I was looking at doing some chip design lately and as far as I could tell the process I was looking at could allow you to make a chip that would take anything from 2.5v DC (any polarity) to 250V ac as an input and provide 5V DC at 1amp for about 30p in mass production! I say 'as far as I could tell' cos they wanted £40K upfront for access to the real details... and no manufacturer would buy something that would make their product semi-eternal!On Thu, 07 Nov 2013 17:10:20 +0000 Tom <madtom1999@xxxxxxxxxxxxxx> wrote: Hello Tom,That is an international standardAh, standards. I love 'em; So many to choose from. ;-) In the early days of such things, as often as not, the +ve would be on the outer part. That never made sense to me. Admittedly, at 5V any harm to either person or equipment would most likely be minimal, but there's always a risk.
