After some serious hacking and shoving things inside of a slightly larger tube, I did a successful spin of the whole thing, battery and all. Problem? The LEDs are way too bright to be taking a video at 10 feet away. So these are running at 1/8 brightness. Video was taken at 30fps.
What’s the rpm of the light bar?
Whatever my hand is spinning it at. 
I don’t see any gap at all between the pixels. Very nice!
1mm between the physical LEDs, a little bit more between the actual circle that illuminates. They’re 5050 SMD LEDs. Bright as hell.
