  1. A ring sight that shows concentric rings (usually and incorrectly called Newton rings) that move with the wearer's head to stay centered on the target is a complex piece of optical engineering, involving multiple layers of polarizing media ("polaroid") and optically anisotropic media (such as calcite) cut perpendicular to its optic axis. The thickness of the layers is critically important. I doubt that it's an easy do-it-yourself project. (I used to teach this stuff)

  6. My Altitrack has started behaving erratically. The battery is fine so it's not that. The digital readouts on the back are OK, but the analog needle on the face goes (consistently) to the wrong place, about 4,700ft, when I turn the unit on. If I remove and replace the battery, the needle ends up consistently around 16,000ft. If I reset the unit the needle goes all the way around the face and ends up consistenly in the wrong place. I have discovered that the following sequence gets the needle to the zero: reset, turn the unit off, turn it on again. It then stays correct for the rest of the day, but after it shuts down, the next morning when I turn it on the needle goes back to 4,700ft ????? ...
