Fidget spinners were everywere one year back. It was an explosion of these things. But this is not a normal fidget spinner. It has POV display integrated. POV stands for persistance of vision. The LEDs are blinking very fast in the same exact position, and the persistance of that blink will create shapes in the air while the fidget is spinning. By taht we can create text or other shapes. The more LEDs has our POV display, the better would be the "resolution" of the letters.
YouTube channel presented his work on this project. The PCB has everything it needs to create the POV effect but it is also in the shape of a fidget spinner and has a place for a 22mm bearing.
