I wish to get my program, which takes images from a camera then picks out objects based on their color, to be able to pick out the nearest of several identical yellow, plastic poles. One idea I have is to shine a colored light in front of the camera. The light will be about 3-4 inches away from the nearest pole, and the second-nearest pole will be about 2.5 feet away. This light will hopefully cause the pole to different than other of those yellow poles. My first question is, what color of light do you suggest I choose in order to get the illuminated pole to stick out against the other poles? There may be red and/or blue objects in the distance, but I can crop those out. The second question is, where can I find LEDs of the appropriate color and brightness that don't need any more than 5 volts. Thanks!

This christmas i'm looking to purchase a pair of bluetooth gamepads, on for myself and one to give to my brother. I'm just looking for a standard bluetooth gamepad priced at around $30 a piece. Does anyone have any recommendations about a specific model?
