This device consists of 2 parts - a photosensitive transmitter (which is placed outdoors), and a receiver which is worn about the person in the form of a bracelet/necklace etc. When darkness falls, the transmitter sends a signal to the receiver, which then goes "ding, dong". This will advise the wearer that night has fallen, and their fast can be broken. Particularly useful for blind muslims, or muslims who are in a room with no windows.

I'd say that the religious nature of Ramadan would make it unacceptable for people to be making their own decisions about the ending of a day. My experience of Ramadan included listening for the evening announcement from the mesjid (mosque). Maybe you could arrange for a cell phone call from the local decider (but don't tell him you've been making bad puns about Ramadan).

Just give the end-of-the-day-decider-guy a big red you-can-eat-now button which transmits to all the ramadan-a-ding-dong's in his jurisdiction.
