How can I reduce the volume of my dryer buzzer?
Got a brilliant idea from one of the EE's at work...
iPhone wall adapter as AC/DC converter. Plug tongs fit inside the clips that connected the previous buzzer. USB cable cut and wired to Piezo. The iPhone adapter outputs DC, drops the voltage to 5V which the Piezo can handle, and it work like a charm. My wife can't understand how I did it. I'm a champ (for a day).
