I picked up a Christmas light at walmart and trying to find info about it. What interested me is that for $8 I got 15 RGB LEDs, each with it's own little pcb and it seems like they can be controlled individually! Of course it's not as simple as reading the specs because I haven't found any (did google the numbers found) and the IC is a black blob so no help there.<br>
I opened up the first and last one to take some pictures. The first one has 5V feed on the upper row marked "DI", the bottom row marked "DO" has 3 wires going to next light where it comes in on the "DI" row, out on a "DO" and my guess is that it goes on like that to the end.<br>
I took some pictures of it that can be seen at http://flickr.com/gp/henahadu/73436S/ <br>
My question is - anyone seen anything like it ? Any clue on where/how I can find more info? Somewhere else to ask ?<br>
