Another trip to Uno (a local discount store), another meteor light find. This one is a large tube with only 30 LEDs - 3 LEDs per bank vs. 4 LEDs, only 10 banks vs. 12 banks - but they are multi-colored (red, green and blue) instead of either just all white or all blue. It still uses the UCS1212 IC in the design, but done just a _little_ bit differently. And it's a little cheaper than the larger, 48 LED tube (p189 vs p219 - p30 difference which is about US$0.75). Here's the schematic:
And here's a direct link to the UCS1212 Datasheet (PDF) - be forewarned, it's in Chinese.
