| | | (...) If you check the legOS group you can see my posts with some extensive analysis of the sensor values for the rotation sensor. There is a patch to make legOS less sensitive to voltage fluctuations and one to debounce the input (which is what (...) (25 years ago, 25-Feb-00, to lugnet.robotics)

| | | | | (...) Ben, I have to go back over the changes, but does legOS sample at the same rate as the standard firmware? The standard rate is about 333hz, so debouncing would likely reduce the effective rate to 166hz, which limits the max rate at which the (...) (25 years ago, 25-Feb-00, to lugnet.robotics)

Yes, debouncing the input halves the effective clock frequency, but the problem is that (...) (25 years ago, 27-Feb-00, to lugnet.robotics)

| | | | I've used old mouse rotation sensors in non-lego projects with some success. They employ a laser counter. The device can be easily connected to a basic stamp. If the counter disk is sealed against contaminantion it works well. Robb, ----- Original (...) (25 years ago, 28-Feb-00, to lugnet.robotics)

| | | | Mmmm, your triggering some thoughts. A mouse is a pretty simple (serial) device Imagine having a robot which has a mouse-ball in a DUPLO block carried over the surface In this way you could record the path the robot has taken. Doing a bit of (...) (25 years ago, 29-Feb-00, to lugnet.robotics)
