(...) You can find light sensor schematics on Michael Gasperi's page: (URL) Using the RCX IR emitter as the illumination source. Don't know (...) Someone has already tried this. You can check Simen Svale Skogsrud's page for an example, with NQC (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

To make a passive light sensor, you can use a design like Michael Gasperi's: (URL) costs only a couple bucks, and works quite well. If you would like better response from your lego light sensor, you can use a piece of black shrinkwrap tubing and (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

Hi Chris, You can turn off the LED with software though you may be a little disappointed with the light sensitivity. The reason the LED is on is because your program has set the sensor to an active sensor. If you set the type to NONE make the mode (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

(...) Maybe. I think RCX2 with NQC has some crude arrays, I haven't looked into them yet, but I might be able to use them to do simple mapping on the RCX. Or something even cruder if I don't have arrays. (...) Ahh. Hmm. I wonder what it actually (...) (24 years ago, 28-Mar-01, to lugnet.robotics)
