[Noisebridge-discuss] 83c network up and running

[jim]

   generally not in the case of the usual wall 
wart: positive is on the outside (i know there 
are exceptions, i haven't encountered them). 
   for most devices, both signal and power 
connectors have their external connection as 
negative, often tied to the neutral of the 
house AC or to the house AC ground lug (more 
or less the same thing as far as most 
electrons care). 
   there's probably some good design reason 
opposite orientation in wall warts. 
   i am often mistaken.
