| (...) I thought of this yesterday. If I end up as one of the 100 people who get it early, I'll connect a LEGO USB tower to the NXT USB port and see if I can get the NXT to control the tower. I assume I'll need a USB type-A to type-B converter. As (...) (18 years ago, 6-Jan-06, to lugnet.robotics, FTX)

| If Lego obeys the USB standard and uses fullsize receptacles, it'll be a "B" type connector on the NXT. Hence, you'd need a B-male to A-female cable, which is "illegal" according to the USB standards. You might hack up your own, but that's (...) (18 years ago, 6-Jan-06, to lugnet.robotics)

A custom driver for the tower would probably have to be written for the tower to run from within the NXT. I (...) (18 years ago, 6-Jan-06, to lugnet.robotics, FTX)

The usage of the USB port is for fast download from PC to (...) (18 years ago, 7-Jan-06, to lugnet.robotics, FTX)

| I know everyone is psyched about the NXT, but on another topic-- does anyone have experience with the new compass sensor from Hitechnic? In particular, I'm wondering what chip they use, and how sensitive it is to non-horizontal placement. Also, can (...) (18 years ago, 8-Jan-06, to lugnet.robotics)
