We've got this cheap egg cooker that plays the loudest, most terrifying alarm you've ever heard when it's done cooking. My wife requested that I make it "less aggressive" so I hacked it into the most gentle egg cooker of ALL TIME
(warning: probably loud)
@iris First of all, obligatory: please be careful!! Don't go digging while the device is plugged in. What I did was kinda dangerous TBH (not sure what your comfort level is with electronics, just making sure).
Most alarms/buzzers I've ever seen are round/black with a hole in the middle:
