Wow, people are following my projects! I'm flattered!
I'm blown away by the fact that a screenshot from LibreCAD could generate some interest. Still waiting on the Arduino clones from GearBest. Kinda sad that it's taking longer than I expected, especially since my NeoPixels from Mr Zhang came in already.
Wow, these things are TINY. I have a few ideas now that I've seen them firsthand, and handled them.. and soldered a few together in a chain.
The pads look like they might be 0.10 inch spacing. I'm going to try putting pins on them and using a socket. There are several ideas that have popped up since they arrived, including a Destroid/Daft Punk bit of costume.
Now that the holidays are over, I actually will have some time to experiment and build before the marryin' season kicks off and we're busy again.
