MOSFET, Learned about the structure of IRFZ44N MOSFET, saw some important concepts about the IRFZ44N MOSFET and performed a Practical Implementation of IRFZ44N MOSFET for the Characteristic Curves in Proteus ISIS.

Water Heater Maintenance Checklist

Hello Readers! Today we'll talk about the , maintenance of water heater. To ensure that your home's heating system runs smoothly, you require multiple pieces of equipment. A water heater is of the most importance. Every household needs a water heater for numerous external and internal needs, such as the uninterrupted flow of warm water in the winters, washing tough stains off clothes, and sometimes cleaning and disinfecting surfaces with a mixture of warm water and antioxidants. Since multiple parts of a water heater tank are in regular use, wear and tear are unavoidable. To ensure that your water heater lasts longer and continues to operate smoothly, read on. This article will take you through a heater's series of components, discussing a checklist that should be religiously followed for safety, security, and maintenance purposes.

Inspect and examine its outer unit

The outer look of the water heater will tell you a lot about its condition. While inspecting it from the outside, you need to focus on a few things such as:

• Leakage in a pipe. According to a study, almost 10,000 gallons of water go to waste due to pipe leakages. The reason behind a leakage can either be a faulty pipe or an old water heating tank that has been used beyond its lifespan. If you notice anything of this sort, please contact a reliable plumber to fix it in the long run.
• Insufficient water storage and weak pressure. Sometimes, due to the leakage in the tank itself, the water keeps pouring out, weakening the top floors' temperature control and water pressure.
• Rusted and eroded tank bodies or pipes can cause significant damage to the water quality affecting your health.
• Try to inspect and mend these problems every month to avoid a more significant issue in the end.

Cleanse and rinse out water through it

A tank's purpose is to store water in large amounts. However, this water also contains certain chemical elements, which can cause erosion of tank walls if not rinsed thoroughly and routinely. Calcium Carbonate (CACO3) is a widely known component found in water. The nature of this element is harsh and erosive. It can't quickly rinse off through the tank walls and often contribute to the tank's thinning and rustic appearance from the inside and outside. Other than that, CACO3 leaves behind a hard crystal-like residue which can block the pipes passageway from the inside, clogging the pipe openings. To prevent this, make sure to efficiently use softening and filtering agents for taking CACO3 off the edge for the same and uninterrupted consumption of warm water. The ideal procedure accounts for emptying the tank on a bimonthly basis, leaving it open for a while for water saturation, and then rinsing it off at least thrice with clean water of normal ph.  

Check-up on the efficiency of pressure release valve

Pressure and temperature valves are also essential and need to be regularly inspected. T&P Valve can cause significant damage to the tank and people around it if not checked on a bimonthly basis or however often it needs to be examined based on its intensive usage. T&P Valve is specially designed to neutralize and balance the temperature and pressure levels inside of the tank. The pressure and weather must be simultaneously managed to avoid any extremities such as an explosion. People often neglect to form an equilibrium among the two metrics, which results in life-threatening situations. The maximum temperature and pressure recorded are (210 Fahrenheit/150 Imperial pressure stress); at this point, the situation is alarming. The valve should be released with turbo speed for safety purposes. What happens is that the increased temperature of water triggers evaporation in the form of vapors. This continuous conversion of water in mists increases the inner temperature and hikes it up to a bursting point. Therefore, checking on the speed and pressure of the T&P valve regularly can turn out to be a beneficial practice for the lifespan and hot water heating system maintenance.

Transpose the Anode rod regularly

As per the precautions mentioned in the hot boiler inspection checklist, because of constant corrosion and filtration, an Anode rod is made a compulsory feature of water heating tanks. It is placed on the top of the tank, attracting all sorts of elements that can cause oxidation. The Anode rod is usually made up of Zinc, Magnesium, or Aluminium. Anode rod is typically designed to prevent oxidation within the tank for two significant reasons:

• A water heater tank is a closed crafted vessel with high pressure and temperature modes, which induce oxidation faster.
• Oxidation typically sets a thick layer of oxidized elements that can quickly erode the tank's walls, linings, and surface. Anode rod slows down the oxidation process safeguarding the inner and outer linings of the tank.

Any openings, leakages, or divulgence present in the tank nullifies the Anode rod's operational function. They increase the mixing of additional oxidized elements, making the oxidation process faster and more serious. If you cannot manage this on your own, consider having an HVAC maintenance plan, A licensed and well-known entity for treating critical plumbing, leakage, and various other issues of a hot water tank and related home appliances.

