| (...) Interesting scenario. Perhaps someone can work up a homebrew bluetooth to IR repeater. Sound crazy? I'll believe anything after what I've seen people accomplish with the RCX, extending it with gameboys and such. I'm sure there are existing (...) (18 years ago, 5-Jan-06, to lugnet.robotics)

| (...) 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)

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)
