Why EV Pickup Trucks Will Spearhead The Switch To Electric Motors

Hi Guys! Hope you're well today. Glad to have you here. In this post today I'll detail why EV pickup trucks will spearhead the switch to electric motors. In 2019, approximately 63 percent of Americans looking to buy a car were interested in buying an EV, according to Consumer Reports. The stage is set for major EV manufacturers to contend over the market. Of all body styles, pickup trucks seem to be of particular interest to them. General Motors, Tesla, and Ford are doubling down their efforts in EV pickup design. This is all so that models like the Hummer EV and the Cyber truck can release within the next few years. Trucks are favored for their towing power, traversal abilities, and relatively low need for maintenance. Those are perfect attributes for EV platforms to expand upon. Here are the top advantages EV pickups bring that will let them lead the switch to electric vehicles.

Pickups Will Make The Switch To EVs More Palatable

The first and most important reason EV pickups will lead the charge in switching to electric is because they appeal to a wider demographic. At least, that is the case in the United States. The latest data from Hedges & Co. shows that there are almost twice as many pickup owners in America as there are car owners. People from all walks of life find a use for pickup trucks. Hence, capitalizing on pickup trucks will make the switch to electric vehicles more attractive to the common driver. Jessica Caldwell, the auto analyst for Edmunds, says that everyday motorists are the key to bringing the electric dream to fruition, not enthusiasts. They would need to be convinced to change their behaviors to accommodate the differences in operating an electric pickup. But with the benefits that EV engines offer, manufacturers are optimistic that they can be made to see the advantages in making the switch.

Greater Capacity For Customization And Novel Features

With so many Americans expressing interest in EVs, selling EV trucks sounds easy on paper. However, General Motors’ Josh Tavel says that it's not as simple as that. The average Hummer buyer, he says, is not buying the truck to have a lower carbon footprint. The target demographic has always been monster truck and military enthusiasts, says Tavel. It has been this way ever since the vehicle first rose to popularity in the late 90s and early aughts. What they are marketing to are the adventurous and outgoing types. This market, GM says, overlaps significantly with engine-savvy car enthusiasts. If they can be made to adopt the electric engine, they can influence everyone else to do so as well. This is why they added some features they know will appeal to vehicle aficionados. These include novel additions such as a crab walk mechanism and intuitive graphic displays. . All these and more can be easily supported by an EV built from the ground up with efficiency as a focal point.

More Reliability And Power Than Traditional Trucks

Electric pickups could not have come at a more appropriate time. Nowadays, consumers are clamoring for efficiency and reliability. This is mainly out of concern for the environment. On top of this, however, people also want cars that are simpler to maintain and break down less. Current surveys point to a drastic shift from public to private transport soon. More than 78 percent of commuters will mainly rely on private vehicles for transport from now on. This was according to the 2020 EY Mobility Consumer Index. EVs have fewer moving parts. Thus, they are potentially more powerful and consistently reliable than internal combustion vehicles. Reliability is one of the most prized and sought after traits in trucks, according to consumer truck reviews and rankings.

Enhanced Performance For Commercial And Recreational Use

The increased towing power and dependability of EV pickups make them attractive commercial fleet vehicles. The long-range operation of electric trucks is more economical than fossil fuel ones. Headquarters and stop points could be established according to the trucks’ ranges and charging stations set up at these points. This way, refueling can be done overnight at the stops themselves, instead of on the road. A supply line like this can be vastly more efficient in terms of time and energy. As for recreational use, EV pickups can excel at carrying vacationing and camping equipment. This can be of particular appeal to suburbanites, who often vacation by going out into the wilderness to camp and kayak. With a fair number of Tesla owners, they would appreciate being able to do so in an environmentally friendly way as well.  More engine power can allow them to carry more gear, and longer range can let them make better headway before stopping.

Mutual Benefit For Consumers And Manufacturers

Auto manufacturers stand to gain much from the demand for EVs, especially in pickups. This is thanks to their high-profit margins and demand. The average price of a full-sized EV pickup is $50,000. Even so, they are easier to maintain and have better long-term performance. This makes them a more sensible long-term investment. Figuring out the right price point is a major point of emphasis for manufacturers. Ken Morris, vice-president of General Motors’ EV and self-driving vehicle division, voiced his views on this challenge. According to him, the tricky part will be to price the trucks low enough to make them preferable over traditional ones, but not so low that it hurts profit. This has turned out to be rather difficult with the 200-kilowatt-hour batteries that EV pickup specifications demand. These would cost $20,000 per unit, which is slightly more expensive than your average economy vehicle. These factors together make it easier for automakers to fund their R&D projects for better EV tech. Even with a higher mark-up, consumers simply accept this as a matter of course for a young technology. And thus, they buy the vehicle anyway. Although controversial, it certainly facilitates the rapid growth of electric vehicles. This growth will likely go faster from here on out. That's all for today. I hope you find this article helpful.

