I make them, Little something I've been working on and off for a while. They can be either white or I can do in IR if camera can see it.This was the first time for me to test them out while actually flying(my first real night flight). Other flights we could see them from 1.5km away.
They are a bunch of modules I do that run off a 3s battery. One feeds the next and so on. I need to do more boards if I can find a cheap place to do them I'll do more.
