I've really been having a lot of fun learning and playing with electronics and my atmega8/16s. While I feel good enough to call myself a newbie now I'm curious what components do you guys use most often?
I'm getting some atmega168 cause I want to make 3.3V circuits as well as some other components. I would like to get as many useful general/cheap parts if possible.
Last time I got 100 .1uF decoupling caps, and 100uF electrolytic caps both which I plan on using on many other projects and we great investments for large (for me) quantities.
I've learned when its ok to use these general sizes and when I need to go get a specific cap but that is not the case for coils/inductors. What are general inductor sizes you would recommend? What about diodes? Are these parts all to specific?
I know in industry you find the part that meets your minimum requirements because its usually the cheapest in large lots. In my case I don't mind paying bit more for more general parts in small lots.
I'm sure there are other newbies here who wouldn't mind knowing what components are good to have once we are feeling comfortable with electronics?
Could I also get some comments on this voltage regulator circuit?
Must the caps C1 & C3 be tantalum, or can the be electrolytic?
Could I replace C3 with a 100uF cap?
Could I replace Cc with a .1uF cap?
Like I said I don't know coils that well but can any other value be used with L1? (any comments on this would be appreciated)
