POV – when I first saw this I thought it is a new name for a robot of some kind but when I searched about it – it turned out to be something more interesting. POV means (according to my google search) Persistence Of Vision, this is a condition when something moves faster than what our eyes can decipher – this makes a dot look like a line. It’s the same principle used in a CRT television using super fast scans to make the picture that we see.
There are a lot of POV projects out there but nothing could compete to the workmanship that Kizo put to this spinning light of wonders. It was made using an ATmega324P and 3000 lines of code. The LED array is composed of 40 cyan LEDs driven by a TLC5916 constant current driver. To sense the current position of the propeller Hall Effect sensors are used. And the MOST! And I say the MOST! Outstanding detail about this POV project is that power is wirelessly transferred to the propeller blade by using inductance. Stunned yet?
