    Hello all
    I am an electronics engineer and my doubt here is in my under graduate i was learning all about electronics theoritically , but now i need to know things practically by designing some hardware models how can i start this?? what are the things i need? And what are the books i need to refer? It would be great if any one helps.....
    Thanks in advance
    I

    In my experience, theory was the requirement for design.
    You could look at places like Talking Electronics but it is more theory with practical building circuits if the latter is what you mean you need.

    If you are currently employed in an area using electronics design, the best thing you could do is find a mentor to direct you. I was very fortunate to have a mentor when I started my career, a fellow employee super-technician who did engineering design without a college degree. His most important advice to me was to continue my part-time studies and get an engineering degree. It took ten long years, in the meantime raising four children and providing an income for my family, but I stuck with it. In addition to my formal studies, I had the opportunity to work as a technician in a well-equipped electronics laboratory. I also had an electronics workbench at home, but the difference between hobby electronics and commercial electronics equipment is huge. I eventually did most of my "hobby" work after-hours at my employer.

    Still, I would strongly recommend that you start a home electronics laboratory if you have not done so yet. Begin small and purchase test equipment as you can afford it. The best test equipment is whatever works for you, not the most expensive. There are many bargains on both new and used test equipment to be found on the Internet, but you need to be careful that what you purchase actually works as described by the seller. A warranty-return capability is desirable, whether for replacement or a refund. Some sellers sell equipment "as is" and do not accept returns for replacement or refund. Beware of such sellers.

    There is a minimum of equipment you need to get started: a multimeter, a soldering iron and good rosin-core electronics solder (lead/tin 60/40 if you can find it), long-nose or needle-nose pliers, diagonal cutters, screw drivers, nut drivers and small wrenches, a good light for the workbench, a magnifying headset... and components. I started out as a young boy taking apart discarded television sets to salvage parts. I still salvage parts, but the electronics have changed. You need to decide what course you will pursue in a career before choosing a set of home tools and components. In other words: set a goal. As you become older and more experienced, modify your goal as needed to accommodate your interests and circumstances. Read the trade journals and published papers appropriate to your field. Join engineering societies and participate in their activities. Visit libraries and borrow technical books to study at home. Your education did not end with graduation. The purpose of college was to teach you how to learn. A secondary benefit occurs only if you actually learn something.

    So, tell us what you want to DO with your life. Maybe someone here can point you in the right direction.

    You should just become a hobbyist like me. I have no trouble putting together circuits without knowing what I am doing. :)

    You also need decide at some point if you just want to stay with digital/analogue logic etc or micro processor.
    But for now there is many little projects out there based around the 555 ic, such as a simple PWM DC motor controller, parts can be had off the internet, but I suggest you use someone like Digikey if you are in N.A.
    not only do they have reliable original manuf parts but every search will also provide a PDF of the item.
    There is also a Triac controller for your router etc for AC based circuits.

    Power supplies are a good place to start since later projects will require a power source of some kind. A breadboard is a good start, building circuits on a breadboard powered by a power supply.

    5 Volt power supply, about 300 mA or so is good.
    +12 and -12 V power supply for op amp circuits, 100 mA or so.
    Adjustable voltage sources are handy for learning about components. These can be as simple as a pot and an op amp, maybe a transistor buffer on the output.
    If interested in any of these I can supply circuit examples.

    PDF file okay? Design 629. + and - 12 V with two variable voltage sources. As a simpler option you can just use + and - 12 V in batteries. This gives you a suitable + and - V for op amp exercises and a variable +V to - V at 100 mA or more for other exercises.
    Do you have a breadboard and multimeter?

    Good start. How are you set up for power sources? How are you set up for components? Where do you normally buy parts from? I will see if we can stay coordinated on these things.
    Me? I am a retired tech school teacher. I, literally, have hundreds of wall wart power supplies for projects and a school's worth of components at my disposal.

    I'll get components from electronics street here in local...so as a first step i will try the design which you sent me today....

    It would help me specify parts if I knew what you had available. Local is good. Are you in Seoul? Electronics Market? Great place. Everything available at good prices there.

    I don't know what stuff is available in India. We will find out as we go along.
    Do you have any specific interests in mind for circuits. Analog? Digital? Microprocessor? Practical circuits? Educational circuits?
    Let's start with some classroom basics and see if they fit your expectations.
    Diode exercise. Get to know the basic characteristics of diodes.

    Too simple?

    Bipolar junction transistors. NPN to start.
