RGB Light Stick Painting doesn’t look very impressive when you watch it in action but with a long exposure and some well timed flashing lights the end result is amazing. The slow fading colors and a simple twirl of the stick looks very nice. The stick has 200 LEDs and is 2 meters tall. Not sure what is powering the unit but I suspect the LEDs are serial and have a microcontroller that reads in data from a SD card and displays the content line by line after being initiated by the push of a button.
Thanks for the tip Jim.
