Here's our "holiday star" (with a little drone action thrown in):

 
That's a neat Christmas star - did you build that yourself or was it off the shelf?
 
I designed it and had a welder friend assemble most of it (out of aluminum). I wired it all (which took the most time). I also designed the control circuit (for the 3 zones so-as to make it pulsate), and then I found a guy that makes the very same thing for cheaper than I could assemble all the parts!
I had originally hoped it could be seen from very far away... but it's just not that bright (maybe 1 mile). I then thought I'd switch to much brighter lamps (like car head-lights), but all that would be too heavy and the amperage needed would make wiring (and switching) difficult.
Still, it works. :o I can also vary the speed of the pulsation as well as reverse it.
 
Mark - that's a very cool Christmas star. Well done!

(But I hope you're not anywhere near any airport runways ...)

Technically, I'm not supposed to fly and night... and it's very difficult to fly in the dark. This was a very limited flight.
Without any light, the forward and downward sensors don't work, and when one shoots video the beacon light turn off so the darn thing disappears!!! Very unnerving.
