When I was a kid, my dad brought home a thousand foot spool of wire
from the scrap where he worked, and had some old telephone stuff lying
around, and I remember stringing a pair to the house across the way,
and getting a working intercom (we never tried to make the ringers
work) with a battery and a resistor...

=============================================================== From: wes ------------------------------------------------------ if you use cordless phones, you don't need to do all the fancy battery and resistor stuff. just the crossover is needed. the base stations still need power, of course. this may be less fun, but the voice quality is the same as if you were on a real phone call with a really good connection. I used these as walkie-talkies in all sorts of interesting situations before cell phones became affordable. -wes
