Do you mean that some circuits in google images doesn't work? Or it is not sure if they work?

Yes, that's a fact.

 

Hi,
The way I read your item no20 .I believed you understand the basic electronics components.
What I understood to your request at the start is how to translate the schematics circuitry to a Pcb board.
Most of the comments i read they want you to go to education. For me ,i suggest like this..
By looking each component in a schematic circuit one at a time, look that literal a physical actual component
in your hand. Positioning it as connected in the the drawing .By that you can imagine the connections.
Now you layout a drawing by handwriting to the top of the pcb (not yet etched by ferric chloride).
By then you can assemble this small circuit. Once you did it ,next step is etching process.

Aaaa that why when I tried to make an LED flasher with 7402 it didn't works!

Ooooooo nice tip!! I didn't knew that schematics could read with this way too!! Thanks! And all about education all they have the right! I read and read very carefully until understand how this item e.g. transistor works! Because if no education there is no knowledge! But I still need to learn the data sheets, for transistor and for ICs, because there is some words that I don't understand clearly! Like saturation current, hFe, etc (the most of them I know)
