 | | FW: Another DIY sensor —Phil Vanderpoel
|
| | | I was throwing a mouse away the other day and instead took it apart to see what makes it tick, well, it's a perfect rotation sensor. I think it will be almost twice as accurate as the lego rotation sensor, more as this project develops. I think it (...) (24 years ago, 18-Nov-00, to lugnet.robotics)
