seguine@girtab.usc.edu (Christopher Seguine) (04/14/91)

 I'm basically an artist/software person..... Anyway I need some hardware
help.... I have this thing....it could be anything... but in this case its
a video receiver (normal use is like to watch movies on a tv in a different
room than your vcr....its wirelss) anyway my problem is that it runs
on AC... 9V... and i need it to be portable... So how can I make it
run on DC... a battery of some sort.... Is this Possible??? 
 Basiccally I got this thing that plugs into the wall and I want to plug it
into a battery... 
  Any help would be appreciated.... Thanx!