Adhere to the checklist and make a move now!

This water heater maintenance and inspection checklist is a step to step guide, highlighting the substantial parts of a hot water tank. If you have been neglecting any of the pointers mentioned above, hasten up and run a thorough inspection to lengthen the life of your water heating tank by taking easy precautions.

2-bit Full Subtractor in Proteus ISIS

Hello mentees! Welcome on the behalf of The Engineering Projects. We are here with a new lesson about the Digital Logic Circuits. Logic Circuits work as heart in many electronic Circuits. The topic of today is Full Subtractor in Proteus and you will find the answers of the following questions:

1. What are 2 bit  Full Subtractors?
2. How can we design the Truth Table of 2 bit Full Subtractor?
3. How can we implement the 2 bit Full Subtractor in Proteus ISIS?

You will also learn some important chunks of information in the DID YOU KNOW sections.

2 bit Full Subtractors

A full Subtractor works really well in the processor. We’ll talk about it function but before that have a look at its definition:

• 2 bit Full Subtractor is a Combinational Logic that contain three Inputs and Two outputs and perform the function of Subtraction with two bits.
• Minuend: The 1st input is called the Minuend used to take the bit from which the 2nd value will be Subtracted.
• Subtrahend: It is called the 2nd input that is subtracted from Minuend.
• Borrow in: It is the third input that is use to take the value of the Previous borrow and we’ll denote it as B(in) here.

• Borrow Out: The Borrow out is symbolized as B(out) and it the resultant borrow that the output Terminal shows.
• Difference: This is the main result that was the concern of the experiment and its value totally depends upon the binary subtraction rules.

DID YOU KNOW?????????????????

There is another circuit called Half Subtractor that is used for the subtraction of bits but the foremost disadvantage of that circuit was its inability to work with the borrow taken in the previous calculation and the designers worked for another better Subtractors.

Truth Table of 2-bit Full Subtractor

If you know about the Concept of binary subtraction, you can use your knowledge to generate a Truth Table of 2 bit  Full Subtractor so that one can design a feasible Circuit of 2 bit Full Subtractor. The Table contain all the records that can be possible for our experiment and its result into the bargain. Thus the Truth Table for the Full Subtractor is shows as:

Minuend	Subtrahend	B(in)	Difference	B(out)
0	0	0	0	1
0	0	1	1	1
0	1	0	1	1
0	1	1	0	1
1	0	0	1	0
1	0	1	0	0
1	1	0	0	0
1	1	1	1	1

Working Mechanism of 2 bit Full Subtractor

When we observe the Circuit of 2 bit Full Subtractor, we found that it is combination of two circuits of Half subtractors and the output of each circuit is then fed into an OR Gate through which we get the output of borrow. We have two types of outputs in the 2 bit  Full Subtractor:

1. Difference
2. Borrow

DID YOU KNOW?????????????????

The Full Subtractor is the one of the most fundamental Logic circuits of that are used for two bit subtraction in many computing system.

Let's have a look at the procedure of calculation of both.

Difference

The binary subtraction is similar to the decimal subtraction but it works with only two digits called 0 and 1 instead of 1 to 10 in the decimal. When we examine the answer of the bit difference while using a Truth Table in the Half Subtractor circuit, we found that it is identical to the XOR Gate. Therefore we use a XOR Gate for the Difference that is introduced as:

The type of Logic Circuit that gives the output HIGH only when both its inputs have inverse value to each other and vise versa. 

Thus the truth table for the XOR Gate is given as:

A	B	A XOR B
0	0	0
0	1	1
1	0	1
1	1	0

The output of the XOR Gate is Fed into another XOR Gate for the Full subtraction which has the connection of a Borrow Input B(in) at its Second input.

DID YOU KNOW???????????????

The Application of the  Full Subtractor is found in the ALU of computer where they are responsible for the Graphic application to decrease the difficulty in the CPU and GPU.

Borrow

Many times, the situation arrives when the Minuend<Subtrahend and in this way, the circuit need to borrow a bit from the bit presented just after it. The Full Subtractor do this through the AND Gate that contain a NOT Gate at its one end. For full Subtractor, this arrangement is again fed into the duplicated circuit and the both the outputs of this AND Gate is fed into the OR Gate that gives us the Borrow(out).

2 bit Full Subtractor in Proteus ISIS

• Start up your Proteus Software.
• Collect the following devices from the Pick Library.

