Ben Light has really been getting into working with the CNC machine, and it shows with his latest creation, the Turn Table Lamp. The user simply spins this plywood lamp to adjust the brightness. At first I thought there were some electronics involved to achieve this, but it’s actually done with a pair of polarizing lenses — a simple technique that yields a beautiful effect.
We have a TV camera in an office at the US Capitol. The reporters stand in front of a window, so we added a polarizer over the window, and a motorized rotating polarizer over the lens. We can adjust the balance between indoor and outdoor lighting. The filter rotator is controlled via IP or a local switch.
