Hello everybody,
since this is my first post in this forum, I'd like to introduce myself, first. I am an apprentice for eletronics at a quite large computer company in southern Germany. Eletronics has been a hobby of mine for a year or two, but as the proverb states: The more you know, the more you know that you know nothing.
So I came here to expand my knowledge. I have been quite active at german forums about electronics before, but unfortunately I've had to come to the conclusion, that all members there are either unexperienced by themselves, or extremely arrogant. They're so arrogant, it's impossible to work with them. So I hope I will find polite and benevolent people here, just as I seek to be.
Okay, enough about me, here's my problem: I want to built a music unit for at work (work can be very dull without music, huh?). It should have a small amplifier (2x5 Watt RMS @ 4 Ohms should do) with acceptable quality. It should also have a radio unit integrated (my favourite surplus store does the TDA 1596 and TDA 1574, anybody some experiences with one of those?), of course, it would be cool if I could control this digitally (Atmega?). The next thing is an auxilliary audio in (for my mp3-player), with a stabilized 1,5 VDC out to replace the mp3-player's battery. The whole system should also not draw too much power from the outlet, otherwise I risk that my employer gets mad at me... So the overall system efficiency should be kept at the maximum possible, even if I have to use more expensive parts for that.
I think the biggest problem will be the radio receiver. Has anbody ever done a radio receiver, either with digital or analog controls? Any reports would be appreciated.
Thank you very much.