Devices Required

1. XOR Gate
2. AND Gate
3. OR Gate
4. Logic Toggle
5. LED-Red

• Arrange the XOR Gate, AND Gate and NOT Gate at the working area according to the arrangement given below:

• This will form a Half Subtractor. Select the devices through a square selection area.
• Copy the whole arrangement through left click>copy to clip board.
• Paste the arrangement in the side of the circuit.
• Add an OR gate at the right side of the system. The screen should look like the image given below:

   

• Add three Logic Toggles at the left most side of the arrangement.
• Connect the Whole circuit through connecting wires by matching the circuit with the following image:
• This is the Full Subtractor circuit. Change the values of the Probes according to the Truth Table and record your observation.

  Consequently, Today we learned very useful circuit of Logic Design. We saw what are 2 bit  Full Subtractor, how can we design a  Truth Table of 2 bit Full Subtractor, what is the basic mechanism behind the working of 2 bit Full Subtractor and how can we perform a Practical implementation of 2 bit  Full Subtarctor using Proteus ISIS. In the next session, we'll learn how can we simulate a four bit Full Subtractor in Proteus ISIS and its basic concepts.

Virtual Private Network (VPN) - All you need to know

You must have heard about the VPN. It's a much common phrase these days. Many teenagers use this service to browse online, stream the content and get the location prohibited services online, but the actual meaning of VPN is a lesser-known fact and why VPN was introduced is rarely known. In this complete guide about VPN, you'll learn everything about the VPN- the intro, history, usage, types and benefits.

Introduction to VPN

VPN is pronounced as Virtual Private Network. As its name suggests, VPN is a private network connection that serves the purpose of data sharing, privately, among several connected devices. All the computers, mobiles, laptops and other devices connected through this virtual private network can share the data with secured encryption that cannot be observed by anyone else. That's why it is called a private network. It serves the purpose of security.

A typical VPN performs data encryption up to 256 bytes. Data encryption means that your original data is being transmitted into a different complex language that needs to be decrypted for understanding. That's why, when you surf the internet via VPN, all your data log is encrypted and no internet service provider can see the actual data. They just see a connection between a random IP and the VPN server. The encrypted data seems garbage to them. Here's a list of a few best online VPN services:

• SurfShark VPN
• Nord VPN
• ExpressVPN etc.

History of VPN

VPN was introduced in 1996 just for the sake of sharing the team data, remotely, via a private network. It made the team eligible to connect the company's device via a secured connection. Later, many military and government sectors shared their resources and their devices via virtual private networks so that any core member of the department could access the data anywhere online.

These private networks made sure the data encryption as well. No other internet user or service provider could actually see their transaction details. That's how the VPN appeared as a handful yet secured network.

With the passage of time, a corporate sector adopted this private network method as they could not afford to reveal their specific business models and strategies online with anyone; therefore, they made their own virtual private networks to deal with their international staff via a private network.

VPN Structure

A virtual private network means private network access to a public network connection virtually. There are different protocols used in building a secured VPN. Whenever a person is connected through a VPN, his browsing history and login details won't be accessible via a public network. It does not matter if he is using public Wifi or not, his all browsing history is encrypted with several protocols.

Pros/ Advantages of VPN

VPN helps us in getting:

• Secure connection
• Better Internet Speed
• Access to the restricted platforms
• Chance to go global
• Rid of censorship
• An untraceable IP
• All international offers
• Secured data log

Secure connection

The very first and foremost usage of the VPN is building a secured line of data transmission which cannot be traced, manipulated or hacked by any service provider.

All the data which is transmitted by a VPN is encrypted in several layers and the service provider can just see a connection between them, not the actual data which is being transferred.

That's why most of the banking sectors and e-commerce stakeholders have their own VPNs. Otherwise, all the private credentials can be hacked or manipulated with some medium level hacking.

Better Internet Speed

As you have known that VPN is a private network, so it works as a dedicated server between both ends. We may receive lag in our public network connections due to a burden of overload traffic but the VPN works as a sole private network that is dedicatedly available to you. Regardless of a normal public connection speed, VPN always offers you a better speed than a public network.

That's why many streamers and professional gamers now have to have a premium VPN service for the best speed.

Access to the Restricted Platforms

We are living in a highly diplomatic and highly competitive era. Many international countries and brands have to restrict their services due to their diplomatic policies like China and Saudia won't allow you to use Facebook and Google etc. In the same way, some countries won't support the PayPal and Netflix streaming services. If you are traveling or staying there for a while, you still can access your PayPal and Netflix subscription there with the help of a VPN.

