How did you get started?
It started back in the summer of 2010 when I started researching Christmas lights. At that moment I discovered that LEDs had come a long way from my college days and that LEDs that are able to produce any color (RGB LEDs) are very inexpensive. I then started to research RGB LEDs and how they work. It would be almost 30 months before our first display.
What does RGB stand for?
RGB stands for Red, Green & Blue. Each multi-color LED is actually made up of three LEDs; one Red, one Green and one Blue LED. With these three colors, and varying there intensity (brightness), we are able to generate 1 of 16 million colors (Actually 16,777,216 colors). This is the exact same way your TV generates a picture.
Where did you get your parts and pieces?

This year we are using three different type of LEDs:
I currently use these 5v power supplies
