From: "user9253" <fran4sew@banyanol.com>



> Bob and all, I have a EIectronics Intermational clock that will ground a line
when it reaches 0:00. I would like to hook a chime to the line and run it to
my audio panel. Other than EIs tone generator, is there an easy way to do this?


Here is a circuit by Forrest M. Mims, III that makes a tone when the input goes
low.