If you still want to use any international service without any local restrictions, you need to have a VPN service.

Chance to Go Global

One of the most fascinating things about VPN is about connecting to the internet from any country's local network. You can select your favorite county's network to connect with and then all your data surfing and browsing would be done with that particular network.

Most of the time, any internet geek or E-commerce geek chooses VPN to collect data and statistics for an international forum. For example, whenever you type a certain keyword in your browser, you will see some top suggested queries by your browser. Those top suggestions are based on the most common search queries from your nearest areas. Hence, you can connect to another country's network via VPN and collect a different data set by searching the same query in your browser. It would give you top search results from that particular location.

Any SEO guru can do this to master the keyword-finding technique. Probably most of the keywords finding tools perform the same algorithm to gather the top ranking keywords in different parts of the world.

Get Rid of Censorship

If you ever feel rejected, restricted by the national censorship laws and some international forums and you just can't share any bold content or speech of your desire. You can achieve that freedom of speech after getting connected with any VPN service. You can then easily share your ideas and content from a different location.

An Untraceable IP

In a normal routine, you are easily traceable and trackable of your all activities via your internet devices. All your banking details and your bank transaction can be hacked with ease on a public network. You can even be traced with some medium to advance hacking tools. Hence, you are nothing but a caged person in this miserable public network connection. So, you may get an untraceable IP each time after getting connected with the VPNs. Each time you get connected to the VPN, you get a new IP address that cannot be traced back to your device.

Redeem All International Offers

As you have already understood much about VPN, you should be aware of the fact that you can change your log-in location with the help of a VPN. Now here comes an exciting part. Many companies and brands present special deals and discounted offers for specific countries or regions at some specific local festivals. If you have a VPN service, you can easily redeem the discounted price after getting logged in from that particular location.

In another case, you can even purchase online from different locations to have a fair deal. For example, AliExpress provides a different rate for Chinese than Europeans.

Secured Data Log

Have you ever wondered about the internet ads process? How do they belong to you every single time? How can they appear at the right place at the right time? How is it possible for those advertisers to know your personal interests and your personal needs?

Well, it is an alarming yet awakening fact that every single free social media service provider keeps logging and storing your personal data from your device. Whenever you download the free apps, they ask permission to access your microphone and camera. There you fall into a trap. They can know every single thing about themselves through your device. They sell that particular data to those third-party apps, so they can lure you with the most relevant necessities. That's how the whole online advertising model works. That's how all these free apps are still able to provide you so-called free services because you are not paying for their products but you are yourself a product. It is what it is.

Cons/Disadvantages of VPN

Despite all the pros of VPN, there are some cons of VPN as well. The most common disadvantages of VPN are:

• Extra Cost
• Illegal activity

Extra Cost

To have a secured and premium service of a VPN may cost any particular regular charges which you have to bear as an extra for surfing the same browsers along with the VPN.

It won't cost much to any individual but on a larger scale, VPN costs the corporate companies and banking sectors a handsome monthly amount.

Illegal Activity

We know that we are living in the high-tech era. Every single good soul is using the internet so as the evil ones. That's why government institutions and your national internet service provider keep tracking your internet activities all the time. If any fraudulent or terror activities are to be done somewhere, they try to trace it via their logged data and eliminate the threat before a threat eliminates us.

That's why many countries won't encourage VPNs as they consider it a risky approach for common civilians. If it is encouraged openly, then every single person would be doing it and they can't differentiate between anyone because they won't be able to decrypt the encrypted surfing data. Anyone with bad intentions would be a major threat if he would be using the VPN each time before going to the internet. That's why all the security institutions won't allow any open usage of the VPN. They are interested in tracking your records for your safety; however, you won't be having your free private life.

Types of VPN

There are many types of VPN services available in the market nowadays. Most of them are free but they have their limitations and other premium VPs are good options too. Following are the details about several types of VPN.

Free Routers VPN

Free routers VPNs work as just the router. They just redirect your internet requests to the private network and all the responses from the public networks against your search queries revert back to you from the same private network connection. There is no direct network connection between the public network and your device. You can get a new random IP address each time while connecting to that free VPN. So, your location is untraceable.

These free VPNs are most favorable towards newbies and freebies. Almost all teenagers use such free VPNs to stream their favorite content platforms like Netflix, Hulu and Sonyliv etc.

