Hi all, I am looking at buying the book - Extreme Mindstorms. Any comments welcome. I am an advanced user, and am looking for some ideas. For those who have it, what customized sensors do they provide instructions to build? Dave (24 years ago, 25-Mar-01, to lugnet.robotics)

I think that a pBrick like RCX or CM isn't fast enough to detect PWM cycles. Don't know the speed of a legOS program. On top of that, I think that the sensors detect resistance, not voltage. You can do this test yourself, using two RCX's or one RCX (...) (24 years ago, 26-Mar-01, to lugnet.robotics)
