Hi ! Thanks a lot for your advices, Steve and Kevin ! Now I know a lot more about the behaviour of the sensor. I think I'm gonna watch his activity through connecting it with my oscilloscope, then I can see exactly how it communicates with the RCX. (...) (22 years ago, 21-Dec-03, to lugnet.robotics)

(...) Hi Thomas, Your english is better than my danish. No need to apologize. There are only two wires between the RCX and the rotation sensor. These wires provide both power and sensor signal. There are two kinds of sensors: passive and active. (...) (22 years ago, 21-Dec-03, to lugnet.robotics)

Hi ! I'm gonna include the lego rotation sensor to a c167 system created by myself and for that I need to know which pins of the lego plug function for what. As far as I know the plug of the rotation sensor has two pins for power supply and another (...) (22 years ago, 21-Dec-03, to lugnet.robotics)

(...) It looks like there isn't as much output drive protection on the RCX2.0 PCBs, unless the MLX10402CB parts have more internal protection than the ELEX 10402As. Does anyone know of any information available about this? I will say now that I (...) (22 years ago, 20-Dec-03, to lugnet.robotics)

If anybody wants some and is going to Brickfest PDX, you can do a phone order for the RCX (so you can buy (...) (22 years ago, 20-Dec-03, to lugnet.robotics)

| | Behavior of the Roomba

Thinking about the one major robotic invention that's creeping into homes these days, it doesn't seem too complex an algorithm. The behavior seems to be as follows: 1) It starts out in an outward spiral motion 2) When it encounters a wall / stairs (...) (22 years ago, 20-Dec-03, to lugnet.robotics)

I bought the brick by itself and I can see how the seller mis-listed it. Live and learn. I got it at a good price so I'll keep it. I still want one with an external jack. Oh well, just have to buy another. :0) Thanks for the info. Mike (22 years ago, 20-Dec-03, to lugnet.robotics)

I bought a RCX 1.0 used on Bricklink to get an RCX with an external jack. The one that arrived is marked 1.0 but has no external jack. I thought all 1.0 units had the jack. Anyone else run in to this? Mike (22 years ago, 20-Dec-03, to lugnet.robotics)