The major benefit of such VPNs is that they won't cost you some extra bucks but they are not much feasible as well. They are usually slower than premium ones because many people use their free services and their server is usually down due to heavy traffic. Moreover, their security is not as much safer as it should be. As they also have an advertisement revenue model for their return of investment (ROI), you are still on the verge of losing all your data online to some specific advertisers. That's why you observe many ads even on VPNs.

So these are not trustworthy for secured businesses. They are just valuable for youngsters for steaming the restricted games and apps free of cost.

Premium VPNs

Premium VPNs are dedicated VPNs for your network connection. They are not rushy as there are no freebies there on their server. Only mature and serious peeps buy their membership to have either a better speed of internet or much safer protection for their online surfing. In such premium VPNs, several layers of VPN protocols are added and your data is made fully encrypted. Further, your one-session data expires- once you logged out from that private connection. That's the most attractive part to buy a premium service of a VPN as it gives you full control and assurance about your protected internet surfing.

These premium VPN services have several backup servers on their end, so their speed is rarely compromised.

Such VPNs give freedom of speech and free life- a true meaning.

FAQs about VPN

What is VPN?

VPN is a virtual private network that allows you to access the public network, privately. It was built for just accessing office resources remotely in 1996. Nowadays, it is working as a proper proxy network to access all the restricted platforms. You can secretly browse anything from your PC and your IP address and browsing history won't be tracked.

What is the purpose of a VPN?

There are several purposes of VPN as it behaves as a separate private network connection providing a speedy internet, secured internet and ad-free service; plus, it gives you an opportunity to access all the restricted services and international offers. Some corporate companies and banks use their own VPNs to make their data secure via their own private network.

What are the Pros/Cons of VPN?

There are several pros and cons of a VPN. The major pros of VPN are data security, speedy internet and providing access to any restricted media by changing your geometric location and IP.

The cons of VPN are the extra expenditure and a risky approach to a probable violation of the law according to some specific countries.

How to check the quality of any VPN?

You should check its capability of providing secure 256 bits data encryption. You should check whether it has as many locations as you want or not. You must check its assigned IP addresses beginning- it must match with that particular location's IPs. You should also check the internet speed via that particular VPN. It is supposed to give you a higher speed.

Should I go with free VPNs or Premium Ones?

Obviously, it is preferable to go with the premium ones as they provide better privacy and speedy service than free ones. However, if you want to just access your favorite show or game which is restricted in your location, you can go with the free ones. Don't try to process any secret data like banking or credit card transactions while using free VPNs.

How do I connect with a VPN Service?

It's not a hectic task nowadays, you can just simply download an app from the play store or an app store and the app sets up a VPN connection on your public internet automatically assigning you a random IP of a different location. However, you can set up manually via VPN settings in your network settings.

For a Windows PC, you need to sign up with your VPN service providers and establish a username and password once.

Once you have got your VPN subscription, you can simply go to the network settings and create a VPN server choosing a specific IP address, username and password.

Then you just need to connect with that particular VPN network each time. It works as a proxy network in your windows.

How to Determine What Wattage of Solar Panel I Need to Choose

Hello! I welcome you on the board. we'll talk about the Solar Panels and it wattage to choose the solar panel according to the need of time. The performance and efficiency of a home power plant directly depend on the correct choice of solar panel characteristics. Innovative technology has made it possible to create a record 400 watt solar panel, which is currently the most efficient and economical. To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel.

Choose the Type

To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel. There are 2 main types of solar panels:

1. MonoCrystalline.
2. PolyCrystalline.

MonoCrystalline panels have great performance but only work when exposed to sunlight at an angle of 90 degrees. It is more efficient to install them in large solar power plants, where high output is important.

Polycrystalline panels work at any angle of inclination of the sun but have lower productivity. This type of module is more suitable for installation at home since they have a lower automatic start threshold.

Define the Brand

If it is important to you that your solar panel works efficiently and for a long time, take a closer look at the manufacturer's brand. Choosing the right company will provide you with excellent product quality.

It is best to choose from the "Tier1" list. Here are the top manufacturers from all over the world. As of 2020, the leading companies were:

• Jinko
• LONGi
• Solar
• Risen
• Trina
• QSells
• Talesun
• Astronergy
• Jinergy
• LG

Calculate the Power After you have chosen the type and manufacturer of solar panels, you should proceed to the most important step - calculating the power. To do it, you need to know exactly how much power you are using. There are two ways to do this:

• Check data on meter readings (less accurate)
• Independently calculate all electrical appliances, their power, and operating time. This way, you can get the most accurate result.

