SCHOOL BELLY CONTROLLER - PLATE AND PROGRAMMED LAYOUT
To control the school bell, a microprocessor was used, which guarantees that the length of all lessons and breaks between them will be in line with the expectations of teachers and students. The system uses a battery backup time and non-volatile memory, so that no accidental power supply failure will cause the need to re-programming the switch-on times.
The controller works in one-day mode. It allows programming the length and number of lessons, length of breaks and the duration of the bell operation. After specifying the start time of the first lesson, all other parameters (for the daily timetable) are automatically calculated.
The system is easy to assemble, reliable in operation and seems indispensable in every school.
The device is especially recommended for lovers of punctually beginning and ending lessons, teachers and all students

The Clockwork Universe theory favored by 17th C deists held that the Earth and the heavens, and all their motions, were like a giant clock, with God as the Clockmaker. Newton\'s three laws of motion and the principle of universal gravitation were thought to be sufficient to explain phenomena of any kind, using mechanical conceptions. At Ugears we love mechanical conceptions! And so with a nod to Isaac Newton, we present the Sky Watcher Tourbillon Table Clock, a fascinating combination of imaginative celestial observatory and functional table clock! UGears 70162
