Adafruit does have a new strip that only has one data wire, so perhaps it is similar:<br><a href="http://www.adafruit.com/products/1138">http://www.adafruit.com/products/1138</a><br><br>Interesting that there doesn't seem to be master controller? That Adafruit lights use a microcontroller to send the patterns to pixels, (entering at the first pixel's DI and shifting out to the next one w/ DO and so on).<br>
<br>Let us know if you manage to control it.<br><br>Andrew<br><br><div class="gmail_quote"><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I picked up a Christmas light at walmart and trying to find info about<br>
it. What interested me is that for $8 I got 15 RGB LEDs, each with it's<br>
own little pcb and it seems like they can be controlled individually! Of<br>
course it's not as simple as reading the specs because I haven't found<br>
any (did google the numbers found) and the IC is a black blob so no help<br>
there.<br>
I opened up the first and last one to take some pictures. The first one<br>
has 5V feed on the upper row marked "DI", the bottom row marked "DO" has<br>
3 wires going to next light where it comes in on the "DI" row, out on a<br>
"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<br>

My question is - anyone seen anything like it ? Any clue on where/how I<br>
can find more info? Somewhere else to ask ?<br>