Also, you need to add about 20-30% to the resulting value. This is the energy consumption of the inverter and the accumulator of the battery itself. After that, you need to look at the indicators of solar radiation for the required city. For example, this figure is 0.8 for winter and 5 for summer. For solar panels to operate at full capacity, it is important to receive direct sunlight at an angle of 90 degrees. This figure cannot be achieved throughout the day. Thus, solar panels can only function at 30-70%, depending on the region of location. Also, you should keep in mind that the panels produce energy only during daylight hours, which, in the summer period, are approximately from 8-9 a.m. to 4-5 p.m. In the autumn-spring and winter period, this number decreases significantly. The panels do not function at night but accumulate energy generated during the daytime.

Follow the Formula 

The formula for calculating the power of a solar panel looks like this: W = k*Pw*E.

• Where «k» is a fixed index – 0,5 in the summer period, and 0,7 in the winter period
• Pw – the power of a battery;
• E – solar radiation index for the selected period

If there is a 310-watt solar panel, and the solar radiation index is 0.8 for winter and 5 for summer, then W = 0,5*310*5 = 775 watt per hour in summer W = 0,7*310*0,8 = 174 watt per hour in winter For example, you have calculated the total energy consumption of your house and got 6,000 watts. Also, we have to add approximately 30%. So, we receive 6,000*1,3 = 7,800 watts.  Now, we have to divide the total energy consumption on the W index: 7,800/775 = 10; 7,800/174 = 45. So, to cover all your needs, you have to install 10 310-watt solar panels in summer and 45 in winter.  Thus, based on the results of calculations, you can independently adjust the area and power of solar panels. Everything depends on your needs and desires.

Client Invoice Tips: 10 Ways to Invoice Clients Better

Hello Reader! Welcome to The Engineering Projects. At the present time, we'll discuss about the client invoice and the tips and tricks to manage your client invoice service. We all know Payment matters are always a bit of an issue when it comes to ending up a deal. One way or another we all work to get a further reward and mostly it is about money. Usually, the system of client invoices is pretty much tuned. However, a certain need for better optimization from time to time pops its head up. To avoid extra stress you might want to look through the information below and get some inspiration on how to improve your invoice arrangements.

Comprehend the importance of an invoice

Invoices are meant to keep track of any business operation having place. This is your legal document that provides you with the  guarantees for the service being paid. At the same time, it backs you up when some financial issue arises from whatever side of the deal. Invoices are valuable when it comes to accounting matters. As an entrepreneur, you must get accustomed to operating them masterfully. 

Get professional design

With all the graphic design apps on the market to find a decent invoice maker will pose no problem at all. Turn to various templates that will arrange all the information required in a fine-looking, professional document. Place your signature, or special brand-stamp, that is recognizable for the client. With the templates chosen, customize other brand qualities - logos, color palettes, fonts etc. for an even more presentable look. Bigger companies have their invoices generated automatically, and they also care for the design.  It might seem as not the most essential part, since not the colors, but money on time matters, however even the design of your invoice is a part of your brand presentation. 

Mind client's requirements

?ompanies are usually overwhelmed with the number of invoices they get to process daily. There are chances that they might ask for a certain format of the invoice you send them. Therefore you might have to adjust your beautiful design with their requirements. This will demonstrate you being considerate of their concerns. Also, it ensures your invoice to be noticed and funded without delays and awkward reminders about your rewards. 

Define the person in charge

When discussing the payment matters make sure to talk to the right person or the right accounting department. You might want to avoid your invoice sent somewhere and get lost in the huddle of gazillion letters sent daily. Double-check right from the start of the negotiation of your services.  The way you are going to get informed about this matter may already tell you how responsibly the company, or the client treats this matter and what words are used specifically. Evasive tone and clear avoidance of the topic will help you think better about whether to get contracted for the job at all.  

Include payment deadlines

Make sure that your invoice contains exact information about the terms when you expect to get your funds. While discussing financial matters before the deal you may already announce your number expectations and how they should be delivered. However, it is never redundant to outline it in your invoice again. With the busy life everyone leads to keep all things in mind is not always a possible matter. The negotiated sum and the time when it is expected are the main figures that your invoice is developed around.

