How can I make a 9V 1A power supply? Answered
I need a 9V 1A power supply for my Macintosh portable because the battery has died. I am fairly new at electronics and soddering so pictures of the actual power supply being made and not just the technical drawings would be extremely helpful. Or if you know of a cheap place where I can get a new Macintosh portable battery or a cheap replacement battery that would wrk as well. Thank you in advance.
