Wayne told us how to make a telephone EIS generator. Telephone cord with  
one end cut off and alligator clip connectors. Connect the clips to your  
electrodes, plug it in. Sounds good so I made one. My wife refused to allow me  
to use it. I still have it somewhere just in case my wife takes a trip 
alone, or  we loose power and the phone line still works.
