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)

@gvy_dvpont ... Why did they design it the original way? Who thought that was a good idea?!

Guy Dupont

These are such beautifully simple machines. It's got a heating element, a fuse and an alarm. when the water evaporates, the plate gets hot enough to open the fuse. The power is then rerouted through the alarm. So you control cooking length simply by adding more/less water!

All I did was replace the alarm (which took 120V AC directly) with a little AC-DC module (basically what's inside a phone charger) and so it sends out 5V DC when its done cooking. I'm knocking it down to 3.3 and hooking it up directly to the the music box.

120V AC -> 5V DC module hooked up to a LM1117T-3.3 voltage regulator, whose output is hooked up to an electromechanical music box module.

@gvy_dvpont The original alarm is so horrible. Why would they do that lol

@MLE_online feels like they just repurposed hardware from some old early digital alarm clocks lol
Good sound to wake you up, bad sound to tell you about your egg being ready.

@timonsku It also sounds like phone alert to tell you that there's a severe weather warning and to take shelter

@gvy_dvpont
I know very similar sound. For some reason this seems to be a best practice among egg cooker manufacturers.

@gvy_dvpont Much improved! The original sounds like you should grab your egg and run to your battle station.
