Since I have a DC adaptor lying around, thought of using it instead. Since I am modifying it, might as well implement some kind of protection just in case I reversed the porality accidentally.

BAD idea.  A reversed input will be shorted through the diode.


Use a relay, with it's contacts between the PS input and the rest.
Connect a diode in series with the coil, to the input power so that correct polarity pulls in the coil and connects the PS and the rest.
