Hi. Please forgive my total ignorance here. My daughter is working on a project and I'm trying to put her on the right track. The project is: Build a mechanical "mirror". The mirror is composed of maybe 1000 small square or rectangular pieces of something. Each of these pieces is a pixel in the image that is produced on this mirror. Each piece must be controlled independently (on or off - tilted or not - in or out - etc.) by a computer. The computer will be receiving the incoming image from a video camera. So a person stands in front of the camera and the mechanical mirror responds by turning each pixel on or off (or tilting or not). So...I'm thinking that she might start by looking at the world of servos. Any thoughts as to a good place to check out servos that could, let's say, push a wooden tile up and then release the tile. (Thus the tile would be able to look "appear" two different ways.) I'm thinking that she needs a servo that can do linear motion. Or, in other words, how can we translate the circular motion of servos into a linear motion that could push the tiles forward or backward. She needs to just get one tile going to test. She has limited access to "build anything from scratch" tools, so we want to get a hold of something that is pre-made to do the linear thing. Like a servo, a gear thingo and a rod attached to the gear thingo. Any "getting started" help on this would be most appreciated. Thanks, Rich the Dad.
