Abstract

Propeller clock is a special kind of circular LED display. It is making use of POV,Persistence of Vision, which means that if something appears in the same spot consistently, at least 50-60 times per second, our brains think that it’s permanently there when it is not. This propeller clock is mechanically scanned and displays in digital format .Made from scrap it can be used anywhere and everywhere and the interesting fact is that its crystal clear display. Maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizing can be implemented through software .The software part of clock works using interrupts and timers.