I suggest you buckle up and read this post all the way through, as in this post I’ll detail the Introduction to LM2576 covering the datasheet, pinout, features, and applications. Let’s jump right in.

Introduction to LM2576

• LM2576 is a voltage regulator, also called a buck converter, mainly used as a pre-regulator in linear regulators.
• It is a simplified version of switching power supplies where it houses all functions needed to step down the circuit voltage.

• This buck converter comes with an integrated switch that drives load under 1A.
• LM2576 is available with remarkable load regulation and load line.

• LM2576 is available in two versions: version with fixed output voltage featuring 3.3V, 5V, 12V, & 15V and version with adjustable output that comes with the ability to choose your desired output.
• It is also known as the DC-to-DC power converter mainly used to step down the voltage from the input supply to its output load. The current is increased during this occurrence of voltage regulation.
• This buck converter comes with a fixed-frequency oscillator of around 52 kHz. It is also available with an in-built frequency compensation method.
• Frequency compensation is used to minimize the oscillation and vibration in the electrical circuit. Resistance-capacitance networks are applied for this frequency method to work.
• Apart from the excellent load and line regulation, this component is available with a manual shutdown option using an external ON/OFF pin.

LM2576 Pinout

The following figure shows the pinout diagram of lm2576.

LM2576 is available with five terminals:

1. ON/OFF: This pin is used to shut down the voltage regulator when the input supply current is decreased to 50uA. The threshold voltage is 1.3V. When the voltage on this pin is set to below the threshold voltage, it will turn on the voltage regulator. When the voltage on this pin goes above the threshold voltage it will turn off the device. And when this pin is connected to the ground or leave it open, it will remove the shutdown feature from the device. Whether you connect this pin to the ground or leave it open, in both cases the regulator remains turned on.
2. VIN: This pin is connected to the bypass capacitor that reduces the voltage transients along with providing the switching current.
3. Output: This terminal behaves like an internal switch where voltage potential goes back and forth between (Vin – Vsat) and -0.5V. The Vout/Vin is this pin duty cycle. The coupling is reduced due to the presence of PCB copper attached to this pin.
4. Ground: This is the ground pin.
5. Feedback: For the feedback loop, this pin defines the regulated output voltage.

1n4734 Zener Diode Datasheet, Pinout, Features & Applications

Hi Folks! I hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n4734.

The 1n4734 is a silicon planner power Zener diode that is employed as a low current voltage regulator. It is incorporated as a shunt regulator in many applications. This Zener diode conducts the current in both directions in contrast to the regular diode that conducts in one direction only i.e. regular diode conducts in forward biased condition only. This Zener diode conducts in both conditions forward biased condition and reverse biased condition. Power dissipation in this Zener diode is 1W and standard Zener voltage tolerance is ±10%.

I suggest you read this entire post till the end, as I’ll detail the complete Introduction to 1n4734 covering datasheet, pinout, main features, and applications. Let’s dive in.

Introduction to 1N4734

• The 1n4734 is a Zener diode employed as a low-current voltage regulator. It is also employed in clipping circuits with high power ratings. This Zener diode is made of semiconductors and is used in voltage protection circuits.

• The current flows from the anode side to the cathode side in the regular diode in a forward-biased condition. On the other hand, in the case of the Zener diode, current conducts in both conditions i.e. forward biased condition and reverse biased condition. Forcing regular diodes to conduct in both conditions will damage the device.
• The Zener diode is normally used in modern electronics and is constructed by plenty of different voltages.

• While picking the Zener diode there are two parameters that you should consider… one is the power dissipation and the other is the power Zener voltage. When a higher reverse voltage is applied to the Zener device it creates the Zener voltage.
• Some Zener diodes experience sharp and highly doped p-n junction when they undergo a Zener effect or Clarence Zener.
• The power dissipation inside the Zener diode is used to identify the amount of current flow. More power dissipation results in more current flow. Power dissipation in this Zener diode is 1W.
• Zener diodes are utilized to generate low-power supply rails using higher voltages. Reference voltages in the electrical circuits are also produced by these Zener diodes.
• In some electrical circuits, there is a limit to the applied voltage. The voltage applied above this limit can damage the device. These Zener diodes are used in those circuits to prevent circuits from overvoltage.

