hi all

[lightbringer81]

first of all i would like to say hi to all of you and i have a big question which makes me crazy

i 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 me any advise would help ...

thank you

Please choose your religion first - analog or digital, or enter the small sect of people wo care about both

Is there some "project" you intend to do ?

Recommendations:

Learn to fix stuff from the scrap heap
Read, read and read
make and modify kits from one of the usual kit vendors

Greetings

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 right

i 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

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,

[lightbringer81]

im not that noob at all i crack opened dozens of adapters and things and i also built myself 30 volt 3 amp power supply now i am trying to make a MOSFET touch sensor and an ac power supply

[lightbringer81]

anymore advice ?

[Rerouter]

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 resource http://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,

thanks for that website that's useful

and what can i do to get into digital electronics ?

and do i need to buy any other equipment for my future work ?
