(...) Hi Sebastian I think you're right in your analysis and TLG may silently have fixed the problem, because if you look at the Vision Command installation, you'll find that some of the SDK DLLs are newer in that release. For fun, I copied the DLLs (...) (25 years ago, 21-Mar-01, to lugnet.robotics.rcx, lugnet.robotics)

Hi Rainer, I do not understand quite your point about timing. Regarding to power sharp takes much more than what your RCX can give ( my measuremants show that RCX gives RMS current of )15 mA only this is not going to drive your sharp at all. (...) (25 years ago, 21-Mar-01, to lugnet.robotics.rcx)

(...) Hi Nitin, okay, I see. Sorry, but then your circuit isn't interesting for me. I thought about using Sharp GP2D12 with it, but that won't work. First the Sharps have a current consumption of about 33mA up to 50mA max. Second the Sharps need (...) (25 years ago, 20-Mar-01, to lugnet.robotics.rcx)

Hi Rainer What I do is that switch the power to silected sensor only I do it by using FET. since there is not enough power for all sensors. so when you switch to sensor 2 other sensors are kept off. there is enough power for one sensor since my (...)

I want to use Scout to make Micro-scout's motor rotation, I want to know the speed of this motor when I send a VLL(16) or VLL(20), which power level (1-7) of RCX/Scout is similar to micro-scout's speed?
