(...) Is the RCX still working? Does it "get hot" when it's running an unloaded motor? I would have thought that the 500 mA limit within the RCX case would prevent this, but perhaps it's marginal for some plastic piece "nearby". If the RCX is dead, (...)

(...) Strange indeed, But, that's what we experienced. I have faith that more than 5 pairs can communicate all at the same time. On the other hand, maybe we used up all the channels. Perhaps like in RC airplanes, we ran out of crystals. (17 years ago, 11-Jul-07, to lugnet.robotics.nxt)

Starting with the original NXTGCC source, if I disable binsert in the makefile, the firmware crashes on boot. The firmware development which I am doing will probably increase the size of the firmware by around 20KB, so I'm wondering if I need to do (...)

One of my students accidently left a tied up gear train running for a while, i.e. In the midst of running a RCX, the case not only gets very hot, but also has a very strong plastic burning smell. At first I thought it is due to the stuck gear train, (...) (17 years ago, 11-Jul-07, to lugnet.robotics.rcx)

(...) ... (...) Just to be clear, you got 5 pairs of master/slave NXTs to communicate as pairs? But if you added a 6th pair, then those two could not connect to each other? That's really strange... Ralph (17 years ago, 11-Jul-07, to lugnet.robotics.nxt)

I've reached a goal this summer. Last week, 5 kids got into Bluetooth and made simple remote controls. I provided two simple NXT-G programs, BTSend on the Master NXT Remote Control and BTRecv on the Robot Slave. BTSend uses the left and right NXT (...) (17 years ago, 11-Jul-07, to lugnet.robotics.nxt)

LEJOS OSEK ver.1.03 was just released. (URL) 1.03 includes a minor bug fix and a new interesting application example which is called NXT GT. NXT GT is a Bluetooth based R/C car and you can control the NXT GT by using PC analog game pad controller! (17 years ago, 11-Jul-07, to lugnet.robotics.nxt)

(...) Whoops, I missed that there was a third option. I concur with this, as it's both the right voltage and confirmed AC. The mA rating, BTW, is a capacity rating, so it will work for anything that draws 800mA or less. The NXT adapter is rated for (...) (17 years ago, 11-Jul-07, to lugnet.robotics.rcx)
