Hello,
I've been looking for a led strip that can be cut down to 1 led per segment. Most I've seen are 3 per segment. I need this because the leds will backlight holes that aren't perfectly spaced and a ribbon solution is easier to implement that some kind of xxxplexing or home run.
I found this: http://www.amazon.com/Addressable-Waterproof-WS2801-Connectors-Included/dp/B008F05N54/ref=pd_rhf_se_p_t_3
which is okay and a good price, but I have no idea what the lumens are on that LED.
Then there's Pololu's solution which is bit-bang:
But my controller is using interrupts and a bunch of other things and I don't want to get into a situation where timing will be an issue. I'd rather clock and latch or SPI (if I can ever figure that out).
Right now I'm using ShiftBrites but they're pretty expensive (~$5/ea compared to <$1/ea). They are really bright, though.
So that's where I am.. is the Amazon unit (no name x) A) bright enough and B) actually a good price?
Further info: I'm driving about 80~90 LEDs, hopefully updating every 30~50ms.
I scoured Ebay looking for this product but all I found was 5050s, which are 3/segment.
Thanks
