Your experience is not that unusual for a beginner. Electronics is not something anyone can expect to become profcient in overnight.Well, first of all thanx for your care. Now, I bought a ta7642, this inductor and this capacitor. I made the circuit in the ta7642 datasheet with the fat inductor and with an lm386 output but nothing! Seriously, i dont know what is going on here. Even typical things dont work if I made them.
In overnight? Seriously? I have read a lot of books about electronics (I can tell you a few if you want) but 99% when I am trying to implement something complicated in real life ALWAYS something goes wrong. Something that my precious books ALWAYS ignore for the sake of an easier explanation and an easier exercise but in the end they forget to proceed in the real life implementation of the theory.Your experience is not that unusual for a beginner.

One point to note is that your difficulty with a particular type of circuit does not necessarily mean that such circuits never work. It is true that some circuits you come across may have errors, something that may be more of an issue on the Internet, where material can be copied easily but might not always be verified.
Another stumbling-block can be a repeated mistake of your own, or even a defective part re-used from one project to another. For instance, as a youngster, I got was given a pair of headphones for use with a crystal set, but I could not hear anything with them. Later I found out that although working, they had very poor sensitivity.
Some time later I got a much better earphone which was much more sensitive, and I was finally able to get results. That was quite some moment in my life! Moral: don't give up, but be willing to re-examine what you are doing and try again.
I'm sorry to hear that you are finding this so frustrating. Perhaps it might help to think about some of the reasons that might be behind the difficulty.

OMG I LIKE DAT KAT!!!!!!!!!!!!!! I USED TO HAVE THE SAME LOOKING KAT IN MY LASER LAB.Hello,
Can you post a photo of the inductor?
It is possible thet it has two coils.
One main coil and a coupling coil.

1) The thing is I am a computer engineering student and, yes, I am studying electronics for the sake of an academic future. As you can easily guess, all the books I have read were from my university's library.I'm sorry to hear that you are finding this so frustrating. Perhaps it might help to think about some of the reasons that might be behind the difficulty. I can think of several possibilities:
*Or maybe they have built up related experience early in life, as may some children who grow up with a strong interest in things mechanical and electrical. Perhaps sorting out the nature/nurture argument is best left to the psychologists.
- The books you have are less suitable for somebody trying to learn electronics as a practical hobby, as opposed to studying the subject as part of an academic course. Alternatively, the books simply may not be particularly good ones. In this case, the answer may be to get some better / more suitable books. Other forum members may may be better placed than me to advise you on that, as the books I know about are probably out of date.
- All books and all theory are bunkum, and it is impossible to have success with electronics. This may be what you are tempted to believe, but it is clearly wrong: other people have succeeded, including some quite young children, at least with adult supervision. The crystal radio has been quite a popular project with scouting groups.
- You may be in need of some instruction from somebody who knows the subject, as opposed to trying to read it up for yourself. This would be my guess, particularly in the areas of the practical skills required to build a project successfully, and also in the application of theory, as opposed to being able to repeat it parrot-fashion as a set of disconnected facts. This seems to come fairly easily to some people* but others seem to need to work at it more.
Yes. I agree with that!Moral: don't give up, but be willing to re-examine what you are doing and try again.
