Garden Variety:persistence of vision

I found some wonderful example of POV leds on line. Sites like DIY Live and MAKE magazine had excellent examples. I was delighted to find these small programmable fans that I could take apart and run using a microcontroller and sensor. I am now working on my own 6 inch version. These new fans will allow cell phone users to text directly to them.

This work continues my interest in scientific principles and the integration of high and low technologies