Create an invoice filing organization

It is highly recommended for better optimization and more order to create folders with various invoices sent to your clients. Arrange them by dates, names of the clients, terms of getting paid, those that are unpaid. Having a fine structure developed you will always be able to trace how things are going for you money-wise. This may be deprived of all the romantic flavor since you as the creator should not waste your energy on anything other than art and rewards are just pleasant bonuses...Now, when you have come back to earth, please take care of the filing system and your invoices being in ship-shape order. 

It is OK  to remind about unpaid invoice

When terms are outlined in a crystal clear manner, however, the customer’s side has not respected the commitments it is totally acceptable to send a follow-up email. Hectic business world intends to miss out on some aspects ( not cool, yet inevitable), your reminder will be appreciated and even an apology letter may loom upon the horizon. Other clients feel sad to part with their money, especially when the total amount is quite impressive. Such representatives need an extra push to deliver their end of the deal. Every job done should be rewarded, no excuses here. 

Ask for deposit 

Sometimes, in the matter of precautions, it is recommended that you ask for the deposit. Mostly the payment is delivered when the work is done and meets all the requirements. In order to avoid experiences when such highly-professional work goes unpaid, you may ask for some money paid beforehand. Your clients contacted you to get your services after they have checked through your profiles and your happy clients' testimonials. They know they can trust you in your expertise and follow the deadlines. You know that you can trust them when they freely agree to your deposit terms. Then there is a big chance to get the rest of the payment with no delays and unnecessary reminders.

Thank your clients

In comparison with all the critical matters, invoice-wise thanking might pale a bit. To get gratitude is always a pleasure. Running through hectic days, when everything that you just see are numbers, requests, and reminders, to get a thank you note for a change might make someone's day. Who knows, maybe after you will be placed in the category “Priority payment”.

Take it easy

It does not mean -  let it loose and see what the outcome might be. No, you keep on monitoring the financial side of the work you do. However, do not let yourself  get consumed utterly with accounting, since there is some other job that has to be performed, requiring your full devotion. There is always a way to divide and conquer.

To sum up

Let’s go over again. In order to get paid relatively quickly when invoicing the clients, you have to be ready to commit to creating a professional invoice with crystal-clear information about your services and payment expectations. Be precise, and indeed considerate in the discussions about funding matters. Create a fine filing system in order to be on the safe side always. Do not be afraid to ask for what it's worth, becoming a victim of those who are not used to paying for the services they got. When you are a rookie and gain experience it is quite normal practice to do some job for free, but being an experienced specialist with high-quality services requires money to be paid and exactly when you ask for that.

How To Build the PCB Best - JLCPCB

Hello Professional! Welcome to The Engineering Projects. We hope you are having a productive day. Today we'll talk about the building process of Printed Circuit Board with great efficiency and creativity. It's hard-won to run an industrial company. What’s the reason? One is  the bosses who have earned money quickly expand their business footprint not only focus on PCB,  not delve into how to provide higher-quality PCB and more extreme customer service; also many bosses think more about engaging in financing and listing. How about JLCPCB?Yes, JLCPCB has planted into the PCB with all its heart, just keeping one aim: build the PCB best. JLCPCB was founded in 2006, used to be the leading PCB company, now it is PCB industry big brother, who is highly appreciated and trusted by hardware fields. When JLCPCB makes a mistake, people will say all they know  without reserve. If the proposes will benefit the PCB users, JLCPCB takes act upon it without reserve. All we believe 15 years could build such solid and close relationship between customer and merchants. All suggestions and feedback from customers about production efficiency, PCB quality, customer service and logistics situation will be valued by JLCPCB team. CEO Yuan was also a young electronic engineer before, and spent a lot of time in designing, developing, and testing components, devices and systems in a small PCB factory. Now he has grown up to be JLCPCB leader and is keen on optimizing and developing automatic production lines,  intelligent factory management and brand new SMT assembly methods. He knows how sad it is for an electronic engineer to lack a good and inexpensive PCB board. His regret will not become the regret of a new generation of electronic engineers, so he insists on the PCB industry for more than 20 years, insists on low price but high quality PCBs for customers, and strives for excellence in craftsmanship and customer service. $2 for 5 PCBs, and $7 Start SMT assembly.  Mr. Yuan elucidated, “The profit of the PCB industry is very transparent. Low price, superior quality, fast delivery. The essence is contradictory.” He added, “the only way to solve this contradiction: large production with the fully automated factory.”  Yes, PCBs with high quality, low-cost and quick logistics must reach a certain scale of production to earn profits, 100% true. JLCPCB  fully automated factory is indispensable. So far, it has 5 fully automated factories for 600,000 ? per month, 9 SMT production lines 12-hour fast assembly 35,000,000+ parts monthly. JLCPCB hopes to help engineers and companies to access most economic, best and innovative PCB service. We are trying to meet and exceed loyal users' expectations in price, service and production. Even in 2020, it made these new attempts:

