| | | Ok, maybe I'm just out in left field on this one, or maybe someone will actually be inspired to try it out... How about making a color digital camera? Proposal: modify the existing design for the camera by adding on a colored filter, and an extra (...) (24 years ago, 27-Sep-00, to lugnet.robotics)

| | | | (...) Ok, so it's uncouth to reply to my own messages, but more on the color blending: -each filter could be 2 1x2 trans bricks-- the red filter would be green & blue, green would be red & blue, blue would be red & green -you'd also have a 4th (...)

| | | | I tried this a little when I first made my robot using the red bat wings that come with the set, and I couldn't get a good image through one of them. One of the big problems is that the sensor is mostly infrared, with some red sensitivity. I haven't (...) (24 years ago, 28-Sep-00, to lugnet.robotics)

| | | | | First you would need to find a light sensor that detects visible light, not mostly infared light. What type of sensor is this? Andy (...) (24 years ago, 28-Sep-00, to lugnet.robotics)

| | | | (...) Actually, I went home and tried it, and this seems to be the major problem. Even for objects that were totally green or blue, the value with the red filter over the end of the sensor was consistantly higher than the blue or green filtered (...)
