I've just received some great news from the LEGO Company: they've offered an NXT set as first prize to the winner of this competition! Thank you LEGO! I'm sure the winner will appreciate this as well. (18 years ago, 8-Feb-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

To all, I know how to send RCX messages from the PC over the IR port, but has anyone ever tried and succeeded in sending SPYBOT messages from the PC. I'm trying to write some cross-brick software here and so it is kind of important that I can. I (...) (18 years ago, 8-Feb-07, to lugnet.robotics)

(...) One down side here, is that the "ball-lift" must be shut-off when the bridge is raised, and the controller for the ball lift is on the "bridge" (other) side of the opening.

Hello, Is there any way to clear a spybot message from memory with one command? ClearMessage does not exist in the spybot API. For some weird reason if I use SetSerialData, it causes the brick to go a bit weird. I.E. Random movements etc. Chris (18 years ago, 6-Feb-07, to lugnet.robotics)
