Are there any real consequences resulting from feeding 12 to 20V continously to an arduino board?
recommended is 7V to 12V
limts are 6V to 20V

Yes it depends on the actual board you have but most boards have capacitors on the regulator with a 16V rating so the capacitors would explode if you fed them with 20V.
Also regulating down to 5V from 20V means a lot more heat is generated and the regulators would overheat and burn.
Look up DC DC Buck Converter Adjustable. You can turn a screw to set output V with some tiny ripple, can be filtered.
Cheap units cost $2+ and can output 3A. A 12V 1A input can output more than 2A 5V, efficiency is > 90%. To convert more current takes more expensive components, the cost goes up but you get a lot of kick for the buck.
thanks guys!
about buck converters, yes you are very right! as a matter of fact I have some lying around, but didnt think of them.
