I have a couple of questions:

The link you put in the video comments http://www.aliexpress.com/item/5M-ws2801...51218.html shows a product for $51US. That doesn't seem unreasonable to me. However, immediately below are products that seem about 1/5 of the price and comparable, like http://www.aliexpress.com/item/Best-pric...14202.html

Is there something that I am missing? Are they in fact functionally different in some way?

Thank you Smile

Yes. It's a little confusing... The actual LED's on most of these strips are all '5050' LED's. The differences is whether or not they are individually addressable and how. The low cost strip you linked to is just 5050's, so they would all light the same color, but you can choose the color. The vast majority and easiest to set up are the WS2801's which use the 5050's, but also have a controller chip for each LED separately on the strip and use PWM signals. There is an easy to use library on from Adafruit that can be loaded onto an Arduino board to drive the strip. There are newer strips that use different signals and the most recent actually have the controller integrated into the actual LED. I know that other's have gotten these working using a couple of different libraries on Arduino or Arduino-like boards but I haven't tried.

So to make a long story short - you are paying more to have the LED's be individually addressable.