The Best Technologies for Catching Security Flaws in 2020

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the best technologies for catching security flaws in 2020. Security is a key priority for all organizations, and attacks have become increasingly specific. Usually, attackers take advantage of specific bugs or vulnerabilities to gain access to sensitive data. The cost of breaches can be huge, which is why organizations are equipping themselves with the best technologies aimed at catching vulnerabilities and security flaws before a potential hacker can take advantage of them. Let’s take a look at the best technologies being used in 2020.

White Box Testing (SAST)

One of the older technologies that has been around for over 10 years is white box testing. It is commonly referred to as Static Application Security Testing (SAST). This technology is useful for detecting software vulnerabilities early in the software lifecycle. These issues can be detected through their file name and line number. Additionally, it has in-built adherence to coding regulations. There is, however, a tendency for some false negatives and positives to be detected. The technology can also be somewhat complex, which can lead to issues in implementation. They are also not able to find defects outside the application code such as in third-party interfaces. Typically, SAST can find 14% of vulnerabilities within a code. This makes it useful, but it also means that other technologies should be used as a part of a comprehensive security structure.

Black Box Testing (DAST)

A supporting technology that is often used alongside the above testing method, is black-box testing. This is known as Dynamic Application Security Testing (DAST). Some organizations tend to wonder about sast vs dast. In truth, rather than selecting one over the other, it is far better to use them together. DAST can detect security vulnerabilities in running applications. Runtime problems can also be detected with ease. Unlike SAST, the exact line of code is not always able to be located. DAST requires a running application which means they can also be used later in the life cycle. Overall, the dynamic approach allows this technology to detect memory leaks, SQL injections, and many other real work vulnerabilities. It is helpful to use it before an application goes live.

Interactive Application Security Testing (IAST)

Both DAST and SAST have been around for a while. They are still reliable, but they shouldn’t be thought of as complete solutions for dealing with ever-evolving modern threats. IAST is a newer technology aimed to plug these gaps and to provide a more comprehensive security solution. This technology works through the placement of an agent directly within an application. It can scan the entirety of the code within an application which makes it very useful for catching all types of security flaws and vulnerabilities.

Runtime Application Security Protection (RASP)

Similar technology to IAST is RunTime Application Security Protection.  Instead of directly testing, it acts as a potent security technology that is effective at keeping threats out. It is placed within an application and allows consistent security checks to be conducted. Protection can be gained even when specific vulnerabilities are exposed. This makes it a fantastic technology to use in addition to other security solutions. It is even capable of responding to and neutralizing any live attacks. Security teams, however, should not solely rely on RASP. Instead, they should remember that even if attacks are prevented, the underlying flaws would still require a fix.

Reducing False Positives

No technology is completely infallible, and false positives are to be expected due to a variety of factors. Generally, there is a way to significantly reduce the number of false positives picked up by these technologies. This can be achieved through the use of abstract interpretation algorithms. For the best results, they should be specifically tailored to the application domain.

Challenges of Combining Tools

One type of tool isn’t enough to provide full security, and therefore a variety of solutions should be implemented. Know that combining tools isn’t always easy, and there are certain considerations to take into account. One specific challenge comes from the fact that each tool will have different naming conventions and severity ratings. This can cause issues when you look to rank vulnerabilities and decide on the best course of action. In this instance, it is worth using cross-referencing tools to determine the threats to your application. It is well worth the extra time and effort involved in utilizing these tools since a security breach can be incredibly costly. Organizations are becoming far more aware of these threats in 2020, and this has led to an increased usage of all of these various security technologies.

Summary

Overall, there is no technology better than the other. Rather, it depends on how they are used, and many are more effective when used together. Getting these combinations correct and utilizing the latest technologies should be a key security priority for all organizations. That’s all for today. Hope you find this article useful.

7 Most Commonly used Types of PCB (Printed Circuit Board)

Hello everyone, how are you doing and I hope everybody is doing great.  i am going to discuss today the Types of PCB (Printed Circuit Board). Thank you, everyone, for coming back to our website and it means so much. we are grateful for your engagement and most importantly for choosing to educate yourself over anything else in the world.

PCB circuit boards are everywhere and we daily use dozens of circuit boards and interact with them. There is no doubt in saying that the PCB has made our lives easier and advanced. For example, the first thing in the morning your alarm goes off, and wherever you hit snooze, every time you send a signal through its circuit board.  And probably the list goes on as you turn the light on off etc.

Let's begin!

