coffee maker weight sensor

Hi, new here.. never used an arduino.. but I think I might want to utilize one in a coffee maker hack...

The maker has a sensor that detects when it is finished brewing (i assume) which triggers a timer to shut the maker off after an hour.. I can't disable the timer nor adjust the length of time between initiation and killing the power. This is reaaaallly annoying because it usually takes me an hour to drink my frappuccino! I constantly have to keep powering it again everytime I get a refill.. it's not totally the worst thing in the world.. but when it takes me longer to get another fill... it is sometimes already cold and i have to reheat in the microwave and power the maker on again...any way... my idea is to put an arduino between the sensor circuit and the timer and weighing the pot. I found a flexiforce pressure sensor on sparkfun... but it doesn't say how well it will stand up to heat...if at all.. and to be honest.. I don't even know if this project would be possible with an arduino and sensor... or what all i would need... looking for some advice and maybe some generic description of what i would need and how to go about breaking up the sensor and timer..

Thanks. :)

If you know how to do this, I think it would be lot simpler to simply add in a switch that allows you to turn off the auto-shut-off feature.

Personally, I hate those stupid auto-shut-off features, too. They wouldn't be so bad if they were adjustable. My coffee maker shuts off after 2 hours. I would prefer to be able to set it to 3 or 4 hours.
