Hi. I am putting together a Handyboard and have been having success until it came time to test the bootstrap mode. The interface board's voltages check out and it blinks as it attempts to download. I am using an E1 and the Mac 6811 downloader. The E (...) (22 years ago, 9-Feb-02, to lugnet.robotics.handyboard)

The LEGO shaft encoder and light sensor are active sensors that need a special circuit. The Expansion Board for the HB provides this ckt and the requisite drivers. Your simplest path to using these with the HB is to get an Exp Bd. Barring that, you (...) (22 years ago, 7-Feb-02, to lugnet.robotics.handyboard)

Another question: How can I get the handy board to read from the lego rotation sensor and the lego light sensor? I can get the touch (...) (22 years ago, 7-Feb-02, to lugnet.robotics.handyboard)
