It 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 slip it over the red led.
Make sure that the tubing completely surrounds the side of the led for
best results. Then you can either close off the end of the tubing or
leave it open; either way the sensitivity of the light sensor increases dramatically.

| Has anyone successfully found a way (short of paint, or cutting internal wiring) of shutting off the red 'supply light' LED on the Lego light sensor? The supply LED is great for active-detection situations, like line-following, when you need to (...) (23 years ago, 28-Mar-01, to lugnet.robotics)