What is PCB

The abbreviation of the Printed circuit board is PCB, and it is the core of electronic products. But all of them are not equal. They are available in different types and made from different materials and specifications for a wide range of applications. Since the early 1900 PCBs are manufacturing and there is a major evolution of PCB happened in the last few years. PCB is a board that interconnects different electronic and electrical components. It is necessary for building a circuit. This article will bring a deeper understanding of the types of the circuit board and help you in finding the most suitable PCB for your needs. If you are working on some electronics project and want to design or fabricate PCB / PCBA, then we would suggest you to try PCBWay Fabrication House. They have an experienced team, eager to guide you throughout the process. & they always provide excellent results as per your requirements.

Different Types of Circuit board

• As I mention before that printed circuit board comes in a different size because of their characteristics and different requirements.
• The copper rails on circuit boards are used to connect different points of locations. They are easy to recognise.
• Their design makes them different from each circuit.
• Most of the PCBs are made of fibreglass, composite epoxy, and other composite materials.
• For simple electronics most of the time only one or single layer PCB use. But for the sophisticated or complex one such as motherboards and computer graphics card multi-layers PCBs used.

Now let's find about the types of circuit boards in details.

Single Sided PCBs

A single-sided circuit board is the simplest one and made out after a different process. Let's find out.

• It is the least complicated one.
• Contain one layer of substrate or base material
• One layer of the substrate is covered with the thin layer of metal or copper (it is excellent conductor)
• After the copper base painting usually a protective solder mask is applied.
• A silkscreen coat is applied to complete the look

Since the circuit board is single sided, it is easy to design and manufacture. All of the components are located on one side of the board. They can be purchased on low cost and especially for high volume orders. Their cost is low as compared to other circuit boards. They are used in a variety of applications like cameras, radio, printers, calculator etc.

Double Sided PCBs

Double Sided Printed circuit boards are more common as compare to single sided PCBs. Because of their high properties.

• Both sides have metal conductive layers and parts are connected to both sides
• Electric components are separated evenly on the entire board
• Holes are drilled through the board to connect to the other side too.
• For connecting both sides used through holes or with the surface-mount.

What is Through Hole

Through holes in double-sided PCBs means that small wires (known as leads) are fed through the holes with each end of the leads and then joined to the right component.

What is Surface Mount

In the surface mount wires are not used as connectors. Alternatively, small leads are soldered directly to the board. Simply put, that board itself is used as a wiring surface for the many components.

• Less space
• Allowing the board to complete more function by freeing up space
• Lighter weight and higher speed than through hole

Double-sided PCBs are used in complex applications as comper to single sided PCBs. It demands a medium level of complexity. The applications that used double sided or double layers PCBs are power supplies, HVAC systems, LED lighting and Vending machines etc.

Multi Layers PCBs

The Multi Layers PCBs are more complex than double sided PCBs. It consists of a series of three or more double layers.  These are using advanced technology in double sided boards.

• More than two layers of the substrate on the board
• The insulating material used on every layer
• The same latest technology of double sided is used to connect the different components
• The largest multilayer PCB was fifty layers thick.

All the applications that are using multi layers PCBs are data storage, file servers, satellite etc.

Rigid PCBs

Rigid Circuit boards are made of the solid substrate like printed circuit boards. Printed circuit board are not just classified based on layers and sides.

• It prevents the board from twisting.
• A most common example is a rigid motherboard
• The main difference is the number of layers
• Rigid PCBs consist of different rigidity

Rigid PCBs can be simple to multi-layers of PCBS. These PCBs can be used everywhere where it needs for PCB.  This type of circuit board is solid and inflexible. Fibreglass is one of the best options because it keeps the board from bending and stops any type of damage.

Flex PCBs

Flex is a short form of flexible. You can guess it with a name that it will make the flexible PCBs with the flexible plastic.

• Fit into different shapes
• Bend the board anytime and keep it safe
• Costly than other designs
• PCBs are light in weight and used in advanced technology

 

Rigid-Flex PCBs

As shows in name that it is the combination of rigid and flex. It is the last type a litle bit confusing but the main concept behind it was to use it with the strongest boards.

• Bothe flexibe and rigid
• Circuit board is rigid but its connect layers with the flex circuit board
• Difficult to make
• Consist of multi layers of flexible PCBs

It have many advantages of using over flex and rigid PCBs. These are found in cell phone applications, digital cameras and automobile etc.

1N5819 Schottky Diode Datasheet, Pinout, Features & Applications

Hello Friends! Happy to see you around. Thank you for clicking this read. In this post today, I’ll document the Introduction to 1n5819. The 1n5819 is a Schottky diode, also called hot-carrier diode, employed for extremely fast switching. This diode is formed when the metal material is combined with the semiconductor material. This combination results in the formation of a barrier that blocks the flow of electrons. The reason this is also called a hot-carrier diode. I suggest you read this post all the way through, as I’ll walk you through the complete introduction to 1n5819 covering datasheet, pinout, features, equivalents, and applications. Let’s get started.

