I just ordered a 2m NeoPixel strip and all the components to get it running. I got everything wired up and started the strandtest. (see wiring pictures).

After it started, only about half of the strip was lit up, and most of the pixels were white/purple-ish, not an interesting pattern like the code implied. My first thought was that there was a glitch in the code, so I started making modifications there to simplify the cause of the issue. Then I thought it might have been a connection to 2.1mm jack so I started fiddling with the wires there. Things started to get a little better, but still not functioning as expected.
It was after a little while that I noticed I was powered up not with the 5v/4A adapter that I bought for this, but rather the 9v/1A adapter for the arduino. I made the change, but now I'm not even getting the faintest flicker with the 5v power supply. There is still some flickering and lighting up that happens with the 9v but nothing like it's suppose to be.
So is my NeoPixel strip totally shot? Or is there still something else that I might not have configured correctly that will save the day?
