           Propeller clocks are nothing new to anyone who has been into electronics for a while. They use an idea called 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 really is not. TV's and Monitors use this method of display, so it's not as uncommon as you might think.
           After having seen so many propeller clock POV videos on Youtube, but no real description of how they work or how to build your own, I set out to make one and document how it was built. The Pyro Propeller Clock POV design criteria was short and sweet: be as simple as possible in order to encourage others to make their own, DIY style.

Purpose & Overview of this project
           The goal of this project is to make a single color propeller clock that uses POV for a cool optical illusion. The propeller should be able to display at every angle 0° - 360° in 1° increments. An IR transmitter receiver pair should be used as a 'home' point for the propeller clock.
           To keep things simple, all parts will be off-the-shelf and modified for our needs. The propeller clock will use two power supplies, one on-board the clock and another to drive the clock motor. The basic operation of the propeller clock will be: starting from 'home', every 1° display a specific LED output that correlates to that location until home is reached again (at 360°).
