Project title: Servo Driven 7 Segment Display
Project Creator: Jim H
Short description: An analog giant 7 segment display made with cardboard and servo motors that displays numbers by rotating brightly colored pieces of cardboard rather than lighting up LEDs.
Response: I can see a lot of cool uses for this module within a larger project. It would be useful for displaying large numbers in some application where the digits themselves do not change very often, as unlike a light, it uses most of its power only when changing states.
One obvious problem with this design is that the number being displayed might be unclear when the module is viewed at an angle. Since the segments just get rotated 90 degrees, they would still be visible from the side or from the top even when they are “turned off”. A possible solution could be to rotate the segments 180 degrees.
