power supplies

[Joel Jaeggli]

If you carry 3.3volts for any significant distance you'll have a 
substantial voltage drop the ammount of courrent you can will quickly 
result in larger conductors...

you can get nebs compliant -48volt dc atx power supplies, then just use 
use a hanging huge rectifier (or two) to power the whole stack. but then 
you have the joy of working with large amounts of dc power...

  In Dr. Johnson's famous dictionary patriotism is defined as the last
  resort of the scoundrel.  With all due respect to an enlightened but
  inferior lexicographer I beg to submit that it is the first.
