Please see: (URL) does it mean: "For this function, you will need to program the RCX to send an IR Message (1 through 12) using RCX Code. The Scout will respond to the IR Messages while it is running any program on the display" ? I mean, the Scout (...) (26 years ago, 14-Oct-99, to lugnet.robotics)

Thanks Fred. That got me going in the right direction. But...... When I poke a value into $7000 I can see the corresponding input pin on the l293 react. But it will not stay in the position that I set it to. It will return back to the initial state (...) (26 years ago, 14-Oct-99, to lugnet.robotics.handyboard)

Just a note. The German Marklin model train company offers a wireless camera built-in in a 'tiny' H0-scale train car. It's expensive but it prooves the technology is available at a consumer scale. Eric (26 years ago, 14-Oct-99, to lugnet.robotics)

The scout has some pre-programmed routines that are activated by receiving a message from the RCX or the IR tower. I listed them in a post to this group, I think the thread was something like "RCX VS the Scout". What I found was that the scout will (...) (26 years ago, 14-Oct-99, to lugnet.robotics)

(...) Absolutely not. There is no way that this list is accurate. From what I hear, Lego is not doing any more Episode 1 sets at all. So you can cross off the AAT, MTT and the Two Kaadus right away. Also, multiple mindstorm sets? No possible way. To (...) (26 years ago, 14-Oct-99, to lugnet.robotics)

| | Rotaion Sensor Sampling Speed?
|
|
Hi all, I'm putting together a mazebot for Mindfest, and ran into a bit of a funny with the rotation sensor. I THINK it has to do with the sample speed, but I'm not positive. I'm using pbFORTH and sampling the rotation sensor in a tight loop. The (...) (26 years ago, 14-Oct-99, to lugnet.robotics)
