I'm really starting to get my feet wet on a project. I have done essentially a proof of concept that has worked great. Now I'm trying to streamline it into to my final product.
Basically the Lighting aspect is a box that has a 2x8 led array around 4 sides of the box. Just a strip. I did my proof of concept using shift registers to make each LED column addressable. I started playing with some of Adafruits neopixels which have the WS2812Bs embedded in them. I really liked how clean that was with not nearly as many wires. However the Neopixel I feel is not the LED I want to use. I think Through hole may be more my style as the neopixel just didn't have the mcd I was looking for.
So I'm looking for the same concept of that type of communication to address the LEDs. What similar type of hardware is out for controlling the led like that? It does not have to be an all in one like the neopixels.
The neopixel rings use embedded IC's located inside the RGB chips, ws2811? Etc
If you want you can buy those chips or any other chips for driving arrays of leds, or even shift register, how bright, powerful are your LEDs? Current limiting will be tricky unless you have an ic which controlls the current of each LED

Correct, I think the latest release are WS2812b. pretty much the same thing I believe as 2811, just a little better speed.
I would buy the chips loose but I didnt know how common or standard that chip is in potentially production projects. If all goes well this might be something I have mass produced.
I was using some through hole LEDs i got off amazon for the cheap so of course no data sheet. They seem way more bright and would suit my purposes quite well. But I have no been able to find any cheaps that do that type of communication system with just one channel/color. Another variation of the project includes RGB which is what led me to try out the neo pixels, which were neat but not really the type of LED i wanted.
Monocolor or RGB?
2x8x4 = 64 LEDs - just right for a MAX7219. 2 digits on each face.
I offer a little breakout board that makes it easy to wire up 64 LEDs: http://www.crossroadsfencing.com/BobuinoRev17
Thanks for the information. I'm looking for something with a little more efficient wiring like teh ws2812s as the arrrays are all going to be in a line. something like those wheres its 4 or 6 wires wires the whole length.
Also, where does everyone get their leds, Im still searching for the right rgb led for my project.
