Hi, this seems to be a very good idea for a new RCX sensor. Reading the Sharp data sheets for their infrared distance sensors I want to write some facts about.

(...) you won't be able to use LNP - those packets are completely different from the Lego firmware ones. You'll need to write bytes directly to the serial port (I'm not sure what support there is for this in legOS since once you start munging the (...) (26 years ago, 27-Sep-00, to lugnet.robotics.rcx)

That sensor looks very cool. It seems like it could run off of the standard brick voltage too, unlike the sonar sensor which would need an additional battery pack. And it is cheap. Rig it up! (...) (26 years ago, 25-Sep-00, to lugnet.robotics, lugnet.robotics.rcx)

I'm pretty sure that it doesn't come in any sets. I know you can order it from Shop@Home. I purchased my from eBay and got a much better deal than through S@H. LEGO tech support said the sensor was accurate to the integer. for example, it's 71 (...) (26 years ago, 22-Sep-00, to lugnet.robotics.rcx)
