Tonight I soldered the parts together, Here's an action shot. First, placed the LED's in the right order. each LED has a flat side, and the board shows a flat side. make sure you align those. then, split each pin each way, so that they alternate, this makes it slightly easier to slip them through in the right order. it take a little bit or fussing with it, but once you get the feel for the first one the next ones are easy. 

Added a little rosin flux, then soldered them in and clipped the long leads. 

And oh so beautiful:

the white board really makes the light pop. this board is a basic trinket, using the standard adafruit instructions for a trinket and neopixel; https://github.com/adafruit/Adafruit_NeoPixel/tree/master/examples/strandtest

I just updated that code to use pin 1. Read up on AdaFruits Uber guide to learn more about the NeoPixels.

next up, writing some custom code for circuit python example to go with this board!.
