|
| A question from germany (sorry for my bad english). Is anybody out there, who connected the IR tower with the FIRST PowerBook G3 (little colored apple logo, built in 1997, family number M3553, us-nickname KANGA, 250 MHz)? This PowerBook has only one (...) (22 years ago, 22-Jan-03, to lugnet.robotics.rcx)

| The Lego firmware cuts power for about 200uS, with a period of 3mS. So most sensors have to have enough capacitor based power storage for the full 200uS and be able to run on about 93% duty cycle. (The rotation sensor is one of the devices on the (...) (22 years ago, 19-Jan-03, to lugnet.robotics.rcx.legos)
