I had one of them drip coffee makers that ground the beans into a filter. You could set it with an alarm. Problem was the hot plate turned off after about 25 mins (and I wanted the jug warm a good bit longer). I found if I switched the power off (at the wall) and back on again quickly, the hot plate would stay hot indefinitely. I think this is a common way to bypass a certain type of timer, I can't even remember why I tried it out, but it works!
