The house we bought recently is old and has been having work done, in the course of this work the doorbells for both units got hosed. I have found all the parts, but the wiring is a nightmare knob and tube reused, new stuff spliced in when wires were relocated etc.
My fox and hound set was a causualty of the move, I'm sure it will turn up someday, but I need to get the doorbells going ASAP. Being that we have a large and varied geek collective at the HF, I'm guessing one or more folks might have a set I could barrow?
Let me know if you do, this is to be used only on dead wires to verify and trace, I've taken the transformer out for now, so the signal generator and sounding / senor bits are what I'm after.

This might be an interesting project to build too, could get fancy with an Arduino, or just a 555 or the like for basic stuff, hmmm.
