Please can you provide a schematic for my rice cooker which will allow this. Also, how do I do it without voiding the warranty? Is it possible to make the beep loud enough to be heard a few floors away, while not annoying my neighbours? If you have the time, I'd love to know of a way to make the beep loud enough so I can hear it when listening to headphones. Oh, and while you're at it, what's the process for making the beep accessible to people with hearing loss? Cheers Pete!
