I recently ordered 5m of the addressable RGB LED strip
, and I've gotten it working great, powered by my Raspberry Pi (super simple with the SPI driver).
There is, however, one caveat. When unrolled, there's one LED right in the middle for which the green simply doesn't work. If I press on it (even very, very lightly), it begins to work, which makes me suspect that one of the connections is loose in there, either on the chip or one of the resistors, I'm not sure -- it's hard to see clearly. Here's a video showing the problem: http://youtu.be/4Txgf4lEuJI
And here are a couple pictures:http://i.imgur.com/BeRLv.jpg
In this picture, the entire strip should be yellowis (green + red), and it is, except for this one little sad LED http://i.imgur.com/vMHiy.jpg
And here's a closeup of the chip/resistors in question. It seems there's a bit of dust or something in there; that's why it loos so nasty. But this is the best I could get.
