After helping my son’s school with their FLL team last year I got the wild idea to start my own FLL team this past year. I had no idea what I was in for but I knew that I wanted to put together a team that was dedicated to learning about FLL and (...) (17 years ago, 11-Feb-09, to lugnet.general, lugnet.robotics, FTX)

Over the nearly 10 years that I've had a MINDSTORMS related website I've noticed that my most popular homebrew sensor is the one for Galvanic Skin Response. This type sensor is used in lie detectors and biofeedback devices. I recently updated the (...) (17 years ago, 11-Feb-09, to lugnet.robotics)

Hi, I can't find my lego mindstorm IR tower and I was thinking if it is possible to hack a generic IR dongle ( (URL) from a computer so that it can communicate with the RCX brick. Is that possible? How do I do this? Thanks (17 years ago, 5-Feb-09, to lugnet.robotics)
