| Hi, I don't think I've seen it here yet, but apparently LEGO is finally releasing version 1.1 of the NXT software. It will be available on Shop@Home: (URL) So far it seems it's not available in all countries yet, but a phone call might work. To me (...) (19 years ago, 9-Oct-07, to lugnet.robotics.nxt, FTX)

| (...) You are right, the main limitation probably comes from wall wart... You are essentially right for the 0.7A current (though it is not hard limit, rather a safety one). Philo (19 years ago, 9-Oct-07, to lugnet.lego, lugnet.robotics.nxt, lugnet.trains)

| (...) The Australian LEGO wall wart is marked 10V @ 7VA on the secondary. I don't recall all the stuff I learnt about the relationship between VA and W, but that seems to me to indicate about 0.7A. I believe this generally reduces as load increases, (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt, lugnet.trains)

| (...) Philo kindly corrected me, pointing out that the NXT outputs are regulated down to 1 A, so you couldn't run a dual-truck train all the way to stall. You could still get a good bit of the way there, however. Does anyone know what the peak (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

| (...) Ah, thank you - so running two stalled train motors would exceed the NXT output, but running one train motor up to a stall conditions should be fine. Out of curiosity, along with the output limitations on the NXT (1 A) and RCX (500 mA), does (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)
