I didn't take the time earlier to try to find them while at work, but now that I'm home took the time to actually look them up.<p>NeoPixels are known everywhere except that other vendor as WS2812, and DotStars are known everywhere except that other vendor as APA102. These are actually IMHO the more "correct" name because they reference the driver chip embedded in the LED package, but unfortunately aren't as easy for me to remember.</p><p>All that said, neither of these are the only addressable RGB LEDs on the market. It's just that these are the ones with the best Arduino support. (Though I could be wrong...)</p><p>Back to the project at hand, I would suspect that WS2812s would work better than APA102 because of simpler wiring. Sewable projects are really best suited to circuits that can be done as if they are single sided boards. You can cross nets, but that gets tricky and error prone.</p></p>

Super!<p>Can you tell us who did the music? It was appropriate and nice also. It was so fantastic that I won't even mention the old joke about "New Age - Rhymes with Sewage" ok? Oh, I'm sorry, it just slipped out.</p><p>Totally seriously, great job, Feldi!</p></p>

The LilyTwinkle also comes with animations pre-loaded but they were not the best ones for this design. The LilyTiny has more subtle animations that look like twinkling starts, while the LilyTwinkle has more of a pulsing firefly animation.<p>Love your ideas for pushing this project further, thanks for sharing! :)</p></p>

Looking at the flashing pattern in the video, it seems that you are using the <a href="https://www.sparkfun.com/products/11364" rel="nofollow">LilyTwinkle</a> instead of the <a href="https://www.sparkfun.com/products/10899" rel="nofollow">LilyTiny</a>. Otherwise different parts of the constellation would be blinking differently.<p>Other than that, really good project idea and good video documentation of all the steps.</p><p>My thought on how to super-charge this project (and make it more complicated and expensive) is to have the µC (re-prgrammed LilyTiny/LilyTwinkle or other small, sewable board) drive programmable RBG LEDs. (Something like what Adafruit calls NeoPixel or DotStar, I forget their "correct" names). Have a flicker routine flickering an array of values that mimic the colors and relative brightness of the actual stars in the constellation. A bonus is this enhancement would probably generate several bald yaks. ;-)</p><p>Even more complicated, expensive, and probably more bald yaks:
Hide a small solar cell between the fabric layers that powers it's own comparitor to switch a sleep interrupt pin of the µC to prolong the battery by turning it off when there is enough light.</p></p>
