With the latest light ring, I've split the ring into two parts internally.

So now I can run 3 segments, 4 segments, or 7 segments depending on where I apply power.

This will let me control the brightness without using PWM, and if I extended the shadow mask up to the top, light either only the outside or the inside as well.

The latter would be useful if I'm still getting glare from the camera even with the ring moved way out.

<EDIT>

Well, it worked for the most part.

I need to turn on 3 elements for down looking, and all 7 for the up looking camera to be in the same exposure range and the down looking is still a bit over exposed.   A lot better than it was though...
