More Electronics Design And Circuit Diagrams Making Electronics Magazine More Popular

In daily life we use different kinds of gadgets that make our life easier and better secured. Most of these products are based upon electronics technology. If we go for buying these products, we may expect heavy investment. However, there are certain electronics magazines or online electronics portals that provide all the information so that you could design and develop these gadgets by self. Display of electronics design and circuit diagrams make the understanding of any device easy and fun filled activity.

Recently I went through an electronics magazine having print and online versions. The write ups about Door lock controller and Driveway Alarm are very much convincing. The presence of such write ups show that how much useful these electronics magazine are for common man. Here is the importance information about both the devices that can be used in house or at office place to feel better secured.

Door Lock Controller

Door lock controller may be utilized to run an electromagnetic door lock or an electric strike. A little electromagnetic strike opens the door. The door lock controller presented here is an easy electronic switching circuit. Its electronics design uses a low-priced unipolar Hall Effect sensor IC MH183. This CMOS switch IC incorporates advanced chop stabilization technology to give exact and stable magnetic switch points. The design, performance and specifications are optimized for solid-state switching function. The internal output transistor is switched on in presence of adequately strong south-pole magnetic field. Likewise, the output is switched off through the presence of a weaker south field. After the sensor switch detects a powerful south-pole magnetic area in its vicinity, the remaining circuit is switched on for about TEN seconds. This delay maybe adjusted. After the correct sequence of triggers is applied, the electromagnetic door lock gets operational.

Driveway Alarm

You may install Driveway Alarm inside a driveway to detect a person, vehicle or big animal. It sounds an alarm when any interruption takes place. Circuit diagram contains 2 modules: receiver and transmitter. The laser pointer is powered via the 9V DC supply available from the receiver module. Installation of receiver and transmitter modules is detailed in separate layout. Working of receiver module is very easy. In the beginning, when power is applied to the system, it is in standby mode. Once the laser beam is interrupted by an object, person or animal, the photo-sensor energizes the rest of the circuit to buzzer the sounds.

A specific section named circuit lab is especially dedicated to electronics design and circuit diagrams of commonly used devices and this feature further enhances the importance of online electronics magazines.

Electronic Embedded System Design – Important Feature Of Online Electronics Magazines

The world of electronics is witnessing a revolution in the way products are conceived, designed and implemented. The ever growing importance of the web, the advent of microprocessors of great computational power, the explosion of wireless communication, the development of new generations of integrated sensors and actuators are changing the world in which we live to perform. The online electronic magazines provide every information about the ongoing trends that take place in the designs of electronics including those in Electronic embedded system design. One well designed and planned magazine that I like much is Electronics For You; it provides every possible knowledge about ongoing trends in electronic designs. It is a boon for all those associated with electronics trade.

Electronic embedded system design is a routine segment of this online electronics magazine. The overall goal of electronic embedded system design is to balance production costs with development time and cost in view of performance and functionality considerations. Manufacturing cost depends mainly on the hardware components of the product. Minimizing production cost is the result of a balance between competing criteria. If one considers an integrated circuit implementation, the size of the chip is an important factor in determining production cost. Minimizing the size of the chip implies tailoring the hardware architecture to the functionality of the product.

As the complexity of the products under design increases, the development efforts increase dramatically. At the same time, the market dynamics for electronics systems push for shorter and shorter development times. It will be soon imperative to keep to a strict design time budget, no matter how complex the design problem, with as little as six months from initial specification to a final and correct implementation. To keep these efforts in check and at the same time meet the design time requirements a design methodology that favors reuse and early error detection is essential. We expect the majority of high volume platforms developed to be programmable either at the logic/interconnect level (e.g. via FPGA) or using software.

Both reuse and early error detection imply that the design activity must be defined well, so that all phases are clearly identified and appropriate checks are enforced. To be effective, Electronic embedded system design methodology that addresses complex systems must start at high levels of abstraction. The professionals of most companies, engaged in Electronic embedded system designs and IC design, are familiar with working at levels of abstraction that are too close to implementation.

It is must to know the latest updates in Electronic embedded system design practices to keep the production cost and the product cost bare minimum; and efy like electronics web-portals may be the good source to get all the information within seconds.

Silicon Wafers Are Used In Electronics

Silicon wafers are semiconductor devices used in many electronics today. Even though they sound like a snack, they have a very important job. They are used in making computer chips by many manufacturers. These tiny little wafers have a big job. You cannot find any electronic device anymore that does not contain one of these.

Silicon is a conductor of electricity. When altered it cannot only conduct electricity but can also be used as an insulator. The amazing thing about these wafers is that the main ingredient in them is none other than beach sand. We all know that sand acts as a conductor for lightening but that technology is also used in computer and electronic circuit boards.

The sand used to grow the wafers is monitored very closely. The sand must be kept clean and free of debris. If the process is contaminated, it can make for a faulty connection. Growing silicon wafers is done in a strictly regulated environment and handled with great care by experienced technicians.

During the thin film manufacturing process, wafers are produced in a variety of sizes and specifications. Composition includes many different things before fabrication is complete. They are then handled with care and packaged for distribution.

Wafers are cleaned with a special compound to make sure their consistency is not altered in any way. This cleaner is a weak acid so as to remove any kind of impurities or to take care of any issues caused during the sawing process. The sawing process is used to make sure they are the appropriate size needed for the application.

The different sizes are for different applications but is determined by the mechanical strength of the components. Although sizes vary, wafers are generally manufactured between 100mm and 300mm in diameter. That makes for a very tiny, yet very important piece. These parts vary in price and are dependent on size and usage.

The machinery used to manufacture these parts can cost as much as a small factory. For such a little thing, the expense is great but when they are so necessary in electronics there is no way around making them and making them correctly. Generally they are made of silicon for electronics applications, but other materials are being employed as well.

These little pieces are used in many different electronics in the world of today. Computers being the obvious but others include cell phones as well as any digital appliances. Silicon wafers are a main component in anything digital. With the conductor insulation aspect of the device a wafer must be used. They are revolutionizing the world of electronics as we know it.

The silicon wafer is also commonly referred to as an IC, chip or microchip. We see commercials everyday for microchips, computer chips and processors without even realizing what these little microdevices are. Consumers are only interested in the end device, but you should know that the silicon wafer is one of the most common, most necessary building blocks to almost any electronic device you own.

Just think, this tiny and in today’s world necessary device was discovered by accident it has changed the world of electronics as we know it.
