| Hi Brian, I find your question very interesting. I do not have an audio analyzer, but I have a few ideas so you can extend your hunt. I'm told that you can get software that lets you use your sound card as an oscilliscope. All you need is a (...) (20 years ago, 18-Aug-04, to lugnet.robotics)

| Hi Brian, I examined the RCX ROM sound routine, and it provides a lower bound of frequency 31 (matches what your ears told you), and an upper bound of 20000 (also as you noticed). I'm not sure about the sound hardware, but you might be able higher (...) (20 years ago, 18-Aug-04, to lugnet.robotics)

| We now have an infrared / radio repeater system. It can do PC <--> RCX or RCX <--> RCX. (No networking yet!) The system translates the IR data to RF data and vice versa.