Introduction to 1N5819

• The 1n5819 is a Schottky diode used for fast switching applications.
• With high switching speed and low forward drop voltage, this device is employed in high-frequency applications like DC-DC inverters.

• This diode features low electronic energy in an unbiased condition that is responsible for the creation of a barrier inside the diode that in return blocks the movement of electrons. The formation of a barrier is the reason these Schottky diode devices are also known as a hot-carrier diode.

• The regular diodes and Schottky diodes are similar devices in terms of the current flow. Both favor the movement of current in one direction only i.e. from the anode terminal to the cathode terminal.

IRF840 MOSFET Datasheet, Pinout, Features, Equivalent & Applications

Hi Fellas! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to IRF840.

The IRF840 is an n-channel power MOSFET. It is a fast switching and high voltage device that is available with low on-state resistance. As this is an n-channel MOSFET here conduction process is exercised by the movements of the electrons. In other words, though conduction is carried out by both the movement of holes and electrons, electrons are major carriers in this case.

I suggest you read this entire post till the end as I’ll discuss the complete Introduction to IRF840 covering datasheet, pinout, features, equivalent, and applications. Let’s jump right in.

Introduction to IRF840

• The IRF840 is an n-channel power MOSFET that supports loads up to 8A and 500V. It is a fast-switching and high-voltage device that requires 10V across the gate terminal to initiate the conduction process.
• This IRF840 MOSFET is a three-terminal device made of gate (G) drain (D) and source (S) terminals. The external circuits are connected with these MOSFETs through these terminals.

• This is an N-channel MOSFET, here the conduction process is exercised by the flow of electrons in contrast to the P-channel MOSFET where the conduction process is carried out by the flow of holes.
• It is important to note that conduction is a process that is carried out inside MOSFET by the movements of both electrons and holes but electrons are major carriers in the n-channel MOSFET devices while holes are major carriers in the p-channel MOSFET devices.

• The MOSFET stands for Metal Oxide Silicon Field Effect Transistor. It is also known as the IGFET Insulated Gate Field Effect Transistor. It is made by the controlled oxidation of a silicon semiconductor material.
• MOSFETs and BJTs (bipolar junction transistors) are considered as different semiconductors as BJT is a current-controlled device while the MOSFET is a voltage-controlled device.
• The voltage applied at the gate terminal usually is directly related to the current between the source and drain terminals. The gate terminal voltage controls the current at the drain and source terminals. Simply put, the gate terminal acts like a control valve that controls the current between two terminals.

Hi Guys! I hope you’re doing well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n5818.

The 1n5818 is a Schottky diode. It is also known as a hot-carrier diode that is employed for extremely fast switching applications. It carries high forward surge capability and low forward drop voltage, making it a suitable pick for high-frequency applications. It is available in the DO-201AD package and comes with very small conduction losses.

I recommend you buckle up as I’ll discuss the complete introduction to 1n5818 covering the datasheet, pinout, features, and applications. Without further ado, let’s get started.

Introduction to 1N5818

• The 1n5818 is a Schottky diode that is incorporated in extremely fast switching applications. It is also known as a hot-carrier diode.
• It is available in the DO-201AD package and comes with low forward drop voltage and high forward surge capability.

• MOSFETs semiconductors are the appropriate alternatives to these Schottky diodes and where less power dissipation is needed, MOSFETs replace these Schottky diodes.
• Low electronic energy in an unbiased condition is responsible for the formation of a barrier on these Schottky diodes that restricts the movement of electrons. This barrier formation is the main reason these diodes devise are also named hot-carrier diodes.
• Know that… generally, both the Schottky diode and regular diode are the same devices in terms of the current flow i.e. both devices support the conduction process in one direction only and restrict it in the opposite direction. And current flows from the anode pin to the cathode pin.
• These devices, however, stand different in terms of the voltage required to power up these devices. Both components receive 2V DC source voltage out of which the Schottky diode requires only 0.3V leaving behind 1.7V to power up the diode devices. And regular diode requires only 0.7V, leaving behind only a 1.3 potential difference to power up the component.

• The 1n5818 is made by the mixture of metal with the semiconductor material which results in the creation of a barrier.
• When metals like platinum, tungsten, chromium, and molybdenum are joined with the n-type semiconductor material, they create a Schottky diode. The n-type semiconductor is the semiconductor material where electrons work as major carriers and holes work as minority carriers.
