seems tutorial is good. but u did not specify part name. and no pcb layout. a diagram needed and part name also. and specifications. can i use 12 volt battery? car battery? u did not specify anything.
rahil, the connections are pretty simple, u don’t need a pcb layout for that. as far as the parts are concerned, there’s only 1 ic used, that is 7804. its a voltage regulator. a mobile phone requires 5v and the battery used here is of 9v, which is why 7804 is used. so, the moral of the story, you can use 12 volt battery.