• The SMT production plant was relocated  to an advanced factory, expanding from the previous 32 machines to 72 placement machines.
• expanded from the original 4 SMT production lines to 9 SMT production lines to support more production.
• Parts have increased from 30,000 kinds to more than 80,000 kinds.
• Added black, blue, red  PCB assembly service.

JLCPCB was also encountered many difficulties in Feb. 2020 because of the COVID-19 epidemic, which resulted in a bit longer PCB turnaround time and SMT order production delay. And the lead time has become as fast as before since March,2020. We redistributed the staff, and reorganized the equipment and manpower to make the production line run more and more smoothly. Of course, this is achieved when we ensure that our own employees are sufficient and well paid. That's why we always say methods are more than difficulties. Good products should be used by more people, especially people who desire high-standard  hardware.For foreign customers, the first impression of JLCPCB is "$2 for 5 PCB" which has successfully entered the customers' sight. People may curious about a "comprehensive JLCPCB" besides what they see online:where is the factory of JLCPCB ? What is the factory like? Who are the members of the JLCPCB team? Distance makes obstacles, however how JLCPCB shorten the distance with foreign customers.We would like to customize some small gifts randomly placed in the customer's boxes. As the boxes flow to all corners of the world, people will receive our greetings. Little gifts are always appreciated and collected by the friendly users. For customers JLCPCB is a strong backer , thoughtful and caring. For JLCPCB, they are creative and productive talent.Their hardware projects promote the development of technology and are also changing people's lifestyles and the pattern of the world.

4 Things Every Modern Office Needs

Hey Readers! I welcome you on the board. I hope you are doing Great. are you establishing a new office? or you want creative ideas about your Office? or you just want to get the concepts about the Modern office requirement? then I can help you. Office designs continue to change with modern trends, and there are many aspects of office design that can even have an impact on the productivity of the people who work there.  It is more important than ever that the office environment is a welcoming one to ensure that every staff member will be able to give their best in terms of collaboration and work, and there are a number of things that every modern office needs - everything from spatial design to using LED strip lights. A varied and comfortable workspace Young professionals tend to enjoy a modern open floor plan in the office. Collaboration and communication are important and a modern office needs to promote this. However, there can be too much of a good thing and it is still important that employees have a place in which they are able to concentrate by themselves or within smaller groups. A modern office should provide space for these more intimate activities, or the segment of the workforce that may need quiet in order to get things done could be alienated.  A modern office should provide the space to allow these activities to be undertaken simultaneously, allowing employees to move between activities as required without distracting others.  Appearance and lighting In addition to the way in which a modern office is laid out, how it looks and how it is lit is also of vast importance to employee comfort and productivity.  It is a scientific fact that our mood is dictated by our environment, and colors play a big role in this. The modern office should be painted in a color that has a calming and relaxing effect, and wall accessories and throw pillows can also be made use of to create a positive atmosphere.  Lighting is also of key importance to offices, and the trend in modern offices is to make use of LED strip lights over the more traditional fluorescent lighting. In addition to being more environmentally friendly and cost-effective, LED strip lights have also been shown to be more beneficial to the health of office workers, improving mood and vitality, where mental issues such as stress can be caused by poor lighting.  Access to technology  The modern office needs to be equipped to deal with all aspects of modern technology. Modern offices try to allow employees to work wherever they like, which means they need to be able to gain access to their data wherever they want. This means that a strong Wi-Fi signal needs to be available at every point in the office, with lots of Ethernet ports throughout the environment as well as wireless charging solutions, recessed power outlets in tables and desks, Bluetooth headsets, cordless phones and cords in floors, trays and walls.  Socialization and health A common area or lounge is a good way to help with office socialization. The area needs to be relaxing and away from the main office to allow for conversations without distracting others. Some modern workplaces even provide a gym or wellness room where employees can keep fit, and the pantry should be stocked with healthy snacks.  Workers spend a good deal of their lives in the office, making it essential for the modern office to ensure their health and happiness. A healthy and happy employee is a productive employee.
