content: first of all i would like to say hi to all of you and i have a big question which makes me crazyi like electronics , tearing devices apart > trying to rebuild them etc i read lots of book about electronics and i think i have basic theoretical knowledge about electronics like circuit components ohm's law etc but i cant find anything to use these and i need some practical knowledge i have a small set of equipment which is 3 multimeter , soldering iron , parts which i desolder from old devices but i cant go further than buying pcb with components included and just solder and run them thats where i need you more-experienced people than meany advise would help ...thank you

content: if you mean digital programming PIC and arduino things im not interested in that at all but if i could run both i would love to learn both but i say said i prefer analog if i understand analog-digital thing righti do the reading part but i heard i cant get old things from dumpster because companies get these for money to recycle them (please correct me if i am wrong)and thanks for advice i would try to modify things

content: if you want to start with analog, practical, take an old power brick (plugpack as some people term them) one of the AC-DC ones that you will never use again and crack it open, what is inside is an intro lesson to linear power supplies,

content: now a starting point like that would be a good reference point for your first post, now i have some idea where you are lets ramp it up a bit,for practical minded theroy, this is a good resourcehttp://www.allaboutcircuits.com/as for something to play with to learn, perhaps add current limiting to your power supply, depending on how deep you want to look, that can teach you a large amount about op amps and resistors,
