| | IR tower for ordinary infrared communication
|
|
Can an old serial IR tower work in Windows ME for ordinary infrared communication, e.g., to another computer with an infrared port? Nothing to do with an RCX or Mindstorms. Just too cheap to buy an infrared communication adapter. My laptop has an IR (...) (23 years ago, 2-May-02, to lugnet.robotics)

That sounds good, but what do I use to drive each beacon, (e.g. send out the coded IR signal and sonar ping). Using a full blown microcontroller like the handyboard for each one would be incredibly expensive and wasteful. I only need a controller (...) (23 years ago, 1-May-02, to lugnet.robotics.handyboard)

The problem with IR is that it tends to get everywhere, reflecting off of surfaces etc, so it's hard to triangulate. May I suggest a related but different approach. Make your beacons out of hybrid IR/sonar transmitters. The beacons will periodically (...) (23 years ago, 1-May-02, to lugnet.robotics.handyboard)
