 | | problem with the RCX

|
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, (...) (19 years ago, 11-Jul-07, to lugnet.robotics.rcx)

(...) 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 (...) (19 years ago, 11-Jul-07, to lugnet.robotics.rcx)

(...) _ALWAYS_ assume DC on an actual power adapter (at least in the US). Most AC devices will just use a simple cord, like you'd find on a portable stereo. A handful of devices will need AC power in a non-standard voltage and will use DC-like power (...) (19 years ago, 10-Jul-07, to lugnet.robotics.rcx)

(...) The one used for the RCX may be, but the NXT power supply is sold as a different item, and is listed as a 10VAC adapter vs. the 9VAC adapters used by trains and various other systems. Not that it matters unless you also buy the Li-Ion battery (...) (19 years ago, 10-Jul-07, to lugnet.robotics.rcx)

(...) I now have a Dynamic Instruments 16VAC 375mA, AT&T AC 9V 800mA, and a Black & Decker 9V 200mA from a Dust Buster but it does not say if it is DC or AC, I am assuming AC. Which one should I use? I am hoping the AT&T but the 800mA makes me a (...) (19 years ago, 10-Jul-07, to lugnet.robotics.rcx)

(...) The wall wart for my RCX says "output 10.8VAC 700mA 8w" so it sounds like the rectifier is in the RCX, not the wall wart. (19 years ago, 10-Jul-07, to lugnet.robotics.rcx)

I am looking for the sign of the center pin on the RCX 1.0 power adaptor plug.

NQC: with RCX2, it has a function to display a user defined value. Is there a way to do it with RCX 1.0? How about just to display the current mail value with RCX1.0? Suggestion? Thanks in advance. --Elizabeth (19 years ago, 24-Jun-07, to lugnet.robotics.rcx.nqc)
