Instant communication is critical between the sweet wife and I. That is why I have streached a very fine wire from the house to the workshop, with a tin can attached to each end. When she needs me, she bangs on her can with a spoon, and I can hear it all over the shop. When I yell in the can, she hears me and visa versa. It's worked for years, no batteries to replace and requires no 110 volt power. Kind of basic for a couple of old timers but fool proof.
Now if you believe that, I have a bridge in New York that I will sell you.
Roly, looking for a cell phone for idiots........
