I was wondering how i could change 12v DC (car cigarette lighter voltage) to 9v 100mah. I have a mini headphone amp(made from the circuit board of computer speaker) and it uses a 9v 100 mah adapter but i wanted to make it portable so i am using 2 9v batteries and it works just fine. I also wanted to be able to plug it into a cigarette lighter(as not to waste batteries). I have very little knowledge in electronics, so please...speak ENGLISH. Just tell me how to connect the capacitors, transistors, or whatever i need to use. dont show me one of those diagrams as i have no idea how to read it.
i would also appreciate it if you could show me a key of what the parts in the diagrams mean and how to read it soo i could use it for future reference.
Thanx and sorry for my ignorance
